直接从我的另一个答案复制而来。
好吧,实际上你可以,我已经用几行代码完成了这个,而且效果很好。
import requests
class Client:
def __init__(self):
self._session = requests.Session()
self.proxies = None
def set_proxy_pool(self, proxies, auth=None, https=True):
"""Randomly choose a proxy for every GET/POST request
:param proxies: list of proxies, like ["ip1:port1", "ip2:port2"]
:param auth: if proxy needs auth
:param https: default is True, pass False if you don't need https proxy
"""
from random import choice
if https:
self.proxies = [{'http': p, 'https': p} for p in proxies]
else:
self.proxies = [{'http': p} for p in proxies]
def get_with_random_proxy(url, **kwargs):
proxy = choice(self.proxies)
kwargs['proxies'] = proxy
if auth:
kwargs['auth'] = auth
return self._session.original_get(url, **kwargs)
def post_with_random_proxy(url, *args, **kwargs):
proxy = choice(self.proxies)
kwargs['proxies'] = proxy
if auth:
kwargs['auth'] = auth
return self._session.original_post(url, *args, **kwargs)
self._session.original_get = self._session.get
self._session.get = get_with_random_proxy
self._session.original_post = self._session.post
self._session.post = post_with_random_proxy
def remove_proxy_pool(self):
self.proxies = None
self._session.get = self._session.original_get
self._session.post = self._session.original_post
del self._session.original_get
del self._session.original_post
# You can define whatever operations using self._session
我这样使用它:
client = Client()
client.set_proxy_pool(['112.25.41.136', '180.97.29.57'])
这很简单,但实际上对我有用。
