微信商户密钥key找不到的问题

phpcoder_echo 2016-12-27

展开全文

做微信支付的时候遇到了这个纠结的问题，新版本的微信支付已经不需要paysignkey了，结果开发的时候发现还是要填写商户密钥key，说是在微信审核成功后发回的邮件中，可是找来找去也没有在邮件中找到这个参数，网上查了好多文章，都说在邮件中，可我邮件中确实没有啊，问了客服，答非所问，干脆自己在找找，终于在网上找到了这篇文章，感谢大神，终于解决了我的问题，同时也要分享出来，3.3.6的微信支付文档说的确实很少....

一、有言在先

1、俺家公众号开通微信支付时间是9月22号，所以适用文档版本号是v3.3.6，当时一不小心从微信客服那里拿到一个v2.7的文档，扑腾了1天时间，从一个个水坑里爬出来又跌入尿坑，把人坑惨了，后面找到相关人士才拿到真相，不过现在公众平台也可以下载到了~希望大家伙绕开这个坑！

2、最重要一点：此文有软广告嫌疑，慎入！先帮朋友们把评论写在这里~~~

二、需要到这些地方去扒参数

1、登录微信公众号管理后台mp.weixin.qq.com，在左侧菜单栏找到开发者中心，点开如下图就能看到AppID和AppSecret：

2、在微信支付通过之后，财付通会发3封邮件到申请人邮箱中，俺家之前开通过财付通的账户用于主站支付接口，不过这次又新发了一个财付通账号，不过让人惊喜的是这次微信支付免了保证金，不知为啥？

点开weixinpay那封邮件就可以看到这些账号信息，把附件中pem格式的文件下载保存到web服务器上，请记下文件绝对路径，在下面代码中需要用到：

3、登录微信商户平台（mch.weixin.qq.com），去设置商户支付密钥Key:

4、登录微信公众号管理后台mp.weixin.qq.com，设置支付配置，支付测试，支付白名单

三、找到参数来配置该个类class WxPayConf

class WxPayConf

{

//=======【基本信息设置】=====================================

//微信公众号身份的唯一标识。审核通过后，在微信发送的邮件中查看

const APPID = "填上二、1中看到的AppID";

//受理商ID，身份标识

const MCHID = "填上二、2中看到的MCHID";

//商户支付密钥Key。审核通过后，在微信发送的邮件中查看(如果没有,可以登录微信商户平台去设置)

const KEY = "填上二、3中设置的密钥";

//JSAPI接口中获取openid，审核后在公众平台开启开发模式后可查看

const APPSECRET = "填上二、1中看到的AppSecret";

//=======【JSAPI路径设置】===================================

//获取access_token过程中的跳转uri，通过跳转将code传入jsapi支付页面

const JS_API_CALL_URL = "http://www./wxpay/js_api_call.PHP";

//=======【证书路径设置】=====================================

//证书路径,注意应该填写绝对路径

const SSLCERT_PATH = "填上二、2中下载的pem文件放在服务器上的路径";

const SSLKEY_PATH = "填上二、2中下载的pem文件放在服务器上的路径";

//=======【异步通知url设置】===================================

//异步通知url，商户根据实际开发过程设定

const NOTIFY_URL = http://www.x/wxpay/notify_url.php;

}

四、JSAPI支付

微信JS API只能在微信内置浏览器中使用，其他浏览器调用无效。

下面代码是微信官方提供的JS API支付demo

include_once("WxPayHelper/WxPayHelper.php");

将其中的微信支付参数修改成自己申请得到的，然后将网页上传到微信支付目录下，使用公众号给测试账号回复该网页地址。用户就可以实现一次JS API支付。

五、NATIVE支付

采用了官方提供的demo，native支付模式2完成
