Python httplib模組使用執行個體

httplib模組是一個底層基礎模組,實現的功能比較少,正常情況下比較少用到.推薦用urllib, urllib2, httplib2.

HTTPConnection 對象

class httplib.HTTPConnection(host[, port[, strict[, timeout[, source_address]]]])

建立HTTPConnection對象

HTTPConnection.request(method, url[, body[, headers]])

發送請求

HTTPConnection.getresponse()

獲得響應

HTTPResponse對象

HTTPResponse.read([amt])
Reads and returns the response body, or up to the next amt bytes.

HTTPResponse.getheader(name[, default])

獲得指定頭資訊

HTTPResponse.getheaders()

獲得(header, value)元組的列表

HTTPResponse.fileno()

獲得底層socket檔案描述符

HTTPResponse.msg

獲得頭內容

HTTPResponse.version

獲得頭http版本

HTTPResponse.status

獲得返回狀態代碼

HTTPResponse.reason

獲得返回說明

執行個體

代碼如下:

#!/usr/bin/python
import httplib

conn = httplib.HTTPConnection("www.bitsCN.com")
conn.request("GET", "/")
r1 = conn.getresponse()

print r1.status, r1.reason
print '-' * 40

headers = r1.getheaders()
for h in headers:
print h
print '-' * 40

print r1.msg

輸出:

代碼如下:

200 OK
