I am trying to send a request using axios post with basic authorization. It is working fine with postman but not working when I try to send via code.
axios.post(`my-url`, {
headers: {
'Content-Type': 'application/json',
'Authorization': 'Basic **KEY_HERE**',
},
data: {
'id': 'event_order',
'date': '2021-09-09'
}
}).then(async (response) => {
console.log(response.data)
})
It is returning 401 Unauthorized. But, it works as excepted when I call it via Postman:

Did you add your domain to whitelist in your cors module? If not:
app.use(cors({ origin: "PROTOCOL://DOMAIN:PORT", credentials: true }));
edit: Ok, sorry, I was confused and thought you were sending a frontend axios post request to your own NodeJS server. If possible, could you be more precise. But try passing in your headers/auth as the third argument-- since you're passing in everything in the second argument, the API is not parsing out your headers since its part of the data parameter.
const data = {
'id': 'event_order',
'date': '2021-09-09'
}
axios.post(`my-url`, data, {
headers: {'Content-Type': 'application/json'},
auth: {
username: "YOUR_USERNAME",
password: "YOUR_PASS"
}
})
.then(async (response) => {
console.log(response.data)
})
Also try and post the network errors, if you can.

When I try to send some input from my form to my react backend, it prompts the CORS error even if I have CORS used in the server.js file. I have attached and image from the front-end and from the back-end
handleSubmit from my react app
handleSubmit = (event) => {
event.preventDefault();
console.log('Registration form was submitted');
console.log(this.state.fullname +' '+ this.state.age+' '+ this.state.adress)
fetch('https://localhost:4000/regUser', {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify({
name: this.state.fullname,
age: this.state.age,
adress: this.state.adress
})
}).then( res => res.json())
.then(data => console.log(data))
}
This the CORS error is misleading in some cases.
And your case is one of those cases.
You are calling a post request on route /regUser but you are listening for get request on your server :
Change your server code to :
app.post("/regUser",(req,res)=>{
let data=req.body;
return res.send(data);
}
Note : As you are accessing req.body I have assumed that you want to use post in other cases just make sure you are sending and listening for same kind of request.
And as pointed in comments your server is not configured for https so use http instead.
I'm using axios to perform get and post requests to an external api,
i have finally succeed to achieve get request (problem with the ssl certificate, i avoid it by adding this :
httpsAgent: new https.Agent({ rejectUnauthorized: false }),
now i would like to post the api,
to get the request working in postman, i put in
headers content-type : application/json
and in the body : {}
like here
when trying with a google chrome extention, to make it work, i put nothing in the headers but in params, i select customer : application/json and i put inside this {} instead of the default choice which is x-www-form-urlencoded;charset=UTF-8
chrome extention
in my javascript app i tried this
var url = https://10.11.31.100:9440/api/nutanix/v3/images/list;
axios({
method:'post',
httpsAgent: new https.Agent({ rejectUnauthorized: false }),
url,
auth: {
username: '******',
password: '********'
},
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
'X-Requested-With': 'XMLHttpRequest'
},
params: {},
data: {}
})
.then(function (response) {
res.send(JSON.stringify(response.data));
console.log(response);
})
.catch(function (error) {
console.log(error);
});
I get this problem :
TypeError : UTF-8 is not a function
Specifically with regards to the Nutanix v3 REST API - this is probably because the POST request above doesn't have an appropriate JSON payload i.e. the "data" parameter is empty.
When sending Nutanix v3 API POST requests, specifically to "list" entities, you'll need to specify the "kind" of entity being listed. In your example, the JSON payload below will work.
{"kind":"image"}
See here: https://nutanix.dev/reference/prism_central/v3/api/images/postimageslist
HTH. :)
I'm trying to get/read the response from a POST request made in Angular 7, if I set the API to return "text" everything is OK, but when i make the response a JSON the response body on Angular is null.
If I try the API on Postman I get full response JSON body.
I tried changing response method on Express API (from the simple res.json() to the "old" way of declaring Content-Type and sending it with res.end()), nothing changed.
The response code I'm using on backend:
res.status(200).json({
success: true,
token: token
})
What I also tried:
res.writeHead(200, { 'Content-Type': 'application/json' })
var json = JSON.stringify({
success: true,
token: token
})
res.end(json)
The service I'm using on Angular:
login(username: string, password: string): Observable<any> {
let body = {username: username, password: password};
let headers = new HttpHeaders();
headers.set('Content-Type', 'application/json');
return this.http.post(this.baseUrl + "/login/sign-in", body, {headers: headers, responseType: 'json', observe: 'response'});
}
The call to that service:
this.api.login("admin", "password").subscribe(result => {
console.log(result);
})
On Postman I get this result:
On Angular I get this (JSON):
On Angular I get this (TEXT):
Edit:
If I add anything before the JSON on the Express app, the body is no more null:
res.writeHead(200, { 'Content-Type': 'application/json' })
var json = JSON.stringify({
success: true,
token: token
})
res.end('some_char' + json)
The result (of course the response goes in error):
Edit 2:
I'm also trying (with no luck) with this simple version of the endpoint:
const express = require('express')
const app = express()
app.post('/login/sign-in', (req, res) => res.json({ value: 1 }))
app.listen(3000, () => {
console.log('App running on port 3000.')
})
Solution:
It was all a CORS problem, I added this to the backend and everything is working fine:
app.use(cors())
Spent a few minutes trying to find out why the body would be empty,
In my case, I had "mode":"no-cors" set in my fetch() options, therefore the returned value from the server would appear as "opaque"
redux fetch body is not use with no cors mode
I hope this can help !
Authorization for Client Credentials Flow
Hi I have read other Questions or not working properly the current response is 400 (Bad Request) what I had
The following is my code (Authorization has converted Base64)
const testAuth = () => {
return () => {
Axios({
url: 'https://accounts.spotify.com/api/token',
method: 'post',
params: {
grant_type: 'client_credentials'
},
headers: {
'Authorization': 'Basic MWM3NGFkOGQyNDgzNDI0Y2E4NGVmYWRlNzI1MzI5YzE6MDBmMGFmNDE1ZTZhNDgxOThiOWRlYzFmNmE2NTk5NDQ=',
'Content-Type': 'application/x-www-form-urlencoded'
},
}).then((respond) => {
console.log(respond);
}).catch((error) => {
console.log(error);
});
};
But things that are working with returned tokens as well as using spotify wep api normally by using Postman to send out the same content . Is my code uncorrent or is there any problem? (Authorization in Postman is the same as above)
Thank everyone, I just realized is an error of cors. However, there are many ways for trying still can't solve the 400.
For eaxmple: Chrome extension access-control-expose-headers

I am using React and node.js, and I've used react's fetch to POST some Login credentials to my restAPI in order to receive a webtoken...
fetch('http://localhost:8080/api/login', {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify({
username: this.state.username_login,
password: this.state.password_login
})
})
.then((response) => response.json())
.then((responseJson) => {
console.log(responseJson); //this is the object containing the token
})
.catch(function(error) {
console.log("request failed");
})
}
so responseJson is the the object containing my web token. The request was successful and now I've passed it to the client. Now, I am thinking of saving it to a cookie.
How can I send this to the server? Should I make a POST request? If so how do I do that once the JSON object is received? If there is a better way, I would like to know.
Cookies are automatically passed along any HTTP request made with fetch
