asp.net-mvc - 无法找到 IdentityServer4 的 DiscoveryClient

Question

尝试访问发现客户端以访问其他端点并跟随，
http://docs.identityserver.io/en/aspnetcore1/endpoints/discovery.html

在 .Net 7.5 MVC 应用程序中安装了 IdentityModel nuget 包。但是找不到DiscoveryClient .

var discoveryClient = new DiscoveryClient("https://demo.identityserver.io");
var doc = await discoveryClient.GetAsync();

Identitymodel有什么变化吗？为 IdentityServer4
此外，无法找到“Tokenclient”的参数。

Answer 1

是的，你是对的。 IdentityModel NuGet 包中有很多更改。

下面的代码将帮助您:

HttpClient httpClient = new HttpClient();

//Below code will give you discovery document response previously we were creating using DiscoveryClient()

// They have created `.GetDiscoveryDocumentAsync()` extension method to get discovery document.

DiscoveryDocumentResponse discoveryDocument = await httpClient.GetDiscoveryDocumentAsync();


// To create a token you can use one of the following methods, which totally depends upon which grant type you are using for token generation.

Task<TokenResponse> RequestAuthorizationCodeTokenAsync(AuthorizationCodeTokenRequest)
Task<TokenResponse> RequestClientCredentialsTokenAsync(ClientCredentialsTokenRequest)
Task<TokenResponse> RequestDeviceTokenAsync(DeviceTokenRequest)
Task<TokenResponse> RequestPasswordTokenAsync(PasswordTokenRequest)
Task<TokenResponse> RequestRefreshTokenAsync(RefreshTokenRequest)
Task<TokenResponse> RequestTokenAsync(TokenRequest)

例如，如果要为密码授予类型创建 token ，请使用以下代码:

PasswordTokenRequest passwordTokenRequest = new PasswordTokenRequest()
            {
                Address = discoveryDocument.TokenEndpoint,
                ClientId = ClientName,
                ClientSecret = ClientSecret,
                GrantType = GrantTypes.ResourceOwnerPassword,
                Scope = scope,
                UserName = userName,
                Password = password
            };

httpClient.RequestPasswordTokenAsync(passwordTokenRequest);

我希望这能帮到您!
