比较想知道 如何 re.send 发送的中文不乱码 iconv这个 东西 都不知道在哪用
https://www.npmjs.com/package/iconv-lite#extend-node-js-own-encodings
// After this call all Node basic primitives will understand iconv-lite encodings.
// 调用完该方法，所有 node 的内置原生对象会明白 iconv-lite 的编码。换言之 iconv-lite 会增加原生的编码类型。
iconv.extendNodeEncodings();
// External modules are also supported (if they use Node primitives, which they probably do).
// 同时支持外部模块（如果类库使用NODE原生对象，一般情况下都是使用原生对象）。简单来讲你反正调用上面那个方法，就在APP的范围内全局扩展编码类型。
request = require('request');
