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 = '';

}

// 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

公众号消息推送

'template_id' => "", // 填写你自己的消息模板ID

'data' => [ // 模板消息内容，根据模板详情进行设置

],

'url' => 'http://www.xxxx.com/Shop/info?id='.$id // 消息跳转链接

]);

}

2. 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();

}
