通过CORS通过Ajax请求在浏览器上设置Cookie

通过CORS通过Ajax请求在浏览器上设置Cookie

ajax

尝试实施ajax登录/注册过程（不带身份验证的刷新站点）。使用Cookie来保存状态。我以为我现在就拥有此功能，但是由于某种原因，浏览器在从服务器取回cookie后仍未设置cookie。有人可以帮忙吗？这是请求和响应头：

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

请求标题

Accept:application/json, text/plain, */*
Accept-Charset:ISO-8859-1,utf-8;q=0.7,*;q=0.3
Accept-Encoding:gzip,deflate,sdch
Accept-Language:en-US,en;q=0.8
Connection:keep-alive
Content-Length:57
Content-Type:application/json;charset=UTF-8
Host:api.site.dev
Origin:http://site.dev
Referer:http://site.dev/
User-Agent:Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.101 Safari/537.11
withCredentials:true
X-Requested-With:XMLHttpRequest
Request Payload
{"email":"calvinfroedge@gmail.com","password":"foobar"}

响应标题

Access-Control-Allow-Credentials:true
Access-Control-Allow-Headers:X-Requested-With, Content-Type, withCredentials

X-Powered-By:PHP/5.4.7

我还在服务器返回的Chrome网络工具中看到了cookie：

必须通过将“ withCredentials”设置设置为true来发出AJAX请求（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;

如果您需要有关CORS，API安全性和cookie的详细说明，则该答案不适合StackOverflow注释。看看我写的这篇文章：http : //www.redotheweb.com/2015/11/09/api-
