我想在 AJAX 请求上设置 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 请求和同步请求都会自动发送您的文档 cookie.因此，您需要将 cookie 设置为文档，而不是请求.但是，您的请求是跨域的，事情变得更加复杂.基于这个答案，另外设置文档cookie，你应该允许它发送到跨域环境:

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);
});
