从 Python TCP Web 服务器打印出地址

Question

我能够打印出本地主机 127.0.0.1，很好，但是我无法打印出端口 61627，如下所示。正如这个中提到的，我设置了 outputdata = serverSocket.getsockname() 和 serverSocket.getpeername() 但都未能 return 端口。

#import socket module
from socket import *

serverSocket = socket(AF_INET, SOCK_STREAM)
serverSocket.bind(('127.0.0.1', 80))
serverSocket.listen(1)

while True:
    print ('Ready to serve...')
    connectionSocket, addr = serverSocket.accept()
    print ('Required connection', addr)

    try:
        message = connectionSocket.recv(1024)
        outputdata = addr
        connectionSocket.send(('HTTP/1.0 200 OK\r\n\r\n').encode('utf-8'))
        for i in range(0, len(outputdata)):
            connectionSocket.send(outputdata[i].encode('utf-8'))

        connectionSocket.close()
    except IOError:
        connectionSocket.send(('404 Not Found').encode('utf-8'))
        connectionSocket.close()
        serverSocket.close()

Answer 1

考虑到上述脚本属于服务器，您可以尝试添加 serversocket.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1) 绑定前

Answer 2

我删除了 for 循环并将 connectionSocket.send(outputdata[i].encode('utf-8')) 替换为 connectionSocket.sendall(str(outputdata).encode('utf-8'))。我已将输出数据转换为字符串，sendall return 是整个元组。我即兴 Python TCP WebServer 的最终代码是：

from socket import *

serverSocket = socket(AF_INET, SOCK_STREAM)
serverSocket.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
serverSocket.bind(('127.0.0.1', 80))
serverSocket.listen(1)

while True:
    print ('Ready to serve...')
    connectionSocket, addr = serverSocket.accept()
    print ('Required connection', addr)

    try:
        message = connectionSocket.recv(1024)
        outputdata = addr
        connectionSocket.send(('HTTP/1.0 200 OK\r\n\r\n').encode('utf-8'))
        connectionSocket.sendall(str(outputdata).encode('utf-8'))
        print(outputdata)
        connectionSocket.close()
    except IOError:
        connectionSocket.send(('404 Not Found').encode('utf-8'))
        connectionSocket.close()
        serverSocket.close()

请问return这个到localhost
