微信公众号主动推送消息的实现

代码如下：
一、http://www.php.cn/php/php-TVOS-denglu.html" target="_blank">登录接口部分代码

 //登录  
 private function login(){    
   $url = &＃39;https://mp.weixin.qq.com/cgi-bin/login?lang=zh_CN&＃39;;    
   $this->send_data = array(
     &＃39;username&＃39; => $this->_account,
      &＃39;pwd&＃39; => md5($this->_password),
      &＃39;f&＃39; => &＃39;json&＃39;
    );
    $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(&＃39;/"ErrCode": (.*)/i&＃39;, $value,$match)){//获取token
        switch ($match[1]) {
          case -1:
            die(json_encode(array(&＃39;status&＃39;=>1,&＃39;errCode&＃39;=>$match[1],&＃39;msg&＃39;=>"系统错误")));
          case -2:
            die(json_encode(array(&＃39;status&＃39;=>1,&＃39;errCode&＃39;=>$match[1],&＃39;msg&＃39;=>"帐号或密码错误")));
          case -3:
            die(urldecode(json_encode(array(&＃39;status&＃39;=>1,&＃39;errCode&＃39;=>$match[1],&＃39;msg&＃39;=>urlencode("密码错误")))));
          case -4:
            die(json_encode(array(&＃39;status&＃39;=>1,&＃39;errCode&＃39;=>$match[1],&＃39;msg&＃39;=>"不存在该帐户")));
          case -5:
            die(json_encode(array(&＃39;status&＃39;=>1,&＃39;errCode&＃39;=>$match[1],&＃39;msg&＃39;=>"访问受限")));
          case -6:
            die(json_encode(array(&＃39;status&＃39;=>1,&＃39;errCode&＃39;=>$match[1],&＃39;msg&＃39;=>"需要输入验证码")));
          case -7:
            die(json_encode(array(&＃39;status&＃39;=>1,&＃39;errCode&＃39;=>$match[1],&＃39;msg&＃39;=>"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(&＃39;status&＃39;=>1,&＃39;errCode&＃39;=>$match[1],&＃39;msg&＃39;=>"邮箱已存在")));
          case -32:
            die(json_encode(array(&＃39;status&＃39;=>1,&＃39;errCode&＃39;=>$match[1],&＃39;msg&＃39;=>"验证码输入错误")));
          case -200:
            die(json_encode(array(&＃39;status&＃39;=>1,&＃39;errCode&＃39;=>$match[1],&＃39;msg&＃39;=>"因频繁提交虚假资料，该帐号被拒绝登录")));
          case -94:
            die(json_encode(array(&＃39;status&＃39;=>1,&＃39;errCode&＃39;=>$match[1],&＃39;msg&＃39;=>"请使用邮箱登陆")));
          case 10:
            die(json_encode(array(&＃39;status&＃39;=>1,&＃39;errCode&＃39;=>$match[1],&＃39;msg&＃39;=>"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(&＃39;/^set-COOKIE:[\s]+([^=]+)=([^;]+)/i&＃39;, $value,$match)){//获取COOKIE
        $this->COOKIE .=$match[1].&＃39;=&＃39;.$match[2].&＃39;; &＃39;;
      }
      if(preg_match(&＃39;/"ErrMsg"/i&＃39;, $value,$match)){//获取token
        $this->token = rtrim(substr($value,strrpos($value,&＃39;=&＃39;)+1),&＃39;",&＃39;);
      }
    }
  }

二、信息发送部分代码

 //单发消息
  private function send($fakeid,$content){    
     $url = &＃39;https://mp.weixin.qq.com/cgi-bin/singlesend?t=ajax-response&lang=zh_CN&＃39;;    
     $this->send_data = array(
             &＃39;type&＃39; => 1,
            &＃39;content&＃39; => $content,
            &＃39;error&＃39; => &＃39;false&＃39;,
            &＃39;tofakeid&＃39; => $fakeid,
            &＃39;token&＃39; => $this->token,
            &＃39;ajax&＃39; => 1,
          );
          $this->referer = &＃39;https://mp.weixin.qq.com/cgi-bin/singlemsgpage?token=&＃39;.$this->token.&＃39;&fromfakeid=&＃39;.$fakeid.&＃39;&msgid=&source=&count=20&t=wxm-singlechat&lang=zh_CN&＃39;;    
          return $this->curlPost($url);  
     }

三、群发信息代码

  //群发消息
  public function sendMessage($cOntent=&＃39;&＃39;,$userId=&＃39;&＃39;) {
    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($v[&＃39;fakeid&＃39;],$content));
        if($json->ret!=0){
          $errUser[] = $v[&＃39;fakeid&＃39;];
        }
      }
    }
     
    //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;
     
    $data = array(
      &＃39;status&＃39;=>0,
      &＃39;count&＃39;=>$count,
      &＃39;succeCount&＃39;=>$succeCount,
      &＃39;errCount&＃39;=>$errCount,
      &＃39;errUser&＃39;=>$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[&＃39;groupid&＃39;],$v[&＃39;fakeid&＃39;]);
    }
     
    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;    
      $this->referer = &＃39;https://mp.weixin.qq.com/cgi-bin/contactmanagepage?token=&＃39;.$this->token.&＃39;&t=wxm-friend&lang=zh_CN&pagesize=&＃39;.$this->pageSize.&＃39;&pageidx=0&type=0&groupid=&＃39;.$groupId;    
      $this->send_data = array(      
         &＃39;token&＃39;=>$this->token,      
         &＃39;ajax&＃39;=>1    );    
      $message_opt = $this->curlPost($url);    
      return $message_opt;  
   }
   //获取所有用户fakeid
  private function getUserFakeid(){
    ini_set(&＃39;max_execution_time&＃39;,600);
    $pageSize = 1000000;
    $this->referer = "https://mp.weixin.qq.com/cgi-bin/home?t=home/index&lang=zh_CN&token={$_SESSION[&＃39;token&＃39;]}";
    $url = "https://mp.weixin.qq.com/cgi-bin/contactmanage?t=user/index&pagesize={$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){      
       $url = &＃39;https://mp.weixin.qq.com/cgi-bin/contactmanage?t=user/index&pagesize=&＃39;.$pageSize.&＃39;&pageidx=0&type=0&groupid=&＃39;.$v.&＃39;&token=&＃39;.$this->token.&＃39;&lang=zh_CN&＃39;;      
       $user = $this->vget($url);      
       $preg = "/\"id\":(\d+),\"nick_name\"/";      
       preg_match_all($preg,$user,$a);      
       foreach($a[1] as $vv){        
         $arr[$i][&＃39;fakeid&＃39;] = $vv;       
         $arr[$i][&＃39;groupid&＃39;] = $v;        
         $i++;      
          }   
    }    
    return $arr;  
}
