I have some parameters that I want to POST form-encoded to my server:
{
'userName': 'test#gmail.com',
'password': 'Password!',
'grant_type': 'password'
}
I'm sending my request (currently without parameters) like this
var obj = {
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
},
};
fetch('https://example.com/login', obj)
.then(function(res) {
// Do stuff with result
});
How can I include the form-encoded parameters in the request?
You have to put together the x-www-form-urlencoded payload yourself, like this:
var details = {
'userName': 'test#gmail.com',
'password': 'Password!',
'grant_type': 'password'
};
var formBody = [];
for (var property in details) {
var encodedKey = encodeURIComponent(property);
var encodedValue = encodeURIComponent(details[property]);
formBody.push(encodedKey + "=" + encodedValue);
}
formBody = formBody.join("&");
fetch('https://example.com/login', {
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8'
},
body: formBody
})
Note that if you were using fetch in a (sufficiently modern) browser, instead of React Native, you could instead create a URLSearchParams object and use that as the body, since the Fetch Standard states that if the body is a URLSearchParams object then it should be serialised as application/x-www-form-urlencoded. However, you can't do this in React Native because React Native does not implement URLSearchParams.
Even simpler:
fetch('https://example.com/login', {
method: 'POST',
headers:{
'Content-Type': 'application/x-www-form-urlencoded'
},
body: new URLSearchParams({
'userName': 'test#gmail.com',
'password': 'Password!',
'grant_type': 'password'
})
});
Docs: https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/fetch
Use URLSearchParams
https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams
var data = new URLSearchParams();
data.append('userName', 'test#gmail.com');
data.append('password', 'Password');
data.append('grant_type', 'password');
Just did this and UrlSearchParams did the trick
Here is my code if it helps someone
import 'url-search-params-polyfill';
const userLogsInOptions = (username, password) => {
// const formData = new FormData();
const formData = new URLSearchParams();
formData.append('grant_type', 'password');
formData.append('client_id', 'XXXX-app');
formData.append('username', username);
formData.append('password', password);
return (
{
method: 'POST',
headers: {
// "Content-Type": "application/json; charset=utf-8",
"Content-Type": "application/x-www-form-urlencoded",
},
body: formData.toString(),
json: true,
}
);
};
const getUserUnlockToken = async (username, password) => {
const userLoginUri = `${scheme}://${host}/auth/realms/${realm}/protocol/openid-connect/token`;
const response = await fetch(
userLoginUri,
userLogsInOptions(username, password),
);
const responseJson = await response.json();
console.log('acces_token ', responseJson.access_token);
if (responseJson.error) {
console.error('error ', responseJson.error);
}
console.log('json ', responseJson);
return responseJson.access_token;
};
No need to use jQuery, querystring or manually assemble the payload. URLSearchParams is a way to go and here is one of the most concise answers with the full request example:
fetch('https://example.com/login', {
method: 'POST',
body: new URLSearchParams({
param: 'Some value',
anotherParam: 'Another value'
})
})
.then(response => {
// Do stuff with the response
});
The same technique using async / await.
const login = async () => {
const response = await fetch('https://example.com/login', {
method: 'POST',
body: new URLSearchParams({
param: 'Some value',
anotherParam: 'Another value'
})
})
// Do stuff with the response
}
Yes, you can use Axios or any other HTTP client library instead of native fetch.
var details = {
'userName': 'test#gmail.com',
'password': 'Password!',
'grant_type': 'password'
};
var formBody = [];
for (var property in details) {
var encodedKey = encodeURIComponent(property);
var encodedValue = encodeURIComponent(details[property]);
formBody.push(encodedKey + "=" + encodedValue);
}
formBody = formBody.join("&");
fetch('http://identity.azurewebsites.net' + '/token', {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/x-www-form-urlencoded'
},
body: formBody
})
it is so helpful for me and works without any error

You can use FormData and URLSearchParams to post as application/x-www-form-urlencoded with the example below:
If you have a form:
<form>
<input name="username" type="text" />
<input name="password" type="password" />
<button type="submit">login</button>
</form>
You can add use the JS below to submit the form.
