请求服务器身份验证代码时，GoogleSignInResult会在Android应用中返回DEVELOPER_ERROR

Question

我按照本手册将Google People API连接到Android应用：http://blog.iamsuleiman.com/people-api-android-tutorial-1/

我使用以下代码登录：

GoogleSignInOptions signInOptions = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
        .requestEmail()
        .requestScopes(new Scope(Scopes.PLUS_LOGIN),
                new Scope(PeopleScopes.CONTACTS_READONLY),
                new Scope(PeopleScopes.USER_PHONENUMBERS_READ))
        .requestServerAuthCode(getString(R.string.google_oauth_client_id), false)
        .build();

    mGoogleApiClient = new GoogleApiClient.Builder(getContext())
            .enableAutoManage(getActivity(), this)
            .addApi(Auth.GOOGLE_SIGN_IN_API, signInOptions)
            .build();

    Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent( mGoogleApiClient );
    startActivityForResult( signInIntent, GOOGLE_PLUS_RC_SIGN_IN );

onActivityResult代码是：

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
    ...
}

我不断得到DEVELOPER_ERROR。

该应用程序由我在开发人员控制台中设置的SHA1指纹代码签名。

OAUTH客户端ID取自我的应用程序的“Web客户端”JSON配置。

所有API均在Google开发人员控制台中启用

如果我删除方法.requestServerAuthCode（）：

    GoogleSignInOptions signInOptions = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .requestScopes(new Scope(Scopes.PLUS_LOGIN),
                    new Scope(PeopleScopes.CONTACTS_READONLY),
                    new Scope(PeopleScopes.USER_PHONENUMBERS_READ))
            .build();

的结果

Auth.GoogleSignInApi.getSignInResultFromIntent（数据）;

成功：该应用程序要求获得许可。

我做错了什么？

尽管在Google手册中有使用此方法的示例，为什么requestServerAuthCode会导致DEVELOPER_ERROR：

https://developers.google.com/identity/sign-in/android/offline-access#enable_server-side_api_access_for_your_app

有没有示例如何在Android应用中使用People API？

Answer 1

而不是将您的生产/调试client_id传递给

.requestServerAuthCode（）

方法使用Web client_id代替 - 我认为google signin将始终使用string.xml中的server_client_id。

所以从技术上讲，你需要使用两个键。

谷歌登录： -

     GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                    .requestEmail()
                    .build();

GoogleSignInClient mGoogleSignInClient = GoogleSignIn.getClient(this, gso); 

在您的btn点击调用此方法： -

private void signIn() {
        progressDialog(this, "Please wait...", true);
        Intent signInIntent = mGoogleSignInClient.getSignInIntent();
        startActivityForResult(signInIntent, RC_SIGN_IN);
    }

onActivityResult： -

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        progressDialog(this, "Please wait...", false);
        if (requestCode == RC_SIGN_IN) {

            try {
                // Google Sign In was successful, authenticate with Firebase
                Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
                handleSignInResult(task);
            } catch (Exception e) {
                // Google Sign In failed, update UI appropriately
                Log.w(TAG, "Google sign in failed", e);
                // ...
            }
        }
    }

最后保存您的详细信息： -

private void handleSignInResult(Task<GoogleSignInAccount> task) {
        try {
            GoogleSignInAccount account = task.getResult(ApiException.class);
            socialId = account.getId();
            socialName = account.getDisplayName();
            socialEmail = account.getEmail();
            //you have got all the details now you can go your next screen
        } catch (ApiException e) {
            Toast.makeText(this, "Authentication failed", Toast.LENGTH_SHORT).show();
        }
        mGoogleSignInClient.signOut();
    }
