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>‘
