1，linux，多商户分销 2,严格按照http://www.fecmall.com/doc/fecshop-guide/instructions/cn-1.0/guide-fecshop_payment_wx_method.html，文档做了几次检查 2，手机浏览器支付成功，但支付页未刷新，订单状态显示待支付 3，在微信公众号里支付，点击支付，显示异常页面，跟踪页面提交地址为：http://XXXXX.com/payment/wxpayjsapi/start/payment/wxpayjsapi/start
微信内部使用微信支付报错排查：
对代码进行输出
./vendor/fancyecommerce/fecshop/lib/wxpay/example/WxPay.JsApiPay.php
public function GetOpenid() { //通过code获得openid if (!isset($_GET['code'])){ //触发微信返回code码 $baseUrl = urlencode('http://'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'].$_SERVER['QUERY_STRING']); $url = $this->__CreateOauthUrlForCode($baseUrl); Header("Location: $url"); exit(); } else { //获取code码，以获取openid $code = $_GET['code']; $openid = $this->getOpenidFromMp($code); return $openid; } }
进行输出：
输出为：
结果原因，因为使用了反向代理，致使搞乱了传递的$_SERVER 参数，使 $_SERVER['REQUEST_URI'] 和 $_SERVER['QUERY_STRING']的值相同，进而导致的问题，需要排查nginx反向代理的问题。
$_SERVER
$_SERVER['REQUEST_URI']
$_SERVER['QUERY_STRING']
对于 $_SERVER['REQUEST_URI'] 和 $_SERVER['QUERY_STRING'] 参数：
1，http://localhost/aaa/ (打开aaa中的index.php) 结果： $_SERVER['QUERY_STRING'] = ""; $_SERVER['REQUEST_URI'] = "/aaa/"; $_SERVER['SCRIPT_NAME'] = "/aaa/index.php"; $_SERVER['PHP_SELF'] = "/aaa/index.php"; 2，http://localhost/aaa/?p=222 (附带查询) 结果： $_SERVER['QUERY_STRING'] = "p=222"; $_SERVER['REQUEST_URI'] = "/aaa/?p=222"; $_SERVER['SCRIPT_NAME'] = "/aaa/index.php"; $_SERVER['PHP_SELF'] = "/aaa/index.php"; 3，http://localhost/aaa/index.php?p=222&q=333 结果： $_SERVER['QUERY_STRING'] = "p=222&q=333"; $_SERVER['REQUEST_URI'] = "/aaa/index.php?p=222&q=333"; $_SERVER['SCRIPT_NAME'] = "/aaa/index.php"; $_SERVER['PHP_SELF'] = "/aaa/index.php";
