    php微信支付之公众号支付功能

    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,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。

    将该文件放到你的授权目录下,并在微信里访问这个文件,即可看到演示效果。效果如下:

     

    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'; //微信支付申请对应的公众号的APPID
    $appKey = 'xxxxx'; //微信支付申请对应的公众号的APP Key
    $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
    
    //①、获取用户openid
    $wxPay = new WxpayService($mchid,$appid,$appKey,$apiKey);
    $openId = $wxPay->GetOpenid();  //获取openid
    if(!$openId) exit('获取openid失败');
    //②、统一下单
    $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
    $jsApiParameters = $wxPay->createJsBizPackage($openId,$payAmount,$outTradeNo,$orderName,$notifyUrl,$payTime);
    $jsApiParameters = json_encode($jsApiParameters);
    ?>
