平台支持

这是一个跨平台的python模块，前提是python解释器的版本应该是3.6+。

API 参考

import requests
...
...

class ProxySession(requests.Session):
    def __init__(self, user_=None, pass_=None, socks=False):
        '''
        @param user_: str[None] -> Username for proxy authentication
        @param pass_: str[None] -> Password for proxy authentication
        @param socks: bool[False] -> If True, it will perform a socks5
                authentication, given the user_ and pass_ has been
                provided. If False, it will perform a basic authent-
                ication will be performed, provided the value of
                user_ and pass_.
        '''
        super(ProxySession, self).__init__()
        ...
        ...
    ...
    ...
    def make_request(self, url, method='GET', timeout=ProxySessionTimeout.SHORT_TIMEOUT, log = True, max_attempt = 100, **kwargv):
        '''
        @param url: str -> The target URL
        @param method: str[GET] -> The HTTP method to be called
        @param timeout: int[5] -> The timeout value, for the proxy request
        @param log: bool[True] -> It will log the necessary information
        @param max_attempt: int[100] -> Maximum number of attempt to reach the target URL,
                must be a positve integer
        @param **kwargv -> Other keyword arguments, which will be passed to requests.request
                method

        @return -> It will always return the tuple of two element, response and proxy_url
                On success, it will return the reponse object, returned by the method call and
                the proxy url. If the random proxy selection is made, it will return the proxy
                url as a string, otherwise it will be same as keyword argument "proxies". 
                On Failure after maximum attempts, it will return a Response object, having
                status_code -1 with empty content. The proxy url will be null in this case.
        '''
        ...
        ...
    ...
    ...

从GitHub找到完整的源代码。

如果您需要使用socks代理发出请求，请确保安装PySocks。或者，只需运行以下命令。

pip install requests[socks]

如果您将关键字参数传递proxies给ProxySession.make_request方法（如requests.request(...)），它将阻止任何随机代理选择。

随机代理从Free Proxy List - Just Checked Proxy List中报废。此模块提供了一种可靠的方式来查找免费且实时的代理服务器，但是，它不会评估代理服务器的任何安全性，因此它不能保证您的个人和/或机密数据。使用付费代理总是比免费代理更好。

用法

from sys import stderr
from proxy_session import ProxySession
from proxy_session import ProxySessionTimeout

if __name__ == '__main__':
    with ProxySession() as ps:
        error_ = ps.error
        if error_:
            print('Error Status: ', error_[0], file=stderr)
            print('Error:\n' + error_[1], file=stderr)
        response, proxy_addr = ps.make_request('https://httpbin.org/ip', timeout=ProxySessionTimeout.LONG_TIMEOUT, log=True)
        if response.status_code == 200:
            print(f'Response Content:\n{response.text}')
            print(f'Proxy URL: {proxy_addr}')
        else:
            print(f'{response}')

上面的代码在我测试时生成了以下输出。

Trying random free proxy[https]: http://103.109.58.102:46523
Trying random free proxy[https]: http://157.230.103.189:36366
Trying random free proxy[https]: http://85.15.152.39:3128
Response Content:

}
