微信公众号主动推送消息的实现

通过学习借鉴朋友的实现方法进行整理，实现了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;  
}
