ASP.NET MVC故意阿贾克斯失败 [英] ASP.NET MVC Intentional Ajax Failure

问题描述

我想提出一个Ajax调用到我的控制器，将要进行长时间的操作。该操作可能会失败的原因有很多或成功。如果我想迫使我的AJAX调用失败code执行（错误），我需要什么，然后返回在我的控制器呢？只是抛出一个异常？

I am making an ajax call to my controller which is going to perform a long operation. The operation can fail for many reasons or succeed. If I want to force the failure code of my ajax call to execute ("error"), what do I need to do in my controller before returning? Just throw an exception?

推荐答案

抛出异常会导致状态code = 500，将调用错误处理程序，所以它应该是足够了。

Throwing an exception will lead to status code = 500 which will invoke the error handler, so it should be enough.
