什么是以及如何获取 Twitter 和 oauth-signpost 的 pinCode？

Question

我不知道pinCode 是什么，我也不知道如何得到它？！ 我找到了以下代码，如前所述，我们可以从 CallBack 中获取它，怎么能？如果有其他方法请告诉我..

代码

OAuthConsumer consumer = new DefaultOAuthConsumer(
                // the consumer key of this app (replace this with yours)
                "iIlNngv1KdV6XzNYkoLA",
                // the consumer secret of this app (replace this with yours)
                "exQ94pBpLXFcyttvLoxU2nrktThrlsj580zjYzmoM");

        OAuthProvider provider = new DefaultOAuthProvider(
                "http://twitter.com/oauth/request_token",
                "http://twitter.com/oauth/access_token",
                "http://twitter.com/oauth/authorize");

        /****************************************************
         * The following steps should only be performed ONCE
         ***************************************************/

        // we do not support callbacks, thus pass OOB
        String authUrl = provider.retrieveRequestToken(consumer, OAuth.OUT_OF_BAND);

        // bring the user to authUrl, e.g. open a web browser and note the PIN code
        // ...         

        String pinCode = // ... you have to ask this from the user, or obtain it
        // from the callback if you didn't do an out of band request

        // user must have granted authorization at this point
        provider.retrieveAccessToken(consumer, pinCode);

        // store consumer.getToken() and consumer.getTokenSecret(),
        // for the current user, e.g. in a relational database
        // or a flat file
        // ...

        /****************************************************
         * The following steps are performed everytime you
         * send a request accessing a resource on Twitter
         ***************************************************/

        // if not yet done, load the token and token secret for
        // the current user and set them
        consumer.setTokenWithSecret(ACCESS_TOKEN, TOKEN_SECRET);

        // create a request that requires authentication
        URL url = new URL("http://twitter.com/statuses/mentions.xml");
        HttpURLConnection request = (HttpURLConnection) url.openConnection();

        // sign the request
        consumer.sign(request);

        // send the request
        request.connect();

        // response status should be 200 OK
        int statusCode = request.getResponseCode();

用户必须在浏览器中访问 authUrl。该页面将要求他授权应用程序，然后告诉他密码。然后他必须将 pinCode 输入到您的应用程序中。

cmets 确实很好地描述了这一点。
