记一次自己亲自走通微信支付流程的过程：
首先拿到需要的公众号Appid、AppSecret、商户id、支付秘钥
然后到微信支付的开发文档中下载 需要的SDK版本，第一次是全部使用SDK只是放到服务器上走了一遍。
然后自己动手写了一遍
前端页面：
<?php
header("Content-type:text/html;charset=utf-8");
include ‘./lib/WxPay.Api.php‘;
include ‘./wxConfig.php‘;
include ‘./wxJsapiPay.php‘;
$jsapi = new wxJsapiPay();
$preOrder = $jsapi->makeWxPrepareOrder();
var_dump($preOrder);
?>
