多种ELMAH过滤条件 [英] Multiple ELMAH Filter Conditions

问题描述

我想知道是否可以通过以下逻辑编写ELMAH来过滤错误日志记录:

I wanted to know if there is a way that I can write ELMAH to filter out error logging under the following logic:

如果错误是favicon.ico OR 上的404，则错误是/1.xml OR 上的404，则错误是/2.xml

If the error is a 404 on favicon.ico OR the error is 404 on /1.xml OR the error is 404 on /2.xml

我找到了在favicon.ico上执行此操作的方法，如下所示:

I have found the way to just do it on the favicon.ico as shown:

 <errorFilter>
  <test>
    <and>
      <equal binding="HttpStatusCode" value="404" type="Int32" />
      <regex binding="Context.Request.ServerVariables['URL']" pattern="/favicon\.ico(\z|\?)" />
    </and>
  </test>
</errorFilter>

但是由于某些原因，我不明白如何在OR条件下执行此操作.任何帮助将不胜感激.

But for some reason, I cannot understand how to do it for the OR conditions. Any help will be much appreciated.

推荐答案

以下方法可以解决问题，否则您可以入门:

The following should do the trick or otherwise get you started:

<errorFilter>
  <test>
    <and>
      <equal binding="HttpStatusCode" value="404" type="Int32" />
      <or>
        <regex binding="Context.Request.ServerVariables['URL']" 
               pattern="/favicon\.ico(\z|\?)" />
        <regex binding="Context.Request.ServerVariables['URL']" 
               pattern="/[1-2]\.xml(\z|\?)" />
      </or>
    </and>
  </test>
</errorFilter>

基本上，这将过滤HTTP状态代码为404 且分组在or元素下的正则表达式模式之一与请求URL匹配的错误.

Basically, this will filter errors where the HTTP status code is 404 and one of the regular expressions patterns grouped under the or element match the request URL.
