PHP CURL POST

PHP CURL POST

最近公司运营平台因为要接通另外一个服务端的接口，要求模拟HTTP POST 提交数据。很久没有写过CURL了，特意上官网查了下文档以及复习下HTTP POST参数所代表的含义，根据HTTP POST参数所要求模拟的一个POST请求，发放出来给大家共同交流学习。代码的注释是

/*
 * [Content-Length] => 48
 * [Content-Type] => application/x-www-form-urlencoded
 * [Accept] => *\/*
 * [User-Agent] => Opera/9.80 (Windows NT 6.2; Win64; x64) Presto/2.12.388 Version/12.15
 * [Host] => localhost )
 */
