将requests.Session（）cookie传递给Python中的selenium web驱动程序

Question

经过研究和修补之后，我似乎被困在了我可以尝试的地方。我基本上想在这里做这个问题的相反：Is it possible to "transfer" a session between selenium.webdriver and requests.session

我想“点击”一个网页上的JavaScript按钮，我通过一系列的GET/POST请求会话（由于我的GET/POST请求位于需要登录用户的页面上，Cookie保持并无缝传输非常重要）。

但是，在一些谷歌搜索后，我发现请求似乎没有提供这样的东西。我发现硒，一直试图正确地转移曲奇（失败）。

import requests, requests.utils, lxml.html 
from lxml.cssselect import CSSSelector 
from selenium import webdriver 

# urls which requests will be made to 
login_url = 'login-url-here' 
logged_in_data_url = 'logged-in-data-here' 

# create my Session to contain my cookies 
with requests.Session() as s: 
    login_html = s.get(login_url) 
    tree = lxml.html.fromstring(login_html.text) 
    important_key1 = list(set(tree.xpath('//*[@id="fm1"]/div/div[3]/input[1]/@value')))[0] 
    important_key2 = list(set(tree.xpath('//*[@id="fm1"]/div/div[3]/input[2]/@value')))[0] 
    form_value = "submit" 

    login_payload = { 
     'post-field-1': 'post-data-1', 
     'post-field-2': 'post-data-2', 
     'important_key1': 'important_value1', 
     'important_key2': 'important_value2', 
     'important_key3': 'important_value3' 
    } 

    login_result = s.post(login_url, 
        data=login_payload, 
        headers = dict(referer=login_url)) 

    logged_in_data_html = s.get(logged_in_data_url) 
    tree = lxml.html.fromstring(logged_in_data_html.text) 
    print(logged_in_data_html.text) 

    # Attempt at transferring cookies, currently fails 
    cookie_dict = requests.utils.dict_from_cookiejar(s.cookies) 
    driver = webdriver.Firefox() 
    for cookie in cookie_dict: 
     driver.add_cookie(cookie) 

    driver.get(logged_in_data_url) 

    # prints same contents as login_html.text, 
    # meaning cookie transfer failed and the session was thrown out 
    print(driver.page_source) 

有什么建议或指示从这里做什么？

编辑：我尝试用selenium-requests：

import seleniumrequests 
import lxml.html 
from lxml.cssselect import CSSSelector 

# urls which requests will be made to 
login_url = 'login-url-here' 
logged_in_data_url = 'logged-in-data-here' 

driver = seleniumrequests.Firefox() 

login_html = driver.request('GET', login_url) 
tree = lxml.html.fromstring(login_html.text) 
important_key1 = list(set(tree.xpath('//*[@id="fm1"]/div/div[3]/input[1]/@value')))[0] 
important_key2 = list(set(tree.xpath('//*[@id="fm1"]/div/div[3]/input[2]/@value')))[0] 
form_value = "submit" 

# following print statements print value1, value2 respec 
print ("important_key1 = " + important_key1) 
print("important_key2 = " + important_key2) 

login_payload = { 
    'post-field-1': 'post-data-1', 
    'post-field-2': 'post-data-2', 
    'important_key1': 'important_value1', 
    'important_key2': 'important_value2', 
    'important_key3': 'important_value3' 
} 

login_result = driver.request('POST', login_url, 
           data=login_payload, 
           headers = dict(referer=login_url)) 

# this should print out the landing page after being logged in 
# source code contains important_key1, 2, and 3 with different values 
# the GET and POST requests seem to be in different sessions 
# how do I fix that? 
print(login_result.text)

我不相信这是可以做到的原生地。然而，Selenium的扩展名为selenium-requests，您应该可以使用它。

编辑：

尝试添加以下内容到您的代码。在阅读的来源，这应该工作（并使用requestsSession自动初始化POST请求期间。

response = driver.request('GET', logged_in_data_url)
