自己编写的脚本获取的中文内容有乱码

[yetio]

我尝试参考andyt的例子写了一个论坛的脚本，运行时发现中文全部显示为乱码。我试过将编码改成gbk,gb2312,utf-8，均有乱码。请问如何解决？谢谢

const got = require('@/utils/got');
const cheerio = require('cheerio');
const iconv = require('iconv-lite');

const baseUrl = 'https://zzhzbbs.zjol.com.cn/forum.php?mod=guide&view=';
const host = 'https://zzhzbbs.zjol.com.cn/';
const viewProps = {
    newthread: 'newthread',
    hot: 'hot',
    digest: 'disgest',
    new: 'new',
};

module.exports = async (ctx) => {
    const view = ctx.params.view || 'newthread';
    const url = baseUrl + view;
    const response = await got({
        method: 'get',
        url: url,
        responseType: 'arraybuffer'
    });
    // 转码
    const data = iconv.decode(response.data, 'gb2312');
    const $ = cheerio.load(data, { decodeEntities: false } );

    ctx.state.data = {
        title: `${viewProps[view]}`,
        link: url,
        description: `${viewProps[view]}`,
        item: $('.bm_c')
            .find('tbody')
            .map((index, item) => ({
                title:
                    `【` +
                    $(item)
                        .find('td.by a')
                        .eq(0)
                        .text() +
                    `】` +
                    $(item)
                        .find('a.xst')
                        .text(),
                description: '',
                author: $(item)
                    .find('cite')
                    .text()
                    .trim(),
                link:
                    host +
                    $(item)
                        .find('a')
                        .eq(0)
                        .attr('href'),
            }))
            .get(),
    };
};

    const response = await got.get(url, {
        responseType: 'buffer',
    });
    const data = iconv.decode(response.data, 'gb2312');
    const $ = cheerio.load(data);
