Next JS API Routes add query on Client side

I am fetching IGDB api on server because I need to go through CORS. I am using async await connected to client side. Everything works fine but I need to pass query like '/?fields=cover.*,name;limit=50;' to https://api.igdb.com/v4/games from client side, not from server. When I am adding a query to client side, it's still showing the query only from server. How I can pass this query from client side? This is my code:
api/example.js
import Cors from "cors";
import initMiddleware from "../../components/init-middleware";
const cors = initMiddleware(
Cors({
methods: ['GET', 'POST', 'OPTIONS'],
})
)
const settings = {
method: 'POST',
headers: {
'Accept': 'application/json',
'Client-ID': 'my_client-id',
'Authorization': 'Bearer my_authorization',
},
}
const remoteServerUrl = 'https://api.igdb.com/v4/games'
export default async function handler(req, res) {
await cors(req, res)
const response = await fetch(remoteServerUrl, settings);
const data = await response.json()
res.json(data)
}
client side
const settings = {
method: 'POST',
headers: {
'Accept': 'application/json',
'Client-ID': 'my_client-id',
'Authorization': 'Bearer my_authorization',
},
const fetchData = async () => {
let query = '/api/example/'
const response = await fetch(query + HERE I WANT TO ADD QUERY, settings);
const data = await response.json();
}
Edit:
Status Code: 308 Permanent Redirect
initMiddleware
// Helper method to wait for a middleware to execute before continuing
// And to throw an error when an error happens in a middleware
export default function initMiddleware(middleware) {
return (req, res) =>
new Promise((resolve, reject) => {
middleware(req, res, (result) => {
if (result instanceof Error) {
return reject(result)
}
return resolve(result)
})
})
}

Response <403> Despite Correct Authorization in nodejs

I am trying to send a post request to a URL, I did this in python with the following code and it worked like a charm and I got a [Response <200>], but since I needed to use this in a website, I switched over to JS and tried to recreate the same functionality, but for some reason I'm getting a [Response <403>] even tho all my auth tokens and headers and everything is same as the python code.
Python Code -
url = "https://discord.com/api/v8/channels/801784356711956522/messages"
auth = ""
headers = {"Authorization": auth,
'Content-Type': 'application/json', 'referer': "https://discord.com/channels/801784356217421874/801784356711956522"}
payload = {'content': 'Test' , 'nounce': 802056256326991872, 'tts': False}
response = requests.post(url, data=json.dumps(payload), headers=headers)
print(response)
JavaScript Code -
onst url = "https://discord.com/api/v8/channels/801784356711956522/messages"
const auth = ""
const headers = {"Authorization": auth,
'Content-Type': 'application/json',
'referer': "https://discord.com/channels/801784356217421874/801784356711956522"}
const options = {
headers : headers,
}
const data = JSON.stringify({'content':"Test" , 'nounce': 802056256326991872, 'tts': false})
process.env["NODE_TLS_REJECT_UNAUTHORIZED"] = 0;
const req = https.request(options, (res) => {
console.log(`statusCode: ${res.statusCode}`)
res.on('data', (d) => {
process.stdout.write(d)
})
})
req.on('error', (error) => {
console.error(error)
})
req.write(data)
req.end()

In your python code, you made a POST request but in JavaScript code, you made a GET request because you did not provide the method option.
It is specified in https.request options documentation:
method A string specifying the HTTP request method. Default:
'GET'.
To make POST request modify like this
const options = {
headers : headers,
method: "POST"
}
Also, you need to add URL since you did not provide hostname and path in the options.
const req = https.request(url, options, (res) => {
// ...
})

const querystring = require('querystring');
const https = require('https');
var postData = querystring.stringify({
'msg' : 'Hello World!'
});
var options = {
hostname: 'domain.com',
port: 443,
path: '/yow-path',
method: 'POST',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
'Content-Length': postData.length
}
};
var req = https.request(options, (res) => {
console.log('statusCode:', res.statusCode);
console.log('headers:', res.headers);
res.on('data', (d) => {
process.stdout.write(d);
});
});
req.on('error', (e) => {
console.error(e);
});
req.write(postData);
req.end();

Can not download file while sending request from one node.js server to another

I am facing some issue while downloading file using node.js. I have scenario like my angular component is sending the file request. in my first node server I am doing the token validation and then redirecting to another node server where actually the execution happens. I am explaining my code below.
service.ts:
submitAndDownloadFile(formdata : any ){
const token = localStorage.getItem('token')
let headers = new HttpHeaders({
Authorization: 'Basic ' + token
})
const cecID = localStorage.getItem('cec');
const AppUrl = `${environment.nodeJsBaseUrl}:${environment.hostingNodeJsContainerPort}/convert-test-cases/${cecID}`;
return this.httpClient.post(AppUrl, formdata, { responseType: 'blob', observe : 'response', headers : headers});
}
Here I am sending the request to my first node.js server which code has given below.
app.js(first:port-8000):
router.post('/convert-test-cases/:id', middleware.auth, (req, res) => {
try{
let postRequestOptions = {
url: '',
method: 'POST',
json: true,
headers: {},
body: {},
};
postRequestOptions.url = 'http:localhost:9000/convert-test-cases';
postRequestOptions.headers = {
'Content-Type': 'application/json',
};
postRequestOptions.body = req.body;
request(postRequestOptions, async (error, response, pathList) => {
if(error) {
console.log('error', error);
}else{
res.send(pathList);
}
})
}catch(e){
responseObj = {
status: 'error',
msg: 'Error occurred while processing your request',
body: null
}
return res.send(responseObj);
}
})
Here I am doing the token validation using middleware.auth and sending same request to another node.js file which code is explained below.
app.js:(second-port-9000):
router.post('/convert-test-cases', async (req, res) => {
try{
let response = await ctcCtrl.convertTestCase(req.body, req.files);
if(response.status == 'success'){
res.set('Access-Control-Expose-Headers','*, Content-Disposition');
return res.download(response.fileName,response.fileName);
}else{
return res.send(response);
}
}catch(e){
responseObj = {
status: 'error',
msg: 'Error occurred while processing your request',
body: null
}
return res.send(responseObj);
}
})
Here only I am doing some execution and downloading the file. If I am connecting angular to node-9000 its working fine but my requirement is first I have to connect to port-8000 to some token validation and after that I have to send same req.body and re.file to app.js which is running in 9000 using request module. As per my code its not working at all.

