👉 文章简介：献给女友的简单网站源代码
😃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

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.com/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 Blueprintlogin = 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postif request.method == 'POST':count = request.form.get('count')password = request.form.get('password')repassword = request.form.get('repassword')from app import dbif password == repassword:user = User(count, password)user.set_password(password)db.session.add(user)db.session.commit()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。
下面给出要用到的前端文件
