第1关-创建流式套接字

#import socket module
from socket import *
serverSocket = socket(AF_INET, SOCK_STREAM) 
#Prepare a sever socket 
########## Begin ##########
serverSocket.bind(('127.0.0.1',6789))
serverSocket.listen(1)
########## End ##########
print(serverSocket)
serverSocket.close()

第2关-服务端获取连接请求

#import socket module
from socket import *
serverSocket = socket(AF_INET, SOCK_STREAM) 
#Prepare a sever socket 
serverSocket.bind(("127.0.0.1",6789))
serverSocket.listen(1)

#while True:
#Establish the connection
print('开始WEB服务...')

try:
    ########## Begin ##########
    connectionSocket, addr = serverSocket.accept()
    message = connectionSocket.recv(1024)
    ########## End ##########
    print(addr[0])
    print(message)
    connectionSocket.close()
except IOError:

        connectionSocket.close()
serverSocket.close()
