添加使用Firefox Webdriver的Cookie，但不能在PhantomJS中使用 [英] Adding Cookies working with Firefox webdriver but not in PhantomJS

问题描述

我有一个泡菜，里面有我通过以下命令创建的cookie

I have a pickle with cookies that I create through the following command

def doLogin(driver):
    #do login stuff
    pickle.dump(driver.get_cookies(), open("cookies.pkl", "wb"))

我有获取Cookie的示例代码

I have the sample code to get the cookies

driver = webdriver.PhantomJS()
self.doLogin(driver)
driver.delete_all_cookies()
for cookie in pickle.load(open("cookies.pkl", "rb")):
    driver.add_cookie(cookie)

我可以看到它很好地创建了cookie，因为如果我print很好，则add_cookie()正在做可疑的事情

I can see that it creates the cookie well because if I print it it's fine the add_cookie() is doing shady things

这给出了以下例外情况

WebDriverException:消息:{"errorMessage":无法设置 Cookie"，"request":{"headers":{"Accept":"application/json"，"Accept-Encoding":"identity"，"Connection":"close"，"Content-Length":"219" ，"Content-Type":"application/json; charset = UTF-8"，主机":"127.0.0.1:50738"，"User-Agent":"Python-urllib/2.7"}，"httpVersion": "1.1"，方法":"POST"，"post":"{\" sessionId \: \"391db430-154a-11e6-8a0a-ef59204729f5 \"，\"cookie \":{\"domain \": \"secretWebsite \"，\名称\":\"JSESSIONID \"，\值\": \"8332B6099FA3BBBC82893D4C7E6E918B \"，\路径\":\也是一个秘密\"， \"httponly \":否，\"secure \": true}}，" url:"/cookie，" urlParsed:{" anchor:"，" query:"，" file:" cookie，" directory:"/，" path:"/cookie，" relative:"/cookie，" port:"，" host:"，" password:"，" user:"，" userInfo:" ，" authority:"，"协议:"，"源:"/cookie，" queryKey:{}，"块:[" cookie]}，" urlOriginal:"/session /391db430-154a-11e6-8a0a-ef59204729f5/cookie}} 屏幕截图:可通过屏幕查看

要工作，我所需要做的就是将Webdriver更改为Firefox

To work, all I need is to change webdriver to Firefox

这是一个已知的PhantomJS问题吗?

Is this a known PhantomJS issue?

推荐答案

PhantomJS驱动程序似乎不支持某些键/值. 为了克服这个问题，我将使用execute_script注入最重要的变量:

It seems that some key/values are not supported by the PhantomJS driver. To overcome this issue, I would inject the most important ones with execute_script:

def save_cookies(driver, file_path):
    LINE = "document.cookie = '{name}={value}; path={path}; domain={domain}; expires={expires}';\n"
    with open(file_path, 'w') as file :
        for cookie in driver.get_cookies() :
            file.write(LINE.format(**cookie))

def load_cookies(driver, file_path):
    with open(file_path, 'r') as file:
        driver.execute_script(file.read())


from selenium import webdriver

driver = webdriver.PhantomJS()

# load the domain
driver.get("https://stackoverflow.com/users/login")

# save the cookies to a file
save_cookies(driver, r"cookies.js")

# delete all the cookies
driver.delete_all_cookies()

# load the cookies from the file
load_cookies(driver, r"cookies.js")
