Flask中cookie的使用

设置cookie

from flask import Flask,make_response

app = Flask(__name__)

@app.route("/set_cookie")
def set_cookie():
    resp = make_response("success")
    # 设置cookie,默认有效期是临时cookie，浏览器关闭就失效
    resp.set_cookie("itcase","python")
    # 通过max_age 设置有效期，但是为秒
    resp.set_cookie("itcase1", "python1",max_age = 3600)
    resp.headers["Set-Cookie"] = "itcase3=python3; Expires=Sat, 16-Sep-2020 23:19:28 GMT; Max-Age=3600; Path=/"

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