对于公众号内模板消息功能的使用，首先去微信公众平台开通模板消息功能，认证的时间大约是3天。认证通过后选择模板，获得消息模板ID。此功能主要用于微信公众号消息提醒，比如客户的商家认证审核通过，用户购买商品成功等功能提醒，可以有效减少网站项目开发所必要的资金节约。下面重点来讲解一下接口代码：
接口代码如下：
// 字符编码
header("Content-Type:text/html; charset=utf-8");
// 微信接口类
class Wchat{
private static $appid;
private static $appsecret;
function __construct(){
self::$appid = '';

$url_link = urlencode($url);
return "https://open.weixin.qq.com/connect/oauth2/authorize?appid=" . self::$appid . "&redirect_uri={$url_link}&response_type=code&scope=snsapi_base&state=1#Wchat_redirect";
}
// 获取TOKEN
public static function getToken(){
$urla = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" . self::$appid . "&secret=" . self::$appsecret;
$outputa = self::curlGet($urla);
$result = json_decode($outputa, true);
return $result['access_token'];
}
/**

$access_token_json = self::curlGet($access_token_url);
$access_token_array = json_decode($access_token_json, true);
$openid = $access_token_array['openid'];
$new_access_token = $weiwei_token;
//全局access token获得用户基本信息

}
- php调用接口代码
Php代码如下：
public function msg(){
require_once 'WchatAction.class.php';
// 微信接口类
$wchat = new \Wchat();
$wchat->pushMessage();
}
好了，以上就是全部的源码了，如果大家还是存在不理解的地方，可以留言咨询。
