1.cookies

Cookie是储存在用户本地终端上的数据

帮助 Web 站点保存有关访问者的信息，方便用户的访问。如记住用户名密码实现自动登录

from selenium import webdriver
import time
#未登录获取cookie
driver=webdriver.Firefox()
print(driver.get_cookies())    #启动浏览器获取cookies为空
driver.get("https://www.taobao.com/")  #打开主页后获取cookies
print(driver.get_cookies())     #打印出未登陆的cookie

#登陆后获取cookie
driver.find_element_by_link_text("登录").click()
all_h=driver.window_handles
print(driver.title)
driver.switch_to_window(all_h[1])    #获取list里面第二个直接切换
print(driver.title)
time.sleep(3)
driver.find_element_by_xpath(".//*[@id='J_QRCodeLogin']/div[5]/a[1]").click()
time.sleep(3)
driver.find_element_by_id("TPL_username_1").clear()
driver.find_element_by_id("TPL_username_1").send_keys(u"帐户名")
driver.find_element_by_xpath(".//*[@id='TPL_password_1']").send_keys("密码")
time.sleep(3)
driver.find_element_by_id("J_SubmitStatic").click()

time.sleep(3)
print(driver.get_cookies())

driver.delete_cookie(name=" ")    #清除指定cookie
print(driver.get_cookies())
driver.refresh()

#driver.delete_all_cookies()   #清除所有cookie后，cookies为空
