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 = "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;    $result = explode("",$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;  }
