为什么global.asax Application_Error方法不能捕获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

以及如何解决这个问题。我想记录每个抛出的异常以进行维护。

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从不触发用于Web服务。不知道是否有理由设计，但是它不起作用。

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 post （和后续）关于这个几年前，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


• 编写自定义的SOAP扩展或HTTPModule

我唯一关心的是第一个，即使它似乎是很多工作。

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