cheerio gb2312 转码问题

const iconv = require(‘iconv-lite’);

const request = require(‘request’);

headers: {
            "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8",
            "Accept-Encoding": "gzip, deflate",
            "Accept-Language": "zh-CN,zh;q=0.9",
            "Cache-Control": "no-cache",
            "Connection": "keep-alive",

            "Pragma": "no-cache",
            "Referer": "http://www.cast.net.cn/",

            "x-forwarded-for": "127.0.0.1"
        },
        encoding:null

重点，在request库中一定要设置encoding:null

lethtml=iconv.decode(body,’gb2312′)

let$=cheerio.load(html,{decodeEntities: false});
