使用服务帐户将文件上传到谷歌商家中心生成的谷歌云存储桶中

我能够用以下代码将文件上传到Google云存储桶。我手动创建了bucket。

        String serviceAccountEmail = "xxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx@developer.gserviceaccount.com";
        var certificate = new X509Certificate2(@"C:'...'projectname-xxxxxxxxxxxx.p12", "notasecret", X509KeyStorageFlags.Exportable);
        var scopes = new[] { @"https://www.googleapis.com/auth/devstorage.full_control" };
        ServiceAccountCredential credential = new ServiceAccountCredential(
            new ServiceAccountCredential.Initializer(serviceAccountEmail)
            {
                Scopes = scopes
            }.FromCertificate(certificate));
        StorageService service = new StorageService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
            ApplicationName = "Shipment Feed",
        });
        var bucketToUpload = "bucket-created-by-me";
        var newObject = new Google.Apis.Storage.v1.Data.Object()
        {
            Bucket = bucketToUpload,
            Name = "ShipmentFeed.txt"
        };

        FileStream fileStream = null;
        var path = @"C:'...'file.txt";
        fileStream = new FileStream(path, FileMode.Open);
        var uploadRequest = new ObjectsResource.InsertMediaUpload(service, newObject,
           bucketToUpload, fileStream, "text/plain");
        uploadRequest.Upload();

现在，当我试图将文件上传到由Google Merchant Center为同一个Google帐户生成的bucket时，我遇到了这个问题。我使用了上面的代码，只需将bucket名称从设置->谷歌云存储更改为谷歌商家中心提供的值

var bucketToUpload = "merchantxxxxxxx";

此过程没有将文件上传到bucket（使用gsutil测试-bucket在我的项目中存在，但为空）。为什么我不能上传文件？

您的代码未授权访问Google云存储。创建ServiceAccountCredential后，必须通过调用获取访问令牌

 ServiceAccountCredential sac = new ServiceAccountCredential(
            new ServiceAccountCredential.Initializer(serviceAccountEmail)
            {
                Scopes = scopes
            }.FromCertificate(certificate));
 var cts = new CancellationToken();
 var response = sac.RequestAccessTokenAsync(cts).Result;

如果响应为true，您的ServiceAccountCredential对象将设置ServiceAccountCreential.Token.AccessToken。

然后，当您创建上传请求时，您必须提供您获得的AccessToken：

var uploadRequest = new ObjectsResource.InsertMediaUpload(service, newObject,
       bucketToUpload, fileStream, "text/plain");
uploadRequest.OauthToken = sac.Token.AccessToken;

最后呼叫：

uploadRequest.Upload();
