ruby - 无法通过 Ruby 获得 URL 响应

Question

我在 Ruby 中连接到下面列出的 URL 时出错，即使该 URL 存在。这是为什么？

1.9.3p194 :003 > require 'uri'
 => true 
1.9.3p194 :004 > require 'net/http'
 => true 
1.9.3p194 :005 > url = "https://blogs.oracle.com/ksplice/entry/introducing_redpatch"
 => "https://blogs.oracle.com/ksplice/entry/introducing_redpatch" 
1.9.3p194 :006 > url_parsed = URI.parse(url)
 => #<URI::HTTPS:0x00000001939288 URL:https://blogs.oracle.com/ksplice/entry/introducing_redpatch> 
1.9.3p194 :007 > response = Net::HTTP.get_response(url_parsed)
Errno::ECONNRESET: Connection reset by peer

Answer 1

用这个

url = "https://blogs.oracle.com/ksplice/entry/introducing_redpatch"
uri = URI.parse(url)
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE

request = Net::HTTP::Get.new(uri.request_uri)

response = http.request(request)
response.body

它取自这里：http ://www.rubyinside.com/nethttp-cheat-sheet-2940.html

Answer 2

与其使用 Net::HTTP，不如简化您的生活并使用 Ruby 的OpenURI。除非您需要低级控制或低级值的可见性，否则您会发现 OpenURI 已经足够好：

require 'open-uri'
url = "https://blogs.oracle.com/ksplice/entry/introducing_redpatch"
open(url).read.size
=> 35493
