路径参数/ URL友好字符

使用服务堆栈3.9.21。在IIS 7.5中托管应用程序。使用集成的4.0.30319 ASP.NET应用程序池。

为了便于说明,假设我有以下路径(由DTO和相应的请求处理程序支持):

/cars/{id}

有些汽车的ID中包含了我认为必须进行URL编码的字符 - pipe,|,就是其中之一。当我发送请求以获取具有例如“1 | 2”的id的汽车时,我得到一个具有以下堆栈跟踪的好旧500:

[ArgumentException]: Illegal characters in path.
   at System.IO.Path.CheckInvalidPathChars(String path)
   at System.IO.Path.GetFileName(String path)
   at ServiceStack.MiniProfiler.UI.MiniProfilerHandler.MatchesRequest(IHttpRequest request) in C:\src\ServiceStack\src\ServiceStack\MiniProfiler\UI\MiniProfilerHandler.cs:line 24
   at ServiceStack.WebHost.Endpoints.ServiceStackHttpHandlerFactory.GetHandler(HttpContext context, String requestType, String url, String pathTranslated) in C:\src\ServiceStack\src\ServiceStack\WebHost.Endpoints\ServiceStackHttpHandlerFactory.cs:line 153
   at System.Web.HttpApplication.MaterializeHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

无论我是否对路径中的管道进行URL编码,我都会得到这个。我该如何解决这个问题?

DTO

using ServiceStack.ServiceHost;

namespace SSUEB
{
    [Route("/cars/{id}", "GET")]
    public class ById
    {
        public string Id { get; set; }
    }
}

端点

using System.Collections.Generic;
using System.Net;
using ServiceStack.Common.Web;
using Stack = ServiceStack.ServiceInterface;

namespace SSUEB
{
    public class Cars : Stack.Service
    {
        public object Get(ById byId)
        {
            return new HttpResult(new Dictionary<string, string> {{"id", byId.Id}}, HttpStatusCode.OK);
        }
    }
}

应用

using ServiceStack.WebHost.Endpoints;

namespace SSUEB
{
    public class SSUEB : AppHostBase
    {
        public SSUEB() : base("ServiceStack toy service", typeof(SSUEB).Assembly)
        {
        }

        public override void Configure(Funq.Container container)
        {
            ServiceStack.Text.JsConfig.EmitCamelCaseNames = true;
            SetConfig(new EndpointHostConfig { DebugMode = true });
        }
    }
}

这一个:

curl -v -X GET -H "Accept: application/json" http://localhost:80/dealership/cars/123%20456

获取预期的200响应:

{"id":"123 456"}

但是这个:

curl -v -X GET -H "Accept: application/json" http://localhost:80/dealership/cars/123%7C456

导致最初报告的问题。

IIS请求日志显示%7C被解码为管道并且%20被解码(在日志中至少作为加号)。后者导致200(OK)响应,前者 - 500(内部服务器错误)。

2012-12-03 22:21:20 127.0.0.1 GET /dealership/cars/123|456 - 80 - 127.0.0.1 curl/7.27.0 500 0 0 5
2012-12-03 22:21:25 127.0.0.1 GET /dealership/cars/123+456 - 80 - 127.0.0.1 curl/7.27.0 200 0 0 1

我已经看过这个,而且我们无法在ServiceStack中做任何事情,因为它是由ASP.NET生成的预先验证的异常,请参阅{{3}关于如何在IIS / ASP.NET中允许无效字符。

注意:由于它没有通过ASP.NET,因此可以使用ServiceStack的自托管主机,如Scott Hanselman's post所示。
