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。
//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;
}
