过滤elmah中的异常文本 [英] Filter on exception text in elmah

问题描述

示例：

System.Web.HttpException：请求定时去。我不想过滤掉所有HttpException，而只是过滤出超时请求。

System.Web.HttpException：超出最大请求长度。

我不想做的是编写自己的代码。那么可以用buildin-web.config配置来实现吗？

谢谢！

解决方案

是的，你可以。只需使用正则表达式来询问消息。有关如何比较异常消息的详细信息，请参阅下面的示例。

 < errorFilter> 
< test> 
<！ -  http://groups.google.com/group/elmah/t/cbe82cee76cc6321  - > 
<和> 
< is-type binding ='Exception'
 type ='System.Web.HttpException，System.Web，Version = 2.0.0.0，Culture = neutral，PublicKeyToken = b03f5f7f11d50a3a'/> 
< regex binding ='Exception.Message'
 pattern ='invalid\s + viewstate'
 caseSensitive ='false'/> 
< regex binding ='Context.Request.UserAgent'
 pattern ='Trident / 4（\。[0-9]）*'
 caseSensitive ='false'/> 
< /和> 
< / test> 
< / errorFilter> 
  

Is there a way to filter exceptions in elma using the exception message?

Examples:
"System.Web.HttpException: Request timed out." I don't want to filter out all HttpException, but only the timed-out requests.
"System.Web.HttpException: Maximum request length exceeded."

What I don't want to do is write own code for that. So is it possible to do this with the buildin-web.config configuration?

Thank you!

解决方案

Yes you can. Just use a regular expression to interrogate the message. See the example below for details on how to compare the exception message.

<errorFilter>
  <test>
    <!-- http://groups.google.com/group/elmah/t/cbe82cee76cc6321 -->
    <and>
      <is-type binding='Exception'
               type='System.Web.HttpException, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' />
      <regex binding='Exception.Message'
             pattern='invalid\s+viewstate'
             caseSensitive='false' />
      <regex binding='Context.Request.UserAgent'
             pattern='Trident/4(\.[0-9])*'
             caseSensitive='false' />
    </and>
  </test>
</errorFilter>
