鉴定为谷歌API和OAuth2 [英] Authenticating to Google API with OAuth2

问题描述

我想出来的样品code从执行局使用C＃/。NET和，像其他一些样品中我都试过了，的code，创建一个使用身份验证变量中的对象的一部分，说他们的语法是错误的。这里是code，我有：

I am trying out the sample code from Perform Google Apps Domain-wide Delegation of Authority using C# / .NET and, like in some other samples I have tried, the part of the code that creates an object that uses the auth variable says that they syntax is wrong. Here is the code I have:

using System;
using System.Security.Cryptography;
using System.Security.Cryptography.X509Certificates;
using DotNetOpenAuth.OAuth2;
using Google.Apis.Authentication.OAuth2;
using Google.Apis.Authentication.OAuth2.DotNetOpenAuth;
using Google.Apis.Drive.v2;
using Google.Apis.Util;

namespace GoogleAPIDemo
{
    class DriveServiceObject
    {
        private const string SERVICE_ACCOUNT_EMAIL = "<some-id>@developer.gserviceaccount.com";
        private const string SERVICE_ACCOUNT_PKCS12_FILE_PATH = @"\path\to\<public_key_fingerprint>-privatekey.p12";

        /// <summary>
        /// Build a Drive service object authorized with the service account
        /// that acts on behalf of the given user.
        /// </summary>
        /// @param userEmail The email of the user.
        /// <returns>Drive service object.</returns>
        static DriveService BuildService(String userEmail)
        {
            X509Certificate2 certificate = new X509Certificate2(SERVICE_ACCOUNT_PKCS12_FILE_PATH, "notasecret",
                X509KeyStorageFlags.Exportable);

            var provider = new AssertionFlowClient(GoogleAuthenticationServer.Description, certificate)
            {
                ServiceAccountId = SERVICE_ACCOUNT_EMAIL,
                Scope = DriveService.Scopes.Drive.GetStringValue(),
                ServiceAccountUser = userEmail,
            };
            var auth = new OAuth2Authenticator<AssertionFlowClient>(provider, AssertionFlowClient.GetState);

            return new DriveService(auth);
        }
    }
}

这是我看到的错误是

(local variable) OAuth2Athenticator<AssertionFlowClient> auth

Error:
   The best overloaded method match for 'Google.Apis.DriveService.DriveService(Googel.Apis.Services.BaseClientService.Initializer)' has some invalid arguments

这是我第一次写一个使用谷歌的API和任何帮助，得到这个工作将是极大的AP preciated！一个应用程序

This is my first time writing an app that uses Google's APIs and any help getting this working would be greatly appreciated!

推荐答案

这一件作品：

        var provider = new AssertionFlowClient(
            GoogleAuthenticationServer.Description,
            new X509Certificate2(privateKeyPath, keyPassword, X509KeyStorageFlags.Exportable))
        {
            ServiceAccountId = serviceAccountEmail,
            Scope = DriveService.Scopes.Drive.GetStringValue(),
            ServiceAccountUser = driveHolderAccountEmail
        };
        var auth = new OAuth2Authenticator<AssertionFlowClient>(provider, AssertionFlowClient.GetState);

        m_service = new DriveService(new BaseClientService.Initializer()
        {
            Authenticator = auth
        });
