Want to connect a client script to your Flask backend? Python’s requests library makes it super easy to send HTTP requests to your Flask server. Here’s a quick example:
Flask Server (server.py):
from flask import Flask, request, jsonify
app = Flask(__name__)
@app.route('/submit', methods=['POST'])
def handle_submit():
data = request.get_json()
return jsonify({"message": f"Received {data['name']}!"})
if __name__ == '__main__':
app.run(debug=True)
Client Script (client.py):
import requests
data = {"name": "Alice"}
response = requests.post("http://127.0.0.1:5000/submit", json=data)
print(response.json())
✅ How it works:
- The Flask server listens for a POST request at
/submit. - The client sends JSON data using
requests.post(). - Flask reads it via
request.get_json()and responds with a message.
This setup is perfect for student dashboards, form submissions, or simple APIs.
