使用 Google+ API 获取用户凭据

Question

我正在尝试使用 Google+ [=32] 在我的 android 应用程序中包含 Google 登录 =]. 我可以从用户那里获取帐户详细信息，但是一旦登录，当 请求用户名 时，我得到 null使用电话：

Plus.PeopleApi.getCurrentPerson(mGoogleApiClient).getDisplayName()

并且Logcat显示：

BasicNetwork.performRequest: Unexpected response code 403 for https://www.googleapis.com/plus/v1/people/me

虽然我可以使用以下方式获取用户的电子邮件：

Plus.AccountApi.getAccountName(GoogleClient.mGoogleApiClient)

请帮助我发现我的错误

Answer 1

我认为 google+ 应用程序中登录集成的基本步骤已为 you.Here 所知，其余步骤为

第一步-- 在 oncreate

 mGoogleApiClient = new GoogleApiClient.Builder(this)
         .addConnectionCallbacks(this)
         .addOnConnectionFailedListener(this)
         .addApi(Plus.API)
         .addScope(Plus.SCOPE_PLUS_LOGIN)
         .build();

第2步-- 在登录按钮中单击侦听器调用此----

private void LoginGoogle(){
        int errorCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(context);
        if (errorCode != ConnectionResult.SUCCESS) {
          GooglePlayServicesUtil.getErrorDialog(errorCode, this, 0).show();
        }
        else{
            //perform login
            if (!mGoogleApiClient.isConnecting()) {
                mSignInClicked = true;
                mGoogleApiClient.connect();

            }
        }
    }

第3步---- 在 onActivityresult

if (requestCode == RC_SIGN_IN) { 
                if (resultCode != RESULT_OK) {
                  mSignInClicked = false;
            }

            mIntentInProgress = false;

            if (!mGoogleApiClient.isConnected()) {
              mGoogleApiClient.reconnect();
            }
          }

step 4-----

    @Override
    public void onConnectionFailed(ConnectionResult result) {
        // TODO Auto-generated method stub
        if(!mIntentInProgress){
            if ( mSignInClicked && result.hasResolution()) {
                 // The user has already clicked 'sign-in' so we attempt to resolve all
                  // errors until the user is signed in, or they cancel.
                  try {
                    result.startResolutionForResult(this, RC_SIGN_IN);
                    mIntentInProgress = true;
                  } catch (SendIntentException e) {
                    // The intent was canceled before it was sent.  Return to the default
                    // state and attempt to connect to get an updated ConnectionResult.
                    mIntentInProgress = false;
                    mGoogleApiClient.connect();
                  }

              }
        }
    }
    @Override
    public void onConnected(Bundle arg0) {
        // TODO Auto-generated method stub
        mSignInClicked = false;
        getProfileInformation();
    }
    @Override
    public void onConnectionSuspended(int arg0) {
        // TODO Auto-generated method stub
        mGoogleApiClient.connect();
    }


    @Override
    protected void onStop() {
        // TODO Auto-generated method stub
        super.onStop();
        if (mGoogleApiClient.isConnected()) {
              mGoogleApiClient.disconnect();
            }

    }

步骤 5-----

private void getProfileInformation(){
        try {
            if (Plus.PeopleApi.getCurrentPerson(mGoogleApiClient) != null) {
                Person currentPerson = Plus.PeopleApi.getCurrentPerson(mGoogleApiClient);
                String id=currentPerson.getId();
                String personName = currentPerson.getDisplayName();
                String personPhoto = currentPerson.getImage().getUrl();
                String email = Plus.AccountApi.getAccountName(mGoogleApiClient);

                String profilePic=personPhoto.substring(0,
                        personPhoto.length() - 2)
                        + ProfilePicSize;

                Log.e("GOOGLE", id);
                Log.e("GOOGLE", personName);
                Log.e("GOOGLE", profilePic);
                Log.e("GOOGLE",email);


              }

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

我已经尝试过相同的代码并且工作正常！ 所以，只要确保两件事：

1)在下面的 Google API Console.Link 中注册您的数字签名 .apk 文件的 public 证书：

https://developers.google.com/+/mobile/android/getting-started#step_1_enable_the_google_api

2)确保您已添加 google+ api 访问权限并使用 SHA1 创建了客户端密钥。
休息就好了。
