MVC路线行动为Javascript文件

问题描述

我想添加一个MVC的途径来从控制器的JavaScript。我加入了以下路线，这是行不通的：

  routes.MapRouteWithName（
           DataSourceJS，//路线名称
           脚本/实体/ {}控制器/datasource.js，//带参数的URL
           新{控制器=家，行动=DataSourceJS} //参数默认，
           ， 空值
           ）;
 

但是，如果我改变路线没有的.js，我定位到脚本/实体/ {}控制/数据源它的工作原理。但是，我需要有.js文件扩展名在那里，我该如何使这项工作？

解决方案

IIS intercepts the request because it contains a file extension and hijacks it thinking it is a static file and not passing it to your application.

To make it work you should tell IIS not to do that. Inside the <system.webServer> section you could add the following handler to indicate that requests with the specified pattern should be handled by the managed pipeline:

<system.webServer>
    <handlers>
        ...
        <add name="ScriptsHandler" path="Scripts/Entities/*/datasource.js" verb="GET" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>
</system.webServer>

Some people might also tell you to use:

<modules runAllManagedModulesForAllRequests="true" />

but I wouldn't recommend you doing that because this means that all requests to static resources will now be flowing through the managed pipeline which could have a negative performance overhead for your application. The handler syntax allows you to selectively enable this only for certain route patterns and HTTP verbs.
