c# - Web api 客户端 IdSrv3 身份验证中的访问 token

Question

我正在使用 IdSrv3 进行身份验证。我需要在我的 web api owin 客户端中获取 access_token 以在另一个 web api 客户端中通过承载身份验证。 我的 Startup.cs 代码:

public class Startup
{
        public void Configuration(IAppBuilder app)
        {

            ServicePointManager.ServerCertificateValidationCallback += (sender, cert, chain, sslPolicyErrors) => true;

            JwtSecurityTokenHandler.InboundClaimTypeMap.Clear();

            var identityServerPath = ConfigurationManager.AppSettings["IdentityServerPath"];

            app.UseIdentityServerBearerTokenAuthentication(new IdentityServerBearerTokenAuthenticationOptions
            {
                Authority = $"{identityServerPath}/core",

                RequiredScopes = new[] { "openid"},
                AuthenticationMode = Microsoft.Owin.Security.AuthenticationMode.Active,

                // client credentials for the introspection endpoint
                ClientId = "someid"
            });
        }
}

我正在尝试通过这种方式获取访问 token :

var claims = (User as ClaimsPrincipal).Claims;
var AccessToken = claims.First(x => x.Type == "access_token").Value;

如何获取access_token？声明变量为空。

Answer 1

您可以将“PreserveAccessToken”属性设置为 true(默认为 false)。例如:

app.UseIdentityServerBearerTokenAuthentication(new IdentityServerBearerTokenAuthenticationOptions
{
    Authority = "https://localhost:44331",
    ClientId = "apiOne",    
    ClientSecret = "secret",
    RequiredScopes = new[] {"apiOne"},
    ValidationMode = ValidationMode.ValidationEndpoint,
    PreserveAccessToken = true
});

这会将访问 token 保留为声明。然后您可以像上面那样检索它。除了声明是“token”，而不是“access_token”。
