php实现微信推送消息

一.
<?php
namespace Org\Weixin;

class OrderPush
{
    protected $appid;
    protected $secrect;
    protected $accessToken;
    function  __construct($appid, $secrect)
    {
        $this->appid = $appid;
        $this->secrect = $secrect;
        $this->accessToken = $this->getToken($appid, $secrect);
    }
    /**
     * 发送post请求
     * @param string $url
     * @param string $param
     * @return bool|mixed
     */
    function request_post($url = '', $param = '')
    {
        if (empty($url) || empty($param)) {
            return false;
        }
        $postUrl = $url;
        $curlPost = $param;
        $ch = curl_init(); //初始化curl
        curl_setopt($ch, CURLOPT_URL, $postUrl); //抓取指定网页
        curl_setopt($ch, CURLOPT_HEADER, 0); //设置header
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); //要求结果为字符串且输出到屏幕上
        curl_setopt($ch, CURLOPT_POST, 1); //post提交方式
        curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);
        $data = curl_exec($ch); //运行curl
        curl_close($ch);
        return $data;
    }
    /**
     * 发送get请求
     * @param string $url
     * @return bool|mixed
     */
    function request_get($url = '')
    {
        if (empty($url)) {
            return false;
        }
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $data = curl_exec($ch);
        curl_close($ch);
        return $data;
    }
    /**
     * @param $appid
     * @param $appsecret
     * @return mixed
     * 获取token
     */
    protected function getToken($appid, $appsecret)
    {
        if (S($appid)) {
            $access_token = S($appid);
        } else {
            $url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&app . $this->accessToken;
        $dataRes = $this->request_post($url, urldecode($json_template));
        if ($dataRes['errcode'] == 0) {
            return true;
        } else {
            return false;
        }
    }
}

二、

public function http_request($url,$data)
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
    $output = curl_exec($ch);
    curl_close($ch);
    return $output;
}

public function moban($name, $zu, $remain, $openid)
{
    $appid = "";       //填写微信后台的appid
    $appsecret = "";   //填写微信后台的appsecret
    //从数据库查看access_token
    $sql = "SELECT * FROM `tokentime` WHERE id='$appid'";
    $query = mysql_query($sql);
    $rk = mysql_fetch_array($query);
    $time = date('Y-m-d H:i:s', time());
    if ($rk == "")   //数据库查询无结果 获取access_token并存入
    {
        $TOKEN_URL = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&app . $ACCESS_TOKEN;
    $res = http_request($url, urldecode($json_template));
    if ($res[errcode] == 0) echo '消息发送成功!';
}
