    }
}

二、Controller层,Test.php

<?php
namespace app\goods\controller;
use app\common\model\Wxpay;
class Test
{
    /*
    * 调用微信支付
    * 一、获取微信用户的openid; 
    * 二、调用微信支付接口
    * 三、生成H5中使用的签名内容
    */
    public function wx()
    {
        $wxpay = new Wxpay();
        $openid = $wxpay->openid();
        $pay = $wxpay->payForWeixin($openid,date('YmdHis').rand(1,5),'0.1');
        $paySign =strtoupper(MD5('appId='.$pay['appId'].'&nonceStr='.$pay['nonceStr'].'&package='.$pay['package'].'&signType=MD5&timeStamp='.$pay['timeStamp'].'&key=536*****9e8'));
         $h5 = array(
            'appId'     => $pay['appId'],
            'timeStamp' => $pay['timeStamp'],
            'nonceStr'  => $pay['nonceStr'],
            'package'   => $pay['package'],
            'signType'  => $pay['signType'],
            'paySign'   => $paySign
        );
        $this->assign('wxpay',$h5);
        return view();
    }
}

三、HTML中调用微信支付,wx.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>订单示例</title>
</head>
<body>

<script type="text/javascript">
    function onBridgeReady(){
        WeixinJSBridge.invoke(
            'getBrandWCPayRequest', {
                "appId":"{$wxpay['appId']}",
                "timeStamp":"{$wxpay['timeStamp']}",
                "nonceStr":"{$wxpay['nonceStr']}",
                "package":"{$wxpay['package']}",
                "signType":"MD5",
                "paySign":"{$wxpay['paySign']}"
            },
            function(res){
                if(res.err_msg == "get_brand_wcpay_request:ok" ){
                    // 使用以上方式判断前端返回,微信团队郑重提示:
                    //res.err_msg将在用户支付成功后返回ok,但并不保证它绝对可靠。
                }
            });
    }
    if (typeof WeixinJSBridge == "undefined"){
        if( document.addEventListener ){
            document.addEventListener('WeixinJSBridgeReady', onBridgeReady, false);
        }else if (document.attachEvent){
            document.attachEvent('WeixinJSBridgeReady', onBridgeReady);
            document.attachEvent('onWeixinJSBridgeReady', onBridgeReady);
        }
    }else{
        onBridgeReady();
    }
</script>
</body>
</html>

四、接收微信支付返回结果,支付时设置的notify_url值,确保此链接外网能访问。wxpaynofiy.php

<?php
namespace app\home\controller;
class Wxpaynofiy
{
     public function notify()
    {
        $xml = isset($GLOBALS["HTTP_RAW_POST_DATA"]) ? $GLOBALS['HTTP_RAW_POST_DATA'] : file_get_contents("php://input");
        $data = xmlToArray($xml);
        if($data['return_code'] == 'SUCCESS' && $data['result_code'] == 'SUCCESS'){
            if($this->checkSign($data)) {
                $transaction_id = $data['transaction_id'];      //微信支付订单号
                $out_trade_no   = $data['out_trade_no'];        //商家订单号
                $this->errorLog('微信支付返回结果,微信支付订单号:'.$transaction_id.',商家订单号:'.$out_trade_no,[]);

            } else {
                $this->errorLog('微信支付返回结果签名验证失败',$data);
            }
        } else {
            $this->errorLog('微信支付返回结果',$data);
        }
        echo '<xml><return_code><![CDATA[SUCCESS]]></return_code><return_msg><![CDATA[OK]]></return_msg></xml>';
    }

    /*
     * 验证签名
     * @params array $result : 微信支付成功返回的结果数组
     * return bool $ret : 成功true,失败false
     * */
    private function checkSign(array $data)
    {
        $str = '';
        ksort($data);
        foreach ($data as $k => $v) {
            if($k != 'sign') $str .= $k.'='.$v.'&';
        }
        $temp = $str . 'key=5363******49e8';     //key:商户支付密钥
        $sign = strtoupper(md5($temp));
        return $sign == $data['sign'] ? true : false;
    }

    private function errorLog($msg,$ret)
    {
        file_put_contents(ROOT_PATH . 'runtime/error/wxpaynofiy.log', "[" . date('Y-m-d H:i:s') . "] ".$msg."," .json_encode($ret).PHP_EOL, FILE_APPEND);
    }
}
