😃0 前言与开发环境

前言

这篇文章把自己今年寒假花了20天做的一个网站放出来。这个网站就是用来练练手感的,接下来会重新做一个属于我的个人网站,主题还没有想好,但是应该是类似于一个个人博客吧。后面做网站时会一直更新进度,感兴趣的小伙伴可以关注我了解后续,这个送给女朋友的就不详解了,直接放置源码,可以直接运行,当做一个参考。

开发环境
开发语言:python 3.8
开发框架:Flask
开发工具:PyCharm专业版
虚拟环境工具:Anaconda
浏览器:谷歌浏览器

😃1 运行结果图

主页

登录界面

注册界面

照片墙

想去的地方(挪威)

留言(无法提交)

浪漫烟花(带背景音乐)

注销

😃2 代码结构

一个app文件夹用来存放各个功能(忘记术语叫啥了),对应上面展示的几个功能。static文件夹存放静态文件,具体包括css文件,js文件和html文件以及图片和背景音乐。当然还有模型文件models.py存放数据库模型。

然后是config.py存放一些要用的配置类,manager.py作为主文件用于启动整个项目。

😃3 config.py配置文件

先从配置信息开始讲起吧。这个网站我用到的配置信息只有连接MySQL要用的一些相关信息,比较简单。

# coding:   utf-8
# 作者(@Author):   Messimeimei
# 创建时间(@Created_time): 2023/1/3 15:08

"""各种配置类"""


class BaseConfig(object):
    """所有配置类的基类"""
    SECRET_KEY = "LOVE"
    DEBUG = True
    TESTING = False
    VISIT_TIME = 0  # 网站访问次数
    # 数据库配置
    SQLALCHEMY_DATABASE_URI = "mysql+pymysql://root:这里换成自己的MySQL密码@localhost/personalwebsite"
    SQLALCHEMY_TRACK_MODIFICATIONS = False  # 是否追踪数据库的修改


class ProductionConfig(BaseConfig):
    """生产环境下的配置类"""
    DEBUG = False


class DevelopmentConfig(BaseConfig):
    """开发模式下的配置类"""
    DEBUG = True
    TESTING = True

然后我是使用的Navicat这个工具用来可视化操作MySQL的。就是下面这个家伙啦,可以在网上找到破解版的,如果想和我用一样的话,这里也有百度网盘的下载链接:

链接: https://pan.baidu.***/s/1WqS8H2fHAwkPm76O-7OClg?pwd=9rlv
提取码:9rlv
--来自百度网盘超级会员V3的分享

打开Navicat可以看到我创建了一个名为personalwebsite的数据库,双击它可以看到

我创建了两个表,一个是存放用户登录信息的,另一个message本来打算存放留言的,但是后面没用到大家可以不用管。

😃4 app包详解

这个包里面包含了整个网页代码,因此是本次项目的大头,我将按照登录注册功能、照片墙功能、我说功能、我想去的地方功能和浪漫烟花功能的顺序进行讲解。另外项目采用蓝图的方式开发,每次搞定完一个功能,就会在app包下面的__init__.py文件中添加相应的信息。这样方便管理整个项目结构,使之整洁、易于修改,可扩展性也很好。

📜4.1 登录注册功能

登录注册功能在app_login包中,里面一共两个文件,分别是__init__.py和view.py视图文件。先看__init__.py文件。

# coding:   utf-8
# 作者(@Author):   Messimeimei
# 创建时间(@Created_time): 2023/1/8 23:19

"""登录视图的蓝图"""
from flask import Blueprint

login = Blueprint("login", __name__)
from . import view

在app_login/__init__.py文件中我创建了一个登录视图的蓝图。接下来看登录注册的视图文件

首先导入了实现登录要用的一些Flask提供的模块,比如login_required, login_user, logout_user。具体功能我就不细讲了。然后导入了跳转网页要用的request, render_template, redirect, url_for, flash,还导入了数据库模型User和刚刚创建的蓝图login,最后从app包下的__init__.py中导入了管理登录用的login_manager,这个等会展示app/__init__.py的时候会看得到。

# coding:   utf-8
# 作者(@Author):   Messimeimei
# 创建时间(@Created_time): 2023/1/6 11:39

"""登录的视图函数"""
from flask import request, render_template, redirect, url_for, flash
from flask_login import login_required, login_user, logout_user
from . import login
from app.models import User
from app import login_manager


@login_manager.user_loader
def load_user(user_id):  # 创建用户加载回调函数,接受用户 ID 作为参数
    user = User.query.get(int(user_id))  # 用 ID 作为 User 模型的主键查询对应的用户
    return user  # 返回用户对象


@login.route('/index', methods=['GET', 'POST'])
@login_required
def index():
    return render_template('index.html')


@login.route('/register', methods=['GET', 'POST'])
def register():
    # 如果请求为post
    if request.method == 'POST':
        count = request.form.get('count')
        password = request.form.get('password')
        repassword = request.form.get('repassword')
        from app import db
        if password == repassword:
            user = User(count, password)
            user.set_password(password)
            db.session.add(user)
            db.session.***mit()
            return redirect(url_for("login.login_"))
        else:
            flash("两次密码不一致!")
            return render_template("register.html")
    return render_template('register.html')


@login.route('/', methods=['GET', 'POST'])
@login.route('/login', methods=['GET', 'POST'])
def login_():
    if request.method == 'POST':
        count = request.form['count']
        password = request.form['password']
        if not count or not password:
            flash('请输入账号和密码!')
            return redirect(url_for('login.login_'))
        user = User.query.filter_by(count=count).first()

        if not user:
            flash("用户不存在")
            return redirect(url_for('login.login_'))

        if count == user.count and user.check_password(password):
            login_user(user)  # 登入用户
            return redirect(url_for('login.index'))  # 重定向到主页

        flash('账号或密码不正确, 请重新登录!')  # 如果验证失败,显示错误消息
        return redirect(url_for('login.login_'))  # 重定向回登录页面
    return render_template('login.html')


@login.route('/logout', methods=['GET','POST'])
@login_required
def logout():
    logout_user()
    return redirect(url_for('login.login_'))

导入需要的模块和函数后,用login_manager作为修饰器管理用户登录,具体就是从数据库中查询信息判断是否存在用户,可以看其他博客了解详情。然后是分别用对应的修饰器修饰主页、注册页面、登录页面和注销页面。

📟4.2 照片墙功能

照片墙功能在app_photo_wall包中,里面一共两个文件,分别是__init__.py和view.py视图文件。先看__init__.py文件。

在app_photo_wall/__init__.py文件中我创建了一个照片墙视图的蓝图。接下来看照片墙的视图文件

    return render_template('photo_wall.html')

照片墙后端很简单,主要是靠前端实现的,下面给出前端代码

💻4.6 models.py模型文件

这里创建了User和Message数据库模型,也就是对应数据库里的两张表。其中第一个模型和登录也是有关联的,都是Flask自带的模块。

🔧4.7 __init__.py文件

这里完成对整个项目的蓝图的注册,配置信息和初始化数据库。

😃5 manager.py 启动项目

从app/__init__.py导入create()函数用于启动,同时设置了错误页面。
