找到php.ini配置文件，查找enable_post_data_reading变量，修改为打开状态，注释掉句前分好
; Whether PHP will read the POST data. ; This option is enabled by default. ; Most likely, you won't want to disable this option globally. It causes $_POST ; and $_FILES to always be empty; the only way you will be able to read the ; POST data will be through the php://input stream wrapper. This can be useful ; to proxy requests or to process the POST data in a memory efficient fashion. ; http://php.com/enable-post-data-reading enable_post_data_reading = On //大约656行，修改此条
修改配置后，发现还是不行，继续查阅资料。
搜集资料之后，发现vue-axios向后端post的是非表单数据（Ajax不同），在获取非表单数据时需要用php://input
$raw = file_get_contents('php://input');//获取非表单数据
echo $raw;//输出结果PS：post时前端请求头要设置为
headers: {
"Content-type": "application/json; charset=utf-8"
