在尝试访问用户详细信息时，我收到此错误：

我无法在回调方法上捕获断点。如果您遇到此错误，请帮助。

以下是我获取用户详细信息的代码：

private void onSessionStateChange(Session session, SessionState state, Exception exception) {
    //RFR//_("onSessionStateChange----------------");
   /////////////// super.onSessionStateChange(state, exception);
    if (state.isOpened()) {
        readUserInfo(session);
    } else if (state.isClosed()) {
        // Session closed
    }
}

private Request.GraphUserCallback graphCallback = new Request.GraphUserCallback() {

      // callback after Graph API response with user object
      @Override
      public void onCompleted(GraphUser user, Response response) {
          String name = user.getName();
          String gender = (String) user.getProperty("gender");
          String email = (String) user.getProperty("email");
          String birthday = user.getBirthday();
          Log.d("FB----->","name: "+ name +" gender: "+ gender +" email: "+ email +" birthday: " +birthday);

      }

};

    public void readUserInfo(Session session){
        // make request to the /me API
        Request.executeMeRequestAsync(session, graphCallback);
    }

以下是我设置的权限：

openRequest.setPermissions(Arrays.asList("user_birthday", "email", "user_location"));

这是我从浏览器检查时从图形 api 得到的响应：

{
  "id": "1000000XXXXX930",
  "name": "First Last",
  "first_name": "First",
  "last_name": "Last",
  "link": "http://www.facebook.com/<myusername>",
  "username": "<myusername>",
  "gender": "male",
  "locale": "en_US"
}

  • 抛出异常，因为您正在尝试访问电子邮件
  • 但是用户没有使用电子邮件进行注册，而是使用了电话号码进行注册。
  • 您必须在代码中检查子响应是否具有密钥的可能性，然后才尝试提取该密钥的值
if(object.has("email")){
   userEmail = object.getString("email");
}

您是否授予“电子邮件”权限以请求 Facebook 应用程序访问任何用户的电子邮件 ID？

如果您想使用 API 访问 Facebook 用户的电子邮件 ID，那么您必须授予电子邮件权限。有关用户个人资料的一般信息不会为您提供 Facebook 用户的电子邮件地址。

Facebook API 中的电子邮件权限

注意：一些用户还设置了安全性，不与任何其他人共享任何电子邮件地址，那么您也可能无法获得电子邮件地址。

希望它会帮助你。

这段代码在获得所需权限方面与我配合良好，这也将帮助您获得电子邮件权限

  private void FaceBookSignIn()
   {
   facebookBtn.setOnClickListener(new View.OnClickListener() {

   @Override
   public void onClick(View arg0) {
       Session currentSession = Session.getActiveSession();
        if (currentSession == null || currentSession.getState().isClosed()) {
            Session session = new Session.Builder(context).build();
            Session.setActiveSession(session);
            currentSession = session;
        }

        if (currentSession.isOpened()) {
               Session.openActiveSession(SignIn_Rewards.this, false, new Session.StatusCallback() {

                      @Override

你有这样的检查：

private Request.GraphUserCallback graphCallback = new Request.GraphUserCallback() {

  // callback after Graph API response with user object
  @Override
  public void onCompleted(GraphUser user, Response response) {
      String name = user.getName();
      String gender = (String) user.getProperty("gender");
      String email = (String) user.getProperty("email");
      String birthday = user.getBirthday();

     if(email!=null){
     //perform your task here.
     }else{
     Log.v("email","is empty");
     }

      Log.d("FB----->","name: "+ name +" gender: "+ gender +" email: "+ email +" birthday: " +birthday);

  }};

试试这个以获得电子邮件的价值 已 编辑：默认情况下，您不会收到电子邮件，对于电子邮件，您必须指定权限。

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

            @Override
            public void call(Session session, SessionState state, Exception exception) 
            {
                if(session.isOpened())
                {
                    Request.executeMeRequestAsync(session, new Request.GraphUserCallback() 
                    {

                        @Override
                        public void onCompleted(GraphUser user, Response response) 
                        {

                            if(user != null)
                            {
                                try
                                {
                                    System.out.println("Graph Inner Json"+user.getInnerJSONObject());
                                    String email = user.getInnerJSONObject().getString("email");
                                }
                             }
                         }
                     }
                 }
            }

YourActivityName.openActiveSession(this, true, statusCallback);

这是openActiveSession()我们指定权限的地方

private static Session openActiveSession(Activity activity, boolean allowLoginUI, Session.StatusCallback statusCallback)
    {
        OpenRequest openRequest = new OpenRequest(activity);
        openRequest.setPermissions(Arrays.asList("user_birthday", "email"));
        openRequest.setCallback(statusCallback);

        Session session = new Session.Builder(activity).build();

        if(SessionState.CREATED_TOKEN_LOADED.equals(session.getState()) || allowLoginUI)
        {
            Session.setActiveSession(session);
            session.openForRead(openRequest);

            return session;
        }

        return null;
    }

最后，您应该在onActivityResultMethod 中执行以下操作：

if(Session.getActiveSession() != null)
        {
            Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
        }

您确实需要获取某人的电子邮件的权限，尽管有些人设置了他们的隐私，这样您就可以在没有此明确许可的情况下获取他们的电子邮件，大多数人不需要。
