我正在尝试将文件上传到Google Cloud 端存储中的存储桶 .
我编写了以下代码来创建StorageService并将文件上传到存储桶 .
GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer() {
ClientSecrets = new ClientSecrets { ClientId = _googleSettings.ClientID, ClientSecret = _googleSettings.ClientSecret },
DataStore = new FileDataStore(System.Web.HttpContext.Current.Server.MapPath("/App_Data")),
Scopes = new string[] { StorageService.Scope.DevstorageReadWrite },
});
UserCredential userCredentials = new UserCredential(flow, Environment.UserName, new TokenResponse());
StorageService service = new StorageService(new BaseClientService.Initializer()
{
HttpClientInitializer = userCredentials,
ApplicationName = "GCS Sample"
});
Google.Apis.Storage.v1.Data.Object fileobj = new Google.Apis.Storage.v1.Data.Object() { Name = fileDetails.FileName };
ObjectsResource.InsertMediaUpload uploadService = service.Objects.Insert(fileobj, _googleSettings.BucketName, fileDetails.Stream, fileDetails.MimeContentType);
IUploadProgress progress = uploadService.Upload();
if (progress.Exception != null) //The exception always exists.
{
throw progress.Exception;
}
但是，调用upload方法时会抛出一个ArgumentNullException，表示“Value不能为null . 参数名：baseUri” .
有谁知道如何解决这个问题？

我也遇到了这个错误，这是因为我的流对象中有一个空格作为第一个字符 . 一旦我创建了非空格字符，上传就起作用了 . 正如Vaqar上面所说，这似乎是一个默认错误，所以不确定这个答案是否有帮助但可能会帮助其他人......
