报错信息如下：
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
php5.6的版本在php.ini中的 （ always_populate_raw_post_data = -1 ） 把注释取消了就可以了，还有重启一下服务才能运行
