I try to get a list from server based on some filters. But vuejs not waiting server response.
<input type="text" name="oooo" #input="getUsers">
...
methods: {
getUsers: async function () {
const response = await axios.post('/skills', { {"key": "toto"} } );
this.list = response.data;
console.log(response);
}
}
...
I get results in server logs. but vuejs is returning empty array.
What is wrong with my ajax request?
thanks
You are using axios.post, instead of axios.get

I have an issue where we're using apollo client and specifically the useMutation react hook to perform mutation calls to our GraphQL Server.
At certain times, the server may return a 401 unauthorized response - at which point, we can make a call to special endpoint which re-authenticates the client and refreshes the cookie/token whatever.
I want to be able to re-run the same mutation again once the client is re-authenticated. So basically I would like to know if it is possible to do the following:
useMutation --> Receive 401 Unauthorized --> call to refresh token --> rerun same initial mutation
This is how our useMutation looks like:
const [mutationFunction, { data, ...rest }] = useMutation(query, {
onError(_err: any) {
const networkError = error?.networkError as any;
if (networkError?.statusCode === 401 && !refreshFailed) {
// eslint-disable-next-line prefer-destructuring
loading = true;
error = undefined;
fetch('/authentication/refresh', {
method: 'POST',
headers: { 'Content-Type': 'application/json' }
})
.then(response => response.json())
.then(token => {
localStorage.setItem(jwtLocalStorageKey, token);
// re fetch here
})
.catch(() => {
refreshFailed = true;
});
} else {
showAlert(_err.message, 'error');
}
}
});
and this is how we call it currently:
const {
mutationFunction: updateTournamentUserMutation,
loading: updateTournamentUserLoading,
error: updateTournamentUserError,
data: updateTournamentUserData
} = useMutationHook(gqlUpdateTournamentUser);
updateTournamentUserMutation({ variables: { input } });
Because we're using hooks and the way we're using it above, I'm not entirely sure how we can save or reuse the same data that is initially sent in the first mutation (that is the mutation parameters)
Is it possible to do so using the current way we're doing it?
I am using vue js as frontend with laravel. I am using laravel passport for auth, now i wants to show some error message once received 401 unauthentic error message that mostly occurs when my token expired. so to do this i am using axios interceptors my code is like
axios.interceptors.response.use(function (response) {
return response
}, function (error) {
// const { config, response: { status } } = error
const { config, response } = error
const originalRequest = config
if (response && response.status === 401) {
//notication or redirection
this.$vs.notify({
title: 'Error',
text: response.data['message'],
iconPack: 'feather',
icon: 'icon-check-circle',
color: 'danger'
})
}
return Promise.reject(error)
})
Now Question is that where i put this code in vue js so that it call after every request & so an error message shown & redirect to login once get 401 unauthorized..
Any Suggestion from anyone.
Thanks in advance!!
app.js or add them to separate file and include in app.js. There is post about this https://medium.com/#yaob/how-to-globally-use-axios-instance-and-interceptors-e28f351bb794
I'm using an express api (my back-end) and an angular app (my front-end).
One express js end point (let's call it '/foo') is processing a lot of files,
i send data using res.write() after each treatment so the http response body is update.
I would like to get this update on my angular app.
I was using ajax in a previous version and it worked fine with ajax call :
xhrFields: {
// Getting on progress streaming response
onprogress: function(e)
{
var progressResponse;
var response = e.currentTarget.response;
if(lastResponseLength === false)
{
progressResponse = response;
lastResponseLength = response.length;
}
else
{
progressResponse = response.substring(lastResponseLength);
lastResponseLength = response.length;
}
actualResponse += progressResponse
}
Unfortunatly i found nothing to get partial http body. I tried to use 'reportProgress' Parameter but it's not working.
