requestData is out of scope in get("/callback") request

[plamalfa]

Had to define requestData as a global variable to use in the get request for the callback URL.

let _requestData;
app.get("/authorize", function(req, res) {
  var oAuth = new Discogs().oauth();
  oAuth.getRequestToken(
    "sdfasdfadslfkjasdhf",
    "asdlfkjahsdflkajsdhf",
    "http://localhost:3000/callback",
    function(err, requestData) {
      _requestData = requestData;
      // Persist "requestData" here so that the callback handler can
      // access it later after returning from the authorize url
      res.redirect(requestData.authorizeUrl);
    }
  );
});

app.get("/callback", function(req, res) {
  var oAuth = new Discogs(_requestData).oauth();
  oAuth.getAccessToken(
    req.query.oauth_verifier, // Verification code sent back by Discogs
    function(err, accessData) {
      // Persist "accessData" here for following OAuth calls
      res.send("Received access token!");
    }
  );
});

Is the code above how you had intended the package to be used? A more complete example of these get requests in action would be helpful to understand their uses.

The global variable is your implementation of my comments

// Persist "requestData" here so that the callback handler can
// access it later after returning from the authorize url

I could give a literal example, but I just want to indicate one should store it somewhere in a scope so that it can be accessed by another request handler.

I could change it to something like this:

// Persist "requestData" here (in a global variable for example) so that the 
// callback handler can access it later after returning from the authorize url
