php 微信红包发送方法【干货】

2017-05-20 14:38 204 查看

最新开发微信第三方平台小应用需要用到微信红包功能，下面共享下我的做法。

首先获取后台的配置信息

        $settings = $module['config'];

定义常量

define('ROOT_PATH', dirname(__FILE__));

define('DS', DIRECTORY_SEPARATOR);

define('SIGNTYPE', "sha1");

define('PARTNERKEY',$settings['password']);

define('APPID',$settings['appid']);

define('ADDONS_ROOT', IA_ROOT .'/addons/'.$name);

define('CERT_ROOT', ATTACHMENT_ROOT .'/'.$name.'/cert/'); // 证书的路径

生成订单号

        $mch_billno = $settings['mchid'].date('YmdHis').rand(1000, 9999);//订单号

导入并调用红包类

        include_once(IA_ROOT.'/addons/'.$name.'/pay/WxHongBaoHelper.php');

$commonUtil = new CommonUtil();

$wxHongBaoHelper = new WxHongBaoHelper();

$wxHongBaoHelper->setParameter("nonce_str", $commonUtil->create_noncestr());//随机字符串，不长于32位

$wxHongBaoHelper->setParameter("mch_billno", $mch_billno);//订单号

$wxHongBaoHelper->setParameter("mch_id", $settings['mchid']);//商户号

$wxHongBaoHelper->setParameter("wxappid", $settings['appid']);

//$wxHongBaoHelper->setParameter("nick_name", $settings['nick_name']);//提供方名称

//$wxHongBaoHelper->setParameter("send_name", $settings['send_name']);//红包发送者名称

$wxHongBaoHelper->setParameter("nick_name", $_W['account']['name']);//提供方名称

$wxHongBaoHelper->setParameter("send_name", $_W['account']['name']);//红包发送者名称

$wxHongBaoHelper->setParameter("re_openid", $openid);//相对于医脉互通的openid

$wxHongBaoHelper->setParameter("total_amount", $price * 100);//付款金额，单位分

$wxHongBaoHelper->setParameter("min_value", 1);//最小红包金额，单位分

$wxHongBaoHelper->setParameter("max_value", 200);//最大红包金额，单位分

$wxHongBaoHelper->setParameter("total_num", 1);//红包发放总人数

//$wxHongBaoHelper->setParameter("wishing", $settings['wishing']);//红包祝福诧

$wxHongBaoHelper->setParameter("wishing", "恭喜恭喜");//红包祝福诧

$wxHongBaoHelper->setParameter("client_ip", $settings['ip']);//调用接口的机器 Ip 地址

//$wxHongBaoHelper->setParameter("act_name", $settings['act_name']);//活劢名称

$wxHongBaoHelper->setParameter("act_name", "提现红包");//活劢名称

//$wxHongBaoHelper->setParameter("remark", $settings['remark']);//备注信息

$wxHongBaoHelper->setParameter("remark", "恭喜获得提现红包");//备注信息

$wxHongBaoHelper->setParameter("logo_imgurl", "https://www.baidu.com/img/bdlogo.png");//商户logo的url

$postXml = $wxHongBaoHelper->create_hongbao_xml();

$url = 'https://api.mch.weixin.qq.com/mmpaymkttransfers/sendredpack';

$responseXml = $wxHongBaoHelper->curl_post_ssl($url, $postXml);

$responseObj = simplexml_load_string($responseXml, 'SimpleXMLElement', LIBXML_NOCDATA);

$return_code=$responseObj->return_code;

$result_code=$responseObj->result_code;

判断返回结果

if($return_code=='SUCCESS'){

if($result_code=='SUCCESS'){

$result['type'] = "ok";

return $result;

}else{

if($responseObj->err_code=='NOTENOUGH'){

$result['content'] = "后台繁忙，请稍后再试！";

$result['type'] = 'error';

return $result;

}else if($responseObj->err_code=='TIME_LIMITED'){

$result['content'] = "现在非红包发放时间，请在北京时间0:00-8:00之外的时间前来领取";

$result['type'] = 'error';

return $result;

}else if($responseObj->err_code=='SYSTEMERROR'){

$result['content'] = "系统繁忙，请稍后再试！";

$result['type'] = 'error';

return $result;

}else if($responseObj->err_code=='DAY_OVER_LIMITED'){

$result['content'] = "今日红包已达上限，请明日再试！";

$result['type'] = 'error';

return $result;

}else if($responseObj->err_code=='SECOND_OVER_LIMITED'){

$result['content'] = "每分钟红包已达上限，请稍后再试！";

$result['type'] = 'error';

return $result;

}

$result['content'] = "红包发放失败！".$responseObj->return_msg."！请稍后再试！";

$result['type'] = 'error';

return $result;

}

}

if($return_code== 'FAIL'){

$result['content'] = $responseObj->return_msg;

$result['type'] = 'error';

return $result;

}

下面是WxHongBaoHelper.php定义

<?php

/**

* 微信红包类

*/

include_once("CommonUtil.php");

include_once("SDKRuntimeException.class.php");

include_once("MD5SignUtil.php");

class WxHongBaoHelper

{

var $parameters; //cft 参数

function __construct()

{

}

function setParameter($parameter, $parameterValue) {

$this->parameters[CommonUtil::trimString($parameter)] = CommonUtil::trimString($parameterValue);

}

function getParameter($parameter) {

return $this->parameters[$parameter];

}

protected function create_noncestr( $length = 16 ) {

$chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";

$str ="";

for ( $i = 0; $i < $length; $i++ ) {

$str.= substr($chars, mt_rand(0, strlen($chars)-1), 1);

//$str .= $chars[ mt_rand(0, strlen($chars) - 1) ];

}

return $str;

}

function check_sign_parameters(){

if($this->parameters["nonce_str"] == null ||

$this->parameters["mch_billno"] == null ||

$this->parameters["mch_id"] == null ||

$this->parameters["wxappid"] == null ||

$this->parameters["nick_name"] == null ||

$this->parameters["send_name"] == null ||

$this->parameters["re_openid"] == null ||

$this->parameters["total_amount"] == null ||

$this->parameters["max_value"] == null ||

$this->parameters["total_num"] == null ||

$this->parameters["wishing"] == null ||

$this->parameters["client_ip"] == null ||

$this->parameters["act_name"] == null ||

$this->parameters["remark"] == null ||

$this->parameters["min_value"] == null

)

{

return false;

}

return true;

}

/**

例如：

appid： wxd930ea5d5a258f4f

mch_id： 10000100

device_info： 1000

Body： test

nonce_str： ibuaiVcKdpRxkhJA

第一步：对参数按照 key=value 的格式，并按照参数名 ASCII 字典序排序如下：

stringA="appid=wxd930ea5d5a258f4f&body=test&device_info=1000&mch_i

d=10000100&nonce_str=ibuaiVcKdpRxkhJA";

第二步：拼接支付密钥：

stringSignTemp="stringA&key=192006250b4c09247ec02edce69f6a2d"

sign=MD5(stringSignTemp).toUpperCase()="9A0A8659F005D6984697E2CA0A

9CF3B7"

}

throw new SDKRuntimeException("生成签名参数缺失！" . "<br>");

}

$commonUtil = new CommonUtil();

ksort($this->parameters);

$unSignParaString = $commonUtil->formatQueryParaMap($this->parameters, false);
