一、设置、获取和删除cookie的使用
1、设置cookie值（需要先前设置make_response对象）
from flask import Flask, make_response
app = Flask(__name__, template_folder='templates', static_url_path='/static')
@app.route('/set_cookie')
def set_cookie():
resp = make_response("成功设置cookie")
#设置cookie,默认有效期是临时cookie，浏览器关闭就失效
resp.set_cookie('cookie1', 'xiao1')
#max_age设置有效期，单位：秒
resp.set_cookie('cookie2', 'xiao2', max_age=3600)
return resp
2、获取cookie值
from flask import Flask, make_response, request
app = Flask(__name__, template_folder='templates', static_url_path='/static')
@app.route('/get_cookie')
def get_cookie():
cookie_value = request.cookies.get('cookie1')
return '获取的cookie值为%s' % cookie_value
3、删除cookie值(需要先前设置make_response对象)
from flask import Flask, make_response, request
app = Flask(__name__, template_folder='templates', static_url_path='/static')
@app.route('/delete_cookie')
def delete_cookie():
resp = make_response('删除cookie成功')#浏览器没有删除，只是时间变了
resp.delete_cookie('cookie2')
return resp
二、设置、获取和删除session的使用
参考文档：https://www.jianshu.com/p/dacab2a6bc80
1、设置session值（必须要设置session的秘钥值）
Flask中session失效时间设置:https://www.jianshu.com/p/2e7cafd7df7d
from flask import Flask, session
app = Flask(__name__, template_folder='templates', static_url_path='/static')
app.secret_key = "sdsfdsgdfgdfgfh"
@app.route('/set_session')
def set_session():
session['name'] = '小伙子'
return 'session设置成功'
2、获取session值
from flask import Flask, session
app = Flask(__name__, template_folder='templates', static_url_path='/static')
app.secret_key = "sdsfdsgdfgdfgfh"
@app.route('/get_session')
def get_session():
session_name = session.get('name')
return session_name
3、删除session值
from flask import Flask, session
app = Flask(__name__, template_folder='templates', static_url_path='/static')
app.secret_key = "sdsfdsgdfgdfgfh"
@app.route('/delete_session')
def delete_session():
del session['name']
return 'session删除成功'
