I'd be happy to help! Please provide me with the Java code snippet that you would like me to explain.
const express = require('express');
const app = express();
// Sample customer data
const customers = [
{ id: 1, name: 'Alice', email: 'alice@example.com' },
{ id: 2, name: 'Bob', email: 'bob@example.com' },
];
// Endpoint to retrieve customer information
app.get('/customers/:id', (req, res) => {
const customerId = parseInt(req.params.id);
const customer = customers.find(cust => cust.id === customerId);
if (customer) {
res.json(customer);
} else {
res.status(404).json({ message: 'Customer not found' });
}
});
const PORT = 3000;
app.listen(PORT, () => {
console.log(`Server is running on port ${PORT}`);
});
This code snippet creates a simple Express API with an endpoint to retrieve customer information based on the customer ID provided in the URL. It defines a sample array of customers, sets up a GET endpoint /customers/:id
to handle the request, and returns the customer information if found or a 404 error if the customer is not found.
from flask import Flask, jsonify
app = Flask(__name__)
# Sample customer data
customers = {
1: {
"name": "Alice",
"age": 30,
"email": "alice@example.com"
},
2: {
"name": "Bob",
"age": 25,
"email": "bob@example.com"
}
}
# API endpoint to retrieve customer information
@app.route('/customer/<int:customer_id>', methods=['GET'])
def get_customer(customer_id):
if customer_id in customers:
return jsonify(customers[customer_id])
else:
return jsonify({"error": "Customer not found"}), 404
if __name__ == '__main__':
app.run(debug=True)
This Python Flask code sets up a simple API endpoint /customer/<customer_id>
to retrieve customer information. It defines a dictionary customers
with sample customer data and a route get_customer
that returns the customer information if the customer ID exists in the dictionary.
