[英]Getting selenium.common.exceptions.InvalidSessionIdException: Message: invalid session id
[英]selenium.common.exceptions.InvalidSessionIdException using GeckoDriver Selenium Firefox in headless mode through Python
我正在尝试使用 python 和 selenium 在 firefox 无头模式下自动执行某些情况。 我想,我做了我需要的所有设置,但 webdrvier 仍然没有初始化。
我的问题是在执行我的代码后大约 30-60 秒出现异常,异常消息不清楚,实际上消息部分是空的。 正如您在 geckodriver.log firefox 上看到的那样以无头模式运行。
我使用 Firefox 56.0.1、python 3.6、selenium 3.141.0。 这是我的代码和日志;
代码:
import os
import time
import selenium
from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
from selenium.webdriver.firefox.options import Options
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.firefox.firefox_profile import FirefoxProfile
options = Options()
options.set_headless(True)
dir = "C:\\Python36\\Lib\\site-packages\\selenium\\webdriver\\firefox"
ff_driver_path = dir + "\\geckodriver.exe"
firefox_capabilities = DesiredCapabilities().FIREFOX
firefox_capabilities['marionette'] = True
profile = webdriver.FirefoxProfile()
binary = FirefoxBinary('C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe')
driver = webdriver.Firefox(desired_capabilities=firefox_capabilities, firefox_profile=profile, firefox_binary=binary, firefox_options=options, executable_path=ff_driver_path)
driver.get("https://ipaddress/")

关于我做错了什么的任何想法? 谢谢!
这个错误信息...
selenium.common.exceptions.InvalidSessionIdException: Message:
...暗示GeckoDriver无法启动/生成新的WebBrowsing 会话,即Firefox 浏览器会话。
根据日志消息, geckodriver 版本号不再反映在启动时,因此您必须使用:
GeckoDriver版本 => 0.22.0 (2018-09-15)
但是您正在使用:
因此,您的主要问题是您使用的GeckoDriver 、 Selenium和Firefox二进制文件版本之间的不兼容。
如果您使用GeckoDriver - Selenium - Firefox组合,您需要遵循以下支持平台的兼容性图表:
在 MS Windows 中切换虚拟桌面时也会出现此消息。您问:
我在哪里可以找到有关这些组合的更多信息?
您可以使用自动为您下载驱动程序的工具。
from webdriver_manager.chrome import ChromeDriverManager
from seleniumrequests import Chrome
driver = Chrome(ChromeDriverManager().install())
