Question

我一直在用firefox + selenium进行刮擦。但是，我决定改用Phantomjs，因为它应该更快。

我在使用Phantomjs + ghostdriver + selenium和python时添加cookie时遇到问题。为了解决这个问题，我一直在网上寻找解决方案，但我找不到合适的解决方案。

以下是使用的代码。

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.common.exceptions import TimeoutException
from selenium.webdriver.support.ui import WebDriverWait # available since 2.4.0
from selenium.webdriver.support import expected_conditions as EC # available since 2.26.0

driver = webdriver.PhantomJS()
driver.get("http://kswarrants.kasikornsecurities.com/www/Tool/calculator")   
driver.add_cookie({'name':'Disc', 'value':'YES','Domain':'kswarrants.kasikornsecurities.com'})
options = driver.find_elements_by_xpath('//select[@id="underling0"]/option')

收到错误消息：

selenium.common.exceptions.WebDriverException: Message: {"errorMessage":"Can only set Cookies for the current domain","request":{"headers":{"Accept":"applicatio
n/json","Accept-Encoding":"identity","Connection":"close","Content-Length":"110","Content-Type":"application/json;charset=UTF-8","Host":"127.0.0.1","User-
Agent":"Python-urllib/2.7"},"httpVersion":"1.1","method":"POST","post":"{\"sessionId\": \"2eb47d00-fdb0-11e5-af40-4fb0a42a2c0b\", \"cookie\": {\"path\": \"/\",
\"name\": \"Disc\", \"value\": \"YES\"}}","url":"/cookie","urlParsed":{"anchor":"","query":"","file":"cookie","directory":"/","path":"/cookie","relative":"/cook
ie","port":"","host":"","password":"","user":"","userInfo":"","authority":"","protocol":"","source":"/cookie","queryKey":{},"chunks":["cookie"]},"urlOriginal":"
/session/2eb47d00-fdb0-11e5-af40-4fb0a42a2c0b/cookie"}}

主要错误是＆＃34;只能为当前域设置Cookie＆＃34;。但是，在添加cookie之前，我已经导航到了网站。我还注意到请求头中的主机是127.0.0.1，它是本地主机。这可能是问题的根源。有什么方法可以解决这个问题吗？如何更改请求标头中的主机？提前谢谢。

Answer 1

在步骤中添加Cookie：

driver.add_cookie({'name':'Disc', 'value':'YES','Domain':'kswarrants.kasikornsecurities.com'})

你应该使用密钥＆＃39;域名＆＃39;小写＆＃39; d＆＃39;而不是＆＃39;域＆＃39;

Answer 2

添加Cookie时，需要“域名”。这是我的例子，

包括添加Cookie ，获取Cookie 和删除Cookie ：

require 'selenium-webdriver'
require 'phantomjs'

# webdriver.PhantomJS
# install gems and phantomJs first
Selenium::WebDriver::PhantomJS.path = 'C:\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe'
driver = Selenium::WebDriver.for :phantomjs
driver.get 'http://stackoverflow.com/'
puts driver.title

# additional keys that can be passed in are:
# :path => String, :secure -> Boolean, :expires -> Time, DateTime, or seconds since epoch
driver.manage.all_cookies.each { |cookie|
  puts "#{cookie[:name]} => #{cookie[:value]}, #{cookie[:domain]}"
}

# add cookie !! domain is required !!
driver.manage.add_cookie(:name => 'key', :value => 'value', :domain => '.stackoverflow.com')
# Delete By name
driver.manage.delete_cookie 'key'
# Or delete all of them
driver.manage.delete_all_cookies
driver.quit

使用Selenium Ghostdriver PhantomJS和python添加Cookie
