selenium UI自动化给浏览器添加cookies

from selenium import webdriver
import time

driver = webdriver.Firefox()
driver.get(url)
driver.delete_all_cookies()  #删除所有cookies

driver.add_cookie({'name':'JSESSIONID','value':'C37536D4DEC82AF5D7D3A27EA58A0397'})  #添加cookies

driver.get(url)

保存cookies，读取cookies

#保存cookies到文件
import requests, pickle
session = requests.session()
# Make some calls
with open('somefile', 'wb') as f:
    pickle.dump(session.cookies, f)

#从文件读取cookies
session = requests.session()  # or an existing session

with open('somefile', 'rb') as f:
    session.cookies.update(pickle.load(f))

-----------------------------------------------------------
def save_cookie():
    with open('../cookies','w') as f:
        pickle.dump(utils.dict_from_cookiejar(r.cookies), f)

#将RequestsCookieJar类对象转换成了dict格式，然后写入文件。

def get_cookie():
    with open('../cookies','rb') as f:
        cookies = utils.cookiejar_from_dict(pickle.load(f))

#先是用load读出了内容，然后将dict内容转换成RequestsCookieJar类对象格式，除此之外，还把RequestsCookieJar类对象，赋给了cookies这个变量
