Flask API -请求后执行操作，优先级较低

from flask import Flask, jsonify

@app.route('/api/data', methods=['GET'])
def get_data():
    # 假设这里是处理请求的主要逻辑
    data = {'message': 'Hello, World!'}
    return jsonify(data), 200

@app.after_request
def after_request_func(response):
    # 这里可以执行一些优先级较低的操作
    print("执行请求后的操作")
    # 例如，记录响应时间或状态码
    print(f"Response status: {response.status}")
