Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

创建统一支付订单

var WXPay = require('weixin-pay');

var wxpay = WXPay({
	appid: 'xxxxxxxx',
	mch_id: '1234567890',
	partner_key: 'xxxxxxxxxxxxxxxxx', //微信商户平台API密钥
	pfx: fs.readFileSync('./wxpay_cert.p12'), //微信商户平台证书
});

var result =  yield wxpay.createUnifiedOrder({
	body: '扫码支付测试',
	out_trade_no: '20140703'+Math.random().toString().substr(2, 10),
	total_fee: 1,
	spbill_create_ip: '192.168.2.210',
	notify_url: 'http://wxpay_notify_url',
	trade_type: 'NATIVE',
	product_id: '1234567890'
});

查询订单

// 通过微信订单号查
var result =  yield wxpay.queryOrder({ transaction_id:"xxxxxx" });

// 通过商户订单号查
var result =  yield wxpay.queryOrder({ out_trade_no:"xxxxxx" });

关闭订单

var result =  yield wxpay.closeOrder({ out_trade_no:"xxxxxx"});

退款接口

var params = {
	appid: 'xxxxxxxx',
	mch_id: '1234567890',
    op_user_id: '商户号即可',
    out_refund_no: '20140703'+Math.random().toString().substr(2, 10),
    total_fee: '1', //原支付金额
    refund_fee: '1', //退款金额
    transaction_id: '微信订单号'
};

var result = yield  wxpay.refund(params);

原生支付 (NATIVE)

模式一

提供一个生成支付二维码链接的函数,把url生成二维码给用户扫。

var url = wxpay.createMerchantPrepayUrl({ product_id: '123456' });

商户后台收到微信的回调之后,调用 createUnifiedOrder() 生成预支付交易单,将结果的XML数据返回给微信。

什么是模式一?

模式二

直接调用 createUnifiedOrder() 函数生成预支付交易单,将结果中的 code_url 生成二维码给用户扫。

什么是模式二?

公众号支付 (JS API)

生成JS API支付参数,发给页面

var result = yield  wxpay.getBrandWCPayRequestParams({
	openid: '微信用户 openid',
	body: '公众号支付测试',
    detail: '公众号支付测试',
	out_trade_no: '20150331'+Math.random().toString().substr(2, 10),
	total_fee: 1,
	spbill_create_ip: '192.168.2.210',
	notify_url: 'http://wxpay_notify_url'
});

网页调用参数(以ejs为例)

WeixinJSBridge.invoke(
	"getBrandWCPayRequest", <%-JSON.stringify(payargs)%>, function(res){
		if(res.err_msg == "get_brand_wcpay_request:ok" ) {
    		// success
    	}
});

中间件

商户服务端处理微信的回调(koa为例)


app.use(function *() {
	var result = yield wxpay.parseCallbacl(this);

	// handle with callback data
	result.data;
	// ...

	// return success
	this.body = result.success;
	// return fail
	this.body = result.fail;
});

企业支付

var result = yield wxpay.transfer({
	partner_trade_no: '3123123123', // 订单号
	openid: 'openid',
	amount: 100, // 分为单位
	desc: '描述',
	spbill_create_ip: '192.168.2.210', // ip,
	check_name: 'NO_CHECK', //默认为 NO_CHECK, 可不填
});
