jQuery，ajax请求标头中是否没有X-Requested-With = XMLHttpRequest? [英] Jquery, No X-Requested-With=XMLHttpRequest in ajax request header?

问题描述

某些时间，有时没有X-Requested-With标头.

SOME TIMES there is no X-Requested-With header, sometimes there is.

我检查了萤火虫，发现了，不知道为什么.

I checked in firebug and found that, don't know why.

因此，当我在Django中使用request.is_ajax时，有时会失败.

So when I use request.is_ajax in django, it fails sometimes.

有人知道如何解决吗?

好的，现在又发生了. 我打开页面，然后离开晚餐很长一段时间，当我回来时，它又发生了.我在萤火虫中记录了请求标头:

OK, now it happened again. I opened the page and then left for supper for a long while, when I came back, it happened again. I recorded request header in firbugs:

推荐答案

在1.6.2版中，我也遇到了这个问题，尤其是当页面已闲置一会儿时.扩展抖动的答案，这是在一个地方为每个请求冗余地添加了X-Requested-With.我把它放在我的母版页上.希望能解决这个问题.

I was facing this issue as well with version 1.6.2, especially when the page has been setting idle for a while. Expanding on jitter's answer, this is adding the X-Requested-With redundantly for every request in one place. I put this in my Master page. Hope this works out.

$(document).ajaxSend(function (event, request, settings) {
    request.setRequestHeader("X-Requested-With", "XMLHttpRequest");
});
