推荐答案

接受的答案不会由于上述原因的工作。我张贴的链接到所描述的黑客避开了302的问题被透明地由浏览器来处理一个问题的注释：

The accepted answer does not work for the reasons given. I posted a comment with a link to a question that described a hack to get round the problem of the 302 being transparently handled by the browser:

不过，这是一个有点脏的黑客攻击，并经过多次周围挖我找到了我认为这是一个更好的解决方案 - 利用 JSON 。在这种情况下，你可以使所有响应Ajax请求有code 200，并在回复的正文中，添加某种JSON对象，你的Ajax响应处理程序，然后在适当的方式使用。

However, it is a bit of a dirty hack and after much digging around I found what I think is a better solution - use JSON. In this case, you can make all responses to ajax requests have the code 200 and, in the body of the response, you add some sort of JSON object which your ajax response handler can then use in the appropriate manner.
