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-data及yargs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

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？
A: 不就是为了简单么。。。
火钳刘明。我的博客里也有很多微信支付相关的内容。还有些乱七八糟的瞎研究。
