I have this fetch request below, and variables data_type and data_subtype. I want to pass the value of data_type and data_subtype in the place of :type and :subtype respectively, without actually writing the variable values in there.
fetch('http://localhost:3000/feature/type/:type/subtype/:subtype,{
method: 'GET',
headers: {
'Content-Type': 'application/json'
}
}).then(response => response.text())
.then(data => {
console.log(data);
})
.catch(err => {
console.log(err);
});
You can replace with the variable values in the URL.
eg.
const data_type = 'data Type'
const data_subtype = 'data subtype
fetch(`http://localhost:3000/feature/type/${data_type}/subtype/${data_subtype}`,{
method: 'GET',
headers: {
'Content-Type': 'application/json'
}
}).then(response => response.text())
.then(data => {
console.log(data);
})
.catch(err => {
console.log(err);
});
as expanding the #junkie answer, you should put your url request in string literal so where you can use variables which will conditionaly replace the values without actually writing values in there, so just define and replace them.

I am trying to send the param name in the Cloud Function managed by Firebase using POST method, I've read quite a few documentation, and no matter what I try it always returns undefined. Also is it safe to use this for sensitive data?
Client-Side
fetch(`https://<<APP-NAME>>.cloudfunctions.net/addCardForExistingCustomer`, {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
JSON.stringify(body: {'name': 'Name'})
})
.then(response => response.json())
.then(data => {
console.log(data);
})
.catch(err => console.error(err));
Server-side (Firebase Cloud-Functions)
exports.addCardForExistingCustomer = functions.https.onRequest(async (request, response) => {
let name = await request.body.name
response.json({
response: `${name}`
})
})
This question already has answers here:
How can I pass POST parameters in fetch request? - React Native
(2 answers)
Closed 1 year ago.
I need to add some parameters to this request:
fetch(url_ticket, {
//body: JSON.stringify(data),
//mode: 'no-cors',
param: {
'token': `${token}`,
'id': `${id}`,
'id_secret': `${id_secret}`
},
method: 'POST'
})
.then(response => {
console.log(response.text());
})
.catch(error => {
console.error(error);
});
However, I'm getting an error. I've made that request in Postman an it works, so the problem is obviously in this code. I think the error is in the params parameter; how can I add properly parameters in this request?
I'm literally new to js, i've searched for answers but i can't understand a thing, so posting my real problem has been my last option
Here is the code to send post request with parameter
const data = { username: 'example' };
fetch('https://example.com/profile', {
method: 'POST', // or 'PUT'
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify(data),
})
.then(response => response.json())
.then(data => {
console.log('Success:', data);
})
.catch((error) => {
console.error('Error:', error);
});
For info you can read doc here Using fetch
I think this SO answer is a nice and clean way to do it. Basically, it constructs the URL string with parameters.
fetch(url_ticket + new URLSearchParams({
token: `${token}`,
id: `${id}`,
id_secret: `${id_secret}`
}), {});
You could also construct the parameters in a more manual way, by inserting the variables into a backticked URL string:
let url = `${url_ticket}?token=${token}&id=${id}&id_secret=${id_secret}`;
fetch(url, {...})
Here is my code
let formData = new FormData();
// Update the formData object
formData.append(
"myFile",
this.state.product_picture,
this.state.product_picture.name
);
var options = { content: formData };
const token = JSON.parse(localStorage.getItem('token'));
const requestOptions = {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
},
body: JSON.stringify({
product_name:this.state.product_name,
product_description:this.state.product_description,
product_picture:formData,
category_name:this.state.category_choosen,
})
};
fetch('http://cms.test/api/products/insert_supplier_product?token='+token, requestOptions)
.then(response => response.json())
.then(data => {
this.setState({ product: data.product})
})
.catch(error =>{
console.log("Product creation error", error);
});
I have this fetch api its always giving a 422 response I think what is happening is that its not reading a file as I want to upload a file it all works in postman but when using react it crashes
The body here is the problem
inside the state there are some strings but inside the this.state.product_picture there is a file
Hope someone can help! Thank you!
