Jquery 访问控制不允许原点允许原点

我一直在犯这个错误

1资源解释为脚本，但使用MIME类型application/json传输

我试图使用jquery查询在一个单独的域上获取json表单和php文件，这是我的php代码

json.php

<?php
header('Content-type: application/json');
$arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);
echo json_encode($arr);
?>

我相信你的问题的答案涉及到使用JSONP，因为它涉及跨域脚本

无论我是否指定

callback=

，返回的javascript中都没有回调：
