微信支付，wxpay, jsapi,微信js-sdk 支付koa和express
###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', { "appId": "<%= args.appId %>", "timeStamp": "<%= args.timeStamp %>", "nonceStr": "<%= args.nonceStr %>", "package": "prepay_id=<%= args.package %>", "signType": "MD5", "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") { alert(res.err_msg); //成功页面 } else if (res.err_msg == "get_brand_wcpay_request:fail") { alert(res.err_msg); //成功页面 } else {
}
});
};
if (document.addEventListener) {
document.addEventListener("WeixinJSBridgeReady", onBridgeReady, true);
} else {
document.attachEvent("onWeixinJSBridgeReady", onBridgeReady);
}
// $(function(){
// addCharge();
// });
</script>