const form = document.querySelector("form");
form.addEventListener("submit", async () => {
const formData = new FormData(form);
try {
await fetch("https://example.com/login", {
method: "POST",
headers: {
"Content-Type": "application/x-www-form-urlencoded",
},
body: new URLSearchParams(formData),
});
} catch (err) {
console.log(err);
}
});
*/ import this statement */
import qs from 'querystring'
fetch("*your url*", {
method: 'POST',
headers: {'Content-Type': 'application/x-www-form-urlencoded;charset=UTF-8'},
body: qs.stringify({
username: "akshita",
password: "123456",
})
}).then((response) => response.json())
.then((responseData) => {
alert(JSON.stringify(responseData))
})
After using npm i querystring --save it's work fine.
Just Use
import qs from "qs";
let data = {
'profileId': this.props.screenProps[0],
'accountId': this.props.screenProps[1],
'accessToken': this.props.screenProps[2],
'itemId': this.itemId
};
return axios.post(METHOD_WALL_GET, qs.stringify(data))
If you are using JQuery, this works too..
fetch(url, {
method: 'POST',
body: $.param(data),
headers:{
'Content-Type': 'application/x-www-form-urlencoded'
}
})
You can use UrlSearchParams and then do a toString() like so:
Here is a simple way of doing it:
fetch('https://example.com/login', {
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
},
body: new UrlSearchParams(...{
'userName': 'test#gmail.com',
'password': 'Password!',
'grant_type': 'password'
})
.toString()
})
.then(res => {
//Deal with response:
})
According to the spec, using encodeURIComponent won't give you a conforming query string. It states:
Control names and values are escaped. Space characters are replaced by +, and then reserved characters are escaped as described in [RFC1738], section 2.2: Non-alphanumeric characters are replaced by %HH, a percent sign and two hexadecimal digits representing the ASCII code of the character. Line breaks are represented as "CR LF" pairs (i.e., %0D%0A).
The control names/values are listed in the order they appear in the document. The name is separated from the value by = and name/value pairs are separated from each other by &.
The problem is, encodeURIComponent encodes spaces to be %20, not +.
The form-body should be coded using a variation of the encodeURIComponent methods shown in the other answers.
const formUrlEncode = str => {
return str.replace(/[^\d\w]/g, char => {
return char === " "
? "+"
: encodeURIComponent(char);
})
}
const data = {foo: "bar߃©˙∑ baz", boom: "pow"};
const dataPairs = Object.keys(data).map( key => {
const val = data[key];
return (formUrlEncode(key) + "=" + formUrlEncode(val));
}).join("&");
// dataPairs is "foo=bar%C3%9F%C6%92%C2%A9%CB%99%E2%88%91++baz&boom=pow"
Just set the body as the following
var reqBody = "username="+username+"&password="+password+"&grant_type=password";
then
fetch('url', {
method: 'POST',
headers: {
//'Authorization': 'Bearer token',
'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
},
body: reqBody
}).then((response) => response.json())
.then((responseData) => {
console.log(JSON.stringify(responseData));
}).catch(err=>{console.log(err)})
You can use react-native-easy-app that is easier to send http request and formulate interception request.
import { XHttp } from 'react-native-easy-app';
* Synchronous request
const params = {name:'rufeng',age:20}
const response = await XHttp().url(url).param(params).formEncoded().execute('GET');
const {success, json, message, status} = response;
* Asynchronous requests
XHttp().url(url).param(params).formEncoded().get((success, json, message, status)=>{
if (success){
this.setState({content: JSON.stringify(json)});
} else {
showToast(msg);
}
});
In the original example you have a transformRequest function which converts an object to Form Encoded data.
In the revised example you have replaced that with JSON.stringify which converts an object to JSON.
In both cases you have 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8' so you are claiming to be sending Form Encoded data in both cases.
Use your Form Encoding function instead of JSON.stringify.
Re update:
In your first fetch example, you set the body to be the JSON value.
Now you have created a Form Encoded version, but instead of setting the body to be that value, you have created a new object and set the Form Encoded data as a property of that object.
