Question

您好

我正在尝试在特定用户帐户下创建文件。
用户帐户位于我的Google域中。
对于Oauth我正在使用服务帐户。

DriveService（）

private static DriveService Service()
    {
        var certificate = new X509Certificate2(Constants.P12, "notasecret", X509KeyStorageFlags.Exportable);
        var credential = new ServiceAccountCredential(
           new ServiceAccountCredential.Initializer(Constants.ServiceAccountEmail)
           {
               Scopes = new[] {
                   DriveService.Scope.Drive,
               }
           }.FromCertificate(certificate));

        // Create the service.
        var service = new DriveService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
            ApplicationName = "MyApplicationName",
        });

        return service;
    }

创建文件

private static void CreateDriveDocument(string title)
    {
        Console.WriteLine("Google - Create New Document:" + Environment.NewLine);
        File body = new File();
        body.Title = title;
        body.Description = "A test document";
        body.MimeType = "text/plain";
        byte[] byteArray = System.IO.File.ReadAllBytes(@"C:\myDoc.txt");
        System.IO.MemoryStream stream = new System.IO.MemoryStream(byteArray);

        //Callin the service at "Service()"
        FilesResource.InsertMediaUpload request = Service().Files.Insert(body, stream, "text/plain");
        request.Upload();
        File file = request.ResponseBody;
    }

所以我在这里创建了一个文件，因为我使用ServiceAccount进行了身份验证，即上传文件的位置。

问题

我需要能够创建/复制此文件给特定用户我的域名。并使该文件的用户所有者。

感谢所有帮助。

我会选择Marcel Balk anwser。

这样我们就会使用假冒！

我们可以使用服务帐户进行身份验证，然后使用我们域中的任何电子邮件帐户并上传文件。上传的文件将显示在我的文件下的用户云端硬盘中（不与我共享！）文件也归模拟帐户所有。在一个小控制台应用程序中测试：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Security.Cryptography.X509Certificates;
using System.Text;
using Google.Apis.Auth.OAuth2;
using Google.Apis.Drive.v2;
using Google.Apis.Drive.v2.Data;
using Google.Apis.Services;

namespace UseWebServiceMethod
{
    class Program
    {
        // Goto https://admin.google.com/AdminHome?chromeless=1#OGX:ManageOauthClients
        // Login met admin account => ****@***.***
        // Add/edit Client Name (Use Client ID of service account here) => 2***8.apps.googleusercontent.com
        // One or More API Scopes => https://www.googleapis.com/auth/drive 

        public const string ImpersonatedAccountEmail = "****@***.***";
        public const string ServiceAccountEmail      = "2******8@developer.gserviceaccount.com";
        public const string Key                      = @"C:\Users\Wouter\Desktop\GoogleTester\GoogleTester\A****c.p12";
        public const string FileToUpload             = @"C:\Users\Wouter\Desktop\GoogleTester\GoogleTester\whakingly.txt";
        public const string ApplicationName          = "A***l";

        static void Main()
        {
            var certificate = new X509Certificate2(Key, "notasecret", X509KeyStorageFlags.Exportable);
            var initializer = new ServiceAccountCredential.Initializer(ServiceAccountEmail)
            {
                Scopes = new[] { DriveService.Scope.Drive },
                User = ImpersonatedAccountEmail
            };

            var credential = new ServiceAccountCredential(initializer.FromCertificate(certificate));
            var driveService = new DriveService(new BaseClientService.Initializer()
            {
                HttpClientInitializer = credential,
                ApplicationName = ApplicationName
            });

            // Show all files
            var list = driveService.Files.List().Execute();
            if (list.Items != null)
                foreach (var fileItem in list.Items)
                {
                    Console.WriteLine(fileItem.Title + " - " + fileItem.Description);
                }
            Console.WriteLine("Press Enter to continue.");
            Console.ReadLine();

            // Upload a new file
            File body = new File();
            body.Title = "whakingly.txt";
            body.Description = "A whakingly (that a new word I created just there) file thats uploaded with impersonation";
            body.MimeType = "text/plain";
            byte[] byteArray = System.IO.File.ReadAllBytes(FileToUpload);
            var stream = new System.IO.MemoryStream(byteArray);
            FilesResource.InsertMediaUpload request = driveService.Files.Insert(body, stream, "text/plain");
            request.Upload();
            File file = request.ResponseBody;
            Console.WriteLine("Press Enter to continue.");
            Console.ReadLine();

            // Show all files
            var list2 = driveService.Files.List().Execute();
            if (list2.Items != null)
                foreach (var fileItem in list2.Items)
                {
                    Console.WriteLine(fileItem.Title + " - " + fileItem.Description);
                }
            Console.WriteLine("Press Enter to continue.");
            Console.ReadLine();

        }
    }
}

您可以通过将用户添加到代码中来轻松完成此操作。查看我添加的用户。

private static DriveService Service()
{
    var certificate = new X509Certificate2(Constants.P12, "notasecret",X509KeyStorageFlags.Exportable);
    var credential = new ServiceAccountCredential(
       new ServiceAccountCredential.Initializer(Constants.ServiceAccountEmail)
       {
           Scopes = new[] {DriveService.Scope.Drive},
           User="someuser@somedomain.someextension" //Add this to your code!
       }.FromCertificate(certificate));

    // Create the service.
    var service = new DriveService(new BaseClientService.Initializer()
    {
        HttpClientInitializer = credential,
        ApplicationName = "MyApplicationName",
    });

    return service;
}

然后转到admin.google.com - ＆gt;安全 - ＆gt;高级设置 - ＆gt;管理oauth客户端访问

将客户端ID添加到客户端名称，并将范围（http://www.googleapis.com/auth/drive）添加到＆＃34;一个或多个API范围字段＆＃34;
