api request connection issue in nodejs - javascript

I'm trying to make a get request to a web url using basic auth. But it failed with connection issues.
Note: It works when i use 'request' library instead of 'got'
What I'm I missing here ?
const got = require('got');
(async () => {
try {
const res = await got(
{
url: 'https://httpbin.org/anything',
headers: {
Accept: 'application/json'
//Authorization: 'Basic abcjghgh8****'
}
})
console.log('statusCode:', res.statusCode);
console.log('body:', res.body);
} catch (error) {
console.log('error:', error);
}
})();
OUTPUT:
library

When using got(), if you want the body, then you need to use await got(...).json() or await got(...).text() or whatever option is appropriate to your data type. By default, the body has not yet been read (somewhat like the fetch() interface, but easier to use because you can just directly use the .json() method).
const got = require('got');
(async () => {
try {
const body = await got({
url: 'some URL here',
headers: {
Accept: 'application/json',
Authorization: 'Basic abcjghgh8****'
}
}).json(); // add .json() here
console.log('body:', body);
} catch (error) {
console.log('error:', error);
}
})();
And, got().json() resolves directly to the body.
You don't have to check the statusCode yourself because if it isn't a 2xx status, then it will reject the promise automatically.

How to do Spotify Api Post Request using Axios

I'm trying to add a song to the playback queue using this endpoint:
const add = async () => {
try {
const url = `https://api.spotify.com/v1/me/player/queue?uri=${songUrl}&device_id=${deviceId}`
await axios.patch(url, {
headers: {
Authorization: `Bearer ${to}`
},
})
} catch (error) {
console.log(error);
}
}
I'm getting a status 401 error with a message that says no token provided. But when I console.log the token it shows up.
I haven't worked with the Spotify API yet, however, according to their docs, you need to send a POST request, not a PATCH, which is what you used.
Use axios.post() instead of axios.patch():
const add = async (songUrl, deviceId, token) => {
try {
const url = `https://api.spotify.com/v1/me/player/queue?uri=${songUrl}&device_id=${deviceId}`;
await axios.post(url, {
headers: {
Authorization: `Bearer ${token}`,
},
});
} catch (error) {
console.log(error);
}
};
The second param of your post request should be body and the third param should be headers. Also, you haven't added all the headers as mentioned in the documentation.
headers: {
Accept: 'application/json',
Authorization: 'Bearer ' + newAccessToken,
'Content-Type': 'application/json',
}
Get your access token from here: https://developer.spotify.com/console/post-queue/
If it still doesn't work try the curl method as mentioned in their docs and if it works, switch it to axios.
I had the exact same issue as you, what I realised was I was passing the header as data rather than as config. This code below should work for you as it works for me.
const add = async () => {
try {
const url = `https://api.spotify.com/v1/me/player/queue?uri=${songUrl}&device_id=${deviceId}`
await axios.post(url, null,{
headers: {
Authorization: `Bearer ${to}`
},
})
} catch (error) {
console.log(error);
}
}

Refactor from fetch to await that can yield same result

So I moved over a non-reusable fetch request code snippet to my API:
let response = await fetch(visitURL, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer ' + userJWT
},
body: JSON.stringify(endingVisit)
});
if (response.ok) {
let {visitId, createdAt} = await response.json();
const viewVisitDto = new ViewVisitDto(`${visitId}${createdAt}${visitorId}${doctorId}${oldPatientId}`);
return viewVisitDto;
} else {
throw new Error("deactivated!")
}
I was able to get this far:
axios.post(visitURL, {
headers,
body: JSON.stringify(visit)
}).then((response) => {
console.log(response);
}).catch((error) => {
console.log(error);
})
But does not exactly give me the visitId and createdAt from the response and I cannot use a response.ok nor a response.json(). Essentially I need to pull out that visitId and createdAt that should be coming back in the response.
I also tried just using node-fetch library, but although in VS code it seems to accept it, TypeScript is not happy with it even when I do install #types/node-fetch and even when I create a type definition file for it, my API just doesn't like it.
Guessing what you are after is
// don't know axios, but if it returns a promise await it
const dto = await axios.post(visitURL, {
headers,
body: JSON.stringify(visit)
}).then((response) => {
// parse response
return {resonse.visitId, resonse.createdAt}
}).then(({visitId, createdAt}) => {
// form dto (where are other vals)?
return new ViewVisitDto(`${visitId}${createdAt}${visitorId}${doctorId}${oldPatientId}`);
}).catch((error) => {
console.log(error);
})
However - you don't mention where doctorId and oldPatientId come from... You try providing more info, including output of the console.log's and the surrounding code

