ip代理 源码

一、IP代理概述

IP代理是一种网络服务，通过在客户端和目标服务器之间构建代理服务器，实现数据传输的转发。IP代理首要分为透明代理、反向代理和直连代理三种类型。

二、HTTP代理原理

HTTP代理是IP代理的一种，首要用于处理HTTP协议的请求和响应。当客户端请求一个网页时，HTTP代理服务器会先接收这个请求，然后向目标服务器发送请求，并将目标服务器的响应返回给客户端。

三、IP代理源码分析

以下是一个易懂的IP代理源码示例，使用Python编写

python

import socket

class ProxyServer:

def __init__(self, host, port):

self.host = host

self.port = port

self.server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

self.server_socket.bind((self.host, self.port))

self.server_socket.listen(5)

def handle_client(self, client_socket):

while True:

data = client_socket.recv(1024)

if not data:

break

client_socket.sendall(data)

def run(self):

print("Proxy server is running...")

while True:

client_socket, addr = self.server_socket.accept()

print("Connected by", addr)

handle_client_thread = threading.Thread(target=self.handle_client, args=(client_socket,))

handle_client_thread.start()

if __name__ == "__main__":

proxy_server = ProxyServer('localhost', 8080)

proxy_server.run()

四、HTTP代理源码分析

以下是一个易懂的HTTP代理源码示例，使用Python编写

python

import socket

class HTTPProxyServer:

def __init__(self, host, port):

self.host = host

self.port = port

self.server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

self.server_socket.bind((self.host, self.port))

self.server_socket.listen(5)

def handle_client(self, client_socket):

while True:

data = client_socket.recv(1024)

if not data:

break

request_line = data.split('\n')[0]

request_method, url, _ = request_line.split()

if request_method == 'GET':

target_host, target_port = url.split(':')

target_port = int(target_port) if ':' in url else 80

target_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

target_socket.connect((target_host, target_port))

target_socket.sendall(data)

while True:

target_data = target_socket.recv(1024)

if not target_data:

break

client_socket.sendall(target_data)

target_socket.close()

client_socket.close()

def run(self):

print("HTTP proxy server is running...")

while True:

client_socket, addr = self.server_socket.accept()

print("Connected by", addr)

handle_client_thread = threading.Thread(target=self.handle_client, args=(client_socket,))

handle_client_thread.start()

if __name__ == "__main__":

http_proxy_server = HTTPProxyServer('localhost', 8080)

http_proxy_server.run()
