ASP.NET中MVC使用AJAX调用JsonResult方法并返回自定义错误信息(3)
复制代码 代码如下: span class="pun"[span class="typ"JsonExceptionFilterAttributespan class="pun"]span class="pln" span class="kwd"publicspan class="pln" span class="typ"JsonResultspan class="p
复制代码 代码如下:
<span class="pun">[<span class="typ">JsonExceptionFilterAttribute<span class="pun">]<span class="pln">
<span class="kwd">public<span class="pln"> <span class="typ">JsonResult<span class="pln"> <span class="typ">FuckJson<span class="pun">()<span class="pln">

捕获异常后，你也可以先记一下log、或是根据你自己的需要处理一下这个异常，然后再throw。
最后我们的AJAX请求代码也得做修改，增加一个error的处理：