Making a request with Axios inside Promise.all

I have a script that updates the content of an API. There are several, so the only way is to call repeatedly to the endpoint to get the content of each API. When I am already inside the promise all, and I have the array of promises, what I do is iterating and updating the content that I have obtained.
Although the code seems to be working with an API only, I don't know what is the ideal way to make requests with Axios or fetch inside a promise.all or if just making the request is enough. Think that if for example there are 500 sequences, it will iterate through them and update their content.
The code is:
let promises = [];
data.sequences.forEach((sequence) => {
promises.push(axios.get(
`https://${conf.server.hostname}:${conf.server.port}/resource/${conf.version}/${sequence}`, {
headers: {
'Content-Type': 'application/json',
Authorization: 'Bearer bbbbbbb'
}
}
))
});
Promise.all(promises).
then((sequences) => {
//for each sequence to update
for (let i = 0; i < sequences.length; i++) {
let indexPromise = sequences[i];
axios.put(
`https://${conf.server.hostname}:${conf.server.port}/resource/${conf.version}/${sequenceName}`,
indexPromise.data, {
headers: {
'Content-Type': 'application/json'
}
}
).then((response) => {
logger.debug(`Updating content : ${sequenceName}`);
}).catch((err) => {
logger.error(`Error updating content`, err);
})
}
return callback(null, data)
}).catch((err) => {
logger.error(`Error getting content:`, err);
});
I would suggest this structure that makes the .get() and .put() into a combined operation and then runs Promise.all() once on the combined operations:
function someFunction() {
const corePath = `https://${conf.server.hostname}:${conf.server.port}/resource/${conf.version}`;
// return a promise that indicates when we're all done or had an error
return Promise.all(data.sequences.map(sequence => {
return axios.get(`${corePath}/${sequence}`, {
headers: {
'Content-Type': 'application/json',
Authorization: 'Bearer bbbbbbb'
}
}).then(data => {
return axios.put(`${corePath}/${sequenceName}`, data, {
headers: {
'Content-Type': 'application/json'
}
});
}).then(() => {
logger.debug(`Updating content : ${sequenceName}`);
}).catch(err => {
logger.error(`Error updating content`, err);
throw err;
});
});
}
Other notes:
Don't mix plain callbacks and promises. If you need to communicate back to some other code when this is done or has an error, then return your promise - don't use a callback.
You don't show where sequenceName comes from. Your debug output makes it seem like it's something that varies by request, but it isn't defined anywhere in the code in your question.
If you want the promise this is returning resolve with some data, then return that value from the final .then(). Your question shows you calling a callback and passing it data, but doesn't show where that comes from.

