js发送post请求（用于验证数据）： var httpRequest = new XMLHttpRequest();//第一步：创建需要的对象 httpRequest.open('POST', 'http://127.0.0.1:8080', true); //第二步：打开连接 httpRequest.setRequestHeader("Content-type","application/x-www-form-urlencoded");//设置请求头 注：post方式必须设置请求头（在建立连接后设置请求头） httpRequest.send('name=teswe&ee=ef');//发送请求 将情头体写在send中
