😃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 = TrueTESTING = FalseVISIT_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 = Falseclass DevelopmentConfig(BaseConfig):"""开发模式下的配置类"""DEBUG = TrueTESTING = 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.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

index.html

当然其他的css文件，图片等后面会一并给出。

📟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。

# coding:   utf-8
# 作者(@Author):   Messimeimei
# 创建时间(@Created_time): 2023/1/13 16:10"""照片墙的蓝图"""
from flask import Blueprintphoto_wall = Blueprint("photo_wall", __name__)
from . import view

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

# coding:   utf-8
# 作者(@Author):   Messimeimei
# 创建时间(@Created_time): 2023/1/13 16:20"""照片墙的视图函数"""
from flask import render_template
from flask_login import login_required
from . import photo_wall@photo_wall.route('/photo_wall', methods=['GET', 'POST'])
@login_required
def index():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

photo_wall.html

当然大家可以换成自己想换的照片。

{% extends "base.html" %}
{% block title %}照片墙

😛4.3 我说功能

我说功能在app_isay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): 2023/1/22 8:52""""""
from flask import Blueprintisay = Blueprint("isay", __name__)
from . import view

在app_isay/__init__.py文件中我创建了一个我说视图的蓝图。接下来看我说功能的视图文件

# coding:   utf-8
# 作者(@Author):   Messimeimei
# 创建时间(@Created_time): 2023/1/22 8:52"""我说的视图函数"""
import time
from . import isay
from flask import request, render_template, session
from flask_login import login_required
from app.models import User, Message@isay.route('/isay', methods=['GET', 'POST'])
@login_required
def isay():from app import dbif request.method == 'POST':return render_template('isay.html')if request.method == 'POST':title = request.form.get("title")text = request.form.get("text")count = session.get('count')print(count)# 获取当前系统时间created_time = time.strftime("%Y-%m-%d %H:%M:%S")user = User.query.filter_by(count=count).first()message = Message(title=title, text=text, created_time=created_time, user_id=user.id)db.session.add(message)db.session.commit()blog = Message.query.filter(Message.created_time == created_time).first()return render_template('blogSuccess.html', title=title, id=message.id)

这个功能其实没开发好，大家可以不用管它或者自行完善也行。

✈4.4 想去的地方功能

想去的地方功能在app_togo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): 2023/1/23 11:34""""""
from flask import Blueprinttogo = Blueprint("togo", __name__)
from . import view

在app_togo/__init__.py文件中我创建了一个想去的地方视图的蓝图。接下来看看想去的地方功能的视图文件

# coding:   utf-8
# 作者(@Author):   Messimeimei
# 创建时间(@Created_time): 2023/1/23 11:35"""想去的地方"""
from . import togo
from flask import render_template@togo.route("/togo", methods=['POST', 'GET'])
def togo():return render_template("togo.html")

这个功能主要是在前端导入了谷歌地图的API，下面给出前端页面

togo.html

💥4.5 浪漫烟花功能

浪漫烟花功能在app_fireflower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

💻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。

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