Introduction to Python 3 HTTP Server
Python 3 http server is a built-in Python module that provides typical GET and HEAD request handlers. Any directory on our system can be turned into a web server with this module. We must put one line of code in our terminal to set up this HTTP server. GET and HEAD are the only HTTP methods that Python HTTP Server provides.
What is a python 3 http server?
- As a result, it’s a useful tool for transferring files over the internet. In Python 3, the HTTP Server module has been renamed the http server.
- A TCP socket address listens for incoming http requests (IP address and a port number). Then, it responds to the user’s request.
- HTTP Server in Python 3 is a built-in HTTP server that requires no installation or configuration. HTTP Server is, therefore, a highly useful utility. With the Python HTTP Server module, any directory can be turned into a simple HTTP web server.
- The HTTP server module includes a basic HTTP server with GET and HEAD request handlers.
- The HTTP Server module can create a web server from any directory on our system. To set up this HTTP server, we only need to input one line of code in our terminal.
- GET and HEAD are the only HTTP methods that Python HTTP Server provides. As a result, it’s a fantastic tool for transferring files across a network. The program, by default, launches a basic web server on port 8000.
- There are two approaches to setting up a web server in Python. First, python comes with a built-in web server. Then, with a one-liner, we can launch a web server.
- We can build our bespoke web server with unique features. We will find out how to do it in this article.
- Only our local network can access the web server in this case. A local host or a different network host might be used. With a VPN, we might serve it to people in different parts of the world.
How do we set up the python 3 http server?
- To avoid the problem of async queries, we should run such examples through a local webserver to test them. Python’s http server module is one of the simplest ways to accomplish this.
- The http server module in Python 3 is cleaner and offers explicit messages. However, upon quitting the keyboard, the python http server module does not reveal all of the python modules’ details; this is a cleaner way.
The below step shows how we set up the python 3 http server.
- In the first step, we check the version of python which we have installed in our system. If suppose we didn’t install python on our server, we must first install it in our system. We are checking the python version by using the following command.
# python3 –version
- Go on to the specified directory where directory. We have kept the file in the python310 location.
- Execute the below command to start the http server as follows.
python –m http.server
Create python 3 http server
- In Python, there are two approaches to setting up an http server. Python includes an http server by default. With a single line of code, we can start an http server. We can, however, develop an http server with unique features.
- In the below example, the web server can only be accessible from within our local network. This could be a local host or a network host. With a VPN, we could serve it across multiple locations.
- The http module in Python’s standard library makes creating an HTTP server a breeze. The http.server object, in particular, is what we’ll be using.
- The below step shows that creating an http server is as follows.
- We need to execute the following command to create an http server in python 3. We have created a server in the current directory without writing any code.
python –m http.server –cgi 8000
This will start an HTTP server on port 8000 that will serve the files in the current directory.
In this step, we are creating the module code as follows.
from http.server import BaseHTTPRequestHandler, HTTPServer class html(BaseHTTPRequestHandler): def do_GET (self): self.send_response (300) self.send_header ('python 3','text/html') self.end_headers () message = "Python 3 html server" self.wfile.write (bytes(message, "utf8")) with HTTPServer (('', 7000), handler) as server: server.serve_forever ()
- Using an HTTP server to test Android, PC, or Web apps locally during development can be beneficial. It can also transfer files between two devices connected by a LAN or WLAN.
- The HTTP Web Server is a program that runs on a computer, listens for incoming HTTP requests from a certain IP and Port number, and then responds to the request.
- Python features a built-in web server that may be used for simple client-server communication and is included in the standard library.
- The two most important functions for building a web server are http.server and socket server. In addition, the port number might be explicitly specified in the software that connects to the web server.
Python 3 http server example
- The below example shows the http server as follows. To create an http server example, first, we need to start the server using the python command.
- The below example shows examples of SSL support as follows.
from http.server import HTTPServer, BaseHTTPRequestHandler import ssl httpd = HTTPServer(('localhost', 4443), BaseHTTPRequestHandler) httpd.socket = ssl.wrap_socket (httpd.socket, keyfile = "key.pem", certfile = 'cert.pem', server_side = True) httpd.serve_forever ()
An HTTP web server is a process that runs on our computer that performs two functions. First, a built-in Python module provides typical GET and HEAD request handlers. The HTTP server module includes a basic HTTP server with GET and HEAD request handlers.
