这篇文章主要介绍了PHP中如何实现微信公众号自动发送红包API，具有一定借鉴价值，感兴趣的朋友可以参考下，希望大家阅读完这篇文章之后大有收获，下面让小编带着大家一起了解一下。

具体如下：

贴出核心接口代码至于数据自己填写，接口测试ＯＫ
wechat_packet.php

weixin_appid = C('wap_weixin_appid');  $this->mch_id = C('wechat_mch_id');  $this->send_name = C('wechat_send_name');  $this->wishing = C('wechat_wishing');  $this->act_name = C('wechat_act_name');  $this->client_ip = $_SERVER['SERVER_ADDR'];  $this->remark = C('wechat_remark');  $this->nonce_str = $this->create_nonce_str(32);  $this->api_password = C('wechat_api_password');  $inc_file = BASE_PATH.DS.'api'.DS.'wechat'.DS.'arraytoxml.php';  if(is_file($inc_file)) {   require($inc_file);  }  $this->arraytoxml = new ArrayToXML(); }  public function send_post($mch_billno,$re_openid,$total_amount){  $sign = $this->create_sign($mch_billno,$re_openid,$total_amount);  $send_array = array(   'nonce_str' => $this->nonce_str,   'mch_billno' => $mch_billno,   'mch_id' => $this->mch_id,   'wxappid' => $this->weixin_appid,   'send_name' => $this->send_name,   're_openid' => $re_openid,   'total_amount' => $total_amount,   'total_num' => $this->total_num,   'wishing' => $this->wishing,   'client_ip' => $this->client_ip,   'act_name' => $this->act_name,   'remark' => $this->remark,   'sign' => $sign,  );  $send_xml = $this->arraytoxml->toXml($send_array,'');  $data = $this->curl_post_ssl($this->url, $send_xml);  $data = $this->xmlToArray($data);  file_put_contents('adki',var_export($data,true),FILE_APPEND); } /* 请确保您的libcurl版本是否支持双向认证，版本高于7.20.1 */ private function curl_post_ssl($url, $vars, $second=30,$aHeader=array()){  $ch = curl_init();  //超时时间  curl_setopt($ch,CURLOPT_TIMEOUT,$second);  curl_setopt($ch,CURLOPT_RETURNTRANSFER, 1);  //这里设置代理，如果有的话  //curl_setopt($ch,CURLOPT_PROXY, '10.206.30.98');  //curl_setopt($ch,CURLOPT_PROXYPORT, 8080);  curl_setopt($ch,CURLOPT_URL,$url);  curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);  curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,false);  //以下两种方式需选择一种  //第一种方法，cert 与 key 分别属于两个.pem文件  //默认格式为PEM，可以注释  curl_setopt($ch,CURLOPT_SSLCERTTYPE,'PEM');  curl_setopt($ch,CURLOPT_SSLCERT,getcwd().$this->public_key);  //默认格式为PEM，可以注释  curl_setopt($ch,CURLOPT_SSLKEYTYPE,'PEM');  curl_setopt($ch,CURLOPT_SSLKEY,getcwd().$this->private_key);  //ca证书  curl_setopt($ch,CURLOPT_CAINFO,$this->rootca);  //第二种方式，两个文件合成一个.pem文件  //curl_setopt($ch,CURLOPT_SSLCERT,getcwd().'/all.pem');  if( count($aHeader) >= 1 ){   curl_setopt($ch, CURLOPT_HTTPHEADER, $aHeader);  }  curl_setopt($ch,CURLOPT_POST, 1);  curl_setopt($ch,CURLOPT_POSTFIELDS,$vars);  $data = curl_exec($ch);  if($data){   curl_close($ch);   return $data;  }  else {   $error = curl_errno($ch);   echo "call faild, errorCode:$error\n\n\n\n";   curl_close($ch);   return false;  } } //生成签名 private function create_sign($mch_billno,$re_openid,$total_amount){  $string_array = array(   'act_name' => $this->act_name,   'client_ip' => $this->client_ip,   'mch_billno' => $mch_billno,   'mch_id' => $this->mch_id,   'nonce_str' => $this->nonce_str,   're_openid' => $re_openid,   'remark' => $this->remark,   'send_name' => $this->send_name,   'total_amount' => $total_amount,   'total_num' => $this->total_num,   'wishing' => $this->wishing,   'wxappid' => $this->weixin_appid,  );  foreach ($string_array as $key => $value){   if(!empty($value)){    $stringA .= "$key=$value";    if($key != 'wxappid'){     $stringA .= '&';    }   }  }  //转成UTF-8  $stringA = $this->gbkToUtf8($stringA);  $stringSignTemp="$stringA&key=$this->api_password";  $sign = MD5($stringSignTemp);  $sign = strtoupper($sign);  return $sign; } //生成随机字符串 private function create_nonce_str($length){  $str = null;  $strPol = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789abcdefghijklmnopqrstuvwxyz";  $max = strlen($strPol)-1;  for($i=0;$i<$length;$i++){   $str.=$strPol[rand(0,$max)];//rand($min,$max)生成介于min和max两个数之间的一个随机整数  }  return $str; } /**  *自动判断把gbk或gb2312编码的字符串转为utf8  *能自动判断输入字符串的编码类，如果本身是utf-8就不用转换，否则就转换为utf-8的字符串  *支持的字符编码类型是：utf-8,gbk,gb2312  *@$str:string 字符串  */ private function gbkToUtf8($str){  $charset = mb_detect_encoding($str,array('ASCII','UTF-8','GBK','GB2312'));  $charset = strtolower($charset);  if("utf-8" != $charset){   $str = iconv('UTF-8',$charset,$str);  }  return $str; } private function xmlToArray($postStr){  $msg = array();  $msg = (array)simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);  return $msg; }}
