用python实现HTTP协议
1.有时间就来研究研究python中的lib包下面的所有模块代码,写得相当有水平的!
实现一个简单的HTTP服务器
#Copyright Jon Berg , turtlemeat.com
import string,cgi,time
from os import curdir, sep
from BaseHTTPServer import BaseHTTPRequestHandler, HTTPServer
#import pri
class MyHandler(BaseHTTPRequestHandler):
def do_GET(self):
try:
if self.path.endswith(".html"):
f = open(curdir + sep + self.path) #self.path has /test.html
#note that this potentially makes every file on your computer readable by the internet
self.send_response(200)
self.send_header('Content-type', 'text/html')
self.end_headers()
self.wfile.write(f.read())
f.close()
return
if self.path.endswith(".esp"): #our dynamic content
self.send_response(200)
self.send_header('Content-type', 'text/html')
self.end_headers()
self.wfile.write("hey, today is the" + str(time.localtime()[7]))
self.wfile.write(" day in the year " + str(time.localtime()[0]))
return
return
except IOError:
self.send_error(404,'File Not Found: %s' % self.path)
def do_POST(self):
global rootnode
try:
ctype, pdict = cgi.parse_header(self.headers.getheader('content-type'))
if ctype == 'multipart/form-data':
query=cgi.parse_multipart(self.rfile, pdict)
self.send_response(301)
self.end_headers()
upfilecontent = query.get('upfile')
print "filecontent", upfilecontent[0]
self.wfile.write("POST OK.
");
self.wfile.write(upfilecontent[0]);
except :
pass
def main():
try:
server = HTTPServer(('', 80), MyHandler)
print 'started httpserver...'
server.serve_forever()
except KeyboardInterrupt:
print '^C received, shutting down server'
server.socket.close()
if __name__ == '__main__':
main()
处理客户端的GET与POST请求是通过MyHandler方法进行处理的!
