php实现微信原生支付(扫码支付)功能
发布:smiling 来源: PHP粉丝网 添加日期:2021-09-20 16:03:38 浏览: 评论:0
网上的很多PHP微信扫码支付接入教程都颇为复杂,且需要配置和引入较多的文件,本人通过整理后给出一个单文件版的,只有200行代码,希望可以给各位想接入微信扫码支付的带来些许帮助和借鉴意义。
直接运行该文件即可得到一个支付二维码的图片。
需要注意的事项:
1.该文件需放到支付授权目录下,可以在微信支付商户平台->产品中心->开发配置中设置。
2.如提示签名错误可以通过微信支付签名验证工具进行验证:微信公众平台支付接口调试工具
代码如下:
- <?php
- header('Content-type:text/html; Charset=utf-8');
- $mchid = 'xxxxx'; //微信支付商户号 PartnerID 通过微信支付商户资料审核后邮件发送
- $appid = 'xxxxx'; //公众号APPID 通过微信支付商户资料审核后邮件发送
- $apiKey = 'xxxxx'; //https://pay.weixin.qq.com 帐户设置-安全设置-API安全-API密钥-设置API密钥
- $wxPay = new WxpayService($mchid,$appid,$apiKey);
- $outTradeNo = uniqid(); //你自己的商品订单号
- $payAmount = 0.01; //付款金额,单位:元
- $orderName = '支付测试'; //订单标题
- $notifyUrl = 'https://www.xxx.com/wx/'; //付款成功后的回调地址(不要有问号)
- $payTime = time(); //付款时间
- $arr = $wxPay->createJsBizPackage($payAmount,$outTradeNo,$orderName,$notifyUrl,$payTime);
- //生成二维码
- $url = 'http://qr.liantu.com/api.php?text='.$arr['code_url'];
- echo "<img src='{$url}' style='width:300px;'>";
