`sysread'：到达文件结尾（EOFError）

2018-05-31 07:29:55

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

我得到一个错误，如下所示:: 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'from c：/ruby/lib/ruby/1.8/timeout.rb：56：in timeout' from c:/ruby/lib/ruby/1.8/timeout.rb:76:in超时时间从c：/ruby/lib/ruby/1.8/net/protocol.rb：132：在rbuf_fill' from c:/ruby/lib/ruby/1.8/net/protocol.rb:116:in readuntil'从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'from 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 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'from c：/ruby/lib/ruby/1.8/ net / http.rb：547： start' from c:/ruby/lib/ruby/1.8/net/http.rb:379:in get_response中从c：/ruby/lib/ruby/1.8/net/http开始。 rb：337：来自urlparsing1.rb：3的`get_print'中

我不能在现代ruby版本上重现上述行为，但我想我知道是什么原因造成的。

让我们一步一步潜入执行过程：

▶ 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。让我们来处理它：

▶ 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：我想你应该自己处理重定向。

你可以尝试使用这个：

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
