问题描述
我想在不使用 twitter4j 的情况下使用 Twitter Rest Api.Fabric很好，但我找不到像gettingUserFollowers()这样的方法.我不知道为什么它有.无论如何，我想使用此服务调用我的用户关注者 ID.https://dev.twitter.com/rest/reference/get/followers/ids
我查看了 Fabric 网站上的教程(http://docs.fabric.io/android/twitter/access-rest-api.html#tweets).有一个用于获取定制服务的类.但我无法理解如何调用它发送参数.我将其更改为以下
import com.twitter.sdk.android.core.TwitterApiClient;导入 com.twitter.sdk.android.core.TwitterSession;进口改造.http.GET;导入改造.http.Query;公共类 MyTwitterApiClient 扩展了 TwitterApiClient {公共 MyTwitterApiClient(TwitterSession 会话){代谢);}公共自定义服务 getCustomService() {返回 getService(CustomService.class);}接口自定义服务{@GET("/1.1/followers/ids.json")void show(@Query("user_id") long id);}}我认为当我发送一个 ID 时，服务会带来关注者 ID.
MyTwitterApiClient aa = new MyTwitterApiClient(session);aa.getCustomService().show(userId);但应用已停止.我怎么了?
LogCat 是

实际上，Fabric 使用改造来进行 REST Api 调用，并且如前所述在 Fabric 文档中，为了获取我们需要传递的关注者的 iduser_id 作为参数并检索列表作为响应.
MyTwitterApiClient.java
import com.twitter.sdk.android.core.Callback;导入 com.twitter.sdk.android.core.TwitterApiClient;导入 com.twitter.sdk.android.core.TwitterSession;进口改造.client.Response;进口改造.http.GET;导入改造.http.Query;公共类 MyTwitterApiClient 扩展了 TwitterApiClient {公共 MyTwitterApiClient(TwitterSession 会话){代谢);}/*** 为 CustomService 提供定义的端点*/公共自定义服务 getCustomService() {返回 getService(CustomService.class);}}//示例用户/显示服务端点接口自定义服务{@GET("/1.1/followers/ids.json")void list(@Query("user_id") long id, Callback cb);} <块引用>
现在在 MainActivity 中，我们将对用户进行身份验证，然后通过获取会话我们将检索对应的所有关注者的列表到用户 ID.
MainActivity.java
公共类 MainActivity 扩展 AppCompatActivity {//注意:您的消费者密钥和秘密应该在发送之前在您的源代码中进行混淆.private static final String TWITTER_KEY = "YOUR_TWITTER_KEY";private static final String TWITTER_SECRET = "YOUR_TWITTER_SECRET";TwitterLoginButton loginButton;SharedPreferences 共享；@覆盖protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET);Fabric.with(this, new Twitter(authConfig), new Crashlytics());setContentView(R.layout.activity_main);shared = getSharedPreferences("demotwitter", Context.MODE_PRIVATE);loginButton = (TwitterLoginButton) findViewById(R.id.login_button);loginButton.setCallback(new Callback() {@覆盖公共无效成功(结果结果){//用结果做一些事情，它提供了一个 TwitterSession 来进行 API 调用TwitterSession 会话 = Twitter.getSessionManager().getActiveSession();TwitterAuthToken authToken = session.getAuthToken();字符串令牌 = authToken.token;字符串秘密 = authToken.secret;//这里我们得到了用户推特账户的所有详细信息System.out.println(result.data.getUserName()+ result.data.getUserId());Twitter.getApiClient(session).getAccountService().verifyCredentials(true, false, new Callback() {@覆盖公共无效成功(结果<用户>用户结果){用户用户 = userResult.data;//这里我们得到了图像url，可用于在任何需要的地方设置为图像.System.out.println(user.profileImageUrl+" "+user.email+""+user.followersCount);}@覆盖公共无效失败(TwitterException e){}});shared.edit().putString("tweetToken", token).commit();shared.edit().putString("tweetSecret", secret).commit();TwitterAuthClient authClient = new TwitterAuthClient();authClient.requestEmail(会话，新回调<字符串>(){@覆盖公共无效成功(结果<字符串>结果){//对结果做一些事情，它提供了//电子邮件地址System.out.println(result.toString());Log.d("Result", result.toString());Toast.makeText(getApplicationContext(), result.data,Toast.LENGTH_LONG).show();}@覆盖公共无效失败(TwitterException 异常){//失败时做一些事情System.out.println(exception.getMessage());}});MyTwitterApiClient apiclients=new MyTwitterApiClient(session);apiclients.getCustomService().list(result.data.getUserId(), new Callback() {@覆盖公共无效失败(TwitterException arg0){//TODO 自动生成的方法存根}@覆盖公共无效成功(结果<响应> arg0){//TODO 自动生成的方法存根BufferedReader 阅读器 = null;StringBuilder sb = new StringBuilder();尝试 {reader = new BufferedReader(new InputStreamReader(arg0.response.getBody().in()));字符串线；尝试 {while ((line = reader.readLine()) != null) {sb.append(line);}} catch (IOException e) {e.printStackTrace();}} catch (IOException e) {e.printStackTrace();}字符串结果 = sb.toString();System.out.println("响应是>>>>>>>>>"+result);尝试 {JSONObject obj=new JSONObject(result);JSONArray ids=obj.getJSONArray("ids");//这是我们获得关注者ID的地方for(int i=0;i<ids.length();i++){System.out.println("用户ID"+(i+1)+"为"+ids.get(i));}} catch (JSONException e) {//TODO 自动生成的 catch 块e.printStackTrace();}}});}@覆盖公共无效失败(TwitterException 异常){//失败时做一些事情}});}@覆盖protected void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);//将活动结果传递给登录按钮.loginButton.onActivityResult(requestCode, resultCode, data);}} I want to use Twitter Rest Api without using twitter4j. Fabric is fine but i couldn't find a method like gettingUserFollowers(). I don't know why it has. Anyway I want to call my user followers ids using this service. https://dev.twitter.com/rest/reference/get/followers/ids
I have looked a tutorial from fabric website(http://docs.fabric.io/android/twitter/access-rest-api.html#tweets). There is a class for getting a custom service. But i couldn't understan how i can call it sending parameter.I changed it as following
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);
}
}
I think when i send an id ,service brings followers ids.
