使用Selenium/Python旋转代理
因此,我在GitHub上找到了从中收集IP的代码:并旋转它们。但当我尝试运行它时,会收到一条错误消息 我使用ChromeDriver 2.41是因为我第一次得到了关于Socks整数的不同错误。使用ChromeDriver 2.41解决了这个问题,但我仍然无法通过这个“pxy”引用 此外,pycharm提醒我,“pd”有一个重新声明的定义,没有使用。对于“pxy”和“pd”错误,我非常感谢您的帮助 代码如下:使用Selenium/Python旋转代理,python,selenium,selenium-webdriver,proxy,Python,Selenium,Selenium Webdriver,Proxy,因此,我在GitHub上找到了从中收集IP的代码:并旋转它们。但当我尝试运行它时,会收到一条错误消息 我使用ChromeDriver 2.41是因为我第一次得到了关于Socks整数的不同错误。使用ChromeDriver 2.41解决了这个问题,但我仍然无法通过这个“pxy”引用 此外,pycharm提醒我,“pd”有一个重新声明的定义,没有使用。对于“pxy”和“pd”错误,我非常感谢您的帮助 代码如下: from selenium import webdriver from selenium
from selenium import webdriver
from selenium.webdriver.chrome.options import DesiredCapabilities
from selenium.webdriver.common.proxy import Proxy, ProxyType
import time
co = webdriver.ChromeOptions()
co.add_argument("log-level=3")
co.add_argument("--headless")
def get_proxies(co=co):
driver = webdriver.Chrome(chrome_options=co)
driver.get("https://free-proxy-list.net/")
PROXIES = []
proxies = driver.find_elements_by_css_selector("tr[role='row']")
for p in proxies:
result = p.text.split(" ")
if result[-1] == "yes":
PROXIES.append(result[0]+":"+result[1])
driver.close()
return PROXIES
ALL_PROXIES = get_proxies()

prox = Proxy()
if PROXIES:
pxy = PROXIES[-1]
else:
print("--- Proxies used up (%s)" % len(PROXIES))
PROXIES = get_proxies()
prox.proxy_type = ProxyType.MANUAL
prox.http_proxy = pxy
prox.socks_proxy = pxy
prox.ssl_proxy = pxy
capabilities = webdriver.DesiredCapabilities.CHROME
prox.add_to_capabilities(capabilities)
driver = webdriver.Chrome(chrome_options=co, desired_capabilities=capabilities)
return driver
# --- YOU ONLY NEED TO CARE FROM THIS LINE ---
# creating new driver to use proxy
pd = proxy_driver(ALL_PROXIES)
# code must be in a while loop with a try to keep trying with different proxies
running = True
while running:
try:
mycodehere()
# if statement to terminate loop if code working properly
something()
# you
except:
new = ALL_PROXIES.pop()
# reassign driver if fail to switch proxy
pd = proxy_driver(ALL_PROXIES)
print("--- Switched proxy to: %s" % new)
这是我得到的错误:
Traceback (most recent call last):
File "scripts2.py", line 65, in <module>
pd = proxy_driver(ALL_PROXIES)
File "scripts2.py", line 53, in proxy_driver
prox.http_proxy = pxy
UnboundLocalError: local variable 'pxy' referenced before assignment
回溯(最近一次呼叫最后一次):
文件“scripts2.py”,第65行,在
pd=代理驱动程序(所有代理)
代理驱动程序中的第53行文件“scripts2.py”
prox.http_proxy=pxy
UnboundLocalError:赋值前引用的局部变量“pxy”
我有点困惑,因为我认为“pxy”是在if代理下分配的?试着在下面几行中更改它 当前代码:
if PROXIES:
pxy = PROXIES[-1] # script will fail if this condition not met
else:
print("--- Proxies used up (%s)" % len(PROXIES))
PROXIES = get_proxies()
更新代码:
# make sure to reset pxy to either null or empty
pxy = ''
if (PROXIES is None):
#print("--- Proxies used up (%s)" % len(PROXIES))
PROXIES = get_proxies()
pxy = PROXIES[-1]
# I would check if pxy is empty or not before doing assignment
if (pxy!=''):
#Then do the logic here
无法在运行时更改代理,您必须重新创建驱动程序实例
