Twitter authentication with Javascript

问题

I want to get an access_token according to this documentation http://dev.twitter.com/doc/post/oauth/request_token. I use javascript.

$.ajax({
    url: "http://api.twitter.com/oauth/request_token",
    type: "POST",
    contentType: "json",
    data: {
        oauth_consumer_key: "DFwQqCnOTaYVbZQdBFqpR",
        oauth_signature_method: "HMAC-SHA1",
        oauth_timestamp: parseInt((new Date()).getTime() / 1000),
        oauth_nonce: "R" + parseInt((new Date()).getTime() / 1000),
        oauth_version: "1.0"
    },
    success: function (data) {
        debugger;
    },
    error: function (a, b, c) {
        debugger;
    }
});

But it does not work at all. Always return error, never success.

回答1:

You are not signing your request. You can read a more in depth direction on how to sign an OAuth reqeust on dev.twitter.com. You will likely want to use a JavaScript library to generate oauth_signature.

回答2:

Check user login & signup provided by Twitter's @Anywhere JavaScript library. https://dev.twitter.com/docs/anywhere/welcome#login-signup

That may be exactly what you want, much easier to use than the raw OAuth.

回答3:

You're probably calling this script outside the api.twitter.com domain. Try with dataType: "jsonp".
