使用 IdentityModel 4.1.1 的刷新令牌请求访问令牌

Question

我正在使用 IdentityModel 4.1.1 for OAuth2.0 现在我在创建 TokenClient 实例期间卡住了，该实例用于使用刷新令牌请求新的访问令牌。

这是我正在做的代码，

TokenClientOptions clientOptions = new TokenClientOptions();
clientOptions.ClientId = _configDetails.Where(x => x.Key == "ClientId").Select(x => x.Value).FirstOrDefault().ToString();
clientOptions.ClientSecret = _configDetails.Where(x => x.Key == "ClientSecret").Select(x => x.Value).FirstOrDefault().ToString();

//Create token client object object
var tokenClient = new TokenClient("?",clientOptions); //Here I need help what I have to pass as first parameter?


TokenResponse refereshtokenCallResponse = await tokenClient.RequestRefreshTokenAsync(token.RefreshToken);

下面是IdentityModel4.1.1 pkg提供的TokenClient类，

public class TokenClient
{
    public TokenClient(HttpMessageInvoker client, TokenClientOptions options);
    public TokenClient(Func<HttpMessageInvoker> client, TokenClientOptions options);

    public Task<TokenResponse> RequestAuthorizationCodeTokenAsync(string code, string redirectUri, string codeVerifier = null, IDictionary<string, string> parameters = null, CancellationToken cancellationToken = default(CancellationToken));
    public Task<TokenResponse> RequestClientCredentialsTokenAsync(string scope = null, IDictionary<string, string> parameters = null, CancellationToken cancellationToken = default(CancellationToken));
    public Task<TokenResponse> RequestDeviceTokenAsync(string deviceCode, IDictionary<string, string> parameters = null, CancellationToken cancellationToken = default(CancellationToken));
    public Task<TokenResponse> RequestPasswordTokenAsync(string userName, string password = null, string scope = null, IDictionary<string, string> parameters = null, CancellationToken cancellationToken = default(CancellationToken));
    public Task<TokenResponse> RequestRefreshTokenAsync(string refreshToken, string scope = null, IDictionary<string, string> parameters = null, CancellationToken cancellationToken = default(CancellationToken));
    public Task<TokenResponse> RequestTokenAsync(string grantType, IDictionary<string, string> parameters = null, CancellationToken cancellationToken = default(CancellationToken));
}

正如上面的类表示需要传递 HttpMessageInvoker 作为第一个参数，但我对此完全茫然。我还提到了 IdentityModel文件，但没有得到任何线索

Answer 1

您必须将 HttpClient 作为参数传递，并带有已设置的 BaseUrl。

查看GitHub上的测试，看看它是如何构建的。

编辑：为了消除任何混淆，HttpClient将 HttpMessageInvoker 作为基类。
