充分利用ASP​​.NET PageMethods异常详细信息在客户端 [英] Getting Exception Details from ASP.NET PageMethods on the Client SIde

问题描述

我有一个PageMethod的，而我给从我的JavaScript调用
说

I am having a pagemethod to which i give a call from my JavaScript say

Pagemethods.MyMethod(MyParameter, onsucess, onfailure);

在code后面，我有这样的事情：

In the Code behind, I have something like this:

[WebMethod]
public static void MyMethod(Param)
{
   try{
     //DoSomething..
   }
   catch(exception ex)
   {
      //Log the exception and rethrow
      throw new exception(ex.innerexception);
   }
}

现在我面临的问题是：

每当我得​​到一个异常，
我再扔从code中的例外后面

Whenever i do get an exception, i re throw the exception from code behind

但在onFailure处的方法，我只是得到一个通用的消息说，
服务器的方法的MyMethod失败，以下错误：

But in the onfailure method, i just get a generic message saying that "the server method MyMethod failed with following error: "

我似乎并没有得到异常的详细信息并且只有通用的异常，

I don't seem to get the exception details and only that generic exception,

我怎样才能JavaScript的异常的详细信息，以便根据它的用户界面来处理/ JavaScript端。

How can i get the exception details on JavaScript, in order to handle it according on the UI/JavaScript side.

我已经验证了，这不是在web.config中的自定义错误设置的问题。

I have verified, that it is not an issue with custom errors settings in web.config.

有人可以告诉我，以这里发生了什么？

Can some one enlighten to me as to what is happening here?

PS：我已经通过code和异常每踩线被记录被重新抛出用适当的异常详细信息后，即信息

PS: i have stepped through each and every line of code and the exception after being logged is rethrown with the proper exception details i.e. message.

推荐答案

至于我，只要你明白

<customErrors mode="off" />

在你的web.config，该消息将返回到客户端。你确定你有这样的设置？

in your web.config, the message will be returned to client. Are you sure you have this setting ?

要显示你需要有oassed功能的页面方法调用的第三个参数的名称错误关联的消息：这个功能可以简单：

To display the message associated with error you need to have oassed the name of the function as the third parameter of the page method call : this function could be as simple as:

function onfailure( result )
{
   alert( result.get_message() );
}

这就是我们所拥有的，它的工作原理确定

That's what we have and it works OK
