php实现微信公众号主动推送消息

通过学习借鉴朋友的实现方法进行整理，实现了PHP版的微信公共平台消息主动推送，分享给大家供大家参考，具体内容如下
此方法是通过模拟登录微信公共平台的方法来实现的。
代码如下：
一、登录接口部分代码

 //登录
 private function login(){
   $url = 'https://mp.weixin.qq.com/cgi-bin/login?lang=zh_CN';
   $this->send_data = array(
     'username' => $this->_account,
     'pwd' => md5($this->_password),
     'f' => 'json'
   );
   $this->referer = "https://mp.weixin.qq.com/";
   $this->getHeader = 1;
   $result = explode("\n",$this->curlPost($url));
   foreach ($result as $key => $value) {
     $value = trim($value);
     if(preg_match('/"ErrCode": (.*)/i', $value,$match)){//获取token
       switch ($match[1]) {
         case -1:
           die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"系统错误")));
         case -2:
           die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"帐号或密码错误")));
         case -3:
           die(urldecode(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>urlencode("密码错误")))));
         case -4:
           die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"不存在该帐户")));
         case -5:
           die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"访问受限")));
         case -6:
           die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"需要输入验证码")));
         case -7:
           die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"此帐号已绑定私人微信号，不可用于公众平台登录")));
         case -8:
           die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"邮箱已存在")));
         case -32:
           die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"验证码输入错误")));
         case -200:
           die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"因频繁提交虚假资料，该帐号被拒绝登录")));
         case -94:
           die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"请使用邮箱登陆")));
         case 10:
           die(json_encode(array('status'=>1,'errCode'=>$match[1],'msg'=>"该公众会议号已经过期，无法再登录使用")));
         case 0:
           $this->userFakeid = $this->getUserFakeid();
           break;
       }
     }
     if(preg_match('/^set-cookie:[\s]+([^=]+)=([^;]+)/i', $value,$match)){//获取cookie
       $this->cookie .=$match[1].'='.$match[2].'; ';
     }
     if(preg_match('/"ErrMsg"/i', $value,$match)){//获取token
       $this->token = rtrim(substr($value,strrpos($value,'=')+1),'",');
     }
   }
 }

二、信息发送部分代码

 //单发消息
 private function send($fakeid,$content){
   $url = 'https://mp.weixin.qq.com/cgi-bin/singlesend?t=ajax-response&lang=zh_CN';
   $this->send_data = array(
       'type' => 1,
       'content' => $content,
       'error' => 'false',
       'tofakeid' => $fakeid,
       'token' => $this->token,
       'ajax' => 1,
     );
   $this->referer = 'https://mp.weixin.qq.com/cgi-bin/singlemsgpage?token='.$this->token.'&fromfakeid='.$fakeid.'&msgid=&source=&count=20&t=wxm-singlechat&lang=zh_CN';
   return $this->curlPost($url);
 }

三、群发信息代码

 //群发消息
 public function sendMessage($content='',$userId='') {
   if(is_array($userId) && !empty($userId)){
     foreach($userId as $v){
       $json = json_decode($this->send($v,$content));
       if($json->ret!=0){
         $errUser[] = $v;
       }
     }
   }else{
     foreach($this->userFakeid as $v){
       $json = json_decode($this->send($v['fakeid'],$content));
       if($json->ret!=0){
         $errUser[] = $v['fakeid'];
       }
     }
   }

//共发送用户数
   $count = count($this->userFakeid);
   //发送失败用户数
   $errCount = count($errUser);
   //发送成功用户数
   $succeCount = $count-$errCount;

$data = array(
     'status'=>0,
     'count'=>$count,
     'succeCount'=>$succeCount,
     'errCount'=>$errCount,
     'errUser'=>$errUser
   );

return json_encode($data);
 }

四、获取所有用户信息代码片段

 //获取所有用户信息
 public function getAllUserInfo(){
   foreach($this->userFakeid as $v){
     $info[] = $this->getUserInfo($v['groupid'],$v['fakeid']);
   }

return $info;
 }

//获取用户信息
 public function getUserInfo($groupId,$fakeId){
   $url = "https://mp.weixin.qq.com/cgi-bin/getcontactinfo?t=ajax-getcontactinfo&lang=zh_CN&fakeid={$fakeId}";
   $this->getHeader = 0;
   $this->referer = 'https://mp.weixin.qq.com/cgi-bin/contactmanagepage?token='.$this->token.'&t=wxm-friend&lang=zh_CN&pagesize='.$this->pageSize.'&pageidx=0&type=0&groupid='.$groupId;
   $this->send_data = array(
     'token'=>$this->token,
     'ajax'=>1
   );
   $message_opt = $this->curlPost($url);
   return $message_opt;
 }

//获取所有用户fakeid
 private function getUserFakeid(){
   ini_set('max_execution_time',600);
   $pageSize = 1000000;
   $this->referer = "https://mp.weixin.qq.com/cgi-bin/home?t=home/index&lang=zh_CN&token={$_SESSION['token']}";
   $url = "https://mp.weixin.qq.com/cgi-bin/contactmanage?t=user/index&pagesize={$pageSize}&pageidx=0&type=0&groupid=0&token={$this->token}&lang=zh_CN";
   $user = $this->vget($url);
   $preg = "/\"id\":(\d+),\"name\"/";
   preg_match_all($preg,$user,$b);
   $i = 0;
   foreach($b[1] as $v){
     $url = 'https://mp.weixin.qq.com/cgi-bin/contactmanage?t=user/index&pagesize='.$pageSize.'&pageidx=0&type=0&groupid='.$v.'&token='.$this->token.'&lang=zh_CN';
     $user = $this->vget($url);
     $preg = "/\"id\":(\d+),\"nick_name\"/";
     preg_match_all($preg,$user,$a);
     foreach($a[1] as $vv){
       $arr[$i]['fakeid'] = $vv;
       $arr[$i]['groupid'] = $v;
       $i++;
     }
   }
   return $arr;
 }
