真香:一行命令即可体验「微信支付」全系接口能力

以命令行方式与微信支付接口交互——姗姗来了,其旨在提供一种简洁高效的方式,希望能对开发者有所帮助。

你没看错,这款唯二的「Play the OpenAPI requests over command line」——「以命令行方式与微信支付接口交互」姗姗来了,旨在提供一种简洁高效的接入方式,希望能对开发者有所帮助。

nodejs版的 wechatpay-axios-plugin 已经进入v0.5版,v0.5做了这些改变:

  • 全部代码(包括265条测试用例)使用 eslint-config-airbnb-base 代码风格校验;
  • 使用 yargs 包替换了 commander,重构了「平台证书下载器」工具,使其降级为此命令行一个特殊方法;
  • 降级 form-datayargs 包为 peerDependencies,没有这俩包,90%+ 的接口是可以正常工作的,缩减依赖;
  • 新增 bin/cli.js,开发可以仅用一条命令就能跑得欢实不要不要的了;

使用

开始使用前,需要开发者自行安装cli模式依赖的npm包,即 npm i yargs

  -d.auth_code 120061098828009406

设计

主程序 bin/cli.js 上,加入了一个中间件,代码如下:

.middleware((argv) => {
  if (argv.c && argv.c.privateKey && argv.c.privateKey !== 'any') {
    /* eslint-disable-next-line no-param-reassign */
    argv.config.privateKey = readFileSync(argv.c.privateKey);
  }
  if (argv.c && argv.c.certs && Object.keys(argv.c.certs)[0] !== 'any') {
    /* eslint-disable-next-line no-return-assign, no-param-reassign, no-sequences */
    argv.config.certs = Object.entries(argv.config.certs).reduce((o, [k, v]) => (o[k] = readFileSync(v), o), {});
  }
  if (argv.c && argv.c.merchant) {
    if (argv.c.merchant.cert && argv.c.merchant.cert !== 'any') {
      /* eslint-disable-next-line no-param-reassign */
      argv.config.merchant.cert = readFileSync(argv.c.merchant.cert);
    }
    if (argv.c.merchant.key && argv.c.merchant.key !== 'any') {
      /* eslint-disable-next-line no-param-reassign */
      argv.config.merchant.key = readFileSync(argv.c.merchant.key);
    }
    if (argv.c.merchant.pfx && argv.c.merchant.pfx !== 'any') {
      /* eslint-disable-next-line no-param-reassign */
      argv.config.merchant.pfx = readFileSync(argv.c.merchant.pfx);
    }
  }
}, true)

其作用就是,把v3所需的证书以文件形式自动加载,供后续 cli/request.js方法直接使用,req方法核心代码也就10行!

handler(argv) {
  const {
    baseURL, uri, config, method, data, params, headers,
  } = argv;
  const responseType = argv.binary ? 'arraybuffer' : undefined;
  const structure = [{ params, headers, responseType }];

  if (data) { structure.unshift(data); }

  (new Wechatpay({ baseURL, ...config }))[uri][method](...structure)
    /* eslint-disable-next-line no-console */
    .then(console.info).catch(console.error);
},

Q: 哇!这么简单?
