通过CORS通过Ajax请求在浏览器上设置Cookie

尝试实现一个ajax登录/注册过程(不具有身份验证的刷新站点)。使用cookies来保存状态。我以为我现在有这个权利，但是由于某种原因，浏览器在从服务器恢复之后不设置cookie。任何人可以帮助？以下是请求和响应标头：

Request URL:http://api.site.dev/v1/login
Request Method:POST
Status Code:200 OK

请求标头

Accept:application/json,text/plain,*/*
Accept-Charset:ISO-8859-1,utf-8;q=0.7,*;q=0.3

我也从Chrome服务器返回的Chrome网络工具中看到cookie：

您的AJAX请求必须使用“withCredentials”设置设置为true(仅在XmlHttpRequest2和fetch中可用)：

var req = new XMLHttpRequest();
    req.open('GET','https://api.bobank.com/accounts',true); // force XMLHttpRequest2
    req.setRequestHeader('Content-Type','application/json; charset=utf-8');
    req.setRequestHeader('Accept','application/json');
    req.withCredentials = true; // pass along cookies
    req.onload = function()  {
        // store token and redirect
        let json;
        try {
            json = JSON.parse(req.responseText);
        } catch (error) {
            return reject(error);
        }
        resolve(json);
    };
    req.onerror = reject;

如果您想要对CORS，API安全性和Cookie的详细说明，答案不适用于StackOverflow注释。看看这篇文章我写的主题：http://www.redotheweb.com/2015/11/09/api-security.html
