如何實現Mac OS HTTP監視器

Question

我需要編寫應用程序來監視mac os上的所有http請求/響應。如何在Mac OS中註冊代理服務器。

Answer 1

我找到了一個簡單的例子 - 重定向請求/響應的python tcp服務器和自動設置Mac OS代理設置的代碼。

Python腳本從http://www.cppfun.com/python-2-7-simple-http-proxy-server.htm採取的Mac OS從How to set proxy settings on MacOS using python

import socket, sys 
import os 
from thread import * 

max_conn = 8 
buffer_size = 8192 


def proxy_on(port): 
    os.system('networksetup -setwebproxy Ethernet '+'127.0.0.1'+' '+str(port)) 

def proxy_off(): 
    os.system('networksetup -setwebproxystate Ethernet off') 

def app(): 
    try: 
     listen_port = int(raw_input("[*] Enter listening port(a number eg 8098):")) 
     proxy_on(listen_port) 
     start(listen_port) 
    except KeyboardInterrupt: 
     print "\n[*] User requested interrupt\n[*] Program exiting ..." 
     sys.exit() 

def start(listen_port): 
    try: 
     s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
     s.bind(('', listen_port)) 
     s.listen(max_conn) 
     print "[*] Init sockets ... Done" 
     print "[*] Sockets bind success ..." 
     print "[*] Proxy server success [%d]\n" % listen_port 
    except Exception, e: 
     print "\n", e 
     print "[*] Unable to init socket, maybe try another port" 
     sys.exit(2) 

    while True: 
     try: 
      conn, addr = s.accept() 
      data = conn.recv(buffer_size) 
      start_new_thread(conn_str, (conn, data, addr)) 
     except KeyboardInterrupt: 
      s.close() 
      print "\n[*] Proxy server shutdown ..." 
      print "[*] Have a good day !" 
      proxy_off() 
      sys.exit(1) 
    s.close() 

def conn_str(conn, data, addr): 
    try: 
     first_line = str(data).split('\n')[0] 
     url = first_line.split(' ')[1] 
     print url 
     host, port = get_host_and_port(url) 
     print host, port, data 
     proxy_server(host, port, conn, addr, data) 
    except Exception, e: 
     print "\n", e 
     print "[*] Get the http url or port fail ..." 
     sys.exit(1) 

def get_host_and_port(url): 
    import urllib 
    _, rest = urllib.splittype(url) 
    host, rest = urllib.splithost(rest) 
    host, port = urllib.splitport(host) 
    if port is None: 
     port = 80 

    return host,port 

def proxy_server(host, port, conn, addr, data): 
    try: 
     s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
     s.connect((host, port)) 
     s.send(data) 

     while True: 
      reply = s.recv(buffer_size) 
      if len(reply) > 0: 
       conn.send(reply) 
       dat = float(len(reply))/1024.0 
       dat = "%.3s KB" % str(dat) 
       print "[*] Request done : %s => %s <=" % (addr[0], dat) 
      else: 
       break 
     s.close() 
     conn.close() 
    except socket.error, (value, message): 
     print "\n[*] Socket error %d:%s" % (value, message) 
     s.close() 
     conn.close() 
     sys.exit(1) 

if __name__ == '__main__': 
    # power by cppfun.com 
    app() 
# also you can change it yourself
