IdentityServer4在.net6中使用的变化

IdentityServer4在.net6中不再使用DiscoveryClient

之前使用的DiscoveryClient连接Identity Server，这次使用时发现找不到了，查了文档发现已更新为使用HttpClient

发现服务。会连接identity server的/.well-known/openid-configuration构建

using IdentityModel.Client;

var client = new HttpClient();
var disco = await client.GetDiscoveryDocumentAsync("http://localhost:5000");
if (disco.IsError)
{
    Console.WriteLine(disco.Error);
    return;
}

Console.WriteLine("Hello, World!");

获取Token的多种方式

TokenClient也没有使用了，新的写法

RequestTokenAsync

var response = await client.RequestTokenAsync(new TokenRequest
{
    Address = "https://demo.identityserver.io/connect/token",
    GrantType = "custom",

    ClientId = "client",
    ClientSecret = "secret",

    Parameters =
    {
        { "custom_parameter", "custom value"},
        { "scope", "api" }
    }
});

RequestClientCredentialsTokenAsync

var response = client.RequestClientCredentialsTokenAsync(new ClientCredentialsTokenRequest
    {
        Address = disco.TokenEndpoint,

        ClientId = "client",
        ClientSecret = "secret",
        GrantType = "client_credentials",
        Scope = "api"
    }).Result;

RequestPasswordTokenAsync

var response = await client.RequestPasswordTokenAsync(new PasswordTokenRequest
{
    Address = "https://demo.identityserver.io/connect/token",

    ClientId = "client",
    ClientSecret = "secret",
    Scope = "api1",

    UserName = "bob",
    Password = "bob"
});

RequestAuthorizationCodeTokenAsync

var response = await client.RequestAuthorizationCodeTokenAsync(new AuthorizationCodeTokenRequest
{
    Address = IdentityServerPipeline.TokenEndpoint,

    ClientId = "client",
    ClientSecret = "secret",

    Code = code,
    RedirectUri = "https://app.com/callback",

    // optional PKCE parameter
    CodeVerifier = "xyz"
});

RequestDeviceTokenAsync

var response = await client.RequestDeviceTokenAsync(new DeviceTokenRequest
{
    Address = disco.TokenEndpoint,

    ClientId = "device",
    DeviceCode = authorizeResponse.DeviceCode
});

获取刷新Token

var response = await _client.RequestRefreshTokenAsync(new RefreshTokenRequest
{
    Address = TokenEndpoint,

    ClientId = "client",
    ClientSecret = "secret",

    RefreshToken = "xyz"
});
