Here, we describe how to use Python to communicate with the front-end JS.
WebSocket after the handshake is completed using the HTTP protocol, WebSocket communication is not made directly through HTTP.
So, use WebSocket roughly two steps: Use HTTP handshake, communication.

Here, how to use Python to communicate with the front-end JS.
WebSocket use the HTTP protocol to complete the handshake, do not direct websocket communication via HTTP.
So, using WebSocket is roughly two steps: using HTTP handshake, communication.
JS processing websocket to use the WS module, Python processing uses the
. It generally does not require the user to enter a login password to access files and services on the server. HTTP File UploadThe main loss request is to obtain a Web page (file download).FTP of File transferOn the ground floor, FTP uses only TCP (see section on previous network programming)-it does not use UDP. Also, FTP is a customerThe "different" example of end/server programming. Both the client and the server use two sockets to communicate: one
UDP is widely used in network applications that need to transmit data to each other, such as the UDP protocol used by QQ. In the case of bad network quality, the packet loss is very serious when using UDP protocol, but the UDP occupies less resources and the processing speed is fast, UDP is still a common protocol for data transmission.
Here's the code to implement the UDP server in Python:
Copy Code code as follows:

This article illustrates the way Python implements TCP server-side and client. Share to everyone for your reference. Specifically as follows:

Recently in research smartfoxserver 2x, this is a network development framework for networked games, the server is developed based on the Java Netty Framework, the client supports Flash,unity, iOS, Android (Java), C + +. Wait a minuteIs that Python is not supportedHow can it be less python? So I put the Java client bac

In the previous article, we only implemented a simple http client function. The request also provides various functions such as keep alive, SSL, multi-File Upload, cookie management, and http requests header management, all functions are supported in r

Recently learning Python, but also need to learn some of the network programming knowledge, wrote a simple chat room program. The program is divided into two Python files, one is server.py and the other is client.py.The process for socket programming is as follows: Service side:1. The server needs to create a socket object. (Socket ())2. Bind the IP address and port number for this socket object. (Bind (
This article mainly introduces the simple file transfer Server and Client implemented by Python. This article provides the implementation code of the Server and Client, if you need a friend, you can refer to the question or question (for the question and process, see the java version). I feel that I have not written any new ideas in java. I just learned
This article illustrates how Python implements the Telnet client. Share to everyone for your reference. Specifically as follows:
Python implementation of the Telnet client, Python with a telnetlib module, you can use its Telnet class to achieve Telnet operation

The example in this article describes how the Python server communicates with the Android client socket. Share to everyone for your reference. The implementation methods are as follows:
First, the server side is done with Python, and here's the Python code:
Copy Code code as follows:

This article describes the Python police and thieves of one of the implementation of client-server communication, sharing for everyone to reference. The specific methods are analyzed as follows:
This example comes from the ISCC 2012 crack off the fourth questionThe aim is to realize a thief and communicate with police by reverse police.

Datagramrequesthandler.
Streamrequesthandler/datagramrequesthandler: Service processing tools for TCP/UDP servers.
Below we formally enter the topic, here we adopt Streamrequesthandler and Threadingtcpserver to implement the client and server concurrent connection non-blocking socket.
Threadingtcpserver derived from threadingmixin, mainly to achieve the core process of combining threading functionality.
Streamrequesthandler is primarily used for
