    这是一个创建于 1270 天前的主题,其中的信息可能已经有所发展或是发生改变。
    很简单的一个事,我就是想访问 opensea ,把 html 拉下来。但是试着用 needle 和 axios 请求都会被 cloudflare 打回来,各种 header 我都加过了。
    但是神奇的就是 postman 请求永远都是成功的,你说一直不行把 我用 needle 又请求成功一次,像请问下大哥们有人遇到过这个嘛,要怎么解决

    import fs from 'node:fs/promises';
    import got from 'got';
    import needle from 'needle';

    const res = await got('https://opensea.io/', {
    responseType: 'text'
    });

    await fs.writeFile('1.html', res.body);

    needle.get('https://opensea.io/', function(error, res) {
    if (!error && res.statusCode === 200)
    fs.writeFile('2.html', res.body);
    });

    测了下没问题,应该没有反爬。有可能是网络问题,毕竟服务器在境外。
