js通过ajax发送header信息php接收

一、js：

<script>
if(window.XMLHttpRequest){  // code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}else{  // code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange = function(){
console.log(xmlhttp.readyState)
if(xmlhttp.readyState < 4){
console.log('loading...')
}else if (xmlhttp.readyState == 4 && xmlhttp.status == 200){
xmlDoc=xmlhttp.responseText;
console.log(xmlDoc)
}else{
console.log('fail...')
xmlhttp.abort()
}
}
xmlhttp.open("POST",'test.php',true,'user','pwd');
xmlhttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
xmlhttp.setRequestHeader('name', 'lee');
xmlhttp.send(null);
</script>

二、php：

<?php
header('Access-Control-Allow-Origin:*');
header('Access-Control-Allow-Credentials: true');
header('Access-Control-Allow-Methods:GET,PUT,POST,DELETE,OPTIONS');
header('Access-Control-Allow-Headers:WWW-Authenticate,Authorization,Set-Cookie,X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5, Content-Type, Date, X-Api-Version,name');
