自动下载文件在watir [英] Auto Download files in watir

问题描述

如何在浏览器中自动下载excel文件，只需点击链接即可，而无需通过save as等窗口中的其他窗口。我正在努力保持操作系统的独立性，所以不会对使用win32ole gem感兴趣。

How to auto download the excel files from the browser in one click on the link, without going through the "save as" and other windows in watir. I am trying to keep it OS independent, so would not be interested in using win32ole gem.

推荐答案

个人资料偏好设置

我的代码如下所示：

：

profile = Selenium::WebDriver::Chrome::Profile.new
profile['download.default_directory'] = download_directory
profile['download.prompt_for_download'] = false
browser = Watir::Browser.new :chrome, :profile => profile

chrome驱动程序2： p>

chrome driver 2:

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

caps = Selenium::WebDriver::Remote::Capabilities.chrome
caps['chromeOptions'] = {'prefs' => prefs}
browser = Watir::Browser.new :chrome, :desired_capabilities => caps

firefox：

profile = Selenium::WebDriver::Firefox::Profile.new
profile['browser.download.lastDir'] = download_directory
profile['browser.download.folderList'] = 2
profile['browser.download.dir'] = download_directory
profile['browser.download.manager.showWhenStarting'] = false
profile['browser.helperApps.alwaysAsk.force'] = false
profile['browser.helperApps.neverAsk.openFile'] = "text/csv,application/pdf"
profile['browser.helperApps.neverAsk.saveToDisk'] = "text/csv,application/pdf"
profile['pdfjs.disabled'] = true
browser = Watir::Browser.new :firefox, :profile => profile

（仅适用于pdf文件的firefox示例） p>

(firefox example for me working only for pdf files)

但硒浏览器下载有许多错误

chrome或firefox webdriver中的某些问题（像这样 http://code.google.com/p/chromedriver/issues/detail?id=130 ）
不允许为文件下载写好测试

some problem in chrome or firefox webdriver (like this http://code.google.com/p/chromedriver/issues/detail?id=130) do not allow write good tests for file downloads

我为下载文件写了以下ruby脚本

I wrote the following ruby script for download files

require ‘rubygems’
require "net/http"
require "uri"

def download(_url, _download_path = ")
    url = URI.parse _url
    http_object = Net::HTTP.new(url.host, url.port)
    http_object.use_ssl = true if (url.scheme == ‘https’ || url.port == 443)

    http_object.start.request_get(url.path) do |response|
        start_time = Time.now
        response["Content-Disposition"] =~ /^.+?filename="(.+?)"$/
        file_name = $1
        file = open(_download_path + file_name, ‘wb’)
        length = response['Content-Length'].to_i
        response.read_body do |fragment|
            file.write(fragment)
        end
        file.close
        file_size = File.size(_download_path + file_name)/1024.0/1024.0
        puts "-"*80
        puts "Download time – #{Time.now – start_time}"
        puts "Download speed – #{file_size/(Time.now – start_time)} MB/s"
        puts "-"*80
    end
end

download(‘http://storagemadeeasy.com/files/1cf064a30aba6d1b8fbc0fba8ac8be5b.jpg’)

我希望这段代码对于那些需要测试文件下载（不是浏览器文件下载对话窗口）的人来说是有用的。

I hope this code will be useful for those who need test file download (not browser file download dialog window)
