Http Methods Development Tutorials, Guides & Insights

If you're working in the browser, you can include Axios directly via a CDN:

<script src="https://cdn.jsdelivr.net/npm/axios/dist/axios.min.js"></script>

This REST API cheatsheet provides a comprehensive overview of the most commonly used REST API concepts, complete with examples to help you quickly find the information you need. Whether you're building or consuming APIs, this guide serves as a quick reference to help you work more efficiently with REST APIs.

Add the getBooks function to main.go:

func getBooks(w http.ResponseWriter, r *http.Request) {
	w.Header().Set("Content-Type", "application/json")
	json.NewEncoder(w).Encode(books)
}

from flask import Flask, jsonify, request, abort

app = Flask(__name__)

items = [
    {"id": 1, "name": "Item 1", "price": 100},
    {"id": 2, "name": "Item 2", "price": 150},
    {"id": 3, "name": "Item 3", "price": 200}
]

@app.route('/api/items', methods=['GET'])
def get_items():
    return jsonify(items)

@app.route('/api/items/<int:item_id>', methods=['GET'])
def get_item(item_id):
    item = next((item for item in items if item["id"] == item_id), None)
    if item is None:
        abort(404)
    return jsonify(item)

@app.route('/api/items', methods=['POST'])
def create_item():
    if not request.json or 'name' not in request.json or 'price' not in request.json:
        abort(400)
    new_item = {
        "id": items[-1]['id'] + 1 if items else 1,
        "name": request.json['name'],
        "price": request.json['price']
    }
    items.append(new_item)
    return jsonify(new_item), 201

@app.route('/api/items/<int:item_id>', methods=['PUT'])
def update_item(item_id):
    item = next((item for item in items if item["id"] == item_id), None)
    if item is None:
        abort(404)
    if not request.json:
        abort(400)
    item['name'] = request.json.get('name', item['name'])
    item['price'] = request.json.get('price', item['price'])
    return jsonify(item)

@app.route('/api/items/<int:item_id>', methods=['DELETE'])
def delete_item(item_id):
    item = next((item for item in items if item["id"] == item_id), None)
    if item is None:
        abort(404)
    items.remove(item)
    return jsonify({"result": True})

if __name__ == '__main__':
    app.run(debug=True)

You can use Postman or curl to test the API.
