    async pay() {

        // this.ctx.body='支付宝支付';


        var d = new Date();
        const data = {
            subject: '辣条111',
            out_trade_no: d.getTime().toString(),

        }

        var url = await this.service.alipay.doPay(data);

        this.ctx.redirect(url);

    }

service

app/service/alipay.js

    async doPay(orderData, ) {


        return new Promise((resolve, reject) => {

            //实例化 alipay
            const service = new Alipay(this.config.alipayOptions);

            //获取返回的参数
            // this.config.alipayBasicParams

            service.createPageOrderURL(orderData, this.config.alipayBasicParams)
                .then(result => {
                    console.log(result);
                    resolve(result.data);

                })
        })


    }

支付后

支付后跳转的地址

controller

app/controller/default/alipay.js

    async alipayReturn() {


        this.ctx.body = '支付成功';

        //接收异步通知        
    }

支付宝支付成功异步通知

引入koa-xml-body解析支付成功后的回调xml格式数据

app/middleware/xmlparse.js

module.exports = require('koa-xml-body');

controller

支付成功以后更新订单 必须正式上线

app/controller/default/alipay.js

    async alipayNotify() {

        const params = this.ctx.request.body; //接收 post 提交的 XML 

        console.log(params);

        var result = await this.service.alipay.alipayNotify(params);

        console.log('-------------');

        console.log(result);


        if (result.code == 0) {
            if (params.trade_status == 'TRADE_SUCCESS') {
                //更新订单
            }
        }

        //接收异步通知
    }

service

验证异步通知的数据是否正确

app/service/alipay.js

    alipayNotify(params) {

        //实例化 alipay
        const service = new Alipay(this.config.alipayOptions);

        return service.makeNotifyResponse(params);


    }
