php实现微信公众号主动推送消息

　　通过学习借鉴朋友的实现方法进行整理，实现了PHP版的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，更多消息请关注应届毕业生网。

　　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 = '//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 = "//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 = '//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,
      );
    $this->referer = '//mp.weixin.qq.com/cgi-bin/singlemsgpage?token='.$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){

$url = "//mp.weixin.qq.com/cgi-bin/getcontactinfo?t=ajax-getcontactinfo&lang=zh_CN&fakeid={$fakeId}";

$this->getHeader = 0;

$this->referer = '//mp.weixin.qq.com/cgi-bin/contactmanagepage?token='.$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;

$this->referer = "//mp.weixin.qq.com/cgi-bin/home?t=home/index&lang=zh_CN&token={$_SESSION['token']}";

$url =

"//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){

$url = '//mp.weixin.qq.com/cgi-bin/contactmanage?t=user/index&pagesize='.$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;

}

　　希望本文所述对大家学习php程序设计有所帮助。
