Watir - Cookies

在本章中，我们将学习如何使用 Watir 处理 cookie。

这里讨论了一个获取给定 URL 的 cookie 的简单示例。

获取 cookie 的语法

browser.cookies.to_a

示例

require 'watir'

b = Watir::Browser.new :chrome
b.goto 'https://www.tutorialspoint.com'
puts b.cookies.to_a

输出

{:name=>"_gat_gtag_UA_232293_6", :value=>"1", :path=>"/", 
:domain=>".tutorialspoint.com", :expires=>2019-05-03 08:33:58 +0000, 
:secure=>false}

{:name=>"_gid", :value=> "GA1.2.282573155.1556872379", :path=>"/", 
:domain=>".tutorialspoint.com", :expires=>2019-05-04 08:32:57 +0000, 
:secure=>false}

{:name=>"_ga", :value=>"GA1.2.2087825339.1556872379", :path=>"/", 
:domain=>".tutorialspoint.com", :expires=>
2021-05-02 08:32:57 +0000, :secure=>false}

现在让我们添加 cookies，如下所示 −

添加 cookies 的语法

browser.cookies.add 'cookiename', 'cookievalue', path: '/', expires:
(Time.now + 10000), secure: true

示例

require 'watir'
b = Watir::Browser.new :chrome
b.goto 'https://www.tutorialspoint.com'
puts b.cookies.to_a
b.cookies.add 'cookie1', 'testing_cookie', path: '/', expires:
(Time.now + 10000), secure: true
puts b.cookies.to_a

输出之前添加 Cookie

{:name=>"_gat_gtag_UA_232293_6", :value=>"1", :path=>"/", 
:domain=>".tutorialspoint.com", :expires=>2019-05-03 08:44:23 +0000, 
:secure=>false}

{:name=>"_gid", :value=>"GA1.2.1541488984.1556873004", 
:path=>"/", :domain=>".tutorialspoint.com", 
:expires=>2019-05-04 08:43:24 +0000, :secure=>false}

{:name=>"_ga", :value=>"GA1.2.1236163943.1556873004", 
:path=>"/", :domain=>".tutorialspoint.com", 
:expires=>2021-05-02 08:43:24 +0000, :secure=>false}

添加 cookie 后的输出

{:name=>"_gat_gtag_UA_232293_6", :value=>"1", :path=>"/", 
:domain=>".tutorialspoint.com", :expires=>2019-05-03 08:44:23 +0000, 
:secure=>false}

{:name=>"_gid", :value=>"GA1.2.1541488984.1556873004", 
:path=>"/", :domain=>".tutorialspoint.com", 
:expires=>2019-05-04 08:43:24 +0000, :secure=>false}

{:name=>"_ga", :value=>"GA1.2.1236163943.1556873004", 
:path=>"/", :domain=>".tutorialspoint.com", 
:expires=>2021-05-02 08:43:24 +0000, :secure=>false}

{:name=>"cookie1", :value=>"testing_cookie", :path=>"/", 
:domain=>"www.tutorialspoint.com", :expires=>2039-04-28 08:43:35 +0000, 
:secure=>true}

请注意，最后一个是我们使用 watir 添加的。

清除 Cookies

语法

browser.cookies.clear

示例

require 'watir'

b = Watir::Browser.new :chrome
b.goto 'https://www.tutorialspoint.com'
puts b.cookies.to_a
b.cookies.clear
puts b.cookies.to_a

输出

{:name=>"_gat_gtag_UA_232293_6", :value=>"1", :path=>"/", 
:domain=>".tutorialspoint.com", :expires=>2019-05-03 08:48:29 +0000, 
:secure=>false}

{:name=>"_gid", :value=>"GA1.2.1264249563.1556873251", 
:path=>"/", :domain=>".tutorialspoint.com", 
:expires=>2019-05-04 08:47:30 +0000, :secure=>false}

{:name=>"_ga", :value=>"GA1.2.1001488637.1556873251", 
:path=>"/", :domain=>".tutorialspoint.com", 
:expires=>2021-05-02 08:47:30 +0000, :secure=>false

Empty response ie a blank line will get printed after cookie.clear is called.

删除特定的 cookie

语法

browser.cookies.delete 'nameofthecookie'

示例

require 'watir'
b = Watir::Browser.new :chrome
b.goto 'https://www.tutorialspoint.com'
puts b.cookies.to_a
puts b.cookies.delete "_ga"
puts b.cookies.to_a

输出

All cookies:
{:name=>"_gat_gtag_UA_232293_6", :value=>"1", :path=>"/", 
:domain=>".tutorialspoint.com", :expires=>2019-05-03 08:52:38 +0000, 
:secure=>false}

{:name=>"_gid", :value=>"GA1.2.1385195240.1556873499", 
:path=>"/", :domain=>".tutorialspoint.com", 
:expires=>2019-05-04 08:51:37 +0000, :secure=>false}

{:name=>"_ga", :value=>"GA1.2.1383421835.1556873499", 
:path=>"/", :domain=>".tutorialspoint.com", 
:expires=>2021-05-02 08:51:37 +0000, :secure=>false}

After delete cookie with name _ga
{:name=>"_gat_gtag_UA_232293_6", 
:value=>"1", :path=>"/", :domain=>".tutorialspoint.com", 
:expires=>2019-05-03 08:52:38 +0000, :secure=>false}

{:name=>"_gid", :value=>"GA1.2.1385195240.1556873499", 
:path=>"/", :domain=>".tutorialspoint.com", 
:expires=>2019-05-04 08:51:37 +0000, :secure=>false}
