因此，我從此處復制了 Google Drive API .NET Quickstart (v3)中的代碼，代碼運行良好，按預期列出了我的 Google Drive 上的所有文件。但是，當我嘗試使用此處找到的上傳示例代碼時，我無法將本地存儲的圖像上傳到我的云端硬盤并request.ResponseBody返回null。我還添加了額外的驅動器范圍，但沒有幫助。為什么上傳文件的示例代碼不起作用？我的代碼如下：using Google.Apis.Auth.OAuth2;using Google.Apis.Drive.v3;using Google.Apis.Drive.v3.Data;using Google.Apis.Services;using Google.Apis.Util.Store;using System;using System.Collections.Generic;using System.Threading;using System.Windows;namespace Google_Drive_REST_App{ /// <summary> /// Interaction logic for MainWindow.xaml /// </summary> public partial class MainWindow : Window { static string[] Scopes = { DriveService.Scope.Drive, DriveService.Scope.DriveAppdata, DriveService.Scope.DriveFile, DriveService.Scope.DriveMetadataReadonly, DriveService.Scope.DriveReadonly, DriveService.Scope.DriveScripts}; static string ApplicationName = "Google Drive REST App"; UserCredential credential; DriveService service; public MainWindow() { InitializeComponent(); using (var stream = new System.IO.FileStream("credentials.json", System.IO.FileMode.Open, System.IO.FileAccess.ReadWrite)) { // The file token.json stores the user's access and refresh tokens, and is created // automatically when the authorization flow completes for the first time. string credPath = "token.json"; credential = GoogleWebAuthorizationBroker.AuthorizeAsync( GoogleClientSecrets.Load(stream).Secrets, Scopes, "user", CancellationToken.None, new FileDataStore(credPath, true)).Result; Console.WriteLine("Credential file saved to: " + credPath); }

我剛剛測試了以下代碼，它工作正常。我希望它能幫助你。
class Program
{
static void Main(string[] args)
{
var service = Oauth2Example.GetDriveService(@"C:\Users\linda\Documents\.credentials\NativeClient.json", "test",
new[] {Google.Apis.Drive.v3.DriveService.Scope.Drive});
var fileMetadata = new Google.Apis.Drive.v3.Data.File()
{
Name = "flag.jpg"
};
FilesResource.CreateMediaUpload request;
using (var stream = new System.IO.FileStream(@"C:\temp\flag.jpg", System.IO.FileMode.Open))
{
request = service.Files.Create(fileMetadata, stream, "image/jpeg");
request.Fields = "id";
request.Upload();
}
var file = request.ResponseBody;
Console.WriteLine("File ID: " + file.Id);
Console.ReadKey();
}
}

其他遇到云端硬盤上傳問題的人應該查看您上傳的異常，這將使您更好地了解實際問題。
示例代碼：
var progress = request.Upload();
if (progress.Exception != null)
{
//Log execption, or break here to debug
YourLoggingProvider.Log(progress.Exception.Message.ToString());
}
這就是我找到問題根源的方式。
