問題描述

是否有桌面應用程序如何授權 Google Drive 服務和上傳文件的代碼示例?

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

但是接下來的步驟是什么?正如我從示例中看到的那樣，我應該獲取 IAuthenticator 實例并將其傳遞給 DriveService 類的構造函數......如何獲取 IAuthenticator 的實例?如果我上面的代碼是正確的......提前致謝.

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.

這是一個完整的 C# 命令行示例，用于將文件上傳到 Google Drive:

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);
        }
    }
}