MyTwitterApiClient aa = new MyTwitterApiClient(session);
aa.getCustomService().show(userId);
But app is stopped.What is my wrong ?

解决方案
Actually Fabric uses retrofit to make REST Api calls and as mentioned in Fabric documentation, for getting ids of followers we need to pass user_id as parameter and retrieve list in response.
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);
}
Now in MainActivity we will authenticate the user and then by getting the session we will retrieve the list of all followers corresponding to a userid.
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";
TwitterLoginButton loginButton;
SharedPreferences shared;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY, TWITTER_SECRET);
Fabric.with(this, new Twitter(authConfig), new Crashlytics());
setContentView(R.layout.activity_main);
shared = getSharedPreferences("demotwitter", Context.MODE_PRIVATE);
loginButton = (TwitterLoginButton) findViewById(R.id.login_button);
loginButton.setCallback(new Callback<TwitterSession>() {
@Override
public void success(Result<TwitterSession> result) {
// Do something with result, which provides a TwitterSession for making API calls
TwitterSession session = Twitter.getSessionManager()
.getActiveSession();
TwitterAuthToken authToken = session.getAuthToken();
String token = authToken.token;
String secret = authToken.secret;
//Here we get all the details of user's twitter account
System.out.println(result.data.getUserName()
+ result.data.getUserId());
Twitter.getApiClient(session).getAccountService()
.verifyCredentials(true, false, new Callback<User>() {
@Override
public void success(Result<User> userResult) {
User user = userResult.data;
//Here we get image url which can be used to set as image wherever required.
System.out.println(user.profileImageUrl+" "+user.email+""+user.followersCount);
}
@Override
public void failure(TwitterException e) {
}
});
shared.edit().putString("tweetToken", token).commit();
shared.edit().putString("tweetSecret", secret).commit();
TwitterAuthClient authClient = new TwitterAuthClient();
authClient.requestEmail(session, new Callback<String>() {
@Override
public void success(Result<String> result) {
// Do something with the result, which provides the
// email address
System.out.println(result.toString());
Log.d("Result", result.toString());
Toast.makeText(getApplicationContext(), result.data,
Toast.LENGTH_LONG).show();
}
@Override
public void failure(TwitterException exception) {
// Do something on failure
System.out.println(exception.getMessage());
}
});
MyTwitterApiClient apiclients=new MyTwitterApiClient(session);
apiclients.getCustomService().list(result.data.getUserId(), new Callback<Response>() {
@Override
public void failure(TwitterException arg0) {
// TODO Auto-generated method stub
}
@Override
public void success(Result<Response> arg0) {
// TODO Auto-generated method stub
BufferedReader reader = null;
StringBuilder sb = new StringBuilder();
try {
reader = new BufferedReader(new InputStreamReader(arg0.response.getBody().in()));
String line;
try {
while ((line = reader.readLine()) != null) {
sb.append(line);
}
} catch (IOException e) {
e.printStackTrace();
}
} catch (IOException e) {
e.printStackTrace();
}
String result = sb.toString();
System.out.println("Response is>>>>>>>>>"+result);
try {
JSONObject obj=new JSONObject(result);
JSONArray ids=obj.getJSONArray("ids");
//This is where we get ids of followers
for(int i=0;i<ids.length();i++){
System.out.println("Id of user "+(i+1)+" is "+ids.get(i));
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
}
@Override
public void failure(TwitterException exception) {
// Do something on failure
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// Pass the activity result to the login button.
loginButton.onActivityResult(requestCode, resultCode, data);
}
}
