我当前正在将旧的Google加上登录代码转换为新方法。我发现很难理解基本原则。而且它不起作用。
第一步是解释如何在工作中签名：https://developers.google.com/Indentity/sign-in/android/sign-in
第二步是firebase。由于某些原因，您需要将上述文档与以下内容相结合：https://firebase.google.com/docs/auth/android/google-signin
为什么那是那样？它的目的似乎太复杂了：签署。反正。您必须执行以下操作：
在您的活动的onCreate中，您需要添加：
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(webClientId)
.build();
mGoogleApiClient = new GoogleApiClient.Builder(mActivity)
.enableAutoManage(mContext /* FragmentActivity */, this /* OnConnectionFailedListener */)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
mAuth = FirebaseAuth.getInstance();
在您的登录单击处理程序中，您添加
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
mActivity.startActivityForResult(signInIntent, RC_SIGN_IN);
在onActivityResult中，您必须添加
if (requestCode == RC_SIGN_IN) {
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
AuthCredential credential = GoogleAuthProvider.getCredential(result.getSignInAccount().getIdToken(), null);
mAuth.signInWithCredential(credential)
.addOnCompleteListener(mActivity, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
//do something
}
});
}
在这里，我在与getIdToken致电GoogleAuthProvider.getcredential时会得到一个例外。
com.google.firebase.firebaseexception：发生了内部错误。[无效的IDP响应：不允许与此应用程序一起使用Google ID_Token。
只是用
打印出令牌result.getSignInAccount（）。 工作正常。
我几乎确定此web_client_id是正确的，因为当我替换它时，初始登录请求将失败。
我在Auth-> Google-> Web SDK配置下检查了Firebase控制台。WebClient-ID和Secret匹配Google Console WebApp客户端ID中的WebClient-ID。
有人知道如何解决这个问题吗？
好的，在花了几个小时后，我决定摆脱所有相关的与firebase相关的东西。现在起作用。不明白为什么您都需要那个火池的东西。
用于登录我有以下内容：
在您的活动或活动范围中添加：
private static Activity mActivity;
private FragmentActivity mContext;
private GoogleApiClient mGoogleApiClient;
private GoogleSignInResult cachedSignInResult;
private String webClientId = "XXXXXXXXXXXX-xxxxxxxxxxxxxxx.apps.googleusercontent.com";
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(webClientId)
.build();
mGoogleApiClient = new GoogleApiClient.Builder(mActivity)
.enableAutoManage(mContext /* FragmentActivity */, this /* OnConnectionFailedListener */)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
}
添加用于处理登录请求的逻辑。
public void requestLogin(OnLoginCompleteListener onLoginCompleteListener) {
Log.d(TAG,"request login");
//already logged in scenarios
if (isConnected() && cachedSignInResult != null){
Log.d(TAG,"you are already logged in with "+cachedSignInResult.getDisplayName());
onLoginCompleteListener.onLoginSuccess()
return;
}
else if (isConnected()){
Log.d(TAG,"already connected, but no ");
silentLogin(onLoginCompleteListener);
return;
}
forceRegularLogin(onLoginCompleteListener);
}
public boolean isConnected() {
if (mGoogleApiClient == null){
Log.d(TAG,"cannot check isConnected without api client");
return false;
}
return mGoogleApiClient.isConnecting() || mGoogleApiClient.isConnected();
}
private void silentLogin(final OnLoginCompleteListener onLoginCompleteListener){
OptionalPendingResult<GoogleSignInResult> pendingResult =
Auth.GoogleSignInApi.silentSignIn(mGoogleApiClient);
pendingResult.setResultCallback(new ResultCallback<GoogleSignInResult>() {
@Override
public void onResult(@NonNull GoogleSignInResult googleSignInResult) {
if (googleSignInResult.isSuccess()){
Log.d(TAG,"result is ok with name "+googleSignInResult.getSignInAccount().getDisplayName());
cachedSignInResult = googleSignInResult;
onLoginCompleteListener.onLoginSuccess()
}
else{
Log.d(TAG,"not logged in silently. do regular login");
requestLogin(onLoginCompleteListener);
}
}
});
}
private void forceRegularLogin(OnLoginCompleteListener onLoginCompleteListener){
if (mGoogleApiClient == null){
Log.d(TAG,"cannot login in. no google api client");
onLoginCompleteListener.error("no_google_api_client_found");
return;
}
registeredLoginCallback = onLoginCompleteListener; //register for later use in activity result
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
mActivity.startActivityForResult(signInIntent, RC_SIGN_IN);
}
添加onActivityResult回调。
public void onActivityResult(int requestCode, int resultCode, Intent data) {
Log.d(TAG,"on activity result");
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
if (result.isSuccess()){
if (registeredLoginCallback != null) {
registeredLoginCallback.onLoginSuccess();
}
else{
Log.e(TAG,"no callback registered for logging in result ok");
}
}
else{
if (registeredLoginCallback != null) {
registeredLoginCallback.error();
}
else{
Log.e(TAG,"no callback registered for logging in result error");
}
}
}
添加接口以进行完整回调
public interface OnLoginCompleteListener{
public void onLoginSuccess();
public void error(String message);
}
现在在您的登录按钮回调中您添加
requestLogin(new OnLoginCompleteListener() {
@Override
public void onLoginSuccess() {
Log.d(TAG,"logged in");
}
@Override
public void error(String message) {
Log.d(TAG,"error logging in"+message);
}
}
此外，您可以添加以下方法和接口以获取用户配置文件信息
public void requestCurrentPerson(final OnRequestSocialPersonCompleteListener onRequestSocialPersonCompleteListener) {
Log.d(TAG,"request current person");
silentLogin(new OnLoginCompleteListener() {
@Override
public void onLoginSuccess(i) {
SocialPerson socialPerson = new SocialPerson();
socialPerson.id = signInResult.getSignInAccount().getId();
socialPerson.name = signInResult.getSignInAccount().getDisplayName();
socialPerson.avatarURL = signInResult.getSignInAccount().getPhotoUrl().toString();
onRequestSocialPersonCompleteListener.onRequestSocialPersonSuccess(socialPerson);
}
@Override
public void error(String message) {
onRequestSocialPersonCompleteListener.error("error_fetching_social_person "+message);
}
});
}
public interface OnRequestSocialPersonCompleteListener {
public void onRequestSocialPersonSuccess(SocialPerson socialPerson);
public void error(String message);
}
登录后，您会致电
requestCurrentPerson(new OnRequestSocialPersonCompleteListener() {
@Override
public void onRequestSocialPersonSuccess( SocialPerson socialPerson) {
Log.d(TAG,"this is my persoin "+socialPerson);
}
@Override
public void error(Message message) {
Log.d(TAG,"error_fetching_social_person " +message);
}
}
