PHP微信支付开发

Jun 23, 2016 pm 01:29 PM

1.开发环境
Thinkphp 3.2.3
微信:服务号,已认证
开发域名:http://test.paywechat.com (自定义的域名,外网不可访问)

2.需要相关文件和权限
微信支付需申请开通
微信公众平台开发者文档:http://mp.weixin.qq.com/wiki/home/index.html
微信支付开发者文档:https://pay.weixin.qq.com/wiki/doc/api/index.html
微信支付SDK下载地址:https://pay.weixin.qq.com/wiki/doc/api/jsapi.php?chapter=11_1

3.开发
下载好微信支付PHP版本的SDK,文件目录为下图:


把微信支付SDK的Cert和Lib目录放入Thinkphp,目录为

现在介绍微信支付授权目录问题,首先是微信支付开发配置里面的支付授权目录填写,

然后填写JS接口安全域。

最后设置网页授权

这些设置完,基本完成一半,注意设置的目录和我thinkphp里面的目录。

4.微信支付配置

把相关配置填写正确。

/** * 配置账号信息 */class WxPayConfig{    //=======【基本信息设置】=====================================    //    /** * TODO: 修改这里配置为您自己申请的商户信息 * 微信公众号信息配置 * * APPID:绑定支付的APPID(必须配置,开户邮件中可查看) * * MCHID:商户号(必须配置,开户邮件中可查看) * * KEY:商户支付密钥,参考开户邮件设置(必须配置,登录商户平台自行设置) * 设置地址:https://pay.weixin.qq.com/index.php/account/api_cert * * APPSECRET:公众帐号secert(仅JSAPI支付的时候需要配置, 登录公众平台,进入开发者中心可设置), * 获取地址:https://mp.weixin.qq.com/advanced/advanced?action=dev&t=advanced/dev&token=2005451881&lang=zh_CN * @var string */    const APPID = '';    const MCHID = '';    const KEY = '';    const APPSECRET = '';    //=======【证书路径设置】=====================================    /** * TODO:设置商户证书路径 * 证书路径,注意应该填写绝对路径(仅退款、撤销订单时需要,可登录商户平台下载, * API证书下载地址:https://pay.weixin.qq.com/index.php/account/api_cert,下载之前需要安装商户操作证书) * @var path */    const SSLCERT_PATH = '../cert/apiclient_cert.pem';    const SSLKEY_PATH = '../cert/apiclient_key.pem';    //=======【curl代理设置】===================================    /** * TODO:这里设置代理机器,只有需要代理的时候才设置,不需要代理,请设置为0.0.0.0和0 * 本例程通过curl使用HTTP POST方法,此处可修改代理服务器, * 默认CURL_PROXY_HOST=0.0.0.0和CURL_PROXY_PORT=0,此时不开启代理(如有需要才设置) * @var unknown_type */    const CURL_PROXY_HOST = "0.0.0.0";//"10.152.18.220";    const CURL_PROXY_PORT = 0;//8080;    //=======【上报信息配置】===================================    /** * TODO:接口调用上报等级,默认紧错误上报(注意:上报超时间为【1s】,上报无论成败【永不抛出异常】, * 不会影响接口调用流程),开启上报之后,方便微信监控请求调用的质量,建议至少 * 开启错误上报。 * 上报等级,0.关闭上报; 1.仅错误出错上报; 2.全量上报 * @var int */    const REPORT_LEVENL = 1;}

到这里基本上完成,可以在微信端打开http://test.paywechat.com/Charge/index.php/Test/index/
我的环境,HTTP服务器没有重写url,微信支付继续探索中,有些地方可能写的有问题或不足,望大家谅解,互相学习。
