1. 设置cookie,默认有效期是临时cookie，浏览器关闭就会失效

from flask import Flask,make_responseapp = Flask(__name__)@app.route("/set_cookie",methods=["GET"])
def set_cookie():resp = make_response("success")# 设置cookie，默认有效期是临时cookie，浏览器关闭就会失效resp.set_cookie("Zep","python")resp.set_cookie("Zep1", "python1")return respif __name__ == '__main__':app.run(debug=True)

2. 通过max_age设置有效期，单位：秒

3. 读取cookie的值

4. 删除cookie

5. 设置cookie的实质：在响应头中添加数据
