require 'net/http'
require 'uri'
Net::HTTP.get_print URI.parse('https://forums.malwarebytes.org/index.php?showtopic=49893')

我收到如下错误:: c：/ruby/lib/ruby/1.8/net/protocol.rb：133：在sysread': end of file reached (EOFError) from c:/ruby/lib/ruby/1.8/net/protocol.rb:133:in rbuf_fill'中来自c：/ruby/lib/ruby/1.8/timeout.rb:56:in timeout' from c:/ruby/lib/ruby/1.8/timeout.rb:76:in timeout' 来自c：/ruby/lib/ruby/1.8/net/protocol.rb:132:in rbuf_fill' from c:/ruby/lib/ruby/1.8/net/protocol.rb:116:in readuntil' 来自c：/ruby/lib/ruby/1.8/net/protocol.rb:126:in readline' from c:/ruby/lib/ruby/1.8/net/http.rb:2029:in read_status_line' 来自c：/ruby/lib/ruby/1.8/net/http.rb:2018：在read_new' from c:/ruby/lib/ruby/1.8/net/http.rb:1059:in请求中来自c：/ruby/lib/ruby/1.8/net/http.rb：957：in request_get' from c:/ruby/lib/ruby/1.8/net/http.rb:380:in get_response' 来自c：/ruby/lib/ruby/1.8/net/http.rb：547：in start' from c:/ruby/lib/ruby/1.8/net/http.rb:379:in get_response' 来自c：/ruby/lib/ruby/1.8/net/http.rb：337：在`get_print'中来自urlparsing1.rb：3

Answer 1

我无法在现代红宝石版本上重现上述行为，但我想我知道是什么导致它。

让我们一步一步地进入执行过程：

▶ u = URI.parse('https://forums.malwarebytes.org/index.php?showtopic=49893')
#⇒ #<URI::HTTPS https://forums.malwarebytes.org/index.php?showtopic=49893>

好的，URI得到了。

▶ Net::HTTP.get_print u
#⇒ <html><head><meta http-equiv='refresh' content='0;
#    url=/index.php?/topic/49893-removal-instructions-for-a-fast-antivirus/'>
#  </head><body></body></html>=> nil

Ooups。重定向。我们来处理它：

▶ u_redir = Net::HTTP.get(u).scan(/url=(.*?)'/).first.first
#⇒ "/index.php?/topic/49893-removal-instructions-for-a-fast-antivirus/"

▶ u.path, u.query = u_redir.split '?'
#⇒ [
#  [0] "/index.php",
#  [1] "/topic/49893-removal-instructions-for-a-fast-antivirus/"
# ]
▶ Net::HTTP.get_print u
#⇒ [HTML CONTENT]

总结：我猜你应该自己处理重定向。

你可以试试这个：

require 'net/http'
require 'uri'

uri = URI.parse('https://forums.malwarebytes.org/index.php?showtopic=49893')


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

res = Net::HTTP.start(uri.host, uri.port,
         :use_ssl => uri.scheme == 'https') {|http| http.request request}
p res.body

`sysread＆＃39;：到达文件结尾（EOFError）