Don't create that extra object. Just assign your value to body.
wrapped fetch in a simple function
async function post_www_url_encdoded(url, data) {
const body = new URLSearchParams();
for (let key in data) {
body.append(key, data[key]);
}
return await fetch(url, { method: "POST", body });
}
const response = await post_www_url_encdoded("https://example.com/login", {
"name":"ali",
"password": "1234"});
if (response.ok){ console.log("posted!"); }
For uploading Form-Encoded POST requests, I recommend using the FormData object.
Example code:
var params = {
userName: 'test#gmail.com',
password: 'Password!',
grant_type: 'password'
};
var formData = new FormData();
for (var k in params) {
formData.append(k, params[k]);
}
var request = {
method: 'POST',
headers: headers,
body: formData
};
fetch(url, request);
I'm trying to POST a JSON object using fetch.
From what I can understand, I need to attach a stringified object to the body of the request, e.g.:
fetch("/echo/json/",
{
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
method: "POST",
body: JSON.stringify({a: 1, b: 2})
})
.then(function(res){ console.log(res) })
.catch(function(res){ console.log(res) })
When using jsfiddle's JSON echo I'd expect to see the object I've sent ({a: 1, b: 2}) back, but this does not happen - chrome devtools doesn't even show the JSON as part of the request, which means that it's not being sent.
With ES2017 async/await support, this is how to POST a JSON payload:
(async () => {
const rawResponse = await fetch('https://httpbin.org/post', {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify({a: 1, b: 'Textual content'})
});
const content = await rawResponse.json();
console.log(content);
})();
Can't use ES2017? See #vp_art's answer using promises
The question however is asking for an issue caused by a long since fixed chrome bug.
Original answer follows.
chrome devtools doesn't even show the JSON as part of the request
This is the real issue here, and it's a bug with chrome devtools, fixed in Chrome 46.
That code works fine - it is POSTing the JSON correctly, it just cannot be seen.
I'd expect to see the object I've sent back
that's not working because that is not the correct format for JSfiddle's echo.
The correct code is:
var payload = {
a: 1,
b: 2
};
var data = new FormData();
data.append( "json", JSON.stringify( payload ) );
fetch("/echo/json/",
{
method: "POST",
body: data
})
.then(function(res){ return res.json(); })
.then(function(data){ alert( JSON.stringify( data ) ) })
For endpoints accepting JSON payloads, the original code is correct
I think your issue is jsfiddle can process form-urlencoded request only. But correct way to make json request is pass correct json as a body:
fetch('https://httpbin.org/post', {
method: 'POST',
headers: {
'Accept': 'application/json, text/plain, */*',
'Content-Type': 'application/json'
},
body: JSON.stringify({a: 7, str: 'Some string: &=&'})
}).then(res => res.json())
.then(res => console.log(res));
From search engines, I ended up on this topic for non-json posting data with fetch, so thought I would add this.
For non-json you don't have to use form data. You can simply set the Content-Type header to application/x-www-form-urlencoded and use a string:
fetch('url here', {
method: 'POST',
headers: {'Content-Type':'application/x-www-form-urlencoded'}, // this line is important, if this content-type is not set it wont work
body: 'foo=bar&blah=1'
});
An alternative way to build that body string, rather then typing it out as I did above, is to use libraries. For instance the stringify function from query-string or qs packages. So using this it would look like:
import queryString from 'query-string'; // import the queryString class
fetch('url here', {
method: 'POST',
headers: {'Content-Type':'application/x-www-form-urlencoded'}, // this line is important, if this content-type is not set it wont work
body: queryString.stringify({for:'bar', blah:1}) //use the stringify object of the queryString class
});
After spending some times, reverse engineering jsFiddle, trying to generate payload - there is an effect.
Please take eye (care) on line return response.json(); where response is not a response - it is promise.
var json = {
json: JSON.stringify({
a: 1,
b: 2
}),
delay: 3
};
fetch('/echo/json/', {
method: 'post',
headers: {
'Accept': 'application/json, text/plain, */*',
'Content-Type': 'application/json'
},
body: 'json=' + encodeURIComponent(JSON.stringify(json.json)) + '&delay=' + json.delay
})
.then(function (response) {
return response.json();
})
.then(function (result) {
alert(result);
})
.catch (function (error) {
console.log('Request failed', error);
});

2021 answer: just in case you land here looking for how to make GET and POST Fetch api requests using async/await or promises as compared to axios.
