flask(四)之redis操作/配置静态文件路径

一.在utils包下创建**init**.py

文档树如下:

![这里写图片描述][70]  
如下:

import os
    
    from flask import Flask
    from flask_session import Session
    import redis
    
    from App.views import blue
    
    def create_app():
    
        BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
    
        template_dir = os.path.join(BASE_DIR, 'templates')
    
        static_dir = os.path.join(BASE_DIR, 'static')
        # 初始化app
        app = Flask(__name__, template_folder=template_dir, static_folder=static_dir)
        # 注册蓝图
        app.register_blueprint(blueprint=blue, url_prefix='/app/')
    
        # 设置密钥, 使用redis存储信息
        app.config['SECRET_KEY'] = 'secret_key'
        app.config['SESSION_TYPE'] = 'redis'
    
        #访问远程redis
        app.config['SESSION_REDIS'] = redis.Redis(host='114.116.4.186', port='6379',password='2905058')
    
        #定义前缀
        app.config['SESSION_KEY_PREFIX'] = 'flask'
    
        #第一种初始化app
        Session(app)
    
        #第二种方式
        # se = Session()
        # se.init_app(app)
    
        return app

在manage.py项目文件下为:

from flask_script import Manager
    
    from App import create_app
    
    app = create_app()
    
    # 将app交给manage进行管理
    manage = Manager(app=app)
    
    if __name__ == '__main__':
        manage.run()

在views.py中进行操作,存取数据,删除数据

import random
    
    from flask import Blueprint, render_template, request, session, redirect, url_for, make_response
    
    # 蓝图用于管理url
    blue = Blueprint('app', __name__)
    
    @blue.route('/login/', methods=['GET', 'POST'])
    def login():
        if request.method == 'GET':
            username = session.get('username')
            return render_template('login.html', username=username)
        elif request.method == 'POST':
            username =request.form.get('username')
            session['username'] = username
    
            return redirect(url_for('app.login'))
    
    @blue.route('/getresponse/')
    def get_resopnse():
    
        response = make_response('<h2>我是大帅比</h2>')
        ticket = ''
        s = 'qwertyuiopasdfghjklzxcvbnm1234567890'
        for i in range(20):
            ticket += random.choice(s)
        response.set_cookie('ticket', ticket)
        return response
    
    @blue.route('/deletecookie/')
    def del_cookie():
    
        response = make_response('<h2>我是大帅比1</h2>')
    
        response.delete_cookie('ticket')
        return response
