如何在 Visual Studio 2012 中为 ASP.NET MVC 4 配置 Microsoft.Owin.Security.Google？

Question

尝试在我的 ASP.NET MVC 4 项目中使用 Microsoft.Owin.Security.Google 使用 Google 配置设置和配置登录 Visual Studio 2012.

我一直在关注这篇文章： http://www.asp.net/mvc/overview/security/create-an-aspnet-mvc-5-app-with-facebook-and-google-oauth2-and-openid-sign-on 并检查了其他人，他们都提到将代码放在 Startup.cs 文件中，ASP.NET MVC 4 模板没有。

Microsoft Owin 库是否仅适用于 ASP.NET MVC 5？

是的，使用 ASP.NET MVC5 可以更容易地完成此任务：

在app_start/Startup.Auth.cs

using Microsoft.Owin.Security.Cookies;
using Microsoft.Owin.Security.Google;
using Microsoft.Owin.Security.Facebook;
using Owin;
using System.Web.Helpers;
using System.Security.Claims;
using System.Threading.Tasks;
using Microsoft.Owin.Security;

namespace ui.web
{
    public partial class Startup
    {
        public void ConfigureAuth(IAppBuilder app)
        {

            /* Local logins */
            app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
                LoginPath = new PathString("/login")
            });

            app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);

            /* Google */
            var googleOptions = new GoogleOAuth2AuthenticationOptions
            {
                ClientId = "clientid",
                ClientSecret = "secret",
            };
            googleOptions.Scope.Add("https://www.googleapis.com/auth/userinfo.profile");
            googleOptions.Scope.Add("https://www.googleapis.com/auth/userinfo.email");
            app.UseGoogleAuthentication(googleOptions);

            /* Facebook */
            var facebookOptions = new FacebookAuthenticationOptions
            {
                AppId = "clientid",
                AppSecret = "secret",
                BackchannelHttpHandler = new FacebookBackChannelHandler(),
                UserInformationEndpoint = "https://graph.facebook.com/v2.4/me?fields=id,name,email,first_name,last_name,location",
            };

            facebookOptions.Scope.Add("email");
            app.UseFacebookAuthentication(facebookOptions);

            AntiForgeryConfig.UniqueClaimTypeIdentifier = ClaimTypes.NameIdentifier;
        }
 }
}

FacebookBackChannelHandler

using System;
using System.Net.Http;

namespace ui.web.infrastructure.auth
{
    public class FacebookBackChannelHandler : HttpClientHandler
    {
        protected override async System.Threading.Tasks.Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, System.Threading.CancellationToken cancellationToken)
        {
            // Replace the RequestUri so it's not malformed
            if (!request.RequestUri.AbsolutePath.Contains("/oauth"))
            {
                request.RequestUri = new Uri(request.RequestUri.AbsoluteUri.Replace("?access_token", "&access_token"));
            }

            return await base.SendAsync(request, cancellationToken);
        }
    }
}