I'm using jsonplaceholder fake API to demonstrate:
Fetch api GET request using async/await:
const asyncGetCall = async () => {
try {
const response = await fetch('https://jsonplaceholder.typicode.com/posts');
const data = await response.json();
// enter you logic when the fetch is successful
console.log(data);
} catch(error) {
// enter your logic for when there is an error (ex. error toast)
console.log(error)
}
}
asyncGetCall()
Fetch api POST request using async/await:
const asyncPostCall = async () => {
try {
const response = await fetch('https://jsonplaceholder.typicode.com/posts', {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({
// your expected POST request payload goes here
title: "My post title",
body: "My post content."
})
});
const data = await response.json();
// enter you logic when the fetch is successful
console.log(data);
} catch(error) {
// enter your logic for when there is an error (ex. error toast)
console.log(error)
}
}
asyncPostCall()
GET request using Promises:
fetch('https://jsonplaceholder.typicode.com/posts')
.then(res => res.json())
.then(data => {
// enter you logic when the fetch is successful
console.log(data)
})
.catch(error => {
// enter your logic for when there is an error (ex. error toast)
console.log(error)
})
POST request using Promises:
fetch('https://jsonplaceholder.typicode.com/posts', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify({
// your expected POST request payload goes here
title: "My post title",
body: "My post content."
})
})
.then(res => res.json())
.then(data => {
// enter you logic when the fetch is successful
console.log(data)
})
.catch(error => {
// enter your logic for when there is an error (ex. error toast)
console.log(error)
})
GET request using Axios:
const axiosGetCall = async () => {
try {
const { data } = await axios.get('https://jsonplaceholder.typicode.com/posts')
// enter you logic when the fetch is successful
console.log(`data: `, data)
} catch (error) {
// enter your logic for when there is an error (ex. error toast)
console.log(`error: `, error)
}
}
axiosGetCall()
POST request using Axios:
const axiosPostCall = async () => {
try {
const { data } = await axios.post('https://jsonplaceholder.typicode.com/posts', {
// your expected POST request payload goes here
title: "My post title",
body: "My post content."
})
// enter you logic when the fetch is successful
console.log(`data: `, data)
} catch (error) {
// enter your logic for when there is an error (ex. error toast)
console.log(`error: `, error)
}
}
axiosPostCall()
I have created a thin wrapper around fetch() with many improvements if you are using a purely json REST API:
// Small library to improve on fetch() usage
const api = function(method, url, data, headers = {}){
return fetch(url, {
method: method.toUpperCase(),
body: JSON.stringify(data), // send it as stringified json
credentials: api.credentials, // to keep the session on the request
headers: Object.assign({}, api.headers, headers) // extend the headers
}).then(res => res.ok ? res.json() : Promise.reject(res));
};
// Defaults that can be globally overwritten
api.credentials = 'include';
api.headers = {
'csrf-token': window.csrf || '', // only if globally set, otherwise ignored
'Accept': 'application/json', // receive json
'Content-Type': 'application/json' // send json
};
// Convenient methods
['get', 'post', 'put', 'delete'].forEach(method => {
api[method] = api.bind(null, method);
});
To use it you have the variable api and 4 methods:
api.get('/todo').then(all => { /* ... */ });
And within an async function:
const all = await api.get('/todo');
// ...
Example with jQuery:
$('.like').on('click', async e => {
const id = 123; // Get it however it is better suited
await api.put(`/like/${id}`, { like: true });
// Whatever:
$(e.target).addClass('active dislike').removeClass('like');
});
Had the same issue - no body was sent from a client to a server.
Adding Content-Type header solved it for me:
var headers = new Headers();
headers.append('Accept', 'application/json'); // This one is enough for GET requests
headers.append('Content-Type', 'application/json'); // This one sends body
return fetch('/some/endpoint', {
method: 'POST',
mode: 'same-origin',
credentials: 'include',
redirect: 'follow',
headers: headers,
body: JSON.stringify({
name: 'John',
surname: 'Doe'
}),
}).then(resp => {
...
