如何在IdentityServer4中实现模拟

var users = new List<TestUser>
{
    new TestUser
    {
        SubjectId = "1",
        Username = "alice",
        Password = "password"
    },
    new TestUser
    {
        SubjectId = "2",
        Username = "bob",
        Password = "password"
    }
};

services.AddIdentityServer()
    .AddTestUsers(users)
    .AddInMemoryClients(Config.Clients)
    .AddInMemoryIdentityResources(Config.IdentityResources)
    .AddInMemoryApiResources(Config.ApiResources)
    .AddDeveloperSigningCredential();

public static IEnumerable<Client> Clients =>
    new List<Client>
    {
        new Client
        {
            ClientId = "client",
            AllowedGrantTypes = GrantTypes.ClientCredentials,
            ClientSecrets =
            {
                new Secret("secret".Sha256())
            },
            AllowedScopes = { "api1" }
        }
    };

public static IEnumerable<ApiResource> ApiResources =>
    new List<ApiResource>
    {
        new ApiResource("api1", "My API")
    };

public static IEnumerable<IdentityResource> IdentityResources =>
    new List<IdentityResource>
    {
        new IdentityResources.OpenId(),
        new IdentityResources.Profile()
    };

app.UseAuthentication();
app.UseAuthorization();
