cpay v0.0.4

微信/支付宝支付 For Typescript Express

使用Typescript语法开发基于Express框架的支付组件

安装

$ npm i cpay 

使用

import cPay from 'cpay';

Express简单架构

const Express = require('express'),
    bodyParser = require('body-parser'),
    app = new Express(),
    xmlparser = require('express-xml-bodyparser');

app.use(bodyParser.json({ limit: "500000kb" }));
app.use(bodyParser.urlencoded({ extended: true }));
app.use(xmlparser());

微信支付基础API

查询订单

let paydata = new cPay.Model.WxPayData(), orderinfo;
paydata.SetValue("out_trade_no", "商户订单号");
orderinfo = await cPay.BaseApi.OrderQuery(paydata);

撤销订单

let paydata = new cPay.Model.WxPayData(), orderinfo;
paydata.SetValue("out_trade_no", "商户订单号");
orderinfo = await cPay.BaseApi.CloseOrder(paydata);

申请退款

let paydata = new cPay.Model.WxPayData(), orderinfo;
paydata.SetValue("out_refund_no", "商户退款单号");
paydata.SetValue("out_trade_no", "商户订单号");
paydata.SetValue("refund_fee", "退款金额：订单总金额，单位为分，只能为整数");
paydata.SetValue("op_user_id", "操作员");
paydata.SetValue("total_fee", "订单金额：订单总金额，单位为分，只能为整数");
orderinfo = await cPay.BaseApi.Refund(paydata);

查询退款

let paydata = new cPay.Model.WxPayData(), orderinfo;
paydata.SetValue("out_refund_no", "商户退款单号");
orderinfo = await cPay.BaseApi.RefundQuery(paydata);

短链接生成

let paydata = new cPay.Model.WxPayData(), orderinfo;
paydata.SetValue("long_url", "需要转换的URL，传输需URL encode");
orderinfo = await cPay.BaseApi.ShortUrl(paydata);

公众号发起网页授权

app.get('/auth', async function (req: any, res: any, next: any) {
    let ojsapipay = new cPay.JsApiPay(req, res, next);
    await ojsapipay.GetWeixinUserInfo('网页应用回调地址', "是否是静默授权，Boolean类型");
    // 打印微信用户信息
    console.log(ojsapipay.WeixinUserInfo);
});

微信开放平台

开放平台代替公众号发起网页授权

• 方式一：回调地址如果为当前路由地址

weixin.Redirect_uri="http://开放平台设置的域名/open/getwxinfo";
app.get('/open/getwxinfo', async function (req: any, res: any, next: any) {
    let ojsapipay = new cPay.AccountWebsiteAuth(req, res, next);
    let wxinfo = await ojsapipay.GetWeixinUserInfo("wx97e377b7691b236a");
    console.log(wxinfo);
    console.log(ojsapipay.WeixinUserInfo);
});

• 方式二：回调地址和发起请求地址不一样

weixin.Redirect_uri="http://开放平台设置的域名/wechat/authorize-code";
app.get('/open/getwxinfo', async function (req: any, res: any, next: any) {
    let ojsapipay = new cPay.AccountWebsiteAuth(req, res, next);
    let wxinfo = await ojsapipay.GetWeixinUserInfo("wx97e377b7691b236a");
});

app.get('/wechat/authorize-code', async function (req: any, res: any, next: any) {
   let ojsapipay = new cPay.AccountWebsiteAuth(req, res, next);
    let wxinfo = await ojsapipay.GetWeixinUserInfoFromCode("wx97e377b7691b236a");
    console.log(wxinfo);
    console.log(ojsapipay.WeixinUserInfo);
});

开放平台代替公众号使用JSSDK

在申请第三方平台时填写的网页开发域名，将作为旗下授权公众号的 JS SDK 安全域名（详情见“接入前必读”-“申请资料说明”） 最多可设置三个，用“;”隔开

// 服务端
app.get('/jssdk', async function (req: any, res: any, next: any) {
    let jssdk = new cPay.JssdkSign();
    let data = await jssdk.GetJSSDK('公众号APPID','当前需要使用JSSDK的页面地址');
    // 输出参数到模版jssdk
    res.render('jssdk', { data: data });
});

关于JSSDK基于Jquery常用方法封装组件，请到NPM包微信JSSDK查看。注意！此组件不在维护，如有需要自行下载修改源码！

// 客户端
<script src="http://res2.wx.qq.com/open/js/jweixin-1.6.0.js"></script>

<script>
    wx.config({
        debug: true, // 开启调试模式,调用的所有api的返回值会在客户端alert出来，若要查看传入的参数，可以在pc端打开，参数信息会通过log打出，仅在pc端时才会打印。
        appId: '<%= data.appid%>', // 必填，公众号的唯一标识
        timestamp: '<%= data.timestamp %>', // 必填，生成签名的时间戳
        nonceStr: '<%= data.noncestr%>', // 必填，生成签名的随机串
        signature: '<%= data.signature%>',// 必填，签名
        jsApiList: ["scanQRCode"] // 必填，需要使用的JS接口列表
    });

    wx.ready(function () {
        // config信息验证后会执行ready方法，所有接口调用都必须在config接口获得结果之后，config是一个客户端的异步操作，所以如果需要在页面加载时就调用相关接口，则须把相关接口放在ready函数中调用来确保正确执行。对于用户触发时才调用的接口，则可以直接调用，不需要放在ready函数中。
        console.log('OK');
    });
    wx.error(function (res) {
        // config信息验证失败会执行error函数，如签名过期导致验证失败，具体错误信息可以打开config的debug模式查看，也可以在返回的res参数中查看，对于SPA可以在这里更新签名。
        console.log('error');
    });

    function Scan() {
        wx.scanQRCode({
            needResult: 0, // 默认为0，扫描结果由微信处理，1则直接返回扫描结果，
            scanType: ["qrCode", "barCode"], // 可以指定扫二维码还是一维码，默认二者都有
            success: function (res) {
                var result = res.resultStr; // 当needResult 为 1 时，扫码返回的结果
                console.log(result);
            }
        });
    }
</script>

<button onclick="Scan()" style="width: 150px; height: 40px; background-color: beige;">
    扫一扫
</button>
