[英]URL Rewrite Module (IIS) not working with OWIN Middleware hosted on IIS
如何将URL重写模块与OWIN中间件一起使用?
阅读http://www.asp.net/aspnet/overview/owin-and-katana/owin-middleware-in-the-iis-integrated-pipeline后 ,我说我应该能够在IIS管道中使用OWIN中间件,使用NuGet软件包:
Microsoft.Owin.Host.SystemWeb
这是我尝试使用的代码:
Web.config:
<system.webServer> <rewrite> <rules> <rule name="pandainserter" patternSyntax="ECMAScript" stopProcessing="true"> <match url=".*test.*" /> <conditions trackAllCaptures="true"> <add input="{REQUEST_URI}" pattern="/(.*?)/(.*)" /> </conditions> <action type="Rewrite" url="http://{HTTP_HOST}:20000/v1/{C:2}" appendQueryString="false" /> </rule> </rules> </rewrite> </system.webServer>
Startup.cs(OWIN):
[assembly: OwinStartup(typeof(ApiUrlRewriter.Startup))]
namespace ApiUrlRewriter
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
app.Run(context =>
{
string t = DateTime.Now.Millisecond.ToString();
return context.Response.WriteAsync(t + " Production OWIN App");
});
}
}
}
我想要做的是使用OWIN中间件,以允许CORS并修复OPTIONS飞行前的HTTP调用(此处描述: 如何在WebAPI 2中进行CORS身份验证? ),同时仍然具有使用IIS Rewrite模块进行重写的能力。我对同一服务器上其他站点的呼叫。
对于所有通话,我都会收到此错误。 将OWIN与IIS Rewrite模块一起使用时:
HTTP错误404.4-找不到您要查找的资源没有与之关联的处理程序。
详细错误信息:
IIS Web核心模块
通知MapRequestHandler
处理程序ExtensionlessUrl-Integrated-4.0
错误代码0x8007007b
似乎重写模块未注册,我不确定自己做错了什么,还是什至使用正确的方法?
首先,默认情况下, IIS URL Rewrite模块似乎在IIS Express上不起作用(我没有尝试在本地开发计算机上安装它)。
因此,在装有IIS和IIS URL重写模块的Windows Server 2012上运行此程序时,我可以看到我的HTTP请求开始被重写。
为了进一步参考,我发布了用于解决CORS Preflight问题的代码,同时还具有将HTTP请求重写到其他服务器的可能性。 请注意,这将允许来自任何来源的CORS请求。
