Building REST API is a construn task in web development, allowing different applications to o communicate over thee internet. Python, combined with the Flask framework, provides a simple andd efficient way te kreate these API. Flask 's lightweight nature makees it ideal for small to medium- sized projects.

Setting Up Flask

Tu startbuilding a REST API wigh Flask, first install thee Flask package using pip:

Xi1; Xi1; FLT: 0 Xi3; Xi3; pip install Flask Xi1; Xi1; FLT: 1 Xi3; Xi3;

Next, create a new Python file and import Flask. Initializate thee app and define routes to handle API requests.

Creating API Endpoints

Endpoints are e URL s that respond to specific HTTP methods such as GET, POST, PUT, and DELETE. Flask wykorzystuje dekoratorów to definiować te routy.

For example, a simple endpoint to retrievee data might look like:

Xi1; Xi1; FLT: 0 Xi3; Xi3; frem flask import Flask, jsonify Xi1; Xi1; FLT: 1 Xi3; Xi3; Xi3;

Xion1; Xion1; FLT: 0 Xion3; Xion3; app = Flask (_ _ name _ _ _) Xion1; FLT: 1 Xion3; Xion3;

(España):

Xi1; Xi1; FLT: 0 Xi3; Xi3; def get _ data (): Xi1; Xi1; FLT: 1 Xi3; Xi3; Xi3;

Xion1; Xion1; FLT: 0 Xion3; Xion3; data = {Xion3; message Xion1;: Xion1; Xion1; FLT: 1 Xion3; Xion3; Xion3;

Xiv1; Xiv1; FLT: 0 Xiv3; Xiv3; return jsonify (data) Xiv1; Xiv1; FLT: 1 Xiv3; Xiv3; Xiv3;

Running thee API

Tu run thee Flask application, include thee following code at thee end of your script:

Xiv1; Xiv1; FLT: 0 Xiv3; Xiv3; if _ _ _ name _ _ = = Xiv3; _ main _ _ Xiv3;: Xiv1; FLT: 1 Xiv3; Xiv3; Xiv3;

Xion1; Xion1; FLT: 0 Xion3; Xion3; app.run (debug = True) Xion1; Xion1; FLT: 1 Xion3; Xion3; Xion3;

Testing thee API

Once thee server is running, you can tect the API by nawigating to do1; indi1; FLT: 0 contex3; indis3; http: / / 127.0.1: 5000 / api / data context 1; indi1; FLT: 1 context 3; indis3; in a web browser or using tools like Postman or curl.

  • Start thee Flask server
  • Open a browser or API client
  • Send a GET request to the endpoint
  • Odbiorca JSON odpowiada
