IdentityServer4获取访问令牌

Question

Is it possible to get generated access token from IExtensionGrantValidator or ICustomTokenRequestValidator implementations or I must implement another validator? I can't find any properties from which I can get access token.

Answer 1

Well, within the context of retrieving it initially from IdentityServer, the token is in the AccessToken property of the TokenResponse instance returned.

From within an ASP.NET Core application authenticating via IdentityServer, the fact that it came from IdentityServer is inconsequential. Generically, to retrieve an access token, you'd use:

using Microsoft.AspNetCore.Authentication;

...

var token = await HttpContext.GetTokenAsync("access_token");

Answer 2

Here is a workaround, deps: IdentityServer4.AccessToken Validation 2.7 + IdentityModel 3.10

    services.AddScoped(provider =>
                {
                    var httpService = provider.GetService<IHttpContextAccessor>();

                    var token = httpService.HttpContext.Request.Headers["Authorization"][0].Remove(0, "Bearer ".Length);
                    var userGuid = Guid.Parse(httpService.HttpContext.User.FindFirst("sub").Value);

                    // Use token 

                });
