1. fetch 发送cors请求

为了让浏览器发送包含凭据的请求（即使是跨域源），要将credentials: 'include'添加到传递给 fetch()方法的init对象。

fetch('https://example.com', {
  credentials: 'include'  
})

 

2. xhr发送cor请求

const invocation = new XMLHttpRequest();
const url = 'http://example.com/';
if (invocation) {

invocation.open('GET', url, true);

invocation.withCredentials = true;

invocation.onreadystatechange = function(){};

invocation.send();

}
