Sockets are essential for establishing connections and facilitating communication between two or more nodes over a network. Web browsing is an example of socket programming. The user requests the web server for information, and the server processes the request and provides the data. In Python, for ...
首先要创建 socket,用 Python 中 socket 模块的函数socket就可以完成: #Socket client example in pythonimportsocket#for sockets#create an AF_INET, STREAM socket (TCP)s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)print'Socket Created' 函数socket.socket创建一个 socket,返回该 socket 的描述符,...
# echo-server.py import socket HOST = "127.0.0.1" # Standard loopback interface address (localhost) PORT = 65432 # Port to listen on (non-privileged ports are > 1023) with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s: s.bind((HOST, PORT)) s.listen() conn, addr = s.a...
socket.socket()创建一个支持上下文管理器类型的 socket 对象,因此可以在 with 语句中使用它,没有必要去调用s.close(): withsocket.socket(socket.AF_INET,socket.SOCK_STREAM)ass:pass# Use the socket object without calling s.close(). 传递给socket()的参数指定地址族和 socket 类型。AF_INET指的是 IPv4...
server_socket.listen(2) conn, address = server_socket.accept() # accept new connection print("Connection from: " + str(address)) while True: # receive data stream. it won't accept data packet greater than 1024 bytes data = conn.recv(1024).decode() ...
In this example, socket.AF_INET was used (IPv4) in the call to socket(). You can see this in the Proto column: tcp4. The output above is trimmed to show the echo server only. You’ll likely see much more output, depending on the system you’re running it on. The things to ...

For example, to send "Hello, world!" via TCP to port 80 of the host with address 1.2.3.4, one might get a socket, connect it to the remote host, send the string, then close the socket: 1 2 3 4 Socket socket = getSocket(type = "TCP") connect(socket, address = "1.2.3.4",...
该module中主要的socket API函数有: socket() bind() listen() accept() connect() connect_ex() send() recv() close() Python提供了方便并且前后一致的API,这些API直接映射到系统调用,这些系统调用采用c实现。我们将在下一节 了解这些API是如何结合起来使用的。
