外部登录Google和Facebook无法与身份服务器4一起使用

如何解决外部登录Google和Facebook无法与身份服务器4一起使用

public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllersWithViews();
            services.ConfigureIdentityServer(Configuration);

            services.ConfigureExternalOidcProvider(); --> Here is the register code

            services.AddRazorPages();
        }

 public static void ConfigureExternalOidcProvider(this IServiceCollection services)
        {
            services.AddAuthentication().AddGoogle("Google",options =>
            {
                options.SignInScheme = IdentityServerConstants.ExternalCookieAuthenticationScheme;

                options.ClientId = "xxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com";
                options.ClientSecret = "xxxxxxxxxxxxxxxxxxxxxx";
            }).AddFacebook(options =>
            {
                options.SignInScheme = IdentityServerConstants.ExternalCookieAuthenticationScheme;
                options.AppId = "xxxxxxxxxxxxxxxxxxxxxxxx";
                options.AppSecret = "xxxxxxxxxxxxxxxx";
            });
        }

#Identity Server外部控制器

 public IActionResult Challenge(string scheme,string returnUrl)
        {
            if (string.IsNullOrEmpty(returnUrl)) returnUrl = "~/";

            // validate returnUrl - either it is a valid OIDC URL or back to a local page
            if (Url.IsLocalUrl(returnUrl) == false && _interaction.IsValidReturnUrl(returnUrl) == false)
            {
                // user might have clicked on a malicIoUs link - should be logged
                throw new Exception("invalid return URL");
            }
            
            // start challenge and roundtrip the return URL and scheme 
            var props = new AuthenticationProperties
            {
                RedirectUri = Url.Action(nameof(Callback)),Items =
                {
                    { "returnUrl",returnUrl },{ "scheme",scheme },}
            };
            return Challenge(props,scheme);   
        }

在屏幕上，我具有Facebook和Google按钮

在页面的初始加载中，我具有以下网址

https：// localhost：5001 / Account / Login？ReturnUrl =％2Fconnect％2Fauthorize％2Fcallback％3Fclient_id％3DLocal％26redirect_uri％3Dhttps％253A％252F％252Flocalhost％253A5001％252Fauth-callback％26response_type％3Dcode％26scope％ 3Dopenid％2520profile％2520email％26state％3Df4821bac074e4ea0aa23c1c21071d309％26code_challenge％3D6rh-RLATVdTIeiOQ5Rzj-9uC5AV6cw1gYTNTMPBfPVY％26code_challenge_method％3DS256％26res

点击Google或Facebook后，URL更改为https：// localhost：5001 / Account / Login？ReturnUrl =％2FExternal％2FCallback

但是它没有重定向到Google或Facebook
