版本:CI3.0
微信掃碼支付:模式二
下載官方demo:http://pay.weixin.qq.com/wiki/doc/api/native.php?chapter=11_1
我是個小菜鳥,第一次研究這個,感覺無從下手,走了很多彎路后,也算是完成了?,F分享下希望對大家有幫助。
首先下載官方demo,將文件當在libraries/ 并命名為 Wxpay。在ci配置文件config/ 下新建 wxpay_config.php 并完成配置。
wxpay_config.php
<?php defined('BASEPATH') OR exit('No direct script access allowed'); /** * TODO: 修改這里配置為您自己申請的商戶信息 * 微信公眾號信息配置 * * APPID:綁定支付的APPID(必須配置,開戶郵件中可查看) * * MCHID:商戶號(必須配置,開戶郵件中可查看) * * KEY:商戶支付密鑰,參考開戶郵件設置(必須配置,登錄商戶平臺自行設置) * 設置地址:http://pay.weixin.qq.com/index.php/account/api_cert * * APPSECRET:公眾帳號secert(僅JSAPI支付的時候需要配置, 登錄公眾平臺,進入開發者中心可設置), * 獲取地址:http://mp.weixin.qq.com/advanced/advanced?action=dev&t=advanced/dev&token=2005451881&lang=zh_CN * @var string */ $config['appid'] = ''; $config['mch_id'] = ''; $config['apikey'] = ''; $config['appsecret'] = ''; $config['sslcertPath'] = APPPATH.'libraries/Wxpay/cert/apiclient_cert.pem'; $config['sslkeyPath'] = APPPATH.'libraries/Wxpay/cert/apiclient_key.pem';在libraries/ 下新建 CI_Wechatpay.php 。
