我正在尝试将 facebook 登录集成到我的 android 应用程序中。现在我在 Parse Backend 中得到一个关于已登录用户的新行，其中包含他的真实姓名、他的用户名中的一些奇怪的值（例如：SnvvKEsIv6tX7 ...），以及一个 authData，它是 Json 并包含以下值：access_token、到期日期，身份证。
调试后我得到了 json 响应的 url，它只包含两个值，名称和 id，但是我这样声明列表： List permissions = Arrays.asList("public_profile", "email");
所以现在图表只返回两个值，我认为这是由于权限，但正如我所说我确实声明了。这是我的代码：
public class LoginActivity extends Activity {
private Dialog progressDialog;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
FacebookSdk.sdkInitialize(getApplicationContext());
ParseFacebookUtils.initialize(this);
// Check if there is a currently logged in user
// and it's linked to a Facebook account.
ParseUser currentUser = ParseUser.getCurrentUser();
if ((currentUser != null) && ParseFacebookUtils.isLinked(currentUser)) {
// Go to the user info activity
showUserDetailsActivity();
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
ParseFacebookUtils.onActivityResult(requestCode, resultCode, data);
}
public void onLoginClick(View v) {
progressDialog = ProgressDialog.show(LoginActivity.this, "", "Logging in...", true);
List<String> permissions = Arrays.asList("public_profile", "email");
// NOTE: for extended permissions, like "user_about_me", your app must be reviewed by the Facebook team
// (https://developers.facebook.com/docs/facebook-login/permissions/)
ParseFacebookUtils.logInWithReadPermissionsInBackground(this, permissions, new LogInCallback() {
@Override
public void done(ParseUser user, ParseException err) {
progressDialog.dismiss();
if (user == null) {
Log.d("TAG", "Uh oh. The user cancelled the Facebook login.");
} else if (user.isNew()) {
GraphRequest.newMeRequest(AccessToken.getCurrentAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject fbUser,
GraphResponse response) {
/*

* Facebook user's name, let's set it on the
* fullName field.
*/
Log.e("facebook User", fbUser.toString());
final ParseUser parseUser = ParseUser
.getCurrentUser();
if (fbUser != null
&& parseUser != null

parseUser.put("name",

我正在使用 Parse 1.9.4 和 ParseFacebookUtils 1.9.4。
