from flask import Flask, render_template, request, session, redirect app = Flask(__name__) app.secret_key = 'fdsa' app.debug = True @app.route('/login', methods=['GET', 'POST']) def login(): if request.method == 'GET': return render_template('login.html') usr = request.form.get('user') pwd = request.form.get('password') if usr == 'nihao' and pwd == '123': session['user_info'] = usr return redirect('/index') else: return render_template('login.html', msg='用户名密码错误') # 两种传值方式 取其一 # return render_template('login.html',**{'msg':'用户名密码错误'}) @app.route('/index') def index(): user_info = session.get('user_info') if not user_info: return redirect('/login') return '欢迎登录' @app.route('/logout') def logout(): del session['user_info'] return redirect('/login') if __name__ == '__main__': app.run()
