返回的 html 乱码

网页内容格式是 GBK 和头部用 gzip 压缩，设置属性gzip: true和encoding:null，再通过 iconv 转成 utf8

npm install request
npm install iconv-lite

const request = require('request');
const iconv = require('iconv-lite');
const options = {
        url: `http://xxxx`,
        proxy: 'http://127.0.0.1:8888',
        secureProtocol: 'TLSv1_method',
        gzip: true,
        encoding: null
    };
request.get(options, function (err, response, data) {
        const result = iconv.decode(data, 'utf-8').toString();
        console.log(result);
});

返回参数乱码

去掉 encoding 参数即可

const request = require('request');
const iconv = require('iconv-lite');
const options = {
        url: `http://xxxx`,
        proxy: 'http://127.0.0.1:8888',
        secureProtocol: 'TLSv1_method',
        gzip: true
    };
request.get(options, function (err, response, data) {
        console.log(data.toString());
});

如果头部没有压缩过的，去掉 gzip 参数，然后再把返回的参数data.toString()一下
