支付

cool-admin 自带封装了微信和支付宝支付

微信支付

1、安装插件

npm install @cool-midway/pay

2、引入插件

src/configuration.ts

import { App, Configuration } from '@midwayjs/decorator';
import { ILifeCycle, IMidwayContainer } from '@midwayjs/core';
import { Application } from 'egg';
import * as orm from '@midwayjs/orm';
import * as cool from '@cool-midway/core';
import * as pay from '@cool-midway/pay';

@Configuration({
  // 注意组件顺序 cool 有依赖orm组件， 所以必须放在，orm组件之后 cool的其他组件必须放在cool 核心组件之后
  imports: [
    pay,
  ],
})
export class ContainerLifeCycle {
  @App()
  app: Application;
  // 应用启动完成
  async onReady(container?: IMidwayContainer) {}
  // 应用停止
  async onStop() {}
}

3、配置

也可以在src/config/xxx.ts配置(两种配置都存在，此种方式优先)

config.cool = {
  pay:{
    wx: {
        appid: '公众号ID',
        mchid: '微信商户号',
        partnerKey: '微信支付安全密钥',
        publicKey: require('fs').readFileSync('公钥证书文件路径'),
        privateKey: require('fs').readFileSync('私钥证书文件路径'),
        notify_url: '支付回调地址',
        key: '可选参数 APIv3密钥'
    },
  }
};

4、API

其他支付方式可以参考wechatpay-node-v3open in new window

支付宝支付

1、安装插件

@cool-midway/pay

2、引入插件

src/configuration.ts

import { App, Configuration } from '@midwayjs/decorator';

import { Application } from 'egg';
import * as orm from '@midwayjs/orm';
import * as cool from '@cool-midway/core';
import * as pay from '@cool-midway/pay';

@Configuration({
  // 注意组件顺序 cool 有依赖orm组件， 所以必须放在，orm组件之后 cool的其他组件必须放在cool 核心组件之后
  imports: [
    pay,
  ],
})
export class ContainerLifeCycle {
  @App()
  app: Application;
  // 应用启动完成
  async onReady(container?: IMidwayContainer) {}
  // 应用停止
  async onStop() {}
}

3、配置

也可以在src/config/xxx.ts配置(两种配置都存在，此种方式优先)

config.cool = {
    pay: {
      ali: {
        notifyUrl: 'https://xxx/app/order/pay/aliNotify',
        appId: 'xxxxxx',
        privateKey: fs.readFileSync(
          path.resolve('./src/modules/order/pem/ali/privateKey.pem'),
          'ascii'
        ),
        keyType: 'PKCS1',
        appCertPath: path.resolve(
          './src/modules/order/pem/ali/appCertPublicKey.crt'
        ),
        alipayRootCertPath: path.resolve(
          './src/modules/order/pem/ali/alipayRootCert.crt'
        ),
        alipayPublicCertPath: path.resolve(
          './src/modules/order/pem/ali/alipayCertPublicKey_RSA2.crt'
        ),
      },
    },
}

WARNING

注意私钥需要用支付宝密钥工具转成PKCS1格式

4、API

其他支付方式可以参考alipay-sdkopen in new window

Controller，需要注意开放回调接口，不要对其进行token校验

import {
  CoolController,
  BaseController,
  CoolUrlTag,
  TagTypes,
} from '@cool-midway/core';
import { Body, Inject, Post } from '@midwayjs/core';
import { OrderPayService } from '../../service/pay';

/**
 * 支付
 */
@CoolUrlTag({
  key: TagTypes.IGNORE_TOKEN,
  value: ['wxNotify', 'aliNotify'],
})
@CoolController()
export class AppOrderPayController extends BaseController {
  @Inject()
  orderPayService: OrderPayService;

  @Post('/aliNotify', { summary: '支付宝支付回调通知' })
  async aliNotify(@Body() body) {
    this.orderPayService.aliNotify(body);
    return 'success';
  }

  @Post('/aliQrcode', { summary: '支付宝扫码支付' })
  async aliQrcode(
    @Body('orderId') orderId: number,
    @Body('width') width: number
  ) {
    return this.ok(await this.orderPayService.aliQrcode(orderId, width));
  }

  @Post('/aliApp', { summary: '支付宝APP支付' })
  async aliApp(@Body('orderId') orderId: number) {
    return this.ok(await this.orderPayService.aliApp(orderId));
  }

  @Post('/wxApp', { summary: '微信APP支付' })
  async wxApp(@Body('orderId') orderId: number) {
    return this.ok(await this.orderPayService.wxApp(orderId));
  }

  @Post('/wxNotify', { summary: '微信支付回调' })
  async wxNotify(@Body() body) {
    await this.orderPayService.wxNotify(body);
    return 'success';
  }
