Android:如何使用Graph API从Facebook日历中获取朋友的出生日期

Question

我正在申请需要所有朋友的出生日期的申请.有些人可以使用图形API分享如何获取所有朋友的出生日期的代码.我正在使用以下代码:

// start Facebook Login
    Session.openActiveSession(this, true, new Session.StatusCallback() {

      // callback when session changes state
      @Override
      public void call(Session session, SessionState state, Exception exception) {
        if (session.isOpened()) {

          // make request to the 
            Request.executeMyFriendsRequestAsync(session, new Request.GraphUserListCallback() {

                @Override
                public void onCompleted(List<GraphUser> users, Response response) {
                    //Log.d("AL",""+users.size() + response.toString());
                    for (int i=0;i<users.size();i++){
                        Log.d("AL",""+users.get(i).toString());
                        welcome.setText("Done");
                    }

                }
            });
        }
      }
    });

这只是回复朋友的名字和身份.我必须设置权限才能获得朋友生日？我是facebook SDK的新手.并使用SDK v3.

图形api在json结果后返回

{Response:  responseCode: 200, graphObject: GraphObject{graphObjectClass=GraphObject, state={"data":[{"id":"1580811776","name":"Jamal Abdul Nasir"},{"id":"1610349118","name":"Ahmed Nawaz"}],"paging":{"next":"https:\/\/graph.facebook.com\/100004790803061\/friends?format=json&access_token=AAABtTr8g5U4BANiJdCiBFxQeg0l1eqYYzmSWVM8G1UlyAhTtUrAsoEZAgU19dECXTE2nw7pHIz8bDb7OJGM4wAwzusOVZAQN8yaiYVsQZDZD&limit=5000&offset=5000&__after_id=1610349118"}}}, error: null, isFromCache:false}

哪个没有生日.

Answer 1

首先定义你的回调,你会得到朋友和生日信息,如果经过身份验证:

Session.StatusCallback statusCallback =  new Session.StatusCallback() {

  // callback when session changes state
  @Override
  public void call(Session session, SessionState state, Exception exception) {
    if (session.isOpened()) {
        // Private method, to be defined
        makeFriendsRequest();
    }
  }

};

然后,您可以打开会话并传递必要的"friends_birthday"权限请求:

Session session = new Session(this);
session.openForRead(new Session.OpenRequest(this)
                       .setCallback(statusCallback)
                       .setPermissions(Arrays.asList("friends_birthday")));

最后,这里是您可以用来获取朋友信息的后验证方法,包括生日:

private void makeFriendsRequest() {
    Request myFriendsRequest = Request.newMyFriendsRequest(Session.getActiveSession(), 
            new Request.GraphUserListCallback() {

        @Override
        public void onCompleted(List<GraphUser> users, Response response) {
            if (response.getError() == null) {
                // Handle response
            }

        }

    });
    // Add birthday to the list of info to get.
    Bundle requestParams = myFriendsRequest.getParameters();
    requestParams.putString("fields", "name,birthday");
    myFriendsRequest.setParameters(requestParams);
    myFriendsRequest.executeAsync();
}
