Flask--session
session
和Django中设置session不同,Flask中的session被单独提出来了,不在request中;并且使用前需要设置secret_key参数
from flask import Flask,render_template,request,redirect,session
app = Flask(__name__)
app.secret_key = "xxxxx" # 值可以随便写
@app.route("/login",methods=["POST","GET"])
def login():
if request.method == "GET":
return render_template("login.html")
user = request.form.get("user")
pwd = request.form.get("pwd")
if user == "xxx" and pwd == "123":
session["name"] = user # 设置session
return redirect("/index/")
error = "用户名或密码错误"
return render_template("login.html",error=error)
Flask的session存储在浏览器端,再次请求时会携带session,服务端进行解密校验
