Firebase Google身份验证：提供的身份验证凭证格式错误或已过期

Question

我尝试使用Firebase设置Google Auth，但得到：

{
  "code": "auth/invalid-credential",
  "message": "The supplied auth credential is malformed or has expired."
}

在“网络”标签中，我注意到了

{
  "error": {
    "code": 400,
    "message": "INVALID_IDP_RESPONSE : Error getting access token from google.com, OAuth2 redirect uri is: https://....firebaseapp.com/__/auth/handler, response: OAuth2TokenResponse{params: error=invalid_client&error_description=Unauthorized, httpMetadata: HttpMetadata{status=401, cachePolicy=NO_CACHE, cacheDuration=null, cacheImmutable=false, staleWhileRevalidate=null, filename=null, lastModified=null, headers=HTTP/1.1 200 OK\r\n\r\n, contentSecurityPolicies=[], cookieList=[]}}",
    "errors": [
      {
        "message": "INVALID_IDP_RESPONSE : Error getting access token from google.com, OAuth2 redirect uri is: https://....firebaseapp.com/__/auth/handler, response: OAuth2TokenResponse{params: error=invalid_client&error_description=Unauthorized, httpMetadata: HttpMetadata{status=401, cachePolicy=NO_CACHE, cacheDuration=null, cacheImmutable=false, staleWhileRevalidate=null, filename=null, lastModified=null, headers=HTTP/1.1 200 OK\r\n\r\n, contentSecurityPolicies=[], cookieList=[]}}",
        "domain": "global",
        "reason": "invalid"
      }
    ]
  }
}

此刻我正在localhost上进行测试，如何使它起作用？在授权域下，我已经看到了localhost。怎么了？
