ruby - HTTP 请求路径为空 (ArgumentError)

Question

我是 ruby​​ 编程的新手。这是我在 Watir 的第一个程序。当我执行下面的代码时，我得到 HTTP 请求路径为空 (ArgumentError)。感谢您帮助修复此错误。我正在通过代理设置访问互联网。我在环境变量中添加了 HTTP_PROXY 变量到 http://myproxy.mynetwork.net:8008/

测试.rb

require "watir"
require "rubygems"
require "rspec"
require "watir-webdriver"

puts "Hello,World...!" 

@browser = Watir::Browser.new
@browser.goto("http://www.google.com")   
@browser.close
puts "Browser should have been closed.."

输出

d:\>ruby test.rb

Firefox 浏览器窗口正在打开。之后地址栏没有变化，一段时间后它会关闭。

net/http 需要一个有效的路径。所以你必须在 URL 的末尾加上一个斜杠，像这样:

@browser.goto("http://www.google.com/")
