怎么用php跨域请求

header(“Access-Controller-Allow-Origin:*”);//用于解决同源策略，跨域访问
 jQuery里ajax请求携带cookie：
 $.ajax({
 url:"{:url(‘index/Hello/api’)}",
 type:“get”,
 xhrFields: {
 withCredentials: true // 携带跨域cookie
 },
 success:function(data,suc){
 console.log(data.data);
 }
 })
 header(“Access-Control-Allow-Credentials:true”);//用于接收跨域cookie
 $_COOKIE[“name”];全局变量获取；
 headers:{“token”:“liu”}axios里config配置请求头
 header(‘Access-Control-Allow-Headers:token’);//跨域响应设置请求头
