如何RESTful返回随机项？

import random

random_number = random.randint(1, 100)

import redis

r = redis.Redis(host='localhost', port=6379, db=0)

r.set('random_number', random_number)

from flask import Flask, jsonify

app = Flask(__name__)

@app.route('/random', methods=['GET'])
def get_random_number():
    # 从缓存中获取随机数
    random_number = r.get('random_number')

    # 将随机数作为JSON响应返回
    return jsonify({'random_number': random_number})

fetch('/random')
  .then(response => response.json())
  .then(data => console.log(data.random_number))
