selenium + firefox + webdriver 遇到的坑

lunix中启动webdriver时报错一：

测试代码为：

1. #!/usr/bin/python
2. # -*- coding: utf-8 -*-
5. from selenium import webdriver
7. driver = webdriver.Firefox()
8. driver.get("https://www.baidu.com")

运行报错信息如下：

1. Traceback (most recent call last):
2. File "maimai_web.py", line 14, in <module>
3. driver = webdriver.Firefox()
4. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/firefox/webdriver.py", line 152, in __init__
5. keep_alive=True)
6. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 98, in __init__
7. self.start_session(desired_capabilities, browser_profile)
8. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 188, in start_session
9. response = self.execute(Command.NEW_SESSION, parameters)
10. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 256, in execute
11. self.error_handler.check_response(response)
12. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/errorhandler.py", line 194, in check_response
13. raise exception_class(message, screen, stacktrace)
14. selenium.common.exceptions.WebDriverException: Message: Process unexpectedly closed with status 1

处理方法：

1. #!/usr/bin/python
2. # -*- coding: utf-8 -*-
5. from pyvirtualdisplay import Display
6. from selenium import webdriver
9. display = Display(visible=0, size=(1920, 1080))
10. display.start()
11. driver = webdriver.Firefox()
12. driver.get("https://www.baidu.com")

结果：

运行ok，搞定！

坑二、webdriver实例化报错

采用多线程调用webdriver时候，偶尔会出现这样的错：selenium.common.exceptions.WebDriverException: Message: connection refused

1. Exception in thread Thread-2:
2. Traceback (most recent call last):
3. File "/usr/local/python3.6/lib/python3.6/threading.py", line 916, in _bootstrap_inner
4. self.run()
5. File "/usr/local/python3.6/lib/python3.6/threading.py", line 864, in run
6. self._target(*self._args, **self._kwargs)
7. File "maimai_tran_account_driver.py", line 591, in debug
8. t = TrainAccount(count,lock)
9. File "maimai_tran_account_driver.py", line 32, in __init__
10. self.chrome = webdriver.Firefox()
11. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/firefox/webdriver.py", line 152, in __init__
12. keep_alive=True)
13. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 98, in __init__
14. self.start_session(desired_capabilities, browser_profile)
15. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 188, in start_session
16. response = self.execute(Command.NEW_SESSION, parameters)
17. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/webdriver.py", line 256, in execute
18. self.error_handler.check_response(response)
19. File "/usr/local/python3.6/lib/python3.6/site-packages/selenium/webdriver/remote/errorhandler.py", line 194, in check_response
20. raise exception_class(message, screen, stacktrace)
21. selenium.common.exceptions.WebDriverException: Message: connection refused
