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 = '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;  }
