ASP.Net中的AJAX Web服务-如何进行全局错误处理？ [英] AJAX WebService in ASP.Net - how to global error handling?

问题描述

我的* .aspx站点中大约有50多个AJAX WebMethod，它由JQuery调用（有时是原始的jquery，有时是在lib之上）。

I have around 50+ AJAX WebMethods in my *.aspx site, which is called by JQuery (sometimes raw jquery, sometimes over lib's).

几个例子：

 [WebMethod]
    public static string GetLog()
    {
        DAL.LogService log = new DAL.LogService();
        string items = log.GetLog();
        return items;
    }

    [WebMethod]
    public static void ClearBenchmarks()
    {
        DAL.LogService log = new DAL.LogService();
        log.ClearBenchmarks();
    }

    [WebMethod]
    public static void WriteLog(string message1, string message2, string user, string type)
    {
        DAL.LogService.WriteLog(message1, message2, user, type);
    }

实际上，在大多数情况下，它们仅重定向到我应用程序的dataLayer ，但实际上，ofc上有50多个单一方法...

In fact in the most time, they only redirect to the dataLayer of my application, but in fact, ofc, I have 50+ single methods...

现在，我想在我的应用程序中包含错误处理-如何在不尝试的情况下进行全局操作捕获每种方法？

Now I want to include error handling in my application - how to do that globaly without having try catch in every single method?

推荐答案

这是.Net中的一个已知问题-global.asax的Application_Error永远不会在网络上触发服务。

This is a known issue in .Net - Application_Error of global.asax never fires for a web service.

所以您可以尝试遵循以下想法。

so you could try following ideas.

1. 您可以在每种Web服务方法周围放置try-catch

1. you could place a try-catch around each web service method

使用外观设计模式并将try-catch包含在父
对象中

Use a facade design pattern and include the try-catch in parent objects

编写自定义SOAP扩展或HTTPModule

Write a custom SOAP extension or HTTPModule
