Question

我正在编写一个小型桌面应用，将文件上传到谷歌硬盘。所以当我登录我的Google帐户时一切正常，但是当我没有，程序会在此页面上引发浏览器＆＃34; https://accounts.google.com/ServiceLogin＆＃34;。我使用此代码：

        ClientSecrets secret = new ClientSecrets();
        secret.ClientId = "my_client_id";
        secret.ClientSecret = "my_client_secret";
        UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(secret, new[] { DriveService.Scope.Drive }, "user", CancellationToken.None).Result;

        var service = new DriveService(new BaseClientService.Initializer() { HttpClientInitializer = credential, ApplicationName = "TestUpload" });

        File body = new File();
        body.Title = "Title123";
        body.Description = "Decription123";
        body.MimeType = "image/png";

        byte[] arr = System.IO.File.ReadAllBytes(fileName);
        System.IO.MemoryStream stream = new System.IO.MemoryStream(arr);

        FilesResource.InsertMediaUpload request = service.Files.Insert(body, stream, "image/png");
        request.Upload();

那么如何以编程方式授权而无需提升浏览器？

您的大多数问题是您没有保存身份验证。您正在请求访问但不保存。在以下示例中，fileDataStore将身份验证信息以％AppData％的形式存储在您的计算机上的文件中，这样下次运行程序时将不需要身份验证，并且它也不会要求您当时登录Google。

//Scopes for use with the Google Drive API
string[] scopes = new string[] { DriveService.Scope.Drive,
                                 DriveService.Scope.DriveFile};
// here is where we Request the user to give us access, or use the Refresh Token that was previously stored in %AppData%
UserCredential credential = 
            GoogleWebAuthorizationBroker
                          .AuthorizeAsync(new ClientSecrets { ClientId = CLIENT_ID
                                                            , ClientSecret = CLIENT_SECRET }
                                          ,scopes
                                          ,Environment.UserName
                                          ,CancellationToken.None
                                          ,new FileDataStore("Daimto.GoogleDrive.Auth.Store")
                                          ).Result;
DriveService service = new DriveService(new BaseClientService.Initializer()
 {
 HttpClientInitializer = credential,
 ApplicationName = "Drive API Sample",
 });

 public static File uploadFile(DriveService _service, string _uploadFile, string _parent) {

            if (System.IO.File.Exists(_uploadFile))
            {
                File body = new File();
                body.Title = System.IO.Path.GetFileName(_uploadFile);
                body.Description = "File uploaded by Diamto Drive Sample";
                body.MimeType = GetMimeType(_uploadFile);
                body.Parents = new List<ParentReference>() { new ParentReference() { Id = _parent } };

                // File's content.
                byte[] byteArray = System.IO.File.ReadAllBytes(_uploadFile);
                System.IO.MemoryStream stream = new System.IO.MemoryStream(byteArray);
                try
                {
                    FilesResource.InsertMediaUpload request = _service.Files.Insert(body, stream, GetMimeType(_uploadFile));
                    request.Upload();
                    return request.ResponseBody;
                }
                catch (Exception e)
                {
                    Console.WriteLine("An error occurred: " + e.Message);
                    return null;
                }
            }
            else {
                Console.WriteLine("File does not exist: " + _uploadFile);
                return null;
            }           

        }

这段代码是从Google Drive C# upload教程中删除的，如果你想了解更多关于它的作用及其工作原理的信息，你可能需要检查一下。 GitHub上的Google-Dotnet-Samples项目中还有一个可用的Sample项目。本教程基于该示例项目。
