这篇文章主要介绍了php版微信公众号接口实现发红包的方法,结合实例形式分析了php版微信公众号实现发红包的接口调用方法与相关使用注意事项,需要的朋友可以参考下

本文实例讲述了php版微信公众号接口实现发红包的方法。分享给大家供大家参考,具体如下:

最近接到一个任务,需要用微信来给用户自动发红包。要完成这个任务需要这么已经一些物料

先看一下效果图

只需要完成后面几步就可以了。

在微信公众号服务器上面调用红包代码

/*
**微信红包功能
*/
public function sendredpack(){
 $re_openid = $this->_pg('re_openid');
  $inputObj = new sendredpack_pub();
if(!$re_openid){
  return "微信红包功能,收红包用户不能为空";
}
  $inputObj->setParameter('re_openid',$re_openid); //收红包的用户的openid
  $inputObj->setParameter('send_name',"汽配一号铺"); //红包发送者名称
  $inputObj->setParameter('total_amount',"100"); //收红包的用户的金额,精确到分
  $inputObj->setParameter('total_num',"1"); //收红包的个数
  $inputObj->setParameter('wishing',"恭喜发财,谢谢支持,小小心意"); //收红包的用户的openid
  $inputObj->setParameter('client_ip',"121.40.157.243"); //调用接口的IP
  $inputObj->setParameter('act_name',"小邓感恩红包"); //红包主题
  $inputObj->setParameter('remark',"谢谢大家一路一来的支持"); //备注
  $response = $inputObj->getResult();
  return $response;
}
Copy after login

在微信支付辅助工具层加一个类,来完成红包功能

/**
* 微信发红包接口
**/
class sendredpack_pub extends Wxpay_client_pub
{
   function __construct() {
  //设置接口链接
   $this->url = "https://api.mch.weixin.qq.com/mmpaymkttransfers/sendredpack";
  //设置curl超时时间
  $this->curl_timeout = WxPayConf_pub::CURL_TIMEOUT;
}
/**
* 生成接口参数xml
*/
function createXml()
{
  try
 {
  $this->parameters["mch_billno"] = WxPayConf_pub::MCHID.createUnique();//商户订单号
  $this->parameters["wxappid"] = WxPayConf_pub::APPID;//公众账号ID
  $this->parameters["mch_id"] = WxPayConf_pub::MCHID;//商户号
  $this->parameters["nonce_str"] = $this->createNoncestr();//随机字符串
  $this->parameters["sign"] = $this->getSign($this->parameters);//签名
  return $this->arrayToXml($this->parameters);
 }catch (SDKRuntimeException $e) {
   die($e->errorMessage());
 }
}
/**
* 作用:获取结果,使用证书通信
*/
function getResult()
{
  $this->postXmlSSL();
  $this->result = $this->xmlToArray($this->response);
  return $this->result;
}
}
Copy after login

然后部署返微信支付的服务上面,就可以了!!然后在做微信公众号(这个公众号)的服务上面加入“红包”。就能达到上面的效果了

请您仔细阅读接口文档,参照文档进行开发,请注意,为了保证商户资金安全,接口强校验商户号与appid之间的绑定关系,以及appid与openid之间的对应关系(如果商户号与appid之间没有绑定关系,即appid没有申请微信支付或者申请微信支付商户号不匹配,或者openid归属appid错误,接口会返回报错)。
