微信企业付款API接口使用
微信企业支付开发文档：https://pay.weixin.qq.com/wiki/doc/api/tools/mch_pay.php?chapter=14_2
企业付款业务是基于微信支付商户平台的资金管理能力，为了协助商户方便地实现企业向个人付款，针对部分有开发能力的商户，提供通过API完成企业付款的功能。
比如目前的保险行业向客户退保、给付、理赔。
企业付款将使用商户的可用余额，需确保可用余额充足。查看可用余额、充值、提现请登录商户平台“资金管理”进行操作。
下面是微信企业付款接口THINKPHP控制器,
C('WX_APPID'),C('WX_MCHID'),C('WX_KEYC') 这三项我已事先写在配置文件中了
