当redirect_uri包含查询字符串参数时，DotNetOpenAuth拒绝访问令牌请求-Java 学习之路

我试图实现OAuth2 Authorization Code Grant Flow但是我遇到了一个问题，如果redirect_uri包含查询字符串参数且资源所有者必须进行身份验证，我的客户端会收到错误 .

客户端能够请求验证码，但是当它尝试交换访问令牌的代码时，授权服务器以HTTP状态“400 Bad Request”和以下响应正文进行响应 .

{"error":"invalid_grant"}

如果redirect_uri不包含查询字符串参数，或者如果客户端在请求授权代码之前将其删除，那么它将完美地运行 . 如果资源所有者已经使用授权服务器进行了身份验证，那么它也可以正常运行 .

我的客户端正在使用DotNetOpenAuth并使用Glimpse我可以看到redirect_uri在授权代码请求和访问令牌请求之间是一致的 .

Glimpse日志中的失败如下所示：

Prepared outgoing EndUserAuthorizationRequestC (2.0) message for http://localhost:61814/authorize:
    client_id: localhost36618
    redirect_uri: http://localhost:36618/login?redirectURL=%2FProfile
    state: <state token>
    scope: authentication
    response_type: code

Processing incoming EndUserAuthorizationSuccessAuthCodeResponse (2.0) message:
    code: <authorization code>
    state: <state token>
    redirectURL: /Profile

Prepared outgoing AccessTokenAuthorizationCodeRequestC (2.0) message for http://localhost:61814/token:
    code: <authorization code>
    redirect_uri: http://localhost:36618/login?redirectURL=%2FProfile
    grant_type: authorization_code

http://localhost:61814/token returned 400 BadRequest: Bad Request

WebException from http://localhost:61814/token: {"error":"invalid_grant"}

但是，如果我从redirect_uri中省略了查询字符串参数，它可以工作：

Prepared outgoing EndUserAuthorizationRequestC (2.0) message for http://localhost:61814/authorize:
    client_id: localhost36618
    redirect_uri: http://localhost:36618/Login
    state: <state token>
    scope: authentication
    response_type: code

Processing incoming EndUserAuthorizationSuccessAuthCodeResponse (2.0) message:
    code: <authorization code>
    state: <state token>

Prepared outgoing AccessTokenAuthorizationCodeRequestC (2.0) message for http://localhost:61814/token:
    code: <authorization code>
    redirect_uri: http://localhost:36618/Login
    grant_type: authorization_code

Processing incoming AccessTokenSuccessResponse (2.0) message:
    access_token: <access token>
    token_type: bearer
    expires_in: 3599
    refresh_token: <refresh token>

同样，如果我在使用客户端之前登录授权服务器，它的工作原理如下：

Prepared outgoing EndUserAuthorizationRequestC (2.0) message for http://localhost:61814/authorize:
    client_id: localhost36618
    redirect_uri: http://localhost:36618/login?redirectURL=%2FProfile
    state: <state token>
    scope: authentication
    response_type: code

Processing incoming EndUserAuthorizationSuccessAuthCodeResponse (2.0) message:
    code: <authorization code>
    state: <state token>
    redirectURL: /Profile

Prepared outgoing AccessTokenAuthorizationCodeRequestC (2.0) message for http://localhost:61814/token:
    code: <authorization code>
    redirect_uri: http://localhost:36618/login?redirectURL=%2FProfile
    grant_type: authorization_code

Processing incoming AccessTokenSuccessResponse (2.0) message:
    access_token: <access token>
    token_type: bearer
    expires_in: 3599
    refresh_token: <refresh token>

OWIN授权服务器的OAuthAuthorizationServerProvider在成功的访问令牌授权代码请求上执行以下方法：

Provider.OnMatchEndpoint
Provider.OnValidateClientAuthentication
AuthorizationCodeProvider.Receive
Provider.OnValidateTokenRequest
Provider.OnGrantAuthorizationCode
Provider.OnTokenEndpoint
AccessTokenProvider.OnCreate
RefreshTokenProvider.OnCreate
Provider.OnTokenEndpointResponse

但是，不成功的访问令牌授权代码请求仅触及以下方法：

Provider.OnMatchEndpoint
Provider.OnValidateClientAuthentication
AuthorizationCodeProvider.Receive

AuthorizationCodeProvider.OnReceive具有以下实现：

private void ReceiveAuthenticationCode(AuthenticationTokenReceiveContext context)
{
 try
 {
  string ticket = _repo.RemoveTicket(context.Token);
  if (!string.IsNullOrEmpty(ticket))
  {
   context.DeserializeTicket(ticket);
  }
 }
 catch (Exception ex)
 {
  var wrapper = new Exception("Receive Authentication Code Error", ex);
  Logger.Error(wrapper);
 }
}

在调试器中，我可以看到一个有效的Token，从_repo成功检索序列化的Ticket，以及在方法完成之前的上下文对象中的反序列化的Ticket . 没有异常被抛出 . 成功和失败的请求之间的流程看起来相同，所以我不清楚什么是失败的，诊断工具事件日志在请求处理期间没有显示任何异常，只是在ReceiveAuthenticationCode完成后退出的线程 .

看起来问题出在我的测试客户端上，因为我能够使用Brent Shaffer's OAuth2 Demo PHP live demo重现完全相同的问题 .

测试客户端基于DotNetOpenAuth：

private static class Client
{
    public const string Id = "username";
    public const string Secret = "password";
}
private static class Paths
{
    public const string AuthorizationServerBaseAddress = "http://localhost:61814";
    public const string ResourceServerBaseAddress = "http://localhost:61814";
    public const string AuthorizePath = "/authorize";
    public const string TokenPath = "/token";
    public const string ResourceServerApiMethodPath = "/getaccount";
 }

public ActionResult Login(string code = "", string redirectURL = "/profile")
{
    var authorizationServerUri = new Uri(Paths.AuthorizationServerBaseAddress);
    var authorizationServer = new AuthorizationServerDescription
    {
        AuthorizationEndpoint = new Uri(authorizationServerUri, Paths.AuthorizePath),
        TokenEndpoint = new Uri(authorizationServerUri, Paths.TokenPath)
    };
    var client = new WebServerClient(authorizationServer, Client.Id, Client.Secret);


    if (!string.IsNullOrEmpty(code))
    {
        var apiResponse = null;
        var authorizationState = client.ProcessUserAuthorization();

        if (!string.IsNullOrEmpty(authorizationState?.AccessToken))
            apiResponse = GetApiResponse(authorizationState, Paths.ResourceServerApiMethodPath);

        if (apiResponse != null)
        {
            var identity = new ClaimsIdentity(new[] { new Claim("test", apiResponse),
                                                      new Claim(ClaimTypes.Role, "ResourceOwner")
                                                }, "ApplicationCookie");

            AuthMgr.SignIn(new AuthenticationProperties { IsPersistent = true }, identity);

            return Redirect(redirectURL);
        }
    }
    else
    {
        client.RequestUserAuthorization();
    }

    return View();
}

知道DotNetOpenAuth我可能做错了什么吗？为什么我在服务器端看不到无效请求？