SOLUTION: Using axios to call the api solved my problem
You cannot send a file in a JSON object in a request( atleast not without Base64 encoding it). Change your code in the following way to send a file with your form.
let formData = new FormData();
// Update the formData object
formData.append(
"myFile",
this.state.product_picture,
this.state.product_picture.name
);
formData.append("product_name",this.state.product_name);
formData.append("product_description",this.state.product_description);
formData.append("category_name",this.state.category_choosen);
var options = { content: formData };
const token = JSON.parse(localStorage.getItem('token'));
const requestOptions = {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'multipart/form-data',
},
body: formData
};
fetch('http://cms.test/api/products/insert_supplier_product?token='+token, requestOptions)
.then(response => response.json())
.then(data => {
this.setState({ product: data.product})
})
.catch(error =>{
console.log("Product creation error", error);
});
$ajax server response:
{"username":"","password":""}
fetch server response:
{"{\"username\":\"\",\"password\":\"\"}":""}
Why aren't they the same? I need the same server response. I'm using PHP+Apache
Here is my code:
import $ from 'jquery';
export function FetchData(type, data){
const serverUrl = 'http://localhost/oms/'+ type + ".php";
return new Promise((resolve, reject) => {
$.ajax({
type: 'POST',
url: serverUrl,
data //body : {username: "username", password:"password"}
})
.done(function(res) {
//console.log(res);
resolve (res);
})
.fail(function(jqXHR, exception){
//alert('server error()');
reject(jqXHR);
});
fetch(serverUrl,{
method: 'POST',
headers: {
Accept: '*/*',
'Content-Type': 'application/x-www-form-urlencoded',
//'Access-Control-Allow-Origin': '*',
//'Access-Control-Allow-Methods': 'POST,GET,OPTIONS,PUT,DELETE',
//'Access-Control-Allow-Headers': 'Content-Type,Accept',
},
body: JSON.stringify(data)
//body : {username: data.username, password: data.password}
})
.then((response) => response.json())
.then((responseJson) => {
resolve(responseJson);
})
.catch((error) => {
reject(error);
});
});
}
The responses are essentially the same just that response from fetch library returns a Stringified JSON.
You need to convert it into actual JS object.
const responseData = JSON.parse(response.json())
This occurs because you're sending the content type application/x-www-form-urlencoded with JSON data you need to change it to application/json like
export const FetchData = (type, data) => {
let serverUrl = 'http://localhost/oms/'+ type + ".php";
let data = {
username: data.username,
password: data.password
};
return new Promise((resolve, reject) => {
fetch(serverUrl, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Accept': 'application/json',
},
credentials: 'include',
body: JSON.stringify(data),
})
.then((response) => response.json())
.then((responseJson) => {
resolve(responseJson)
})
.catch((error) => {
reject(error)
})
})
};
I added credentials it's read-only property of the Request interface indicates whether the user agent should send cookies from the other domain in the case of cross-origin requests. This is similar to XHR’s withCredentials flag
If you want to use something smaller to jQuery you can use Axios It's XMLHttpRequests
If you get some CORS issues this will help you
I'm trying to make a POST request with a GraphQL query, but it's returning the error Must provide query string, even though my request works in PostMan.
Here is how I have it running in PostMan:
And here is the code I'm running in my application:
const url = `http://localhost:3000/graphql`;
return fetch(url, {
method: 'POST',
Accept: 'api_version=2',
'Content-Type': 'application/graphql',
body: `
{
users(name: "Thomas") {
firstName
lastName
}
}
`
})
.then(response => response.json())
.then(data => {
console.log('Here is the data: ', data);
...
});
Any ideas what I'm doing wrong? Is it possible to make it so that the body attribute I'm passing in with the fetch request is formatted as Text like I've specified in the PostMan request's body?
The body is expected to have a query property, containing the query string. Another variable property can be passed as well, to submit GraphQL variables for the query as well.
This should work in your case:
const url = `http://localhost:3000/graphql`;
const query = `
{
users(name: "Thomas") {
firstName
lastName
}
}
`
return fetch(url, {
method: 'POST',
Header: {
'Content-Type': 'application/graphql'
}
body: query
})
.then(response => response.json())
.then(data => {
console.log('Here is the data: ', data);
...
});
This is how to submit GraphQL variables:
const query = `
query movies($first: Int!) {
allMovies(first: $first) {
title
}
}
`
const variables = {
first: 3
}
return fetch('https://api.graph.cool/simple/v1/cixos23120m0n0173veiiwrjr', {
method: 'post',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify({query, variables})
})
.then(response => response.json())
.then(data => {
return data
})
.catch((e) => {
console.log(e)
})
