C＃桌面应用程序。简单的例子，如何将文件上传到谷歌驱动器 [英] C# Desktop application. Simple example how to upload a file to Google Drive

问题描述

有一个桌面应用程序的任何code例如如何授权给谷歌云端硬盘服务，并上传图片？

Is there any code example of a desktop application how to authorize to Google Drive service and upload a file?

目前我有：

var parameters = new OAuth2Parameters
                                 {
                                     ClientId = ClientCredentials.ClientId,
                                     ClientSecret = ClientCredentials.ClientSecret,
                                     RedirectUri = ClientCredentials.RedirectUris[0],
                                     Scope = ClientCredentials.GetScopes()
                                 };    
string url = OAuthUtil.CreateOAuth2AuthorizationUrl(parameters);
    // Open url, click to allow and copy secret code
    parameters.AccessCode = secretCodeFromBrowser;
    OAuthUtil.GetAccessToken(parameters);
    string accessToken = parameters.AccessToken;
    // So, there is the access token

但什么是下一个步骤？当我从实例看，我应该得到IAuthenticator实例，并将其传递到DriveService类的构造函数......如何获得IAuthenticator的实例？如果我的上述code是正确的？
先谢谢了。

But what are the next steps? As I see from examples I should get IAuthenticator instance and pass it into constructor of DriveService class... How to get an instance of IAuthenticator? If my above code is correct... Thanks in advance.

下面是在C＃一个完整的命令行样本文件上传到谷歌驱动器：

Here is a complete command-line sample in C# to upload a file to Google Drive:

using System;
using System.Diagnostics;
using DotNetOpenAuth.OAuth2;
using Google.Apis.Authentication.OAuth2;
using Google.Apis.Authentication.OAuth2.DotNetOpenAuth;
using Google.Apis.Drive.v2;
using Google.Apis.Drive.v2.Data;
using Google.Apis.Util;

namespace GoogleDriveSamples
{
    class DriveCommandLineSample
    {
        static void Main(string[] args)
        {
            String CLIENT_ID = "YOUR_CLIENT_ID";
            String CLIENT_SECRET = "YOUR_CLIENT_SECRET";

            // Register the authenticator and create the service
            var provider = new NativeApplicationClient(GoogleAuthenticationServer.Description, CLIENT_ID, CLIENT_SECRET);
            var auth = new OAuth2Authenticator<NativeApplicationClient>(provider, GetAuthorization);
            {
                Authenticator = auth
            });

            File body = new File();
            body.Title = "My document";
            body.Description = "A test document";
            body.MimeType = "text/plain";

            byte[] byteArray = System.IO.File.ReadAllBytes("document.txt");
            System.IO.MemoryStream stream = new System.IO.MemoryStream(byteArray);

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

            File file = request.ResponseBody;
            Console.WriteLine("File id: " + file.Id);
            Console.ReadLine();
        }

        private static IAuthorizationState GetAuthorization(NativeApplicationClient arg)
        {
            // Get the auth URL:
            IAuthorizationState state = new AuthorizationState(new[] { DriveService.Scopes.Drive.GetStringValue() });
            state.Callback = new Uri(NativeApplicationClient.OutOfBandCallbackUrl);
            Uri authUri = arg.RequestUserAuthorization(state);

            // Request authorization from the user (by opening a browser window):
            Process.Start(authUri.ToString());
            Console.Write("  Authorization Code: ");
            string authCode = Console.ReadLine();
            Console.WriteLine();

            // Retrieve the access token by using the authorization code:
            return arg.ProcessUserAuthorization(authCode, state);
        }
    }
}
