Selenium: Trying to log in with cookies and get the errorMessage - “Can only set cookies for current domain” or "Unable to set Cookie"

from selenium import webdriver

driver = webdriver.PhantomJS(executable_path='G:/OpenSources/phantomjs-2.1.1-windows/bin/phantomjs')
driver.get("http://pythonscraping.com")
driver.implicitly_wait(1)
print(driver.get_cookies())

savedCookies = driver.get_cookies()10 
driver2 = webdriver.PhantomJS(executable_path='G:/OpenSources/phantomjs-2.1.1-windows/bin/phantomjs')
driver2.get("http://pythonscraping.com")
driver2.delete_all_cookies()
for cookie in savedCookies:
    driver2.add_cookie(cookie)

driver2.get("http://pythonscraping.com")
driver2.implicitly_wait(1)
print(driver2.get_cookies())

以上代碼15行報錯: "errorMessage":"Can only set Cookies for the current domain"

將15行代碼改為:

driver2.add_cookie({k: cookie[k] for k in ('name', 'value', 'domain', 'path', 'expiry') if k in cookie})

修改后報錯: "errorMessage":"Unable to set Cookie"

最終修改:

from selenium import webdriver
import time

driver = webdriver.PhantomJS(executable_path='G:/OpenSources/phantomjs-2.1.1-windows/bin/phantomjs')
driver.get("http://pythonscraping.com")
driver.implicitly_wait(1)
print(driver.get_cookies())

savedCookies = driver.get_cookies()11 
driver2 = webdriver.PhantomJS(executable_path='G:/OpenSources/phantomjs-2.1.1-windows/bin/phantomjs')
driver2.get("http://pythonscraping.com")
driver2.delete_all_cookies()
for cookie in savedCookies:
    # fix the problem-> "errorMessage":"Unable to set Cookie"
    for k in ('name', 'value', 'domain', 'path', 'expiry'):
        if k not in list(cookie.keys()):
            if k == 'expiry':
                t = time.time()
                cookie[k] = int(t) # 時間戳 秒
    # fix the problem-> "errorMessage":"Can only set Cookies for the current domain"
    driver2.add_cookie({k: cookie[k] for k in ('name', 'value', 'domain', 'path', 'expiry') if k in cookie})

driver2.get("http://pythonscraping.com")
driver2.implicitly_wait(1)
print(driver2.get_cookies())

 在這個例子中，第一個 webdriver獲得了一個網站，打印 cookie 並把它們保存到變量savedCookies里。第二個webdriver加載同一個網站（技術提示：必須首先加載網站，這樣Selenium 才能知道cookie 屬於哪個網站，即使加載網站的行為對我們沒任何用處），刪除所有的cookie ，然后替換成第一個webdriver得到的cookie 。當再次加載這個頁面時，兩組cookie 的時間戳、源代碼和其他信息應該完全一致。
