Question

我正在使用bigquery进行身份验证。

我已经构建了一个身份验证密钥，例如“https://console.developers.google.com/apis/credentials?project= ...” - OAuth 2.0客户端ID，

我正在使用visual studio 2015，并从nuget安装：googles.apis.bigQuery.v2。

另外，我在包管理器控制台中写道：Install-Package Google.Cloud.BigQuery.V2 -Pre

我正在尝试连接到bigquery - 我成功了，但是当我创建凭据时，系统会提示我登录gmail帐户+接受一些范围访问权限。

我不想提示。

另外 - 在我的代码中，当使用凭据登录时 - 即使我的凭据不正确，我也成功连接到项目。

这是我的代码：

                projectId = "myproject";

            string[] scopes = new string[] { BigqueryService.Scope.Bigquery,                // view and manage your BigQuery data
                                 BigqueryService.Scope.BigqueryInsertdata ,     // Insert Data into Big query
                                 BigqueryService.Scope.CloudPlatform,           // view and manage your data acroos cloud platform services
                                 BigqueryService.Scope.DevstorageFullControl,   // manage your data on Cloud platform services
                                 BigqueryService.Scope.DevstorageReadOnly ,     // view your data on cloud platform servies
                                 BigqueryService.Scope.DevstorageReadWrite };
            using (var stream = new FileStream("clientsecret.json", FileMode.Open, FileAccess.Read))
            {
                ClientSecrets cs = GoogleClientSecrets.Load(stream).Secrets;

                GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
                {

                    ClientSecrets = cs,
                    Scopes = scopes,
                    DataStore = new FileDataStore("Store")
                });
                UserCredential credentail;
                credentail = GoogleWebAuthorizationBroker.AuthorizeAsync(
                    cs,
                    scopes
                    , "username"
                    , CancellationToken.None
                    , new FileDataStore("Store")).Result; 
                    // ***** Here the Chrome explorer is opened, and I asked to login to gmail etc...
                    // Nevertheless, I
                    // ... rest of code.
            }

这是json文件：clientsecret.json

{
 "installed": {
"client_id": "xxx",
"project_id": "xxx",
"auth_uri": "https://accounts.google.com/o/oauth2/auth",
"token_uri": "https://accounts.google.com/o/oauth2/token",
"auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
"client_secret": "xxx",
"redirect_uris": [ "urn:ietf:wg:oauth:2.0:oob", "http://localhost" ]
}
}

我尝试过使用flow并添加凭证，如下所示：

            GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
            {

                ClientSecrets = cs,
                Scopes = scopes,
                DataStore = new FileDataStore("Store")
            });

                TokenResponse tokenResponse = null;
                //                    tokenResponse = new TokenResponse { RefreshToken = "120" , ExpiresInSeconds = 0};
                tokenResponse = new TokenResponse { RefreshToken = "120",  ExpiresInSeconds = -1};
  ...
  credentail = new UserCredential(flow, "Spotoption-BG-other", tokenResponse);

以上是以前的凭据设置而不是之前的凭据设置。当我尝试检索数据时：

string query = "select ...";
JobsResource j = Service.Jobs;
QueryRequest qr = new QueryRequest();
QueryResponse response = j.Query(qr, projectId).Execute();

我在最后一行遇到异常：附加信息：错误：“invalid_grant”，描述：“”，Uri：“”

当我这样做时：

bool b = flow.ShouldForceTokenRetrieval();

我得到了：假。

当tokenResponse = null时，我得到了消息（在QueryResponse response =之后）：

附加信息：对象引用未设置为的实例对象

要在没有浏览器提示的情况下使用Google身份验证，您必须使用令牌。

首次接受范围时会返回令牌，之后您可以保留该令牌并将其发送回google-api以供第二次使用。

刷新令牌对用户来说是永久性的。

以下是第一次检索令牌的代码（浏览器正在打开以接受范围的条款）：

=IF((WEEKNUM(D4,16)-13)<=0,(WEEKNUM(D4,16)-13)+53,WEEKNUM(D4,16)-13)

检索令牌后，可以按照我在示例中给出的流程发送它：

        public TokenResponse GetToken()
    {
        UserCredential credentail;

        try
        {
            string[] scopes = new string[] { BigqueryService.Scope.Bigquery,    // view and manage your BigQuery data
                                BigqueryService.Scope.BigqueryInsertdata ,  // Insert Data into Big query
                                BigqueryService.Scope.CloudPlatform,        // view and manage your data acroos cloud platform services
                                BigqueryService.Scope.DevstorageFullControl,// manage your data on Cloud platform services
                                BigqueryService.Scope.DevstorageReadOnly ,  // view your data on cloud platform servies
                                BigqueryService.Scope.DevstorageReadWrite };


            credentail = GoogleWebAuthorizationBroker.AuthorizeAsync(
                _clientSecret,
                scopes,
                "reports"
                , CancellationToken.None
                , new FileDataStore("Store")
                ).Result;
            if (credentail != null)
                return credentail.Token;
            else
            {
                _log.WriteToAll("Invalid credentials", EventLogEntryType.Error);
                return null;
            }
        }
        catch (Exception ex)
        {
            _log.WriteToAll(ex);
            return null;
        }
    }

BigQuery使用身份验证而无需浏览器提示
