在web api客户端访问令牌客户端IdSrv3身份验证

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客户端传递承载认证。 我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" 
      }); 
     } 
} 

我想通过这种方式来获得访问令牌：

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

如何获得ACCESS_TOKEN？声明变量是空的。

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 
}); 

这会将访问令牌保留为声明。然后，您可以像上面那样进行检索。除此之外，声明是“标记”，而不是“access_token”。
