微信公众号主动推送消息的实现

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;    }
