python - BrowserStack 脚本因 MaxRetryError 而失败

Question

来自 https://www.browserstack.com/automate/python 的脚本

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

desired_cap = {
    'browser': 'Chrome',
    'browser_version': '62.0',
    'os': 'Windows',
    'os_version': '10',
    'resolution': '1024x768',
    'name': 'Bstack-[Python] Sample Test'
}

driver = webdriver.Remote(
    command_executor='http://servinc1:key@hub.browserstack.com:80/wd/hub',
    desired_capabilities=desired_cap)

driver.get("http://www.google.com")
if not "Google" in driver.title:
    raise Exception("Unable to load google page!")
elem = driver.find_element_by_name("q")
elem.send_keys("BrowserStack")
elem.submit()
print driver.title
driver.quit()

失败了

urllib3.exceptions.MaxRetryError: HTTPConnectionPool(host='hub.browserstack.com', port=80): Max retries exceeded with url: /wd/hub/session (Caused by NewConnectionError(': Failed to establish a new connection: [Errno 111] Connection refused',))

在具有本地主机 HTTP 代理的系统上。代理配置有 {http,https}_proxy 环境变量:使用请求有效:

import requests
r = requests.get('https://api.github.com/events')

并允许连接到 hub.browserstack.com 也有效。

目的是将 BrowserStack 与本地代理一起使用。这是如何解决的？

Answer 1

所以现在解决方法似乎就是答案:允许所有到 hub.browserstack.com 的连接通过防火墙。例如

iptables -I OUTPUT 1 -p tcp --dport 443 -d hub.browserstack.com  -j ACCEPT
