socket option header 지정 관련

[ socket ]

?

1 2 3 4 5 6 7 8 9 10 11 12

from socket import socket, AF_INET, SOCK_STREAM   host = '192.168.0.10' port = 80   request = 'data'   s = socket(AF_INET, SOCK_STREAM) s.connect((host, port)) s.send(request) response = s.recv(1000) s.close()

[ urllib2 ] 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

import urllib import urllib2    url = "http://testurl"     #########    GET    ######### req = urllib2.Request(url)   #########    POST   ######### data = {'id':'TestID', 'pw':'TestPW'} data = urllib.urlencode(data) req = urllib2.Request(url, data)   ######## Header data ####### user_agent = 'test agent' cookie = 'abc' req.add_header('User-agent', user_agent) req.add_header('cookie', cookie)   ####### Proxy Setting ####### proxy = urllib2.ProxyHandler({'http': '127.0.0.1:8080'}) opener = urllib2.build_opener(proxy) urllib2.install_opener(opener)     ############################# response = urllib2.urlopen(req) header = response.headers.headers data = response.read()

[ httplib ]

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

import httplib import urllib     url = 'www.test.com' conn = httplib.HTTPConnection(url)   #########    GET    ######### conn.request('GET', '/index.html')   #########    POST   ######### post_param = urllib.urlencode({'id':'test', 'pw':'test'}) headers = {'Cookie':'abcd'} conn.request('POST', '/index.html', post_param, headers)   ############################# response = conn.getresponse()   print response.status print response.reason print response.getheaders() print response.read()

urllib의 경우에는 user-agent 값이 디폴트로  "User-Agent: Python-urllib/1.17"가 되고 httplib는 따로 세팅해주지 않으면 존재하지 않는다.

추가

클라이언트

s = socket(AF_INET, SOCK_STREAM)

s.connect(('localhost', 9000))

s.send('HI')

s.close()

서버

from socket import *

s = socket(AF_INET, SOCK_STREAM)

s.bind(('localhost', 9000'))

s.listen(1)

conn, addr = s.accept()

...addr 에는 IP/PORT 정보 

conn.recv(1024)

conn.close()