catching error body using axios post

I am sending a status code 422 from my backend code with response body which contains the description of the error. I am using axios post as below to post a request:
post: function(url, reqBody) {
const request = axios({
baseURL: config.apiUrl,
url: url,
headers: {
'Content-Type': 'application/json',
'Authorization': sessionStorage.getItem('token')
},
method: 'POST',
data: reqBody,
responseType: 'json'
});
return request
.then((res) => {
return res;
})
.catch((error) => {
console.log(error);
return error;
})
}
The problem is when backend is returning error code 422, the error object I am catching has no information about response body. Is there any way I can retrieve the error text?
I had this same issue and the answer (as per Axios >= 0.13) is to specifically check error.response.data:
axios({
...
}).then((response) => {
....
}).catch((error) => {
if( error.response ){
console.log(error.response.data); // => the response payload
}
});
See here for more details.
The "body" of an AXIOS error response depends from the type of response the request had.
If you would like full details about this issue you can see this blogpost: How to catch the body of an error in AXIOS.
In summary AXIOS will return 3 different body depending from the error:
Wrong request, we have actually done something wrong in our request (missing argument, bad format), that is has not actually been sent. When this happen, we can access the information using error.message.
axios.get('wrongSetup')
.then((response) => {})
.catch((error) => {
console.log(error.message);
})
Bad Network request: This happen when the server we are trying to reach does not respond at all. This can either be due to the server being down, or the URL being wrong.
In this case, we can access the information of the request using error.request.
axios.get('network error')
.then((response) => {})
.catch((error) => {
console.log(error.request );
});
Error status: This is the most common of the request. This can happen with any request that returns with a status that is different than 200. It can be unauthorised, not found, internal error and more. When this error happen, we are able to grasp the information of the request by accessing the parameter specified in the snippets below. For the data (as asked above) we need to access the error.response.data.
axios.get('errorStatus')
.then((response) => {})
.catch((error) => {
console.log(error.response.data);
console.log(error.response.status);
console.log(error.response.headers);
})
For those using await/async and Typescript
try {
const response = await axios.post(url, body)
} catch (error) {
console.log(error.response.data);
}
For react native it just worked for me
api.METHOD('endPonit', body)
.then(response => {
//...
})
.catch (error => {
const errorMessage = JSON.parse(error.request.response)
console.log(errorMessage.message)
})
We can check error.response.data as #JoeTidee said. But in cases response payload is blob type? You can get error response body with the below code.
axios({
...
}).then((response) => {
....
}).catch(async (error) => {
const response = error.response
if(typeof response.data.text === function){
console.log(await response.data.text()); // => the response payload
} else {
console.log(response.data)
}
});
I am returning a string from backend but expecting a json as response type. So I need to return an object instead of string for axios to process it properly.
In my case I wanted to retrieve a response 404 error message (body).
I got body with error.response.data but I couldn't display it because the type was ArrayBuffer.
Solution:
axios.get(url, { responseType: 'arraybuffer' }).then(
response => {...},
error => {
const decoder = new TextDecoder()
console.log(decoder.decode(error.response.data))
}
)

Handling non JSON response with a Body.json() promise

I'm trying to create a scheme to intercept and handle requests from an API middleware, however, for whatever reason I'm unable to properly handle non JSON responses from my API endpoint. The following snippet works just fine for server responses formatted in JSON however say an user has an invalid token, the server returns a simple Unauthorized Access response that I'm unable to handle even though I am supplying an error callback to the json() promise. The Unauthorized Access response message is lost in the following scheme.
const callAPI = () => { fetch('http://127.0.0.1:5000/auth/', {
method: 'GET',
headers: {
'credentials': 'include',
'Accept': 'application/json',
'Content-Type': 'application/json',
'Authorization': 'Basic bXlKaGJHY2lPaUpJVXpJMU5pSXNJbVY0Y0NJNk1UUTVPRE15TVRNeU5pd2lhV0YwSWpveE5EazRNak0wT1RJMmZRLmV5SnBaQ0k2TVgwLllFdWdKNF9YM0NlWlcyR2l0SGtOZGdTNkpsRDhyRE9vZ2lkNGVvaVhiMEU6'
}
});
};
return callAPI().then(res => {
return res.json().then(responseJSON => {
if(responseJSON.status === 200){
return dispatch({
type: type[1],
data: responseJSON,
message: success
});
} else if(responseJSON.status === 401) {
return dispatch({
type: type[2],
message: responseJSON.message
});
}
return Promise.resolve(json);
}, (err) => {
console.log(err.toString(), ' an error occured');
});
}, err => {
console.log('An error occured. Please try again.');
});
Try using text method of Body: res.text().
Try to wrap your response handling code in a try...catch block like this:
return callAPI().then(res => {
try {
return res.json().then(responseJSON => {
[...]
catch(e) {
console.error(e);
}
});
Body.json() throws when the body is actually not JSON. Therefore, you should check if the body contains JSON before you call json() on it. See https://developer.mozilla.org/en-US/docs/Web/API/Response.
