最簡單的IdentityServer實現——IdentityServer

1.新建項目

新建ASP .Net Core項目IdentityServer.EasyDemo.IdentityServer，選擇.net core 2.0

引用IdentityServer4

2.定義Api資源

添加一個Config.cs文件,在其中定義Api資源
Api資源指上述的Api，可以有多個，在這里設置了，並且Api的配置與之匹配，IdentityServer才能識別那個Api
eg.IdentityServer項目的Api資源池里面有一個名叫"api1"的Api資源，Api項目中設置ApiName為"api1"，則雙方匹配

public static IEnumerable<ApiResource> GetApiResources()
{
    return new List<ApiResource>
    {
        //參數是資源名稱,資源顯示名稱
        new ApiResource("api1", "My API")
    };
}

3.定義客戶端Client

繼續在Config.cs中添加Client
Client指的是各個調用服務的客戶端，可以有多個
用戶要設置ClientId，這是它的唯一標志，在Client列表里面，ClientId不能重復，ClientSecrets是用來驗證用戶的密碼，AllowedScopes記錄了它的權限范圍
注意：可以多個客戶端共用一個ClientId，則對於IdentityServer來說，這些客戶端都是一個"Client"。這個在你的客戶端都具有相同的權限范圍，或者說要求完全一樣的時候，可以簡化為這樣。

public static IEnumerable<Client> GetClients()
{
    return new List<Client>
    {
        new Client
        {
            ClientId = "client",

            AllowedGrantTypes = GrantTypes.ClientCredentials,

            // 用於驗證的secret
            ClientSecrets =
            {
                new Secret("secret".Sha256())
            },

            // 允許的范圍
            AllowedScopes = { "api1" }
        }
    };
}

4.配置IdentityServer

在services里面添加IdentityServer，並且將Api資源和Client集合放入內存，交給IdentityServer

public void ConfigureServices(IServiceCollection services)
{
    //配置IdentityServer,包括把Api資源,Client集合,密鑰保存在內存
    services.AddIdentityServer()
        //設置臨時簽名憑據
        .AddDeveloperSigningCredential()
        //從Config類里面讀取剛剛定義的Api資源
        .AddInMemoryApiResources(Config.GetApiResources())
        //從Config類里面讀取剛剛定義的Client集合
        .AddInMemoryClients(Config.GetClients());
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseIdentityServer();
}

5.在屬性中將IdentityServer項目的端口號設置為5000

6.查看IdentityServer的相關信息

通過這個網址查看:http://localhost:5000/.well-known/openid-configuration
