PHP微信支付开发实例
PHP微信支付开发实例
这篇文章主要为大家详细介绍了PHP微信支付开发过程,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
PHP微信支付开发过程,分享给大家,供大家参考,具体内容如下
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**,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

- const CURL_PROXY_HOST = "0.0.0.0";//"10.152.18.220";
- const CURL_PROXY_PORT = 0;//8080;

- /**

- * 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
