网络编程：套接字基于TCP的应用（二--http传输server）

【1】接收http请求 

【2】查看http请求 

【3】返回一个网页给客户端

【server端】
from socket import * 

# 接收请求
# 查看请求
# 返回客户端段请求内容
def handleClient(connfd):
    request = connfd.recv(4096)
    # print("***********")
    # print(request)
    # print("************")
    #按照行切割请求
    request_lines = request.splitlines()
    for line in request_lines:
        print(line.decode())

    try:
        f = open('index.html')
    except IOError:
        response = "HTTP/1.1 303 Not Found\r\n"
        response += "\r\n"  #空行
        response += '''
                **************************
                Sorry, not found the page.
                **************************
                '''
    else:
        response = "HTTP/1.1 200  OK\r\n"
        response += '\r\n'
        response += f.read()
    finally:
        #发送给浏览器
        connfd.send(response.encode())



#创建套接字，调用handleClient完成功能
def main():
    #创建tcp套接字
    sock = socket()
    sock.setsockopt\
    (SOL_SOCKET,SO_REUSEADDR,1)
    sock.bind(('0.0.0.0',8000))
    sock.listen()
    while True:
        print("Listen the port 8000...")
        connfd,addr = sock.accept()
        #处理浏览器发来的请求
        handleClient(connfd)
        connfd.close()


if __name__ == "__main__":
    main()

 

【client端】
from socket import * 

#创建套接字
sock = socket()

#发起连接
sock.connect(('127.0.0.1',8888))

while True:
    #消息收发
    msg = input("Msg>>")
    if not msg:
        break
    sock.sendall(msg.encode())
    data = sock.recv(1024)
    print(data.decode())

sock.close()

 #===========================#

【httpserver2.py】
from socket import * 

#httpserver基本功能
#接收http请求，查看，返回一个页面
def handleClient(connfd):
    request = connfd.recv(4096)
    print("***************")
    print(request)
    print("***************")

    f = open('index.html','r')
    response = "HTTP/1.1 200 OK\r\n"
    response += "Content-Type: text/html\r\n"
    response += "\r\n"
    response += f.read() 
    connfd.send(response.encode())


sockfd = socket()
sockfd.setsockopt(SOL_SOCKET,SO_REUSEADDR,1)
sockfd.bind(('0.0.0.0',8000))
sockfd.listen(5)
while True:
    print("Listen the port 8000...")
    connfd,addr = sockfd.accept()
    handleClient(connfd)
    connfd.close()
