c# - 是否可以使用 json key 而不是 p12 key 来获取服务帐户凭据？

Question

我在 C# 中使用“Google.Apis.Bigquery.v2 客户端库”。

我正在使用“服务帐户”授权 Google BigQuery(请参阅 http://www.afterlogic.com/mailbee-net/docs/OAuth2GoogleServiceAccounts.html)。要创建 X509 证书，我使用来自 Google Developers Console 的 p12 key 。但是，现在 json key 是默认值。我可以用它代替 p12 key 吗？

我有以下代码:

    string serviceAccountEmail = "xxxx@developer.gserviceaccount.com";

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();

现在可以(我使用的是 Google API 的 v 1.13.1.0)。

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);

Google 表格示例:

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;
