Question

我正在开发一个Android应用程序，我需要在Facebook上登录并获取Facebook好友。

我正在使用以下代码获取Facebook好友：

公共类FriendsRequestListener实现RequestListener {

/**
 * Called when the request to get friends has been completed.
 * Retrieve and parse and display the JSON stream.
 */
public void onComplete(final String response) {
    try {
        // process the response here: executed in background thread
        Log.d("Facebook-Example-Friends Request", "response.length(): " + 
                response.length());
        Log.d("Facebook-Example-Friends Request", "Response: " + response);

        final JSONObject json = new JSONObject(response);
        JSONArray d = json.getJSONArray("data");
        int l = (d != null ? d.length() : 0);
        Log.d("Facebook-Example-Friends Request", "d.length(): " + l);

        for (int i=0; i<l; i++) {
            JSONObject o = d.getJSONObject(i);
            String n = o.getString("name");
            String id = o.getString("id");
        }

        // Only the original owner thread can touch its views

    } catch (JSONException e) {
        Log.w("Facebook-Example", "JSON Error in response");
    }
}

@Override
public void onComplete(String response, Object state) {
    // TODO Auto-generated method stub

}

@Override
public void onIOException(IOException e, Object state) {
    // TODO Auto-generated method stub

}

@Override
public void onFileNotFoundException(FileNotFoundException e, Object state) {
    // TODO Auto-generated method stub

}

@Override
public void onMalformedURLException(MalformedURLException e, Object state) {
    // TODO Auto-generated method stub

}

@Override
public void onFacebookError(FacebookError e, Object state) {
    // TODO Auto-generated method stub

}

}

调用此类的方法：

mAsyncRunner = new AsyncFacebookRunner(facebook);
                mAsyncRunner.request("me/friends", new FriendsRequestListener());

问题是我的代码在上面的代码调用时没有做任何事情。

Answer 1

你可以使用这个 api https://graph.facebook.com/v1.0/me/friends?fields=picture,id,username&limit=${limit}&access_token=${accessToken}

这是一个 v1.0 api，允许用户获取所有好友列表

Answer 2

要获取所有Facebook好友列表，您需要获得“taggable_friends”

GraphRequestAsyncTask r = GraphRequest.newGraphPathRequest(fbToken,
        "/me/taggable_friends", new Callback() {

            @Override
            public void onCompleted(GraphResponse response) {
                //here you can parse the response
            }
        }

fbToken是您登录时的令牌。但是，facebook使用分页，所以你需要从朋友请求获取下一页然后下一个值，这样你就可以解析它。

response.getJSONObject("paging").getString("next");

使用StringRequest获取下一页用户

StringRequest sr = new StringRequest(Request.Method.GET, next,
        new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {

                JSONObject friends = null;
                try {
                    friends = new JSONObject(response);
                    parseResponse(friends);
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        }, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
    }