For some more context my front-end angular code:
service.ts :
setHolidaysDirectory(holidaysKey: string, path: string): Observable<Object>{
const setHolidayDirectoryStreamHttpRequest =
new HttpRequest('POST', 'http://localhost:8089/holidays/pictures/edit', { 'key': holidaysKey,
'path': path
}, {headers: this._httpHeaders, reportProgress: true, responseType: 'text'});
// pipe stream answer
return this._http.request(setHolidayDirectoryStreamHttpRequest);
}
and my component just call the service and subscribe :
this._holidaysService
.setHolidaysDirectory(key, finalHolidaysForm.path)
.subscribe((stream) => {
console.log('new answer');
console.log(stream);
}, error => console.log(error));
But unfortunatly i got empty answer and all the http body is recovered after res.end() (server side)
Can anyone help pls !
Thank a lot !
I am using supertest and mocha to test a nodejs application. One of the things users can do is to submit a very simple form, which is picked up by the node server and parsed using formidable.
Here is the mocha test code:
var should = require('should'),
express = require('express'),
app = require('../app.js'),
request = require('supertest'),
csrfToken,
sessionId,
cookies = [];
describe('Post Handler', function(){
it('Uploads new post', function(done){
var req = request(app).post('/post?_csrf=' + csrfToken);
req.cookies = cookies;
req
.type('form')
.send({fieldTitle: 'autopost'})
.send({fieldContent: 'autocontent'})
.send({contentType: 'image/png'})
.send({blobId: 'icon_23943.png'})
.expect(200)
.end(function(error, res){
console.log('here');
done();
});
});
csrfToken retrieves a csrf token from the server, since I am using the csurf module and every POST method requires a csrf token. cookies stores the session cookie that is provided by the node server so I can persist the session between requests.
The form is processed by the following code:
//Takes HTTP form posted by client and creates a new post in the Db
exports.postPostUpload = function (req, res) {
var form = new formidable.IncomingForm();
form.parse(req, function (err, fields, files) {
console.log(err);
if (err) res.redirect(303, '/error');
else {
var new_post = new post_model.Post().createNewPost(fields);
new_post.setUserId(req.session.passport.user.userId);
new_post.uploadPostToDb(function (error, result) {
if (error) return res.status(500).end();
else {
if (new_post.media.contentType.indexOf('video') !== -1) {
addMessageToEncodingQueue(new_post, function (error, result, response) {
if (error) {
errorHelper.reportError({
stack: new Error().stack,
error: error
});
res.status(500).end();
}
else res.status(200).send(new_post.cuid);
});
}
else return res.status(200).send(new_post.cuid);
}
});
}
});
}
My current problem is, that once the form handler executes the line form.parse(req, function (err, fields, files) {, nothing happens. Formidable does not return error, it just does not return anything. Consequently, the mocha test never receives a reply from the server, and eventually the socket hangs and the test crashes. Needless to say, the form is successfully submit if you do it manually via the website.
There must be an error in the way supertest/mocha are executing this test, but I have not been able to find it. Any pointers are highly appreciated.
I am using NodeJS. One of my function (lets call it funcOne) receives some input which I pass to another function (lets call it funcTwo) which produces some output.
Before I pass the input to funcTwo I need to make an Ajax call to an endpoint passing the input and then I must pass the output produced by the AJAX call to funcTwo. funcTwo should be called only when the AJAX call is successful.
How can I achieve this in NodeJS. I wonder if Q Library can be utilized in this case
Using request
function funcOne(input) {
var request = require('request');
request.post(someUrl, {json: true, body: input}, function(err, res, body) {
if (!err && res.statusCode === 200) {
funcTwo(body, function(err, output) {
console.log(err, output);
});
}
});
}
function funcTwo(input, callback) {
// process input
callback(null, input);
}
Edit: Since request is now deprecated you can find alternatives here
Since request is deprecated. I recommend working with axios.
npm install axios#0.16.2
const axios = require('axios');
axios.get('https://api.nasa.gov/planetary/apod?api_key=DEMO_KEY')
.then(response => {
console.log(response.data.url);
console.log(response.data.explanation);
})
.catch(error => {
console.log(error);
});
Using the standard http library to make requests will require more effort to parse/get data. For someone who was used to making AJAX request purely in Java/JavaScript I found axios to be easy to pick up.
