ThinkPHP5微信模板消息推送

1,在微信公众平台申请模板消息

2,在ThinkPHP5项目里application文件下新建tools文件夹然后在里面写微信模板消息推送类

<?php
/**
 * 微信模板消息推送类
 * Pasa吴
 * 2019年1月22日16:21:01
 */
namespace app\tools;

use think\Cache;
use think\Controller;

class WeChatPush extends Controller
{
    //微信公众号appid
    protected $appid;
    //微信公众号secret
    protected $secret;
    /**

     * [__construct description]

     * @DateTime 2019-01-22T16:39:56+0800
     * @param    [type]                   $appid  [微信公众号appid]
     * @param    [type]                   $secret [微信公众号secret]
     */
    public function __construct($appid, $secret)
    {
        $this->appid  = $appid;
        $this->secret = $secret;
    }
    /**

     * @return   [type]                                [description]
     */
    public function push($openid, $template_id, $url, $_data)
    {
        //提交成功，触发信息推送
        $data = [
            'touser'      => $openid,
            'template_id' => $template_id,
            'url'         => $url,
            'topcolor'    => "#FF0000",
            'data'        => $_data,
        ];
        $get_all_access_token = $this->getAllAccessToken();
        $json_data            = json_encode($data); //转化成json数组让微信可以接收

        $res = $this->curlRequest($url, urldecode($json_data)); //请求开始
        $res = json_decode($res, true);
        return $res;
    }
    /**

     */
    public function getAllAccessToken()
    {
        $wxTokenUrl = 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=' . $this->appid . '&secret=' . $this->secret;

        if (!Cache::get('access_token')) {

            $access_token = json_decode($access_token, true);
            if (!empty($access_token['errcode'])) {
                // var_dump(['code'=>2004,'msg'=>'请求微信服务器access_token失败']);
                return;
            }
            Cache::set('access_token', $access_token['access_token'], 7000);
        } else {

    }
    /**

    public function curlRequest($url, $data = null, $type = 1)
    {

        curl_setopt($curl, CURLOPT_URL, $url);
        curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
        if (!empty($data)) {
            curl_setopt($curl, CURLOPT_POST, 1);
            curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
            if ($type == 2) {
                curl_setopt($curl, CURLOPT_HTTPHEADER,
                    array('Content-Type: application/json', 'Content-Length: ' . strlen($data)));
            }
        }
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

        $output = curl_exec($curl);
        curl_close($curl);
        return $output;
    }
}

3，调用push发送推送方法

<?php
namespace app\api\Controller;
//引入 微信模板消息推送类
use app\tools\WeChatPush;
use think\Controller;

class Test extends Controller
{
    public function test()
    {    
        //new 类
        $WeChatPush = new WeChatPush('公众号appid', '公众号secret');
        //模板内容(字段对应你申请的模板字段)
        $data       = array(
            'first'    => array('value' => urlencode("您好,您发布的项目"), 'color' => "#743A3A"),
            'keyword1' => array('value' => urlencode("审核通过"), 'color' => '#743A3A'),
            'keyword2' => array('value' => urlencode(date('Y-m-d H:i:s', time())), 'color' => '#743A3A'),
            'remark'   => array('value' => urlencode('请随时关注站内消息！'), 'color' => '#743A3A'),
        );
        //调用发送推送方法
        $result = $WeChatPush->push('用户openid', "模板id", "跳转URL",$data);
        var_dump($result);die;
    }
}
