invalid oauth2 token request
google-api, node.js, oauth, oauth-2.0
Solution
It turns out that request.js (https://github.com/mikeal/request) doesn't automatically include the content-length to the headers. I added it manually and it worked on the first try. I've pasted the code below:
exports.get_token = function(req,success,fail){
var token;
var request = require('request');
var credentials = require('../config/credentials');
var google_credentials=credentials.fetch('google');
var token_request='code='+req['query']['code']+
'&client_id='+google_credentials['client_id']+
'&client_secret='+google_credentials['client_secret']+
'&redirect_uri=http%3A%2F%2Fmyurl.com:3000%2Fauth'+
'&grant_type=authorization_code';
var request_length = token_request.length;
console.log("requesting: "+token_request);
request(
{ method: 'POST',
headers: {'Content-length': request_length, 'Content-type':'application/x-www-form-urlencoded'},
uri:'https://accounts.google.com/o/oauth2/token',
body: token_request
},
function (error, response, body) {
if(response.statusCode == 200){
console.log('document fetched');
token=body['access_token'];
store_token(body);
if(success){
success(token);
}
}
else {
console.log('error: '+ response.statusCode);
console.log(body)
if(fail){
fail();
}
}
}
);
}
Problem
I'm developing a node application which needs to authenticate with google. When I request a token, https://accounts.google.com/o/oauth2/token responds with: ``` error: 400 { "error" : "invalid_request" } ``` I've tried making the same request in curl, and have received the same error, so I suspect there is something wrong with my request but I can't figure out what. I've pasted my code below: ``` var request = require('request'); var token_request='code='+req['query']['code']+ '&client_id={client id}'+ '&client_secret={client secret}'+ '&redirect_uri=http%3A%2F%2Fmassiveboom.com:3000'+ '&grant_type=authorization_code'; request( { method: 'POST', uri:'https://accounts.google.com/o/oauth2/token', body: token_request }, function (error, response, body) { if(response.statusCode == 201){ console.log('document fetched'); console.log(body); } else { console.log('error: '+ response.statusCode); console.log(body); } }); ``` I've triple checked to make sure all the data I'm submitting is correct and i'm still getting the same error. What can I do to debug this further?
