这里用jd_cookies_file=open(cookies_file,‘r’) 打开，为什么最后不用jd_cookies_file.closed() 关闭掉？

保存cookies信息到driver中

def save_cookies_to_driver():
cookies_file = get_cookies_file()
jd_cookies_file = open(cookies_file, “r”)
jd_cookies_str = jd_cookies_file.readline()
jd_cookies_dict = json.loads(jd_cookies_str)

# 这里必须清除掉旧的cookies
driver.get("https://www.jd.com")
driver.delete_all_cookies()
for cookie in jd_cookies_dict:
    driver.add_cookie(cookie)
return driver
