小编Gun*_*ser的帖子

填写表格后,我使用watir和firefox一起抓取一个网页.这是我的代码的一小部分:

browser.button(:type => 'submit').click
sleep 10
browser.element(:id => 'footer').wait_until_present(timeout=30)
html = browser.html

出现此消息:

Instead of passing arguments into #wait_until_present method, use Keywords

那是什么意思？我怎么解决这个问题？感谢帮助.

我发现了很多在 watir firefox 浏览器中实现自定义配置文件设置的提示，但都不起作用。

隐私浏览设置：

profile = Selenium::WebDriver::Firefox::Profile.new
profile['browser.privatebrowsing.dont_prompt_on_enter'] = true
profile['browser.privatebrowsing.autostart'] = true
browser = Watir::Browser.new :firefox, :profile => profile

自动保存文件设置：

profile = Selenium::WebDriver::Firefox::Profile.new
profile['browser.download.folderList'] = 2
profile['browser.download.dir'] = path
profile['browser.helperApps.neverAsk.saveToDisk'] = "text/csv"
browser = Watir::Browser.new :firefox, :profile => profile

错误信息：

/var/lib/gems/2.3.0/gems/selenium-webdriver-3.0.1/lib/selenium/webdriver/remote/w3c_bridge.rb:80:in `initialize': unknown option: {:profile=>#<Selenium::WebDriver::Firefox::Profile:0x000000016da348 @model=nil, @native_events=false, @secure_ssl=false, @untrusted_issuer=true, @load_no_focus_lib=false, @additional_prefs={"browser.privatebrowsing.dont_prompt_on_enter"=>true, "browser.privatebrowsing.autostart"=>true}, @extensions={}>} (ArgumentError)

Firefox 上可以自定义设置吗？怎么了？

• 瓦提尔版本：6.0.2
• 硒版本：3.0.1
• 浏览器版本：火狐51.0.1
• 浏览器驱动版本：geckodriver 0.11.1
• 操作系统版本：Ubuntu 16.04.3 LTS

我只是使用 watir 脚本从服务器下载顺序状态信息。在大多数情况下，它工作正常，但有时我会收到 Net::ReadTimeout 错误。我不知道为什么？

代码：

require "rubygems"\nrequire "watir"\nWatir.default_timeout = 180     # seconds \xe2\x80\x93 default is 60\nprefs = { :download => { :prompt_for_download => false, :default_directory => path } }\nbrowser = Watir::Browser.new :chrome, :switches => %w[--no-sandbox], :prefs => prefs\nbrowser.goto \'https://www...\'\n...\n
