1.前端uniapp、vue3
2.接口PHP8、ThinkPHP8、MySQL8.0
3.微信支付- PHP官方示例文档
4.示例代码的模型及业务自己进行调整不要一味的复制粘贴
流程说明
1.小程序调用接口--获取拉起支付所用参数生成订单
2.拉起微信支付
3.支付完成-更改订单状态
参数说明
1.appid - 小程序id
2.mchid -- 商户号ID
3.certificate_serial -- 证书序列号
4.api_v3_key -- 支付密钥v3
5.apiclient_key.pem -- 商户API私钥文件根据微信支付下载器下载即可
6.cert.pem -- 微信支付平台证书文件注意此文件必须是手动下载的具体下载方式下方有说明
其他说明
1.本示例采用微信支付sdk
2.实际情况根据业务进行调整
3.通知回调未能正确返回
4.其他没毛病。
项目示例
1.安装微信支付 wechatpay -- sdk
composer require wechatpay/wechatpay
2.下载微信支付平台证书文件
1下载微信支付平台证书下载器 2进行详情页微信支付平台证书下载器 3下载CertificateDownloader.php点击下方红框直接下载文件就行文件位置随便放只要能用php命令运行就行 4下载证书直接复制下面命令改参数即可。 -k 支付密钥上方参数4 -m 商户号上方参数2 -f 商户密钥上方参数5需要完整路径 -s 证书序列号上方参数3 -o 生成证书地址需要本地完整路径
php -f ./CertificateDownloader.php -- -k 4202c8***** -m 16***** -f /****/apiclient_key.pem -s 25***** -o /*****/cert/
3.封装支付类完整示例如下
