create a http server with a delete route in python

To create an HTTP server with a delete route in Python, we can use the http.server module, which provides classes for implementing HTTP servers (both standalone and threaded) and handlers. Since the module is built-in, we don't need to install any additional packages.

Here's an example code snippet that demonstrates how to create an HTTP server with a delete route:

main.py
from http.server import BaseHTTPRequestHandler, HTTPServer
import cgi

class DeleteHandler(BaseHTTPRequestHandler):
    
    def do_DELETE(self):
        if self.path == '/delete':
            # add your delete logic here

            self.send_response(200)
            self.send_header('Content-type', 'text/html')
            self.end_headers()
            self.wfile.write(b'Delete request processed')
        else:
            self.send_response(404)
            self.send_header('Content-type', 'text/html')
            self.end_headers()
            self.wfile.write(b'Route not found')

def run():
    server_address = ('', 8000)
    httpd = HTTPServer(server_address, DeleteHandler)
    print('Server running at localhost:8000...')
    httpd.serve_forever()

if __name__ == '__main__':
    run()

In this code, we define a DeleteHandler class that extends BaseHTTPRequestHandler, which is responsible for handling incoming HTTP requests. We override the do_DELETE method to implement the delete route logic.

In the do_DELETE method, we check if the request path is equal to '/delete'. If it is, we can add our delete logic, and then send a response indicating success (HTTP status code 200) and a message that the request has been processed. If the path is not '/delete', we send a 404 error response indicating that the route was not found.

The run function is responsible for starting the server. It creates an instance of HTTPServer and passes in the server address and DeleteHandler class. It then calls the serve_forever method, which starts the server listening on the specified port.

To test the server, you can send a DELETE request to http://localhost:8000/delete. You can use a tool like curl, or write a script that makes the request using Python's requests library. For example:

main.py
import requests

response = requests.delete('http://localhost:8000/delete')
print(response.content)

5 lines

Assuming the server is running, this code should output b'Delete request processed' to the console.
