如何使用？

       var WxPay = require("wxpay-jsapi");
       var opt = {
          appid: "appid",
          mch_id: "mch_id",
          key: "key",
          notify_url: "notify_url"
       };
       var wxpay = new WxPay(opt);
       var attach = "这里是需要传送得数据";
       var body = "这里是描述";
       var openid = "openid";
       var bookingNo = "20150806125346";//订单号长度有限制具体看微信API文档
       var total_fee = 10;//0.1元
    	 var ip = '127.0.0.1';
       wxpay.order(attach, body, openid, bookingNo, total_fee, ip).then(function(data){
          res.render('wxpay', {args: data});
       });
       

页面调用例子

    		<script type="text/javascript">
            var onBridgeReady = function() {
             WeixinJSBridge.invoke('getBrandWCPayRequest', {

             	"paySign": "<%= args.paySign %>",
             },
             function(res) {
               if (res.err_msg == "get_brand_wcpay_request:ok") {
    				alert(res.err_msg); //成功页面
               } else if (res.err_msg == "get_brand_wcpay_request:cancel") {

               } else {
                 
               }
             });
            };
            if (document.addEventListener) {
             document.addEventListener("WeixinJSBridgeReady", onBridgeReady, true);
            } else {
             document.attachEvent("onWeixinJSBridgeReady", onBridgeReady);
            }
       //      $(function(){
