微信封装的调用微信签名包的类库

这篇文章主要介绍了微信封装的调用微信签名包的类库的相关资料,需要的朋友可以参考下

废话不多说了，直接给大家贴代码了，具体代码如下所示：

<?phpnamespace HomeModel;use ThinkModel;class WechatModel extends Model {private $_token = ''; //令牌private $appid;private $appsecret;public function __construct(){$this->appid = C('APPID');//公众号的appid$this->appsecret = C('APPSECRET');//公众号的秘钥}//调用js-sdk的签名包public function getSignPackage() {$jsapiTicket = $this->getJsApiTicket();// 注意 URL 一定要动态获取，不能 hardcode.（获取当前网页的url）$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' || $_SERVER['SERVER_PORT'] == 443) ?
