# oauth2 + oidc 实现 client部分
#### 任务16：oauth2 + oidc 实现 client部分
实现 client 之前启动一下上一节的 server，启动之前需要清除一些代码
**注释 Program 的 MigrateDbContext**
```
public static void Main(string[] args)
{
BuildWebHost(args)
//.MigrateDbContext((context, services) => {
// new ApplicationDbContextSeed().SeedAsync(context, services)
// .Wait();
//})
.Run();
}
```
**RegisterViewModel**
```
[Required]
//[DataType(DataType.EmailAddress)]
//public string Email{get;set;}
public string UserName { get; set; }
```
启动程序，使用 Config 中的 TestUser 登录
登录成功，不过现在是在本地，接下来需要把它放到客户端里面
新建一个 Asp.Net Core MVC 网站 MvcClient
**在 startup 的 ConfigureServices 中添加 Authentication**
```
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.Configure(options =>
{
// This lambda determines whether user consent for non-essential cookies is needed for a given request.
options.CheckConsentNeeded = context => true;
options.MinimumSameSitePolicy = SameSiteMode.None;
});
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
services.AddAuthentication(options =>
{
options.DefaultScheme = "Cookies";
options.DefaultChallengeScheme = "oidc";
})
.AddCookie("Cookies")
.AddOpenIdConnect("oidc", options =>
{
options.SignInScheme = "Cookies";
options.Authority = "http://localhost:5000";
options.RequireHttpsMetadata = false;
options.ClientId = "client";
options.ClientSecret = "secret";
options.SaveTokens = true;
});
}
```
**在 startup 的 Configure 中的 UseMvc 前添加 Authentication**
```
app.UseAuthentication();
```
**在 Program 的 CreateWebHostBuilder 中配置 Urls**
```
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseUrls("http://localhost:5001")
.UseStartup();
```
客户端设置为5001来启动，然后服务端设置为5000
**mvcCookieAuthSample 的 Program**
```
public static IWebHost BuildWebHost(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseEnvironment("Development")
.UseUrls("http://localhost:5000")
.UseStartup()
.Build();
```
**修改服务端的 Config 配置跳转地址**
```
public static IEnumerable GetClients()
{
return new List
{
new Client()
{
ClientId = "client",
AllowedGrantTypes = GrantTypes.Implicit,// 隐式模式
ClientSecrets =
{
new Secret("secret".Sha256())
},
RedirectUris = { "http://localhost:5001/signin-oidc" },
PostLogoutRedirectUris = { "http://localhost:5001/signout-callback-oidc" },
//AllowedScopes = {"api"},
AllowedScopes =
{
IdentityServerConstants.StandardScopes.Profile,
IdentityServerConstants.StandardScopes.OpenId,
}
}
};
}
```
**客户端的 Controller 打上 Authorize 标签**
```
[Authorize]
public class HomeController : Controller
```
**修改客户端 launchSettings.json 中的 applicationUrl**
```
"applicationUrl": "http://localhost:5001",
"sslPort": 0
```
启动服务端，客户端，可以看到跳转到登录界面
登录之后会跳转到
**在客户端 About.cshtml 页面显示 identity 的 claims**
```
@{
ViewData["Title"] = "About";
}
@ViewData["Title"]
@ViewData["Message"]
@*
Use this area to provide additional information.
*@
@foreach (var claim in User.Claims)
{
@claim.Type
@claim.Value
}
```
启动程序，跳转之后，点击 About 进入 About 页面
主要返回了服务端 Config 中配置的信息
```
public static IEnumerable GetIdentityResources()
{
return new List
{
new IdentityResources.OpenId(),
new IdentityResources.Profile(),
new IdentityResources.Email(),
};
}
```
