Google Drive SDK为用户创建文件

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;
    }

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;
    }

这样我们将使用模拟!

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。上传的文件将在我的文件下的用户驱动器中可见(不是与我共享!)文件也属于假冒的帐户。在一个小的控制台应用程序中测试:

您可以通过将用户添加到代码中轻松地做到这一点。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;
}

然后进入admin.google.com ->安全->高级设置->管理oauth客户端访问

将客户端id添加到客户端名称，并将您的范围(http://www.googleapis.com/auth/drive)添加到"一个或多个API范围字段"
