PHP 微信支付-借助SDK

# 微信 2024-05-05 14:15 0 20 来源：云博客

记一次自己亲自走通微信支付流程的过程：

首先拿到需要的公众号Appid、AppSecret、商户id、支付秘钥
然后到微信支付的开发文档中下载需要的SDK版本，第一次是全部使用SDK只是放到服务器上走了一遍。
然后自己动手写了一遍

前端页面：

<?phpheader("Content-type:text/html;charset=utf-8");include ‘./lib/WxPay.Api.php‘;include ‘./wxConfig.php‘;include ‘./wxJsapiPay.php‘;$jsapi = new wxJsapiPay();$preOrder = $jsapi->makeWxPrepareOrder();var_dump($preOrder);?><!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1"/> <title>微信支付</title> <style type="text/css"> .pay-btn{ display: block; width: 200px; height: 32px; color:#FFF; text-align: center; background-color: #09BB07; border-radius: 0.2rem; line-height: 32px; margin:0 auto; margin-top: 10%; } </style></head><body> <span class="pay-btn" onclick="wxpay()">微信支付</span> <script type="text/javascript"> window.onload = function(){ if (typeof WeixinJSBridge == "undefined"){ if( document.addEventListener ){ document.addEventListener(‘WeixinJSBridgeReady‘, editAddress, false); }else if (document.attachEvent){ document.attachEvent(‘WeixinJSBridgeReady‘, editAddress); document.attachEvent(‘onWeixinJSBridgeReady‘, editAddress); } }else{ editAddress(); } }; function wxpay() { if (typeof WeixinJSBridge == "undefined"){ if( document.addEventListener ){ document.addEventListener(‘WeixinJSBridgeReady‘, jsApiCall, false); }else if (document.attachEvent){ document.attachEvent(‘WeixinJSBridgeReady‘, jsApiCall); document.attachEvent(‘onWeixinJSBridgeReady‘, jsApiCall); } }else{ jsApiCall(); } } //调用微信JS api 支付 function jsApiCall() { WeixinJSBridge.invoke( ‘getBrandWCPayRequest‘, { "appId":"<?php echo $preOrder[‘appId‘]; ?>", //公众号名称，由商户传入 "timeStamp":"<?php echo $preOrder[‘timeStamp‘]; ?>", //时间戳，自1970年以来的秒数 "nonceStr":"<?php echo $preOrder[‘nonceStr‘]; ?>", //随机串 "package":"<?php echo $preOrder[‘package‘]; ?>", "signType":"<?php echo $preOrder[‘signType‘]; ?>", //微信签名方式： "paySign":"<?php echo $preOrder[‘paySign‘]; ?>" //微信签名 }, function(res){ WeixinJSBridge.log(res.err_msg); alert(res.err_code+res.err_desc+res.err_msg);// alert(JSON.stringify(res)); //查看错误消息 } ); } </script></body></html>

php页面：

include_once ‘./lib/WxPay.Api.php‘;include_once ‘./wxConfig.php‘;class wxJsapiPay { /** * 创建微信支付预订单数据 */ public function makeWxPrepareOrder(){// $openid = $this->GetOpenid(); $wxOrderData = new WxPayUnifiedOrder(); $wxOrderData->SetOut_trade_no(‘20180806125346‘); //设置订单号 $wxOrderData->SetTrade_type(‘JSAPI‘); //微信支付方式 $wxOrderData->SetBody(‘我的微信支付‘); //商品描述 $wxOrderData->SetFee_type(‘CNY‘); //货币种类 CNY人民币 $wxOrderData->SetTotal_fee(1); //设置订单总价 $wxOrderData->SetOpenid(‘o75920o4fPcP74pTWI8MfDyYsB_A‘); //设置用户openid $wxOrderData->SetNotify_url(‘http://paysdk.weixin.qq.com/notify.php‘); //设置微信支付回掉地址 $wxPayConfig = new wxConfig(); $wxOrder = WxPayApi::unifiedOrder($wxPayConfig,$wxOrderData); $jsApiParameters = $this->GetJsApiParameters($wxOrder); $jsApiParameters = json_decode($jsApiParameters,TRUE); return $jsApiParameters; }}