}).catch(err => {
...
})
This is related to Content-Type. As you might have noticed from other discussions and answers to this question some people were able to solve it by setting Content-Type: 'application/json'. Unfortunately in my case it didn't work, my POST request was still empty on the server side.
However, if you try with jQuery's $.post() and it's working, the reason is probably because of jQuery using Content-Type: 'x-www-form-urlencoded' instead of application/json.
data = Object.keys(data).map(key => encodeURIComponent(key) + '=' + encodeURIComponent(data[key])).join('&')
fetch('/api/', {
method: 'post',
credentials: "include",
body: data,
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
})
The top answer doesn't work for PHP7, because it has wrong encoding, but I could figure the right encoding out with the other answers. This code also sends authentication cookies, which you probably want when dealing with e.g. PHP forums:
julia = function(juliacode) {
fetch('julia.php', {
method: "POST",
credentials: "include", // send cookies
headers: {
'Accept': 'application/json, text/plain, */*',
//'Content-Type': 'application/json'
"Content-Type": "application/x-www-form-urlencoded; charset=UTF-8" // otherwise $_POST is empty
},
body: "juliacode=" + encodeURIComponent(juliacode)
})
.then(function(response) {
return response.json(); // .text();
})
.then(function(myJson) {
console.log(myJson);
});
}
It might be useful to somebody:
I was having the issue that formdata was not being sent for my request
In my case it was a combination of following headers that were also causing the issue and the wrong Content-Type.
So I was sending these two headers with the request and it wasn't sending the formdata when I removed the headers that worked.
"X-Prototype-Version" : "1.6.1",
"X-Requested-With" : "XMLHttpRequest"
Also as other answers suggest that the Content-Type header needs to be correct.
For my request the correct Content-Type header was:
"Content-Type": "application/x-www-form-urlencoded; charset=UTF-8"
So bottom line if your formdata is not being attached to the Request then it could potentially be your headers. Try bringing your headers to a minimum and then try adding them one by one to see if your problem is resolved.
If your JSON payload contains arrays and nested objects, I would use URLSearchParams and jQuery's param() method.
fetch('/somewhere', {
method: 'POST',
body: new URLSearchParams($.param(payload))
})
To your server, this will look like a standard HTML <form> being POSTed.
You could do it even better with await/async.
The parameters of http request:
const _url = 'https://jsonplaceholder.typicode.com/posts';
let _body = JSON.stringify({
title: 'foo',
body: 'bar',
userId: 1,
});
const _headers = {
'Content-type': 'application/json; charset=UTF-8',
};
const _options = { method: 'POST', headers: _headers, body: _body };
With clean async/await syntax:
const response = await fetch(_url, _options);
if (response.status >= 200 && response.status <= 204) {
let data = await response.json();
console.log(data);
} else {
console.log(`something wrong, the server code: ${response.status}`);
}
With old fashion fetch().then().then():
fetch(_url, _options)
.then((res) => res.json())
.then((json) => console.log(json));
**//POST a request**
const createTodo = async (todo) => {
let options = {
method: "POST",
headers: {
"Content-Type":"application/json",
},
body: JSON.stringify(todo)
}
let p = await fetch("https://jsonplaceholder.typicode.com/posts", options);
let response = await p.json();
return response;
}
**//GET request**
const getTodo = async (id) => {
let response = await fetch('https://jsonplaceholder.typicode.com/posts/' + id);
let r = await response.json();
return r;
}
const mainFunc = async () => {
let todo = {
title: "milan7",
body: "dai7",
userID: 101
}
let todor = await createTodo(todo);
console.log(todor);
console.log(await getTodo(5));
}
mainFunc()
I think that, we don't need parse the JSON object into a string, if the remote server accepts json into they request, just run:
const request = await fetch ('/echo/json', {
headers: {
'Content-type': 'application/json'
},
method: 'POST',
body: { a: 1, b: 2 }
});
Such as the curl request
curl -v -X POST -H 'Content-Type: application/json' -d '#data.json' '/echo/json'
In case to the remote serve not accept a json file as the body, just send a dataForm:
const data = new FormData ();
data.append ('a', 1);
data.append ('b', 2);
const request = await fetch ('/echo/form', {
headers: {
'Content-type': 'application/x-www-form-urlencoded'
},
method: 'POST',
body: data
});
Such as the curl request
curl -v -X POST -H 'Content-type: application/x-www-form-urlencoded' -d '#data.txt' '/echo/form'
You only need to check if response is ok coz the call not returning anything.
