CBV

Flask的路由系统有两种方式 :

　　@app.route()

　　app.add_url_rule()

from flask import Flask, views, render_template, redirect, request, session

class LoginView(views.MethodView):
    def get(self):
        return render_template("login.html")

    def post(self):
        if request.form["name"] == "qwe" and request.form["pwd"] == "qwe":
            session["user"] = "hd"
            return redirect("/reg")print(get_flashed_messages("错误"))
        return render_template("login.html")


app.add_url_rule("/login", view_func=LoginView.as_view("login"))
