按例程，一步一步理解如何从SOCKET,TCP,HTTP,CGIHTTP进化的。
最终，静态文件和脚本分享，且能处理FORM提交和展示。
下一步，到数据库？？：）
A，SOCKET
#HTTPserver
import socket
HOST = ''
PORT = 8088
text_content = '''
HTTP/1.x 200 OK
Content-Type: text/html
<html>
<head>
<title>WOW</title>
</head>
<body>
<p>WOW, Python Server</p>
<form name='input', action='/' method='post'>
First name :<input type='text' name='firstname'><br>
<input type='submit' value='submit'>
</form>
</body>
</html>
'''
f = open('hello.jpg', 'rb')
pic_content = '''
HTTP/1.1 200 OK
Content-Type: image/jpeg
'''
pic_content = pic_content + f.read()
f.close()
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST, PORT))
print 'HTTPserver is start listen...'
while True:
s.listen(3)
conn, addr = s.accept()
request = conn.recv(1024)
print request.split(' ')
method = request.split(' ')[0]
src = request.split(' ')[1]
if method == 'GET':
if src == '/hello.jpg':
content = pic_content
else:
content = text_content
print 'Connetcted by', addr
print 'Request is:', request
conn.sendall(content)
if method == 'POST':
form = request.split('\r\n')
idx = form.index('')
entry = form[idx:]
value = entry[-1].split('=')[-1]
conn.sendall(text_content + '\n <p>' + value + '</p>')
conn.close()
B，TCP
#HTTPserver
#import socket
import SocketServer
HOST = ''
PORT = 8080
text_content = '''
HTTP/1.x 200 OK
Content-Type: text/html
<html>
<head>
<title>WOW</title>
</head>
<body>
<p>WOW, Python Server</p>
<form name='input', action='/' method='post'>
First name :<input type='text' name='firstname'><br>
<input type='submit' value='submit'>
</form>
</body>
</html>
'''
f = open('hello.jpg', 'rb')
pic_content = '''
HTTP/1.1 200 OK
Content-Type: image/jpeg
'''
pic_content = pic_content + f.read()
f.close()
class MyTCPHandler(SocketServer.BaseRequestHandler):
def handle(self):
print 'HTTPserver is start listen...'
request = self.request.recv(1024)
print 'Connetcted by', self.client_address[0]
print 'Request is:', request
method = request.split(' ')[0]
src = request.split(' ')[0]
if method == 'GET':
if src == '/hello.jpg':
content = pic_content
else:
content = text_content
self.request.sendall(content)
if method == 'POST':
form = request.split('\r\n')
idx = form.index('')
entry = form[idx:]
value = entry[-1].split('=')[-1]
self.request.sendall(text_content + '\n <p>' + value + '</p>')
server = SocketServer.TCPServer((HOST, PORT), MyTCPHandler)
server.serve_forever()
C，HTTP
#HTTPserver #import socket import SocketServer import SimpleHTTPServer HOST = '' PORT = 8088 server = SocketServer.TCPServer((HOST, PORT), SimpleHTTPServer.SimpleHTTPRequestHandler) server.serve_forever()
D，CGI
#HTTPserver #import socket import BaseHTTPServer import CGIHTTPServer HOST = '' PORT = 8088 server = BaseHTTPServer.HTTPServer((HOST, PORT), CGIHTTPServer.CGIHTTPRequestHandler) server.serve_forever()
（HTML及PY）
<head> <title>WOW</title> </head> <html> <p>Wow, Python Server</p> <IMG src="hello.jpg"/> <form name="input" action="cgi-bin/post.py" method="post"> First name:<input type="text" name="firstname"><br> <input type="submit" value="Submit"> </form> </html> ~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~ import cgi form = cgi.FieldStorage() print 'Content-Type: text/html' print print '<p>Hello world!</p>' print '<p>' + repr(form['firstname']) + '</p>'
