IdentityServer4 CookieAuthenticationScheme设置

在使用IdentityServer4时报错，错误如下：
           

ERROR|IdentityServer4.Startup|Authentication scheme Bearer is configured for IdentityServer,
 but it is not a scheme that supports signin (like cookies). Either configure the default 
 authentication scheme with cookies or set the CookieAuthenticationScheme on the 
 IdentityServerOptions.
           

解决办法：

1、在Startup.cs中的services.AddIdentityServer添加如下代码。

services.AddIdentityServer(options=>options.Authentication.CookieAuthenticationScheme="Cookie")
           

services.AddIdentityServer(options=>options.Authentication.CookieAuthenticationScheme="Cookie")
                .AddDeveloperSigningCredential()
                .AddInMemoryIdentityResources(Resources.GetIdentityResourceResources())
                .AddInMemoryApiResources(Resources.GetApiResources())
                .AddInMemoryClients(Clients.GetClients())
                .AddResourceOwnerValidator<ResourceOwnerPasswordValidator>();
           

2、在services.AddAuthentication中添加AddCookie(“Cookie”);

services.AddAuthentication(IdentityServerAuthenticationDefaults.AuthenticationScheme)
                .AddIdentityServerAuthentication(options =>
                {
                    options.Authority = $"http://{Configuration["Identity:IP"]}:{Configuration["Identity:Port"]}";
                    options.RequireHttpsMetadata = false;
                    options.ApiName = "WebApi";
                    options.ApiSecret = "DAWebApi";
                }).AddCookie("Cookie");
