使用 Watir Webdriver 下载文件

Question

我想使用 Watir Webdriver 从页面下载文件。我需要能够将下载位置设置为我定义的目录。我找到 this page，但那里的代码不起作用：

profile = Selenium::WebDriver::Chrome::Profile.new
profile['download.prompt_for_download'] = false
profile['download.default_directory'] = download_directory

b = Watir::Browser.new :chrome, :profile => profile

（其中 download_directory 只是我的桌面）给出了这个：

Selenium::WebDriver::Error::UnknownError: unknown error: cannot parse capability: chromeOptions
from unknown error: unrecognized chrome option: profile
  (Driver info: chromedriver=2.19.346063 (38b35413bd4a486d436a9749e090454bc9ff6708),platform=Mac OS X 10.11.0 x86_64)
from /Users/myusername/.rvm/gems/ruby-1.9.3-p551/gems/selenium-webdriver-2.48.1/lib/selenium/webdriver/remote/response.rb:70:in `assert_ok'

我猜该代码适用于旧版本的 Watir。如何通过 Watir 设置 Chrome 的下载位置？

Answer 1

您的示例适用于旧的 chrome（webdriver 1）适用于 new 您必须使用以下代码：

prefs = {
    'download' => {
        'default_directory' => download_directory,
        'prompt_for_download' => false,
    },
    'profile' => {
        'default_content_settings' => {'multiple-automatic-downloads' => 1}, #for chrome version olde ~42
        'default_content_setting_values' => {'automatic_downloads' => 1}, #for chrome newe 46
    }
}

caps = Selenium::WebDriver::Remote::Capabilities.chrome
caps['chromeOptions'] = {:prefs => prefs}

b = Watir::Browser.new :chrome, :desired_capabilities => caps

关于这个问题，你可以参考我以前的 answer

Answer 2

基于，我发现我可以使用这个 shorter/cleaner 版本：

preferences = { 
  :download => {
    :prompt_for_download => false,
    :directory_upgrade => true,
    :default_directory => "download_directory"
  }   
}   

browser = Watir::Browser.new :chrome, :prefs => preferences
