如何通过firefox_options将日志级别的geckodriver配置为跟踪？

标签： python selenium firefox selenium-webdriver geckodriver

我尝试在VPS上运行硒以在python中运行测试。我有一些python代码

from selenium import webdriver
from selenium.webdriver.firefox.options import Options

options = Options()
options.log.level = 'trace'
selenium = Firefox(firefox_options=options)

我得到一个错误

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/testy/.local/lib/python2.7/site-packages/selenium/webdriver/firefox/webdriver.py", line 174, in __init__
    keep_alive=True)
  File "/home/testy/.local/lib/python2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 157, in __init__
    self.start_session(capabilities, browser_profile)
  File "/home/testy/.local/lib/python2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 252, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "/home/testy/.local/lib/python2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute
    self.error_handler.check_response(response)
  File "/home/testy/.local/lib/python2.7/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: connection refused

Firefox启动，但是，在python引发异常之后，它才可用，并且它对此无效。

geckodriver.log说

您能告诉我，您知道其他类似情况的调试方法吗？ 我在用 python 2.7

硒3.14.1

firefox 59.0.2（与ff62产生相同的错误）

geckodriver 0.21（0.23会产生相同的错误）

1 个答案:

答案 0 :(得分：1)

根据 Selenium Python Client v3.14.0 的selenium.webdriver.firefox.options的文档，您需要使用：

class selenium.webdriver.firefox.options.Log

示例代码块：

from selenium import webdriver
from selenium.webdriver.firefox.options import Options
from selenium.webdriver.firefox.options import Log

log = Log()
log.level = "TRACE"
options = Options()
options.add_argument(log.level)
browser = webdriver.Firefox(firefox_options=options,executable_path="C:\\path\\to\\geckodriver.exe")
browser.get('http://google.com/')