difference between api call and on postman

I was using Azure Speech rest api. And i tried it on post man with a .wav file and it successfully return the result. However, when i call api from my node.js code. It always return Unsupported Audio Format even though i give the same audio file. Can anyone tell me what's the difference of them? Or what did Postman do to make it work?
Below is how i call speech api by node.js.
'use strict';
const request = require('request');
const subscriptionKey = 'MYSUBSCRIPTIONKEY';
const uriBase = 'https://westus.stt.speech.microsoft.com/speech/recognition/conversation/cognitiveservices/v1?language=en-US';
const options = {
uri: uriBase,
body: 'speech.wav',
headers: {
'Content-Type': 'application/json',
'Ocp-Apim-Subscription-Key' : subscriptionKey,
'Transfer-Encoding': 'chunked',
'Expect': '100-continue',
'Content-type':'audio/wav; codec=audio/pcm; samplerate=16000'
}
};
request.post(options, (error, response, body) => {
if (error) {
console.log('Error: ', error);
return;
}
let jsonResponse = JSON.stringify(JSON.parse(body), null, ' ');
console.log('JSON Response\n');
console.log(jsonResponse);
});

You can try this
fs.readFile('/path/to/my/audiofile.wav', function (err, data) {
if (err) throw err;
var options = {
host: 'https://westus.stt.speech.microsoft.com/speech/recognition/conversation/cognitiveservices/v1?language=en-US',
method: 'POST',
headers: { 'Content-Type': 'audio/wav' }
};
var req = http.request(options, function(res) {
// Handle a successful response here...
});
req.on('error', function(e) {
// Handle an error response here...
});
// Write the audio data in the request body.
req.write(data);
req.end();
});

Node request how to handle sessions

I'm using node.JS with request module.
My problem is, I need to authenticate the user on every request because the session is destroyed outside of the .then((response) => {}) block.
How is it possible to save the created session in a class for later use?
I tried out everything without success.
Here is a not working code snippet
login() {
const getLoginUrl = 'https://www.demourl.com/'
const postLoginUrl = 'https://www.demourl.com/account/login/'
rp({
url: getLoginUrl,
jar: this.cookieJar,
method: 'GET'
})
.then((body) => {
var csrftoken = this.cookieJar.getCookies(getLoginUrl)[1].toString().split('=')[1].split(';')[0];
var args = {
url: postLoginUrl,
json: true,
method: 'POST',
data: {
username: this.username,
password: this.password
},
headers: {
'method': 'POST',
'path': '/account/login/',
'cookie': 'csrftoken=' + csrftoken,
},
jar: this.cookieJar,
resolveWithFullResponse: true
}
rp(args)
.then((response) => {
//Here is a valid session
//But how can I use this session in different functions?
console.log('Post demourl.com/account/login success');
})
.catch((error) => {
console.log('Post demourl.com/account/login error: ', error);
});
})
.catch((error) => {
console.log('Get demourl.com error: ', error);
});
}

you should use this function as a middleware and then attach what ever you want to attach in to your req
try in you main script do
'use strict'
const express = require('express');
const login = require('./login');
const app = express()
app.use(login);// use this if you want all your routes to check login or put it in a specific route
app.get('/', (req,res)=>{
//this route is only for loged in users
});
const server = http.createServer(app).listen(process.env.PORT);
module.exports = app;
and in your login script
const login = (req, res, next) => {
const getLoginUrl = 'https://www.demourl.com/'
const postLoginUrl = 'https://www.demourl.com/account/login/'
rp({url: getLoginUrl, jar: this.cookieJar, method: 'GET'})
.then((body) => {
var csrftoken = this.cookieJar.getCookies(getLoginUrl)[1].toString().split('=')[1].split(';')[0];
var args = {
url: postLoginUrl,
json: true,
method: 'POST',
data: {
username: this.username,
password: this.password
},
headers: {
'method': 'POST',
'path': '/account/login/',
'cookie': 'csrftoken=' + csrftoken,
},
jar: this.cookieJar,
resolveWithFullResponse: true
}
rp(args)
.then((response) => {
res.loginResponse = response; // save the response for later use
console.log('Post demourl.com/account/login success');
next();
})
.catch((error) => {
console.log('Post demourl.com/account/login error: ', error);
return res.send(error) //send the error
});
})
.catch((error) => {
console.log('Get demourl.com error: ', error);
return res.send(error) //send the error
});
}
module.exports = login

I never see this.cookieJar being defined. Make sure it's initialized somewhere:
this.cookieJar = request.jar();
If you only use a single cookieJar in your application, you could also use Request's global cookie jar by setting the option jar to true:
// Either by setting it as the default
const request = require('request').defaults({jar: true});
// Or by setting it on each request
request('www.example.com', { jar: true });
