Google Oauth error: At least one client secrets (Installed or Web) should be set

Question

我正在使用 Google 的 Oauth 2.0 通过我们的服务器将视频上传到 Youtube。我的客户端 ID 是 "service account"。我下载了 json 密钥并将其添加到我的解决方案中。

相关代码如下：

 private async Task Run(string filePath)
        {
            UserCredential credential;
            var keyUrl = System.Web.HttpContext.Current.Server.MapPath("~/content/oauth_key.json");
            using (var stream = new FileStream(keyUrl, FileMode.Open, FileAccess.Read))
            {
                credential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
                    GoogleClientSecrets.Load(stream).Secrets,
                    // This OAuth 2.0 access scope allows an application to upload files to the
                    // authenticated user's YouTube channel, but doesn't allow other types of access.
                    new[] { YouTubeService.Scope.YoutubeUpload },
                    "user",
                    CancellationToken.None
                );
            }

            var youtubeService = new YouTubeService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = Assembly.GetExecutingAssembly().GetName().Name
            });

当我运行它时，我收到此错误：至少应设置一个客户端机密（已安装或 Web）。

然而，在我的json中没有"client secret":

{
  "private_key_id": "9d98c06b3e730070806dcf8227578efd0ba9989b",
  "private_key": "-----BEGIN PRIVATE KEY-----\nMIICdQIBADANBgkqhk etc,
  "client_email": "546239405652-8igo05a5m8cutggehk3rk3hspjfm3t04@developer.gserviceaccount.com",
  "client_id": "546239405652-8igo05a5m8cutggehk3rk3hspjfm3t04.apps.googleusercontent.com",
  "type": "service_account"
}

所以我想我忽略了什么。也许我不能使用 "service account" ？不知道...

Answer 1

不是 C# 专家，但您似乎在尝试使用服务帐户来执行 OAuth2 网络服务器流程，这应该行不通。您可能想改用 ServiceAccountCredential。有关不同 Google OAuth2 流程的更多信息，请参阅 web server, service account 等的文档

Answer 2

我设法获得了一个服务帐户来处理 P12 文件，但想知道如何使用 JSON 文件，或者只是 JSON 文件中的值来创建证书.

获取代币

    private static String GetOAuthCredentialViaP12Key()
    {
        const string serviceAccountEmail = SERVICE_ACCOUNT_EMAIL;
        var certificate = new X509Certificate2(SERVICE_ACCOUNT_PKCS12_FILE_PATH, "notasecret", X509KeyStorageFlags.Exportable);

        var scope = DriveService.Scope.Drive + " https://spreadsheets.google.com/feeds";
        var credential = new ServiceAccountCredential( new ServiceAccountCredential.Initializer(serviceAccountEmail)
                                                       {
                                                            Scopes  = new[] { scope }
                                                       }.FromCertificate(certificate) );

        if (credential.RequestAccessTokenAsync(CancellationToken.None).Result == false)
        {

            return null;
        }

        return credential.Token.AccessToken;
    }

这就是我使用我得到的令牌的方式

        // Initialize the variables needed to make the request
        OAuth2Parameters parameters = new OAuth2Parameters {AccessToken = token};
        GOAuth2RequestFactory requestFactory = new GOAuth2RequestFactory(null, "MySpreadsheetIntegration-v1", parameters);
        SpreadsheetsService service = new SpreadsheetsService("MySpreadsheetIntegration-v1");
        service.RequestFactory = requestFactory;

Answer 3

使用 json 文件的解决方案非常相似。

这里是创建 VisionService 使用 GoogleCredential 对象创建 json 文件 ServiceAccountCredential.

的示例

GoogleCredential credential;
using (var stream = new FileStream(fileName, FileMode.Open, FileAccess.Read))
{
    credential = GoogleCredential.FromStream(stream)
        .CreateScoped(VisionService.Scope.CloudPlatform);
}

var service = new VisionService(new BaseClientService.Initializer()
{
    HttpClientInitializer = credential,
    ApplicationName = "my-app-name",
});

此示例需要两个 NuGet 包：

Google.Apis.Vision.v1  
Google.Apis.Oauth2.v2
