关于jquery：当ASP.NET异常在服务器上引发错误时，从jqXHR获取错误文本消息

Get the error text message from a jqXHR when the error was raised on the server by an ASP.NET exception

我有一个服务器端操作，如下所示：

1
2
3
4
5
6
7
8
9
10

namespace MyProduct.Presentation.Controllers
{
public class FooController : Controller
{
public ActionResult Delete(long[] fooIds)
{
throw new Exception("Something went wrong.");
}
}
}

我从客户端向这个控制器发出一个ajax请求，如下所示：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21

如何将文本设置为服务器上引发的Exception对象的Message属性？

在这种情况下，客户端使用HTTP状态代码500接收HTML响应。因此，我在Fiddler中看到我的响应如下所示：

1
2
3
