我想不使用twitter4j而使用Twitter Rest Api。面料很好,但是我找不到像getingUserFollowers()这样的方法。我不知道为什么会这样。无论如何,我想使用此服务给我的用户关注者ID。 https://dev.twitter.com/rest/reference/get/followers/ids

我看过面料网站(http://docs.fabric.io/android/twitter/access-rest-api.html#tweets)的教程。有一个用于获取定制服务的类。但是我不明白我怎么称呼它的发送参数。

import com.twitter.sdk.android.core.TwitterApiClient;
import com.twitter.sdk.android.core.TwitterSession;
import retrofit.http.GET;
import retrofit.http.Query;

public class MyTwitterApiClient extends TwitterApiClient  {

    public MyTwitterApiClient(TwitterSession session) {
        super(session);
    }

    public CustomService getCustomService() {
        return getService(CustomService.class);
    }

    interface CustomService {
        @GET("/1.1/followers/ids.json")
        void show(@Query("user_id") long id);
   }
}

我认为当我发送ID时,服务会带来关注者ID。
MyTwitterApiClient aa = new MyTwitterApiClient(session);
aa.getCustomService().show(userId);

但是应用已停止。我怎么了?

最佳答案

实际上,Fabric使用改造来进行REST Api调用,如上所述
在Fabric文档中,为了获取关注者的ID,我们需要传递
user_id作为参数,并作为响应检索列表。

MyTwitterApiClient.java

import com.twitter.sdk.android.core.Callback;
import com.twitter.sdk.android.core.TwitterApiClient;
import com.twitter.sdk.android.core.TwitterSession;
import retrofit.client.Response;
import retrofit.http.GET;
import retrofit.http.Query;

    public class MyTwitterApiClient extends TwitterApiClient {
        public MyTwitterApiClient(TwitterSession session) {
            super(session);
        }

        /**
         * Provide CustomService with defined endpoints
         */
        public CustomService getCustomService() {
            return getService(CustomService.class);
        }
    }

    // example users/show service endpoint
    interface CustomService {
        @GET("/1.1/followers/ids.json")
        void list(@Query("user_id") long id, Callback<Response> cb);
    }

现在在MainActivity中,我们将对用户进行身份验证,然后通过
在会话中,我们将检索所有对应的关注者列表
一个用户ID。

MainActivity.java
public class MainActivity extends AppCompatActivity {

    // Note: Your consumer key and secret should be obfuscated in your source code before shipping.
    private static final String TWITTER_KEY = "YOUR_TWITTER_KEY";
    private static final String TWITTER_SECRET = "YOUR_TWITTER_SECRET";
