为什么 global.asax Application_Error 方法没有捕获 ASMX 服务抛出的异常? [英] Why global.asax Application_Error method does not catch exceptions thrown by ASMX service?

问题描述

以及如何修复它.为了维护目的，我想记录每个抛出的异常.

And how to fix it. I'd like to log every thrown exception for maintenance purpose.

推荐答案

这是 .Net 中的一个已知问题 - Application_Error 从不为 Web 服务触发.不确定是否有任何原因是设计使然，但它就是行不通.

This is a known issue in .Net - Application_Error never fires for a web service. Not sure if there's any reason it would be by design, but it just doesn't work.

Jeff Atwood 有一个帖子(和follow-up) 几年前关于这个，有以下想法:

Jeff Atwood had a post (and follow-up) about this a few years ago, with the following ideas:

• 在每个 Web 服务方法周围放置一个 try-catch 块
• 使用外观设计模式并将 try-catch 包含在父对象中
• 编写自定义 SOAP 扩展或 HTTPModule

我唯一关心的是第一个，尽管它看起来工作量很大.

The only one I care for is the first one, even though it seems like a lot of work.