var json = {
json: JSON.stringify({
a: 1,
b: 2
}),
delay: 3
};
fetch('/echo/json/', {
method: 'post',
headers: {
'Accept': 'application/json, text/plain, */*',
'Content-Type': 'application/json'
},
body: 'json=' + encodeURIComponent(JSON.stringify(json.json)) + '&delay=' + json.delay
})
.then((response) => {if(response.ok){alert("the call works ok")}})
.catch (function (error) {
console.log('Request failed', error);
});
// extend FormData for direct use of js objects
Object.defineProperties(FormData.prototype, {
load: {
value: function (d) {
for (var v in d) {
this.append(v, typeof d[v] === 'string' ? d[v] : JSON.stringify(d[v]));
}
}
}
})
var F = new FormData;
F.load({A:1,B:2});
fetch('url_target?C=3&D=blabla', {
method: "POST",
body: F
}).then( response_handler )
you can use fill-fetch, which is an extension of fetch. Simply, you can post data as below:
import { fill } from 'fill-fetch';
const fetcher = fill();
fetcher.config.timeout = 3000;
fetcher.config.maxConcurrence = 10;
fetcher.config.baseURL = 'http://www.github.com';
const res = await fetcher.post('/', { a: 1 }, {
headers: {
'bearer': '1234'
}
});
I am trying to create a postHTTP request with some form parameters that are to be set. I am using the axios with node server. I already have a java code implementation of constructing a url as given below:
JAVA CODE:
HttpPost post = new HttpPost(UriBuilder.fromUri (getProperty("authServerUrl"))
.path(TOKEN_ACCESS_PATH).build(getProperty("realm")));
List<NameValuePair> formParams = new ArrayList<NameValuePair>();
formParams.add(new NameValuePair("username",getProperty ("username")));
formParams.add(new NameValuePair("password",getProperty ("password")));
formParams.add(new NameValuePair("client_id, "user-client"));
I am trying to do the same thing in axios.
AXIOS IMPLEMENTATION:
axios.post(authServerUrl +token_access_path,
{
username: 'abcd', //gave the values directly for testing
password: '1235!',
client_id: 'user-client'
}).then(function(response) {
console.log(response); //no output rendered
}
Is the approach to set these form params on the post request correct?
You have to do the following:
var querystring = require('querystring');
//...
axios.post(authServerUrl + token_access_path,
querystring.stringify({
username: 'abcd', //gave the values directly for testing
password: '1235!',
client_id: 'user-client'
}), {
headers: {
"Content-Type": "application/x-www-form-urlencoded"
}
}).then(function(response) {
console.log(response);
});
If your target runtime supports it, Axios is able to accept a URLSearchParams instance which will also set the appropriate Content-type header to application/x-www-form-urlencoded
axios.post(authServerUrl + token_access_path, new URLSearchParams({
username: 'abcd', //gave the values directly for testing
password: '1235!',
client_id: 'user-client'
}))
The same goes for the fetch API
fetch(url, {
method: "POST",
body: new URLSearchParams({
your: "object",
props: "go here"
})
})
Why pull in another library or module to do something so simple with pure vanilla JavaScript? It's really one line of JS to produce the desired data to submit in your POST request.
