在 web.config 处理程序映射中指定应用程序根目录

发布于 2024-10-21 15:24:10 字数 1204 浏览 2 评论 0原文

我有一个带有 HttpHandler 的应用程序，用于处理对 .js 文件的任何请求。我只希望此处理程序处理应用程序根目录中请求的 *.js 文件。

处理程序映射如下所示：

<add name="HandleJS" path="*.js" verb="*" type="MyApp.JsHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" />

目前，此处理程序处理所有请求的 *.js 文件。这是我想要的行为的示例。

该请求将由处理程序处理：
http://localhost/myapps/approot/script.js

而这个不会由处理程序处理：
http://localhost/myapps/approot/dontProcessMe/script.js

我真的希望避免在处理程序路径中包含完整的绝对路径，因此我首先尝试了其他一些操作。

add 元素的 path 属性看起来不允许使用 ~/ 应用程序根机制，因此设置 path="~/*.js" 不起作用。

我还尝试复制内置于 IIS 中的 StaticFile 处理程序并执行以下操作：

<add name="MyStaticFiles" path="*/*.js" verb="*" modules="StaticFileModule" />

或

<add name="MyStaticFiles" path="dontProcessMe/*.js" verb="*" modules="StaticFileModule" />

两者都只返回 HTTP 状态为 200 的空白响应。

帮助我 Obi Wan Kenobi，你是我唯一的希望。

I have an application with an HttpHandler that processes any requests for a .js file. I only want this handler to process *.js files that are requested in the root of the application.

The handler mapping looks like this:

<add name="HandleJS" path="*.js" verb="*" type="MyApp.JsHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" />

Currently, this handler processes ALL requested *.js files. Here is an example of the behavior I want.

This request would be processed by the handler:
http://localhost/myapps/approot/script.js

and this one would not be processed by the handler:
http://localhost/myapps/approot/dontProcessMe/script.js

I'd really like to avoid including the full absolute path in the handler path so I tried some other things first.

It doesn't look like the path property of the add element allows the use of the ~/ application root mechanism, so setting path="~/*.js" doesn't work.

I've also tried replicating the StaticFile handler that's built into IIS and doing something like this:

<add name="MyStaticFiles" path="*/*.js" verb="*" modules="StaticFileModule" />

<add name="MyStaticFiles" path="dontProcessMe/*.js" verb="*" modules="StaticFileModule" />

Both of which just return a blank response with an HTTP status of 200.

Help me Obi Wan Kenobi, you're my only hope.

如果不需要处理，可以检查处理程序本身中的 RequestURL 返回实际文件吗？

public void ProcessRequest(HttpContext context)
{
    var applicationPath = context.Request.ApplicationPath;
    var pathAndQuery = context.Request.Url.PathAndQuery;

    var appRelativePath = pathAndQuery.Replace(applicationPath, "");

    var basePath = VirtualPathUtility.GetDirectory(appRelativePath);

    if (basePath != "/")
    {
        // load and return actual file
    }
    else
    {
        // custom logic
    }
}

May be inspect the RequestURL in the handler itself return the actual file if there is no processing needed?

public void ProcessRequest(HttpContext context)
{
    var applicationPath = context.Request.ApplicationPath;
    var pathAndQuery = context.Request.Url.PathAndQuery;

    var appRelativePath = pathAndQuery.Replace(applicationPath, "");

    var basePath = VirtualPathUtility.GetDirectory(appRelativePath);

    if (basePath != "/")
    {
        // load and return actual file
    }
    else
    {
        // custom logic
    }
}
