微信支付统一下单，用PHP怎么实现？（代码全）

一、Model层，Wxpay.php

二、Controller层，Test.php

<?phpnamespace 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

<?phpnamespace 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);    }}
