谷歌云端硬盘校验和

Question

我可以通过 Drive API 检索校验和吗？

This answer 通过文档中的“试用”功能进行操作，该功能的界面很糟糕。

我如何通过 .NET (C#) Google Drive API 来做到这一点？ 或者，我如何使用自己的发布/获取请求来做到这一点？

试试.NET Quickstart，因为它是一种基本的列表文件方法。

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.IO;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;

namespace DriveQuickstart
{
    class Program
    {
        // If modifying these scopes, delete your previously saved credentials
        // at ~/.credentials/drive-dotnet-quickstart.json
        static string[] Scopes = {  DriveService.Scope.DriveReadonly };
        static string ApplicationName = "Drive API .NET Quickstart";

        static void Main(string[] args)
        {
            UserCredential credential;

            using (var stream =
                new FileStream("client_secret.json", FileMode.Open, FileAccess.Read))
            {
                string credPath = System.Environment.GetFolderPath(
                    System.Environment.SpecialFolder.Personal);
                credPath = Path.Combine(credPath, ".credentials/drive-dotnet-quickstart.json");

                credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                    GoogleClientSecrets.Load(stream).Secrets,
                    Scopes,
                    "user",
                    CancellationToken.None,
                    new FileDataStore(credPath, true)).Result;
                Console.WriteLine("Credential file saved to: " + credPath);
            }

            // 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;
            Console.WriteLine("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.");
            }
            Console.Read();

        }
    }
}

    }
}

编辑这一行：

listRequest.Fields = "nextPageToken, files(id, name)";

收件人：

listRequest.Fields = "nextPageToken, files(id, name, md5Checksum)";

上面链接的解决方案是正确的，Try it 功能将帮助您熟悉每种方法以及响应和请求是如何形成的。

希望这会有所帮助。
