创建将自定义令牌交换为.Net Auth Cookie的Owin Auth提供程序 [英] Creating Owin Auth Provider that Exchanges a Custom Token for a .Net Auth Cookie
本文介绍了创建将自定义令牌交换为.Net Auth Cookie的Owin Auth提供程序的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试在2个.Net应用程序之间创建类似SSO的解决方案 .net应用程序1具有自定义令牌生成器和终结点，用于验证返回用户信息的令牌.
I am trying to create an SSO like solution between 2 .Net applications .Net app 1 has a custom token generator and endpoints to validate tokens that returns user information.
.Net应用程序2受Owin保护，它是典型的独立应用程序，用户可以使用密码和用户名直接登录.
.Net application 2 is protected using Owin and was a typical standalone app and a user would directly login using a password and username.
我创建了(基于对编码博客的热情和 Github )的自定义Owin提供程序将在Authorization标头中或以用户将单击.Net App 1中的链接并将查询字符串中的令牌发送到GET的链接(该链接不安全，我们最终将使用OpenID来作为用户的链接)中的查询参数值得我们仅在演示时使用它).我能够让令牌验证它并创建一个身份并进行身份验证，但我无法让提供者创建一个.Net Auth Cookie，以便后续请求得到身份验证，而不会出现401错误.
I created (based on Passion for Coding Blog and Github) a custom Owin provider that would look for a token either in a Authorization header or as a query parameter from a link that a user would click a link from .Net App 1 and send to the .Net App 2 the token in the query string as at GET (I know this is not secure we are eventually going to use OpenID for what it’s worth we just need this for a demo). I am able to get the token validate it and create an Identity and authenticate I just cant get the provider to create a .Net Auth Cookie so that subsequent requests are authenticated and not given a 401 error.

我还尝试仅使用自定义提供程序作为所提供的标准
I have also tried to just use the custom providers for the standard provided
OAuthBearerAuthenticationProvider
这是我尝试过的插件/提供程序的代码，只要没有401错误，我就没有偏好:
Here is the code for the plugins/providers that I tried I don't have a preference as long as there are no 401 errors:
提供商
using Microsoft.Owin.Security.OAuth;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace SomeOAuth
{
public class SomeOAuthBearerAuthenticationProvider : IOAuthBearerAuthenticationProvider
{
readonly string _parameterName;
public SomeOAuthBearerAuthenticationProvider(string parameterName)
{
_parameterName = parameterName;
}
public Task ApplyChallenge(OAuthChallengeContext context)
{
return Task.FromResult<object>(null);
}
public Task RequestToken(OAuthRequestTokenContext context)
{
string token = context.Token;
if(string.IsNullOrEmpty(token) && !string.IsNullOrEmpty(_parameterName))
{
token = context.Request.Query.Get(_parameterName);
}
if (!string.IsNullOrEmpty(token))
{
context.Token = token;
}
return Task.FromResult<object>(null);
}
public Task ValidateIdentity(OAuthValidateIdentityContext context)
{
context.Validated();
return Task.FromResult<object>(null);
}
}
}
和AccessTokenProvider
And the AccessTokenProvider
using Microsoft.Owin.Security;
using Microsoft.Owin.Security.Infrastructure;
using Newtonsoft.Json.Linq;
using System;
//using Newtonsoft.Json.Linq;
using System.Net;
using System.Net.Http;

using System.Threading.Tasks;
namespace SomeOAuth
{
public sealed class SomeTokenProvider : AuthenticationTokenProvider
{
public override async Task ReceiveAsync(AuthenticationTokenReceiveContext context)
{
using (var client = new HttpClient())
{
try
{
var request = new HttpRequestMessage(HttpMethod.Post, "https://someserver/API/Auth/Authenticate");
var s = new StringContent("{\"oauthtoken\":\"" + context.Token + "\"}", Encoding.UTF8, "application/json");
// var ts = s.ToString();
request.Content = new StringContent("{\"oauthtoken\":\"" + context.Token + "\"}", Encoding.UTF8, "application/json");
System.Diagnostics.Debug.WriteLine("Request:");
System.Diagnostics.Debug.WriteLine(request.ToString());
if (request.Content != null)
{
System.Diagnostics.Debug.WriteLine(await request.Content.ReadAsStringAsync());
}
System.Diagnostics.Debug.WriteLine("");
var response = await client.SendAsync(request);
if (response.StatusCode != HttpStatusCode.OK)
{
return;
}
var payload = JObject.Parse(await response.Content.ReadAsStringAsync());
var userId = payload.Value<string>("username");
//need to get the useid of the user as well as the name and role
var identity = new ClaimsIdentity("Some");
identity.AddClaim(new Claim(ClaimTypes.NameIdentifier, "someuser", null, "Some"));
/*
identity.AddClaim(new Claim(ClaimTypes.GivenName, user.FirstName + " " + user.LastName));
identity.AddClaim(new Claim(ClaimTypes.Email, user.ContactInfo.Email));
identity.AddClaim(new Claim(ClaimTypes.Sid, user.Guid.ToString()));
*/
identity.AddClaim(new Claim("http://schemas.microsoft.com/accesscontrolservice/2010/07/claims/identityprovider", "Some"));
context.SetTicket(new AuthenticationTicket(identity, new AuthenticationProperties()));
}
catch (Exception e)
{
Console.WriteLine("asdf e = " + e.Message);
}
}
}
}
}
推荐答案
您正在以错误的顺序注册中间件. owin中间件模型通过auth中间件工作，然后在返回上一个中间件之前在owin字典中放置指令(AuthenticationResponseGrant).如果该先前的中间件是外部cookie中间件，它将发出一个cookie. 我的博客文章中有更多详细信息.因此，切换这两行:
You're registering the middleware in the wrong order. The owin middleware model works through the auth middleware placing an instruction (AuthenticationResponseGrant) in the owin dictionary before returning to the previous middleware. If that previous middleware is the external cookie middleware it will issue a cookie. There's more detail in my blog post. So switch those two lines:
// Use a cookie to temp store information about a user logging in with a third party login provider
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
app.UseSomeAuthentication(new SomeAuthenticationOptions("testuser", "9"));
还有另一个问题.身份的AuthenticationType必须匹配一个cookie中间件. UseExternalSignInCookie方法在内部调用app.SetDefaultSignInAsAuthenticationType，因此在创建新的ClaimsIdentity时，您不应使用Some作为身份验证类型，而应通过options类上的SignInAsAuthenticationType传达app.GetDefaultSignInAsAuthenticationType()的结果.对app.GetDefaultSignInAsAuthenticationType()的调用通常是在中间件构造函数中完成的.
There's also another issue. The AuthenticationType of the identity must mach the one of the cookie middleware. The UseExternalSignInCookie method internally calls app.SetDefaultSignInAsAuthenticationType so when you create the new ClaimsIdentity you shouldn't use Some as authentication type but rather convey the result of app.GetDefaultSignInAsAuthenticationType() through the SignInAsAuthenticationType on the options class. The call to app.GetDefaultSignInAsAuthenticationType() is typically done in the middleware constructor.
