## 客户端的设置

### 配置与IdentityServerSystem连接

//配置与IdentityServerSystem连接
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationScheme = "Cookies"
});
JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();

////For MVC Implicit Flow
app.UseOpenIdConnectAuthentication(new OpenIdConnectOptions
{
AuthenticationScheme = "oidc",
SignInScheme = "Cookies",
Authority = "http://localhost:5000",
ClientId = "testClientID",
RequireHttpsMetadata = false,
Scope = { "testclientidentity" },
GetClaimsFromUserInfoEndpoint = true,

SaveTokens = true
});

### 在Controller的Action中加入权限

using Microsoft.AspNetCore.Authorization;
public class TestsController : Controller
 [Authorize(Policy = "EditInfo")]
  public IActionResult Edit(){
  }
}

 

## IdentityServer4服务器端设置

### 创建ClientID

ClientID为testClientID，

### 创建IdentityScope

创建名为testclientidentity的IdentityScope

在其中加入一些UserClaim，比如"EditInfo"

## 测试

1. 利用用户名为"a"的用户登陆程序，在进入Tests/Edit时，会提示拒绝访问的错误界面

2. 给用户"a"加入名为"EditInfo"的UserClaim，再次进入Tests/Edit时，会正确显示界面