// es6 example
const params = {
format: 'json',
option: 'value'
};
const data = Object.keys(params)
.map((key) => `${key}=${encodeURIComponent(params[key])}`)
.join('&');
console.log(data);
// => format=json&option=value
const options = {
method: 'POST',
headers: { 'content-type': 'application/x-www-form-urlencoded' },
data,
url: 'https://whatever.com/api',
};
const response = await axios(options); // wrap in async function
console.log(response);
I agree with jhickok, no need to pull in an additional library however their code will not produce a correct result due to the usage of Object.entries, you would expect to see the following:
"format,json=0&option,value=1"
Instead Object.keys should be used.
const obj = {
format: 'json',
option: 'value'
};
const data = Object.keys(obj)
.map((key, index) => `${key}=${encodeURIComponent(obj[key])}`)
.join('&');
console.log(data); // format=json&option=value
Then of course...
const options = {
method: 'POST',
headers: { 'content-type': 'application/x-www-form-urlencoded' },
data,
url: 'https://whatever.com/api',
};
const response = await axios(options);
const body = new URLSearchParams();
body.append('param1', 'param1_value');
...
...
axios.post(url,body)
I have a function that will return a token
var accessToken;
function TestToken(){
return cy.request({
method: 'POST',
url: "https://site/token",
headers: {
'Content-Type': 'application/json',
},
body: {
client_id: '1234',
client_secret: '1234',
audience: 'https://site/api/v1/',
grant_type: 'credentials'
}
}).then(response => {
return new Cypress.Promise((resolve, reject) => {
const rbody = (response.body);
var tokenPattern = "(?i)\"access_token\":\\s*\"([^\"]*)\"";
const authToken = rbody.access_token;
accessToken = authToken
cy.log(accessToken);
resolve(accessToken);
return accessToken;
})
});
I call that function in another cypress command, as I need to use the token in the authorization header
Cypress.Commands.add("ResetPwd", () => {
const authToken = TestToken();
cy.log(authToken);
cy.request({
method: 'POST',
url: "https://site/api/v2/users/1234",
headers: {
'Content-Type': 'application/json',
'authorization': 'Bearer '+authToken,
},
body: {
password: 'Test4321',
connection: 'DB',
}
});
});
When I execute the command, I don't see the token being used. Instead I see "authorization": "Bearer [object Object]" in the request.
In the TestToken funtion, I added cy.log(authToken);, to verify it was correctly grabbing the token. The cypress test failed saying
CypressError: cy.then() failed because you are mixing up async and
sync code.
but I could still see the correct token in the console.
Here is the cypress test I am trying to run
describe('Token Test', function() {
before(() => {
cy.ResetPwd();
})
it('Go to website', function() {
cy.visit('https://site/login')
});
});
functions is synchronous so in moment of call it the result will be equal Promise, promise is object and when you try to stringify object (by + operator) you get [object Object].
After some time promise will be resolved and value in authToken variable will be correct.
To fix it is suggest use Cypress.Promise like in example id cypress docs: https://docs.cypress.io/api/utilities/promise.html#Basic-Promise
I am assuming the TestToken() function is a promise and resolves asynchronously causing the authToken to be [ object Object ]
You could use async/await and the code should work fine.
Add async before the arrow function and use await const authToken = TestToken()
I solved this, after lots of work using cy.task:
cy.request({
method: 'POST',
url: '/where/you/retrieve/your/token',
body: {username: user, password: password},
failOnStatusCode: true
}).then((response) => {
cy.task('setToken', response.body);
});
then:
cy.task('getToken').then((token) => {
cy.request({
method: 'GET',
url: '/your/protected/endpoint/here',
headers: {
authorization: `Bearer ${token}`
},
failOnStatusCode: true
}).then((response) => {
expect(response.something).to.eq(something.else);
});
});
I am trying to create a postHTTP request with some form parameters that are to be set. I am using the axios with node server. I already have a java code implementation of constructing a url as given below:
JAVA CODE:
HttpPost post = new HttpPost(UriBuilder.fromUri (getProperty("authServerUrl"))
.path(TOKEN_ACCESS_PATH).build(getProperty("realm")));
List<NameValuePair> formParams = new ArrayList<NameValuePair>();
formParams.add(new NameValuePair("username",getProperty ("username")));
formParams.add(new NameValuePair("password",getProperty ("password")));
formParams.add(new NameValuePair("client_id, "user-client"));
I am trying to do the same thing in axios.
AXIOS IMPLEMENTATION:
axios.post(authServerUrl +token_access_path,
{
username: 'abcd', //gave the values directly for testing
password: '1235!',
client_id: 'user-client'
}).then(function(response) {
console.log(response); //no output rendered
}
