c# - 谷歌 Oauth 错误 : 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 ID 是一个“服务帐户”。我下载了 json key 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，出现此错误:至少应设置一个客户端 secret (已安装或 Web)。

但是，在我的 json 中没有“客户端密码”:

{
  "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“服务帐户”？不知道...

使用 json 文件的解决方案非常相似。

这是使用 GoogleCredential 对象创建 VisionService 的示例，该对象通过 ServiceAccountCredential 从 json 文件创建。

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
