任何人都可以从网站 www.coupang.com 得到适当的回应吗？我不断向“ https://www.coupang.com/ ”提出请求，但十次中有九次出现错误。（有时它有效！令人惊讶。）

我也尝试过使用 python3 发出请求，它工作正常。我认为我的 ruby​​ 配置或 ruby​​ 本身有问题。

require 'nokogiri'
require 'open-uri'
require 'net/http'


uri = URI("https://www.coupang.com/")
res = Net::HTTP.get_response(uri)
puts res.body if res.is_a?(Net::HTTPSuccess)

我会很感激你对这件事的好意。谢谢！

他们正在使用 akamai，所以首先 - 他们期望 HTTP/2（你需要一个 http2 gem）并且他们有一些相当严格的用户代理嗅探。

这是一个使用net-http2的示例

client = NetHttp2::Client.new "https://www.coupang.com/"
res = client.call :get, '/', headers: { "User-Agent" => "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6)" }
puts res.body if res.ok?
