asp.net-mvc-4 – GoogleOauth2问题获取Internal Server 500错误

我决定尝试添加新的Google Oauth2中间件，它几乎破坏了一切。这是我的提供者配置从startup.auth.cs ..打开时，所有的提供程序，包括谷歌提供商获得一个500内部服务器在挑战。然而，内部服务器错误的细节是不可用的，我不知道如何打开任何调试或跟踪的Katana中间件。似乎像我们一样急于把谷歌的Oauth中间件送到门外。

        var googleOptions = new GoogleOAuth2AuthenticationOptions
        {
            ClientId = "228",ClientSecret = "k",CallbackPath = new PathString("/users/epsignin")
            SignInAsAuthenticationType = DefaultAuthenticationTypes.ExternalCookie,Provider = new GoogleOAuth2AuthenticationProvider
            {
                OnAuthenticated = context =>
                {
                    foreach (var x in context.User)
                    {
                        string claimType = string.Format("urn:google:{0}",x.Key);
                        string claimValue = x.Value.ToString();
                        if (!context.Identity.HasClaim(claimType,claimValue))
                            context.Identity.AddClaim(new Claim(claimType,claimValue,XmlSchemaString,"Google"));
                    }
                    return Task.FromResult(0);
                }
            }
        };
 
        app.UseGoogleAuthentication(googleOptions);

ActionMethod代码：

[AllowAnonymous]
    public ActionResult ExternalProviderSignIn(string provider,string returnUrl)
    {
       var ctx = Request.GetOwinContext();
        ctx.Authentication.Challenge(
            new AuthenticationProperties
            {
                RedirectUri = Url.Action("EPSignIn",new { provider })
            },provider);
        return new HttpUnauthorizedResult();
    }

解决方法

这花了我几个小时才弄清楚，但问题是由@CrazyCoder提到的CallbackPath。我意识到CallbackPath在public void ConfigureAuth(IAppBuilder app)中必须与在ChallengeResult中设置时不同。如果它们相同，则在OWIN中抛出500个错误。

我的代码是用于ConfigureAuth(IAppBuilder app)的

var googleOptions = new Microsoft.Owin.Security.Google.GoogleOAuth2AuthenticationOptions
{
    ClientId = "xxx",ClientSecret = "yyy",CallbackPath = new PathString("/callbacks/google"),//this is never called by MVC,but needs to be registered at your oAuth provider
 
    Provider = new GoogleOAuth2AuthenticationProvider
    {
        OnAuthenticated = (context) =>
        {
            context.Identity.AddClaim(new Claim("picture",context.User.GetValue("picture").ToString()));
            context.Identity.AddClaim(new Claim("profile",context.User.GetValue("profile").ToString()));
            return Task.FromResult(0);
        }      
    }
};
 
googleOptions.Scope.Add("email");
 
app.UseGoogleAuthentication(googleOptions);

我的’回调’控制器代码是：

// GET: /callbacks/googlereturn - callback Action
[AllowAnonymous]
public async Task<ActionResult> googlereturn()
{
        return View();
}
 
//POST: /Account/GooglePlus
public ActionResult GooglePlus()
{
    return new ChallengeResult("Google",Request.Url.GetLeftPart(UriPartial.Authority) + "/callbacks/googlereturn",null);  
    //Needs to be a path to an Action that will handle the oAuth Provider callback
}
 
private class ChallengeResult : HttpUnauthorizedResult
{
    public ChallengeResult(string provider,string redirectUri)
        : this(provider,redirectUri,null)
    {
    }
 
    public ChallengeResult(string provider,string redirectUri,string userId)
    {
        LoginProvider = provider;
        RedirectUri = redirectUri;
        UserId = userId;
    }
 
    public string LoginProvider { get; set; }
    public string RedirectUri { get; set; }
    public string UserId { get; set; }
 
    public override void ExecuteResult(ControllerContext context)
    {
        var properties = new AuthenticationProperties() { RedirectUri = RedirectUri };
        if (UserId != null)
        {
            properties.Dictionary[XsrfKey] = UserId;
        }
        context.HttpContext.GetOwinContext().Authentication.Challenge(properties,LoginProvider);
    }
}

>回调/谷歌似乎由OWIN处理
回调/ googlereturn似乎由MVC处理

它现在都在工作，虽然很想知道发生在帽子下的事情

除非另有要求，否则我的建议是让OWIN使用默认的重定向路径，并确保不要自己使用它们。
