Implementation of WeChat public account actively pushing messages

By learning from friends’ implementation methods and sorting them out, the WeChat public platform messages are actively pushed and shared with everyone for your reference. The specific content is as follows
This method is implemented by simulating the method of logging in to the WeChat public platform.

The code is as follows:
1.Login InterfacePart of the code

 //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),'",');
      }
    }
  }

2. Part of the code for sending information

 //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);  
     }

3. Code for group messaging

  //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);
  }

4. Code fragment for obtaining all user information

  //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;  
}
