Question

我正在我的Android应用程序中使用他们的教程和文档实现一个登录流程，只要在StackOverflow中有几个答案。

我有一个带有Button的UserRegistrationActivity（不是“LoginButton”）。我想我要求正确的权限（basic_info，电子邮件）。我得到一个facebook对话框询问权限，但是电子邮件没有列在其中，所以当我得到access_token时，我无法访问用户电子邮件服务器端。

我的代码：

package com.test.user;

import java.util.Arrays;

import android.app.ProgressDialog;
import android.content.Intent;
import android.content.IntentSender.SendIntentException;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.text.TextUtils;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener; 
import android.widget.Toast;
import com.actionbarsherlock.app.SherlockActivity;
import com.actionbarsherlock.view.Menu;
import com.actionbarsherlock.view.MenuItem;
import com.actionbarsherlock.view.Window;
import com.facebook.Session;
import com.facebook.SessionState;
import com.test.user.domain.User;
import com.test.user.services.UserLoginService;

public class UserRegistrationActivity extends SherlockActivity implements  OnClickListener,ConnectionCallbacks,
OnConnectionFailedListener  {
private static final String TAG = "UserRegistrationActivity";
private static final int REQUEST_CODE_RESOLVE_ERR = 9000;
private ProgressDialog mConnectionProgressDialog;
private PlusClient mPlusClient;
private ConnectionResult mConnectionResult;
private Session session;
private Session.StatusCallback statusCallback =
new SessionStatusCallback();
SharedPreferences settings;
UserRegistrationActivity _activity;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
    setContentView(R.layout.activity_user_registration);
    settings = getSharedPreferences(TestApplication.PREFS_NAME, 0);

    setupActionBar();
    _activity = this;
}

public void onClickLogin(View v) {
    getSherlock().setProgressBarIndeterminateVisibility(true);
    Session session = Session.getActiveSession();
    if (session != null && !session.isOpened() && !session.isClosed()) {
        session.openForRead(new Session.OpenRequest(this)
        .setPermissions(Arrays.asList("basic_info","email"))
        .setCallback(statusCallback));
        } else {
        Session.openActiveSession(this, true, statusCallback);
    }
}

@Override
protected void onResume() {
    super.onResume();

}
private void setupActionBar() {
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    getSupportActionBar().setHomeButtonEnabled(true);
}
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {

        case android.R.id.home:
        // app icon in action bar clicked; go home
        finish();
        return true;

        default:
        return super.onOptionsItemSelected(item);
    }
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    com.actionbarsherlock.view.MenuInflater inflater = getSupportMenuInflater();
    inflater.inflate(R.menu.user_registration, (com.actionbarsherlock.view.Menu) menu);
    return super.onCreateOptionsMenu(menu);
}


@Override
public void onDisconnected() {
    Log.d(TAG, "disconnected");
}
@Override
protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
    if(requestCode == 2){
        if(responseCode ==RESULT_OK){
            if(intent.getExtras().containsKey("user_id")){
                String userId = intent.getExtras().getString("user_id");
                Intent returnIntent = new Intent();
                returnIntent.putExtra("user_id", userId);
                setResult(RESULT_OK,returnIntent);
                getSherlock().setProgressBarIndeterminateVisibility(true);
                finish();
                }else{
                getSherlock().setProgressBarIndeterminateVisibility(true);
            }
        }

    }else{
        Session.getActiveSession().onActivityResult(this, requestCode, responseCode, intent);
    }

}
private class SessionStatusCallback implements Session.StatusCallback {
    @Override
    public void call(Session session, SessionState state, Exception exception) {
        if(!TextUtils.isEmpty(session.getAccessToken())){
            SharedPreferences.Editor editor = settings.edit();
            editor.putString("user_token","@FB@:"+session.getAccessToken());
            editor.putString("user_token_type","FACEBOOK");
            // Commit the edits!
            editor.commit();

            new UserLoginService(_activity).execute("@FB@:"+session.getAccessToken());

        }
    }
}
public void onResultFromAsyncTask(User result) {
    if(result!=null){
        Intent returnIntent = new Intent();
        returnIntent.putExtra("user_id", result.getId());
        setResult(RESULT_OK,returnIntent);
        getSherlock().setProgressBarIndeterminateVisibility(true);
        finish();
    }
}

}

Answer 1

它并不是要求“电子邮件”权限，因为它始终是“else”情况，它使用空权限列表调用openActiveSession方法（默认情况下只获取“basic_info”）。

尝试将onClickLogin更改为：

Session session = Session.getActiveSession();
if (session == null) {
    session = new Session(this);
    Session.setActiveSession(session);
}
if (!session.isOpened() && !session.isClosed())) {
    session.openForRead(new Session.OpenRequest(this)
      .setPermissions(Arrays.asList("basic_info","email"))
      .setCallback(statusCallback));
}

Answer 2

请求电子邮件权限的更快方法是使用Session.openActiveSession（）调用的可选第三个参数，如下所示：

Session.openActiveSession(getActivity(), true, Arrays.asList("basic_info","email") ,new Session.StatusCallback() {...});

使用以下代码与您合作

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(YourActivity.this, false, new Session.StatusCallback() {

                      @Override
                      public void call(final Session session, SessionState state,
                              Exception exception) {

                          if (session.isOpened()) {

                              Request.executeMeRequestAsync(session,
