Instapaper API & Javascript XAuth

问题:

I've spent most of today try to implement Instapaper's XAuth API. I haven't even been able to get an oauth token, yet.

Any ideas what I'm doing wrong?

I'm using node.js and the oauth module. It's my understanding that I need to pass the username, password, amd mode as extra parameters. And the oauth module should take care of all of the oauth parameters. But it's not. Here's the code:

var OAuth = require('oauth').OAuth;  var oauth = new OAuth(   '',   'https://www.instapaper.com/api/1/oauth/access_token',   'CONSUMER_KEY',   'CONSUMER_SECRET',   '1.0',   null,   'HMAC-SHA1',   null );  var extra = {   'x_auth_username': 'USERNAME',   'x_auth_password': 'PASSWORD',   'x_auth_mode': 'client_auth' }; var hello = oauth._prepareParameters('', '', 'POST', 'https://www.instapaper.com/api/1/oauth/access_token', null); var url = 'https://www.instapaper.com/api/1/oauth/access_token'; var f = true; for (var i in hello) {   if (f) {     url += '?';     f = false;   } else {     url += '&';   }   url += hello[i][0] + '=' + hello[i][1]; } console.log(url+'&x_auth_mode=client_auth&x_auth_username=&x_auth_password=') oauth._performSecureRequest('', '', "POST", url+'&x_auth_mode=client_auth&x_auth_username=&x_auth_password=', null, null, null, function(error, data, response) {   console.log(error, data) });

And it returns this:

{ statusCode: 401,   data: 'oauth_signature [pWRf4W9k9nogID/O90Ng29bR2K0=] does not match expected value [eqJ8zD1bKeUa3InpDyegGDAbSnM=]' } 'oauth_signature [pWRf4W9k9nogID/O90Ng29bR2K0=] does not match expected value [eqJ8zD1bKeUa3InpDyegGDAbSnM=]'}

So I am not sure whether this is an error with the oauth module or if Instapaper's API is too strict in parsing the Authorization headers, but I had to add a space after the comma for the header delimiter. At any rate this seems to be causing all the issues (400 errors).

oauth currently builds up headers as:

oauth_consumer_key=SomeKey,oauth_consumer_secret=SomeSecret...

needed to be

oauth_consumer_key=SomeKey, oauth_consumer_secret=SomeSecret...

I modified the oauth.js file to reflect this. https://github.com/ciaranj/node-oauth/blob/master/lib/oauth.js#L121

added a space after the comma towards the end of the line

authHeader+= "" + this._encodeData(orderedParameters[i][0])+"=\""+ this._encodeData(orderedParameters[i][1])+"\", ";

Here is my working client sample:

var OAuth = require('oauth').OAuth;  var consumerKey    = 'chill'; var consumerSecret = 'duck';  var oa = new OAuth(   null,   'https://www.instapaper.com/api/1/oauth/access_token',   consumerKey,   consumerSecret,   '1.0',   null,   'HMAC-SHA1' );  var x_auth_params = {   'x_auth_mode': 'client_auth',   'x_auth_password': 'yourpass',   'x_auth_username': 'yourusername@whatever.com' };  oa.getOAuthAccessToken(null, null, null, x_auth_params, function (err, token, tokenSecret, results) {    // CAN HAZ TOKENS!   console.log(token);   console.log(tokenSecret);    // ZOMG DATA!!!   oa.get("https://www.instapaper.com/api/1/bookmarks/list", token, tokenSecret,  function (err, data, response) {      console.log(data);    });  });

Hope this helps!

Derek's answer is right about the missing space as being the problem, but you don't need to edit oauth.js.

After creating the OAuth client, just set the separator string:

var OAuth = require('oauth').OAuth; var oa = new OAuth({...}); oa._oauthParameterSeperator = ', ';

(yes, "sepErator", there's a typo in the module's code)
