是否可以对服务帐户凭据使用json密钥而不是p12密钥？

Question

我正在使用C#的“Google. Apis. Bigquery. v2客户端库”。

我授权使用“服务帐户”搜索BigQuery（请参阅http://www.afterlogic.com/mailbee-net/docs/OAuth2GoogleServiceAccounts.html). 要创建X509证书，我使用Google开发者控制台中的p12密钥。然而，现在json键是默认的。我可以用它来代替p12键吗？

我有以下代码：

    string serviceAccountEmail = "[e-mail]";

X509Certificate2 certificate;
using (Stream stream = new FileStream(@"C:\key.p12", FileMode.Open, FileAccess.Read, FileShare.Read))
{
    using (MemoryStream ms = new MemoryStream())
    {
        stream.CopyTo(ms);
        certificate = new X509Certificate2(ms.ToArray(), "notasecret", X509KeyStorageFlags.Exportable);
    }
}

// Create credentials
ServiceAccountCredential credential = new ServiceAccountCredential(
    new ServiceAccountCredential.Initializer(serviceAccountEmail)
    {
        Scopes = new[] {
        BigqueryService.Scope.Bigquery,
        BigqueryService.Scope.CloudPlatform,
    },
    }.FromCertificate(certificate));

// Create the service
BaseClientService.Initializer initializer = new BaseClientService.Initializer()
{
    HttpClientInitializer = credential,
    ApplicationName = "My Application",
    GZipEnabled = true,
};

BigqueryService service = new BigqueryService(initializer);
var projects = service.Projects.List().Execute();

Answer 1

这对我有用：

var scopes = new[] { DriveService.Scope.Drive };

ServiceAccountCredential credential;
using (Stream stream = new FileStream(@"C:\path\key.json", FileMode.Open, FileAccess.Read, FileShare.Read))
{
    credential =
        GoogleCredential.FromStream(stream).CreateScoped(scopes).UnderlyingCredential as
            ServiceAccountCredential;
}

显然，您将为范围变量和密钥文件的路径提供自己的值。您还需要获取Google. Apis. Auth. OAuth2Nuget包以及您计划使用凭据的任何其他特定于服务的包（在我的例子中是Google. Apis. Drive. v3）。

我得到了这个链接，它表明在C#应用程序中使用JSON文件的服务帐户身份验证尚未添加到Google BigQuery API中。

Answer 3

现在这是可能的（我使用了Google API的1.13.1.0版）。

BigQuery示例：

GoogleCredential credential;
using (Stream stream = new FileStream(@"C:\mykey.json", FileMode.Open, FileAccess.Read, FileShare.Read))
{
    credential = GoogleCredential.FromStream(stream);
}

string[] scopes = new string[] {
    BigqueryService.Scope.Bigquery,
    BigqueryService.Scope.CloudPlatform, 
};
credential = credential.CreateScoped(scopes);

BaseClientService.Initializer initializer = new BaseClientService.Initializer()
{
    HttpClientInitializer = (IConfigurableHttpClientInitializer)credential,
    ApplicationName = "My Application",
    GZipEnabled = true,
};
BigqueryService service = new BigqueryService(initializer);

谷歌工作表示例：

GoogleCredential credential;
using (Stream stream = new FileStream(@"mykey.json", FileMode.Open, FileAccess.Read, FileShare.Read))
{
    credential = GoogleCredential.FromStream(stream);
}
credential = credential.CreateScoped(new[] { 
    "https://spreadsheets.google.com/feeds", 
    "https://docs.google.com/feeds" });

string bearer;
try
{
    Task<string> task = ((ITokenAccess)credential).GetAccessTokenForRequestAsync();
    task.Wait();
    bearer = task.Result;
}
catch (AggregateException ex)
{
    throw ex.InnerException;
}

GDataRequestFactory requestFactory = new GDataRequestFactory("My Application");
requestFactory.CustomHeaders.Add(string.Format(CultureInfo.InvariantCulture, "Authorization: Bearer {0}", bearer));

SpreadsheetsService service = new SpreadsheetsService("My Application");
service.RequestFactory = requestFactory;
