微信H5支付开发全过程(除内置微信以外的浏览器)

前言:网上都是~ 呵呵 自己搞 只要花时间 多问客服总会有的

只说程序不说准备工作 自己ID 或者秘钥都准备好了  写的有点儿乱 可以把所有的方法 放在一个文件中调用

 public function wechat ($doorder,$doczmoney,$doczbody) {
        // H5 微信支付
        $wxUrl = "https://api.mch.weixin.qq.com/pay/unifiedorder"; //下单接口
        $appid = ""; //公众账号ID
        $mch_id ="";// 商户号
        $nonce_str =$this->randStrpay(); //随机字符串
        $key ="";
        $body = $doczbody; //商品描述
        $out_trade_no = $doorder;// 商户订单号
        $total_fee = $doczmoney*100;// 我数据库存的是元 转换下 标价金额 f分
        $device_info = ‘‘;        

        $spbill_create_ip = $this->getClientp();// 终端IP
        $notify_url ="";// 通知地址
        $trade_type ="MWEB";// 交易类型
        //组合数组 方便字典升序
        $paraMap = array(‘appid‘=>$appid,
            ‘mch_id‘=>$mch_id,
            ‘nonce_str‘=>$nonce_str,
            ‘body‘=>$body,
            ‘out_trade_no‘=>$out_trade_no,
            ‘total_fee‘=>$total_fee,
            ‘spbill_create_ip‘=>$spbill_create_ip,
            ‘notify_url‘=>$notify_url,
            ‘trade_type‘=>$trade_type,
            ‘device_info‘=>$device_info
        );
        // 字典升序 下边有方法 这是摘出来的 自己复制到自己的位置 然后调用 下边几个调用都一样
        $singStr = \Ruifi\Service\CommonService::formatParaMap($paraMap);

            //获取singvalue值
        $sign =$this->autostr($singStr,$key);
        // sign 值添加到数组
        $mapSing = array_merge($paraMap,array(‘sign‘=>$sign));
        //print_r($mapSing);die;
        //数组转xml
        $arrXml = \Ruifi\Service\CommonService::arrayToXml($mapSing);       
        //post 发送
        $wechatreslut = \Ruifi\Service\CommonService::postXmlCurl($arrXml,$wxUrl);
        //接受xml
        $xmlToarr = \Ruifi\Service\CommonService::xmlToArray($wechatreslut);
        $xmlToarrStr = \Ruifi\Service\CommonService::utf8_to_gbk_arr($xmlToarr);       
        if ($xmlToarrStr[‘result_code‘] ==‘SUCCESS‘){
            $wxMurl = $xmlToarrStr[‘mweb_url‘];
            header("Location: $wxMurl");
         
        }
    }
    //32位随机字符串
    function randStrpay($length=32) {
        $rand=‘‘;
        $randstr= ‘ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789‘;
        $max = strlen($randstr)-1;
        mt_srand((double)microtime()*1000000);
        for($i=0;$i<$length;$i++) {
            $rand.=$randstr[mt_rand(0,$max)];
        }
        return $rand;
    }
    // 签名算法
    function autostr($singStr,$key){
        $stringSignTemp = $singStr."&key=$key";
        $sign = md5($stringSignTemp);
        $signValue = strtoupper($sign);
        return $signValue;
}
//获取IP
    function getClientp(){
        $cip ="unknow";
        if($_SERVER[‘REMOTE_ADDR‘]){
            $cip = $_SERVER[‘REMOTE_ADDR‘];
        }elseif(getenv("REMOTE_ADDR")){
            $cip =getenv("REMOTE_ADDR");
        }
        return $cip;
    }

 

这些方法是 上边调用的 你自己随意
