OAuth callback isn't called

[mariorodriguespt]

I tried to setup a callback but it's never called. The oauth documentation says that I must provide oauth_callback parameters but I get an error saying that the callback is missing. It works if I use callback, after the user grants the authorisation I'm shown a page with a verification token. What am I supposed to do with this token? Why the callback isn't called?

U shoul use the provided token to make the authenticated requests

[mariorodriguespt]

Isn't this token supposed to be passed to my server via the callback? All I'm getting is page, show to the user, with the token. The callback isn't being called.

I bet u r right. This is as far as i got too.

@sblaz Do your commits work or just WIP? Would love to see a PR for this. Currently stuck here ourselves.

[sblaz]

I believe so, yes, although I was planning on doing a bit more testing before submitting a pull request. I was able to successfully authenticate with an OAuthSwift client after applying this and a couple of other patches - I'm not sure what happens if you just try to apply this one by itself. It's pretty simple, though, if you look at it, the oauth_callback parameter wasn't getting saved along with the other request token stuff.

@sblaz Yup -- does look like that. Currently using your master branch -- removes the restrictive wp_http_validate_url looks like.

[sblaz]

Yes, that's right - I started by applying #33 but then wanted to use a custom url scheme so relaxed the validation further. Also had some issues with double-encoding of the oauth_callback parameter value. Applied #65 and then removed the two rawurlencode() calls in join_with_equals_sign() and it seems to be copacetic.

Those changes got it working for me with OAuthSwift.

In my case, normalize_parameters() is really messing up my already partially encoded parameters, so by removing normalize_parameters() instead, I was able to keep the rawurldecode() calls.

See: #91

@sblaz , I have created a PR which merges your changes with AlexC's and removes normalize_parameters() in favor of encoding them in the join_with_equals_sign() function: #92
If you're interested, would you mind checking out my approach and let me know if it works for you? I'll leave the callback-fix branch on my fork available for testing.

Thanks!
