我正在尝试从其 Google Plus 帐户获取用户的信息，包括性别和年龄。由于这些字段可能是私有(private)的，我认为明确请求它们可以解决问题。然而，尽管登录对话框明确指出该应用程序请求查看您的完整出生日期，但我无法获得生日信息。

这些是我的范围(尝试了很多变化):

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
        //.requestScopes(new Scope(Scopes.PROFILE))
        //.requestScopes(new Scope(Scopes.PLUS_LOGIN))
        .requestScopes(new Scope("https://www.googleapis.com/auth/user.birthday.read"),
                new Scope("https://www.googleapis.com/auth/userinfo.profile"))
        //.requestProfile()
        .requestEmail()
        .build();

mGoogleApiClient = new GoogleApiClient.Builder(this)
        .enableAutoManage(this, this)
        .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
        .addApi(Plus.API)
        .addScope(new Scope(Scopes.PROFILE))
        .build();

在 onActivityResult 中使用已弃用的 getCurrentPerson 时，我得到空值:

if (requestCode == RC_SIGN_IN) {
    GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);

    if (mGoogleApiClient.hasConnectedApi(Plus.API)) {
        Person person  = Plus.PeopleApi.getCurrentPerson(mGoogleApiClient);
        if (person != null) {
            Log.i(TAG, person.getDisplayName());    //returns full name successfully
            Log.i(TAG, person.getGender());         //0
            Log.i(TAG, person.getBirthday());       //null
        }
    }
}

我也尝试从帐户 (GoogleSignInAccount account = result.getSignInAccount()) 获取它，但据我搜索，这个变量根本不拥有请求的数据。

我错过了什么吗？或者即使明确请求也无法获取私有(private)数据？

谢谢。

顺便说一句，我还没有尝试过使用私有(private)性别的场景。

最佳答案

我认为this Google People API documentation将对您的问题有所帮助。

请注意:

If the request requires authorization (such as a request for an individual's private data), then the application must provide an OAuth 2.0 token with the request. The application may also provide the API key, but it doesn't have to.

和

Requests to the People API for non-public user data must be authorized by an authenticated user.

...

5. If the user approves, then Google gives your application a short-lived access token.
6. Your application requests user data, attaching the access token to the request.
7. If Google determines that your request and the token are valid, it returns the requested data.

如果您的应用没有获得访问 token ，您可以阅读Using OAuth 2.0 to Access Google APIs或者试试我对以下问题的回答:

How to get access token after user is signed in from Gmail in Android?

更新:假设您的应用可以使用我上面回答中的示例代码获取访问 token ，然后在 onResponse 中添加更多代码段，如下所示:

...
@Override
public void onResponse(Response response) throws IOException {
    try {
        JSONObject jsonObject = new JSONObject(response.body().string());
        final String message = jsonObject.toString(5);
        Log.i("onResponse", message);

        // FROM HERE...
        String accessToken = jsonObject.optString("access_token");

        OkHttpClient client2 = new OkHttpClient();
        final Request request2 = new Request.Builder()
                .url("https://people.googleapis.com/v1/people/me")
                .addHeader("Authorization", "Bearer " + accessToken)
                .build();

        client2.newCall(request2).enqueue(new Callback() {
            @Override
            public void onFailure(final Request request, final IOException e) {
                Log.e("onFailure", e.toString());
            }

            @Override
            public void onResponse(Response response) throws IOException {
                try {
                    JSONObject jsonObject = new JSONObject(response.body().string());
                    final String message = jsonObject.toString(5);
                    Log.i("onResponse", message);
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        });
    } catch (JSONException e) {
        e.printStackTrace();
    }
}
...

Logcat 信息(我截断了它，因为它很长)

I/onResponse: {
                   "photos": [
                        {
                             "url": "https:...photo.jpg",
                             "metadata": {
                                  "source": {
                                       "id": "1....774",
                                       "type": "PROFILE"
                                  },
                                  "primary": true
                             }
                        }
                   ],
                   ...                                                                               
                   "birthdays": [
                        {
                             "date": {
                                  "month": 2,
                                  "year": 1980,
                                  "day": 2
                             },
                             "metadata": {
                                  "source": {
                                       "id": "1....774",
                                       "type": "PROFILE"
                                  },
                                  "primary": true
                             }
                        }
                   ],
                   ....
              }

GoogleSignInOptions 和 GoogleApiClient:

String serverClientId = getString(R.string.server_client_id);
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
        .requestScopes(new Scope("https://www.googleapis.com/auth/user.birthday.read"))
        .requestServerAuthCode(serverClientId)
        .build();

GoogleApiClient mGoogleApiClient = new GoogleApiClient.Builder(this)
        .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
        .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
        .build();

请注意，我在这里使用的 OkHttp 版本是 v2.6.0，如果您的应用程序使用最新的 (3.3.1)，则语法/类会有所不同。当然你也可以使用其他的比如Volley, Retrofit...
