我的目标是在 Selenium webdriver 中应用代理网关（例如 geosurf.io）。
- 我需要通过使用DesiredCapabilities来做到这一点，因为似乎DesiredCapabilities是插入代理 [gateway] ( source ) 的唯一方法。
- DesiredCapabilities功能在 Selenium Grid 中工作（不仅仅是在普通的 Selenium 服务器中）。硒网格文档。
我已经在本地 Windows 10 机器上成功运行了 Selenium Grid。
因此，我编写了以下代码来为 Selenium webdriver 中使用的功能应用DesiredCapabilities和代理网关：
import requests from selenium import webdriver from selenium.webdriver.common.desired_capabilities import DesiredCapabilities PROXY = "gw1.geosurf.io:8080" # my account at geosurf.io, port 8080 - Germany from selenium.webdriver.common.proxy import Proxy, ProxyType proxy_object = Proxy() proxy_object.proxy_type = ProxyType.MANUAL proxy_object.http_proxy = PROXY proxy_object.socks_proxy = PROXY proxy_object.ssl_proxy = PROXY keep_alive = True browser_profile=None webdriver.DesiredCapabilities.FIREFOX = { "class":"org.openqa.selenium.Proxy", "autodetect":False, "platform": "WIN10" } driver = webdriver.Remote("http://192.168.43.98:5566/grid/register", webdriver.DesiredCapabilities.FIREFOX, browser_profile, proxy_object, keep_alive)
在运行上述代码时，我已经强制输出 webdriver.py （C:\Python27\Lib\site-packages\selenium\webdriver\remote\webdriver.py__init__ ）内部的一些内容，在：
command_executor: http://192.168.43.98:5566/grid/register
capabilities:
{'autodetect': False,
'class': 'org.openqa.selenium.Proxy',
'platform': 'WIN10',
'proxy': {'httpProxy': 'gw1.geosurf.io:8080',
'proxyType': 'MANUAL',
'socksProxy': 'gw1.geosurf.io:8080',
'sslProxy': 'gw1.geosurf.io:8080'}}
然而问题变成了webdriver.py：
Traceback (most recent call last):
File "C:\Users\User\Documents\RnD\captcha-test\test_geosurf_proxy_gateway.py", line 21, in <module>
driver = webdriver.Remote("http://192.168.43.98:5566/grid/register", webdriver.DesiredCapabilities.FIREFOX, browser_profile, proxy_object, keep_alive)
File "C:\Python27\Lib\site-packages\selenium\webdriver\remote\webdriver.py", line 99, in __init__
self.start_session(desired_capabilities, browser_profile)
File "C:\Python27\Lib\site-packages\selenium\webdriver\remote\webdriver.py", line 191, in start_session
self.session_id = response['sessionId']
TypeError: string indices must be integers
错误TypeError: string indices must be integers似乎与proxy gateway类型无关，也DesiredCapabilities与设置无关。
在第 190 行输出时，response变量是一个字符串，包含 html 片段：

如何解决这个webdriver.py问题？

当进一步调试时webdriver.py，我在之后输出response变量response = self.execute(Command.NEW_SESSION, parameters)：

为什么它不包含sessionIdkey-value ？

我的部分成功是跑步
`driver = webdriver.Remote("http://192.168.43.98:5566/wd/hub", webdriver.DesiredCapabilities.FIREFOX, browser_profile, proxy_object, keep_alive)`
作为脚本的最后一行。它产生了以下错误：

将代理地址更改为localhost:8080带来了同样的错误......

我已成功在浏览器http://192.168.43.98:5566/wd/hub/static/resource/hub.html上手动启动/打开节点控制台
然而，我唯一可以加载的会话是 Chrome 浏览器
无法成功为此网格加载 FireFox 或 IE 10 浏览器会话：
我不知道如何管理外部代理插入的网格节点是否有帮助。
