ajax设置自定义请求头信息

客户端请求

$.ajax({
type:"post",
url:urlstr,
dataType:'json',
async:true,
headers:{token:'abck'},
success:function (data) {
console.log(data.info);
console.log(JSON.stringify(data));
},
error:function (xhr,text) {
alert(text);
}
});

服务端代码

public function test_jsonp()
{
header("Access-Control-Allow-Headers: token");
$arr = getallheaders();
foreach($arr as $key=>$val){
$data[$key] = $val;
}
// echo $callback .'(' . json_encode($data) . ')';
echo json_encode($data);
exit;
/*
* 或者可以这样合并写 exit($callback .'(' . json_encode(array('info'=>'jsonp test success')) . ')');
* */
}
