我想为AJAX请求设置Cookie值，但下面的代码不起作用。

I want to set a cookie value on an AJAX request but the code below doesn't work.

$.ajax({
    type: "GET",    
    url: "http://example.com",
    cache: false,
    setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",

    });

推荐答案

基本上，ajax请求以及同步请求会自动发送您的文档Cookie。所以，你需要设置你的cookie为文档，而不是请求。但是，您的请求是跨域的，事情变得更复杂。基于此答案，除了设置文档Cookie，您应允许其发送到跨域环境：

Basically, ajax request as well as synchronous request sends your document cookies automatically. So, you need to set your cookie to document, not to request. However, your request is cross-domain, and things became more complicated. Basing on this answer, additionally to set document cookie, you should allow its sending to cross-domain environment:

type: "GET",    
url: "http://example.com",
cache: false,
// NO setCookies option available, set cookie to document
//setCookies: "lkfh89asdhjahska7al446dfg5kgfbfgdhfdbfgcvbcbc dfskljvdfhpl",
crossDomain: true,
dataType: 'json',
xhrFields: {
    withCredentials: true
},
success: function (data) {
    alert(data);
});
