Android第三方授权(新浪微博篇)

Android第三方认证新浪微博，相对微信，也比较简单，并且sina给了一个sdk和sdkdemo，这个demo封装了许多，但是自己不准备记录这个demo，而是直接使用sdk

同样去sina官方下载sdk，自己去搜吧，地址不给了

1.初始化SsoHandler

 AuthInfo mWeiboAuthInfo = new AuthInfo(this, Constants.APP_KEY, Constants.REDIRECT_URL, Constants.SCOPE);
 SsoHandler mSsoHandler = new SsoHandler(this, mWeiboAuthInfo);

其中几个常量的解释可以到官网查看

2.开始授权

 mSsoHandler.authorize(new MyWeiboAuthListener(new LoginWeiboGetUserInfoListener()));
 private static class MyWeiboAuthListener implements WeiboAuthListener {

         private RequestListener mRequestUserInfoListener = null;

         public MyWeiboAuthListener(RequestListener requestUserInfoListener){
             this.mRequestUserInfoListener = requestUserInfoListener;
         }

         @Override
         public void onCancel() {
             // TODO Auto-generated method stub
             Toast.makeText(mContext, "已取消微博登录", Toast.LENGTH_SHORT).show();
         }

         @Override
         public void onComplete(Bundle values) {
             // TODO Auto-generated method stub
             mAccessToken = Oauth2AccessToken.parseAccessToken(values);
             if (mAccessToken.isSessionValid()) {
                 // 保存 Token 到 SharedPreferences
                 WeiboParameters weiboParameters = new WeiboParameters(
                         Constants.APP_KEY);
                 weiboParameters.put("access_token", mAccessToken.getToken());

                 if( mWeiboRunner == null ){
                     mWeiboRunner = new AsyncWeiboRunner(
                         mContext);
                 }

                 if( mRequestUserInfoListener == null ){
                     return;
                 }
                 mWeiboRunner.requestAsync(WEIBO_USERID_URL,
                         weiboParameters, "POST",
                         mRequestUserInfoListener);

             } else {
                 // 当您注册的应用程序签名不正确时，就会收到 Code，请确保签名正确
                 String code = values.getString("code", "");
                 Log.i(TAG, "应用签名不正确 code = " + code);
                 Toast.makeText(mContext, "微博认证失败", Toast.LENGTH_SHORT).show();

             }
         }

         @Override
         public void onWeiboException(WeiboException arg0) {
             // TODO Auto-generated method stub

         }

     }

 /**

      *
      */
     private static class LoginWeiboGetUserInfoListener implements RequestListener {

         @Override
         public void onComplete(String result) {
             // TODO Auto-generated method stub
             JSONObject userObject = JSON.parseObject(result);
             String weiboUid = userObject.getString("uid");
             if( TextUtils.isEmpty(weiboUid)){
                 Log.e(TAG, "weibo uid = null ");
                 return;
             }

             Log.i(TAG, "weibo uid = " + weiboUid );
             uid = weiboUid;
             WeiboParameters weiboParameters = new WeiboParameters(Constants.APP_KEY);
             weiboParameters.put("uid", weiboUid);
             weiboParameters.put("access_token", mAccessToken.getToken());
             if( mWeiboRunner == null ){
                 mWeiboRunner = new AsyncWeiboRunner(
                     mContext);
             }

             mWeiboRunner.requestAsync(WEIBO_USERINFO_URL, weiboParameters, "GET", new MyWeiboHandleUserInfoListener());
         }

         @Override
         public void onWeiboException(WeiboException exception) {
             // TODO Auto-generated method stub
             exception.printStackTrace();

         }

     }

 /**
      * 处理获取的用户信息
      * @author ReCwert
      *
      */
     private static class MyWeiboHandleUserInfoListener implements RequestListener{

         @Override
         public void onComplete(String result) {
             // TODO Auto-generated method stub
             JSONObject userData = JSON.parseObject(result);
             nickName = userData.getString("name");
             headUrl = userData.getString("profile_image_url");
             sex = userData.getString("gender");
             Log.i(TAG, "uid = " + uid );
             Log.i(TAG, "nickName = " + nickName);
             Log.i(TAG, "headUrl = " + headUrl );
             Log.i(TAG, "sex = " + sex);
         }

         @Override
         public void onWeiboException(WeiboException exception) {
             // TODO Auto-generated method stub
             exception.printStackTrace();
         }

     }

可以看到，我们在第一个回调中只是获得了access_token，我们需要根据这个access_token去获取跟多的信息，比如去请求userid 和userinfo

 private static final String WEIBO_USERID_URL = "https://api.weibo.com/oauth2/get_token_info";
 private static final String WEIBO_USERINFO_URL = "https://api.weibo.com/2/users/show.json";

当然，更多的信息获取的url在sina官方能够查看到
