python socket实现一个http请求 支持gzip压缩
作者:admin 日期:2015-10-24
python用socket实现发送和接收一个http请求,自动处理gzip。直接上代码。
# -*- coding: utf-8 -*-
import zlib, socket
conn = socket.create_connection( ("www.zeroplace.cn", 80) );
data = "''GET / HTTP/1.1
Host: www.zeroplace.cn
Accept-Encoding: gzip, deflate
'''
print data
conn.send(data + "\r\n")
recv_data = ""
header = None
body = None
length = 0
headers = {}
buf = conn.recv(1024)
html = ""
while True:
recv_data += buf
if header is None:
index = recv_data.find("\r\n\r\n")
if index >= 0:
header = recv_data[0:index];
recv_data = recv_data[index+4:];
header_lines = header.split("\r\n")
status_line = header_lines[0]
print status_line
for line in header_lines[1:]:
print line
line = line.strip("\r\n")
if len(line) == 0:
continue
colonIndex = line.find(":")
fieldName = line[:colonIndex]
fieldValue = line[colonIndex+1:].strip()
headers[fieldName] = fieldValue
# print headers
length = int(headers['Content-Length'])
if header is not None and len(recv_data) >= length:
break;
else:
buf = conn.recv(1024)
if 'Content-Encoding' in headers and headers['Content-Encoding'] == 'gzip' :
html = zlib.decompress(recv_data, 16+zlib.MAX_WBITS)
else:
html = recv_data
print html
conn.close()
