Asp.net的HttpModule目录级别的Web.config [英] Asp.net HttpModule in directory level web.config

问题描述

我创建了一个自定义的HTTP模块，并希望将此模块添加到web配置。 Web应用程序是一个包含若干子应用的项目。一个子应用程序仅仅是一个文件夹，该文件夹中它有自己的web.config。我这样做，以便每个应用程序都有其自己的应用程序相关的内容，样式的configs等。

I created a custom http module and want to add this module to the web config. The web application is a project that contains several "sub applications". A sub application is just a folder, and within that folder it has its own web.config. I'm doing this so each application has its own application related contents, stylesheets, configs etc.

现在我创建了一个自定义HTTP模块。当添加这根Web.config，该模块正常工作。当添加HTTP模块配置到目录级的web.config（例如/Applications/MyApplication/web.config）时，模块不再被初始化。即使MSDN指出的HttpModules config元素也在努力在目录级别。任何人都知道如何解决此问题？

Now I created a custom http module. When adding this to the root web.config, the module is working properly. When adding the http module config to the directory-level web.config (e.g. /Applications/MyApplication/web.config) the module is not initialized anymore. Even though the msdn states that the HttpModules config element is also working at directory level. Anyone knows how to solve this?

推荐答案

要呼应<一href="http://stackoverflow.com/questions/2378586/asp-net-httpmodule-in-directory-level-web-config#comment3300541_2462947">Marvin斯密特的评论，似乎在配置＆LT;模块＆gt; 下＆LT;地点＆gt; 在的web.config 简单地不起作用 - 在这种方式中指定的任何模块都不会调用

To echo Marvin Smit's comment, it seems that configuring <modules> under a <location> in web.config simply does not work - any modules specified in this fashion are NOT invoked.

您的能有什么的做的是指定模块的根目录，并经控制的 appSetting ，可分层指定，按要求覆盖：

What you can do is to specify the module at root level, and have it controlled by an appSetting, which can be hierarchically specified and overridden as required:

<configuration>


  <appSettings>
    <add key="UseCustomModule" value="false"/>
  </appSettings>


  <location path="MyFolder">
    <appSettings>
      <add key="UseCustomModule" value="true"/>
    </appSettings>
    <system.webServer>
      <modules>
        <!-- CANNOT add module at this level, hence the overridden appSetting -->
      </modules>
    </system.webServer>
  </location>

  <system.webServer>
    <modules>
      <add name="CustomnModule" type="MyApplication.CustomModule" />
    </modules>
  </system.webServer>

</configuration>

然后中的$ C $下 CustomModule ：

    private static bool ModuleEnabled()
    {
        bool appSetting;
        if (!bool.TryParse(ConfigurationManager.AppSettings["UseCustomModule"], 
                           out appSetting))
            appSetting = false;

        return appSetting;
    }

ASP.NET会看到它，对 UseCustomModule 我们的当前位置的适当的值是一个我们看。

ASP.NET will see to it that the appropriate value of UseCustomModule for our current location is the one we read.
