如何使服务器对Google云端硬盘Api进行服务器身份验证? [英] How can I make a server to server authentication to Google Drive Api?

问题描述

我正在尝试对.Net Framework中的Google Drive Api进行服务器到服务器的身份验证.

I'm trying to make a server to server authentication to Google Drive Api in .Net Framework.

我看到了许多使用用户身份验证的示例，但是有一些服务器到服务器.

I saw many examples with user authentication, but a few server to server.

我看到有一个 C#中的Google Api库，但是我不知道怎么用

I saw that there is this Google Api library in C#, but I don't know how to use it.

有人可以帮助我吗?

推荐答案

下面是一个示例，在.Net Framework中将MVC与 Google云端硬盘API v3

Here is an example, using MVC in .Net Framework with API Client Library and Google Drive API v3

using System;
using System.Collections.Generic;
using System.IO;
using System.Web.Mvc;
using Google.Apis.Auth.OAuth2;
using Google.Apis.Drive.v3;
using Google.Apis.Services;
using static Google.Apis.Drive.v3.DriveService;

namespace TestApiGoogle.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult GoogleAuth()
        {
            FileStream fsSource = new FileStream
                (@"Path\secret_info.json", FileMode.Open, FileAccess.Read);

            string[] Scopes = { Scope.Drive };
            string ApplicationName = "Your app name";

            GoogleCredential credential = GoogleCredential.FromStream(fsSource)
                .CreateScoped(Scopes);

            // Create Drive API service.
            var service = new DriveService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = ApplicationName,
            });

            // Define parameters of request.
            FilesResource.ListRequest listRequest = service.Files.List();
            listRequest.PageSize = 10;
            listRequest.Fields = "nextPageToken, files(id, name)";

            // List files.
            IList<Google.Apis.Drive.v3.Data.File> files = listRequest.Execute()
                .Files;

            if (files != null && files.Count > 0)
            {
                foreach (var file in files)
                {
                    Console.WriteLine("{0} ({1})", file.Name, file.Id);
                }
            }
            else
            {
                Console.WriteLine("No files found.");
            }

            var jsonObject = new
            {
                files
            };

            return Json(jsonObject, JsonRequestBehavior.AllowGet);
        }
    }
}
