如何使用Ruby解析没有响应标头的HTML响应 [英] How can I Parse an HTML response without response headers using Ruby

问题描述

在没有响应头的情况下如何获取HTML响应?

How can I grab an HTML response when there are no response headers?

我有这个:

require 'hpricot'
require 'open-uri'

doc = Hpricot(open('http://192.168.100.1/phy.htm'))

在这种情况下，服务器是不返回HTTP响应标头的电缆调制解调器.

The server in this case is a cable modem that is not returning HTTP Response headers.

上面的代码失败并显示:

The above code is failing with:

C:/Ruby/lib/ruby/1.8/net/http.rb:2022:在'read_status_line'中:错误的状态行: (Net :: HTTPBadResponse)

C:/Ruby/lib/ruby/1.8/net/http.rb:2022:in `read_status_line': wrong status line: "" (Net::HTTPBadResponse)

来自C:/Ruby/lib/ruby/1.8/net/http.rb:2009:位于"read_new"中

from C:/Ruby/lib/ruby/1.8/net/http.rb:2009:in `read_new'

来自C:/Ruby/lib/ruby/1.8/net/http.rb:1050:在'request'中

from C:/Ruby/lib/ruby/1.8/net/http.rb:1050:in `request'

从C:/Ruby/lib/ruby/1.8/open-uri.rb:248:在'open_http'中

from C:/Ruby/lib/ruby/1.8/open-uri.rb:248:in `open_http'

推荐答案

因此，如果您的服务器不符合HTTP规范，也许您应该完全放弃HTTP想法并直接与Socket一起使用...

So if your server is not HTTP compliant, maybe you should drop HTTP idea altogether and work with Socket directly...

然后，您可以将hpricot与返回的字符串一起使用.

Then you can use hpricot with a string returned.
