我正在使用 ruby 版本1.9.3，我喜欢从下面的视频网址中获取主机名，
I tried with code
我试过代码

url = "https://ferrari-view.4me.it/view-share/playerp/?plContext=http://ferrari-%201363948628-stream.4mecloud.it/live/ferrari/ngrp:livegenita/manifest.f4m&cartellaConfig=http://ferrari-4me.weebo.it/static/player/config/&cartellaLingua=http://ferrari-4me.weebo.it/static/player/config/&poster=http://pusher.newvision.it:8080/resources/img1.jpg&urlSkin=http://ferrari-4me.weebo.it/static/player/swf/skin.swf?a=1363014732171&method=GET&target_url=http://ferrari-4me.weebo.it/static/player/swf/player.swf&userLanguage=IT&styleTextColor=#000000&autoPlay=true&bufferTime=2&isLive=true&highlightColor=#eb2323&gaTrackerList=UA-23603234-4"
puts URI.parse(url).host
it throws an exception URI::InvalidURIError: bad URI(is not URI?):
它抛出一个异常 URI::InvalidURIError: bad URI(is not URI?):
I tried with encode the URL then parse like below
我尝试对 URL 进行编码，然后像下面这样解析
puts URI.parse(URI.parse(url)).host
it throws an exception same URI::InvalidURIError: bad URI(is not URI?)
它抛出一个相同的异常 URI::InvalidURIError: bad URI(is not URI?)
But above code works for the below URL.
但上面的代码适用于下面的 URL。
url = http://www.youtube.com/v/GpQDa3PUAbU?version=3&autohide=1&autoplay=1
网址 = http://www.youtube.com/v/GpQDa3PUAbU?version=3&autohide=1&autoplay=1

This url is not valid, but it works in browser because browser itself is less strict about special characters like :, /, etc.
这个 url 无效，但它在浏览器中有效，因为浏览器本身对特殊字符（如 :、/ 等）不太严格。
You should encode your URI first
您应该先对您的 URI 进行编码
encoded_url = URI.encode(url)
And then parse it
然后解析它
URI.parse(encoded_url)

Addressable::URI is a better, more rfc-compliant replacement for URI:
Addressable::URI 是 URI 的更好、更符合 rfc 的替代品：
require "addressable/uri"
Addressable::URI.parse(url).host
#=> "ferrari-view.4me.it"
gem install addressablefirst.
gem install addressable第一的。

try this:
尝试这个：
safeurl = URI.encode(url.strip)
response = RestClient.get(safeurl)
回答by rusllonrails
uri = URI.parse(URI.encode(url.strip))
回答by toch
Your URI query is not valid. There are several charactersthat you should encode with URI::encode(). For instance, #, , or &are not valid in a query.
您的 URI 查询无效。有几个字符应该用URI::encode(). 例如，#、、 或&在查询中无效。
Below a working version of your code
在您的代码的工作版本下方
require 'uri'
plContext = URI::encode("http://ferrari-%201363948628-stream.4mecloud.it/live/ferrari/ngrp:livegenita/manifest.f4m")
cartellaConfig = URI::encode("http://ferrari-4me.weebo.it/static/player/config/")
cartellaLingua = URI::encode("http://ferrari-4me.weebo.it/static/player/config/")
poster = URI::encode("http://pusher.newvision.it:8080/resources/img1.jpg")
urlSkin = URI::encode("http://ferrari-4me.weebo.it/static/player/swf/skin.swf?a=1363014732171")
target_url = URI::encode("http://ferrari-4me.weebo.it/static/player/swf/player.swf")
url = "https://ferrari-view.4me.it/view-share/playerp/?"
url << "plContext=#{plContext}"
url << "&cartellaConfig=#{cartellaConfig}"

url << "&autoPlay=true&bufferTime=2&isLive=true&gaTrackerList=UA-23603234-4"
url << "&highlightColor=#{URI::encode("#eb2323")}"
puts url
puts URI.parse(url).host

URI.parseis right: that URI is illegal. Just because it accidentally happens to work in your browser doesn't make it legal. You cannot parse that URI, because it isn'ta URI.
URI.parse是对的：那个 URI 是非法的。仅仅因为它意外地在您的浏览器中工作并不能使其合法。您无法解析该 URI，因为它不是URI。
