将 C# Owin 响应类型从代码更改为令牌

Question

我正在尝试使用 OWIN 进行外部登录 Google/Facebook。

面临的问题是 owin 挑战不断将响应类型从令牌更改为代码。

挑战生成以下 URL： https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=client_dim&redirect_uri=mywebsite.com&scope=scope&state=state

这是 returns 来自 google 的错误。如果我将 response_type 更改为 token (response_type=token) 它会起作用。

这是 OAuth 选项

 OAuthOptions = new OAuthAuthorizationServerOptions
        {

            TokenEndpointPath = new PathString("/Token"),
            Provider = new ApplicationOAuthProvider(PublicClientId),
            AuthorizeEndpointPath = new PathString("/api/Account/ExternalLogin"),
            AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),

            // In production mode set AllowInsecureHttp = false
            AllowInsecureHttp = true,


        };

Google 中间件设置：

 app.UseGoogleAuthentication(new GoogleOAuth2AuthenticationOptions()
        {
            ClientId = "clientid",
            ClientSecret = "client secret",  
        });

这是挑战：

   var properties = new AuthenticationProperties() {   AllowRefresh = true, RedirectUri="mywebsite.co.za"  };


        Request.GetOwinContext().Authentication.Challenge(properties,LoginProvider);

        HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.Unauthorized);
        response.RequestMessage = Request;
        return Task.FromResult(response);

OWIN 是通用 MVC API 项目的基本设置。

将response_type重写为token的解决方案如下：

 GoogleOAuth2AuthenticationOptions googleOAuth2AuthenticationOptions = new GoogleOAuth2AuthenticationOptions
        {
            ClientId = "clientid",
            ClientSecret = "secret",

            Provider = new GoogleOAuth2AuthenticationProvider
            {
                OnApplyRedirect = context =>
                {
                    string redirect = context.RedirectUri.Replace("response_type=code", "response_type=token");
                    context.Response.Redirect(redirect);
                },

            },
        };

        app.UseGoogleAuthentication(googleOAuth2AuthenticationOptions);

它仍然回避问题，如果 google OAuth 2.0 需要 response_type=token 为什么 Owin.google 提供者使用 response_type=code.

将 C# Owin 响应类型从代码更改为令牌

Change C# Owin response type from code to token

c#

oauth-2.0

google-oauth

owin
