I am making a GET call with the following URL

https://auth.ebay.com/oauth2/authorize?client_id=CLIENT_ID&response_type=code&redirect_uri=REDIRECT_URI&scope=https://api.ebay.com/oauth/api_scope

This URL will redirect me to a "success.php" website from my server. With that redirection, it adds in params to the URL. For example: https://www.example.com/success.php?code=12345.

I need to get that code param from this redirection. How can I do that?

I tried to do a basic .get() call, but it doesnt seem to work..

https.get(url, (resp) => {
  let data = '';

  // A chunk of data has been received.
  resp.on('data', (chunk) => {
    data  = chunk;
  });

  // The whole response has been received. Print out the result.
  resp.on('end', () => {
    console.log(JSON.parse(data).explanation);
  });

}).on("error", (err) => {
  console.log("Error: "   err.message);
});

I have tried other ways that I thought would work from research on here, like waiting for the redirect, etc. Nothing seems to work.

CodePudding user response：

It is a query param ( seems to me you are working with an oAuth flow, reading about how these flows work would also help you work out an approach to this)

So I would capture it the following way

app.get('/callback', function (req, res) {

   var code = req.query.code || null;
   console.log(code);

}

where /callback is the URL you are redirected to and where you can capture the code to request the authorization token

CodePudding user response：

Based on the code you already have it seems you might want the following.

var https = require('https');
var url = 'https://auth.ebay.com/oauth2/authorize?client_id=CLIENT_ID&response_type=code&redirect_uri=REDIRECT_URI&scope=https://api.ebay.com/oauth/api_scope';
https.get(url, (resp) => {
  
  var location = new URL(resp.headers.location);
 
  var code = location.searchParams.get('code');
  
  console.log(code);
  
}).on("error", (err) => {
  console.log("Error: "   err.message);
});

My answer assumes you are writing the code that is making the request while @Jordi Riera assumes you are writing code to process the request. Might you tell us which it is?
