我们的web服务器由Apache换成了ngix运行出现如下图错误
Deprecated: Automatically populating $HTTP_RAW_POST_DATA is deprecated and will be removed in a future version. To avoid this warning set 'always_populate_raw_post_data' to '-1' in php.ini and use the php://input stream instead. in Unknown on line 0
Warning: Cannot modify header information - headers already sent in Unknown on line 0
解决办法：php.ini文件下：开启always_populate_raw_post_data = -1 之后保存重启即可
原因：开启后就可以用 $HTTP_RAW_POST_DATA 接收data，不过通常我们使用 php://input
