java - 从 Linkedin 得到空白回复

Question

我试图在 Codename 一个应用程序中成功登录后请求用户信息，但是当登录用户重定向到该应用程序时，却没有得到任何响应。

以下是我的代码:

linked.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent evt) {


               Oauth2 auth2 = new Oauth2("https://www.linkedin.com/oauth/v2/authorization", 
                "XXXXXXXXXX", 
                "https://www.codenameone.com","", 
                "https://www.linkedin.com/oauth/v2/accessToken", 
                "XXXXXXXXXX");

       //auth2.authenticate();
        auth2.showAuthentication(new ActionListener() {
                   @Override
                   public void actionPerformed(ActionEvent evt) {
                       AccessToken token = (AccessToken) evt.getSource();
                       JSONObject object = new JSONObject(token);
                       try {
                           TOKEN = object.getString("token");
                           Log.p(TOKEN);


                             ConnectionRequest linkedinreq = new ConnectionRequest(){
                   @Override
                   protected void readResponse(InputStream input) throws IOException {
                      Log.p(input.toString());
                   }

             };
             linkedinreq.setPost(false);
             linkedinreq.setUrl("https://api.linkedin.com/v1/people/~:(id,num-connections,picture-url)");
             linkedinreq.addArgumentNoEncoding("oauth2_access_token", TOKEN);
            linkedinreq.addArgumentNoEncoding("format", "json");
             NetworkManager.getInstance().addToQueue(linkedinreq);


                       } catch (JSONException ex) {
                           ex.printStackTrace();
                       }
                   }
               });
                Oauth2.setBackToParent(true);


       }
        });

以及显示空响应的网络监视器快照

并在控制台输出显示

[Network Thread] 0:0:1,12 - com.codename1.impl.javase.JavaSEPort$67@41ca2b3e

覆盖此消息后，您可以收到任何错误消息并调用 setreadResponseErrors(true)；这将显示错误消息和响应代码。

linkedinreq.setReadResponseForErrors(true);
     @Override
                protected void handleErrorResponseCode(int code, String message) {
                    System.out.println("code: " + code + "message: " + message);
                }
