开始学习进行玩前面项目  开始进军flask

flask是一个小型的web框架,,但是有很多第三方组件

最后组装组装就和django一样啦!!!!!!!

 

python install flask

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

# app = Flask(__name__,template_folder="templates",static_folder="staticccc",static_url_path=‘/vvvvv‘)
app = Flask(__name__,template_folder="templates",static_folder="static")
app.secret_key = ‘asdfasdf‘



@app.route(‘/login‘,methods=["GET","POST"])
def login():
    if request.method == ‘GET‘:
        return render_template(‘login.html‘)
    user = request.form.get(‘user‘)
    pwd = request.form.get(‘pwd‘)
    if user == ‘oldboy‘ and pwd == ‘666‘:
        session[‘user‘] = user
        return redirect(‘/index‘)
    return render_template(‘login.html‘,error=‘用户名或密码错误‘)
    # return render_template(‘login.html‘,**{"error":‘用户名或密码错误‘})

@app.route(‘/index‘)
def index():
    user = session.get(‘user‘)
    if not user:
        return redirect(‘/login‘)
    return render_template(‘index.html‘)

if __name__ == ‘__main__‘:
    app.run()
