Python+Flask+MysqL设计网页

本人这学期在学习Python Web框架Flask下网站开发，这篇文章主要介绍在Web框架Flask下的网站开发入门实例，本文主要设计网友交流互动平台，已经实现了注册、登录、首页、发布、详情、个人中心功能

一、Flask简介

Flask 是一个 Python 实现的 Web 开发微框架。官网：http://flask.pocoo.org/

Flask主要有静态文件(staitc)、网页文件(templstes)、主py文(newproject)件以及配置文件(config)这四大部分。

static主要存放提供给网页css样式、js样式、以及图片。

网页文件是将效果展示给用户的。

主py文件的作用是实现用户与数据库的交互，实现网页上的功能，下图1.1为本实例的结构：

 

 

 

二、各模块效果图及重要代码

2.1父模板及首页

父模板是极其重要的，它是每个页面里相同的部分。在父模板中，我主要设计了页面背景，顶部导航栏，底部导航栏。首页里主要包含了三个模块，问题列表、内容推荐、以及底部图片导航。如图2.1.1所示：

代码：

# 将数据库查询结果传递到前端页面 Question.query.all(),问答排序
@app.route('/')
def index():
    context = {
        'questions': Question.query.order_by('-time').all()
    }
    return render_template('index.html', **context)

 

 

                                                       图2.1.1首页

 

2.2登录及注册

登录与注册页面的效果相似，在用户注册时需要判断密码是否一制，所以我加了一个js文件用以判断注册密码是否一致。登录页面需要判断用户名及密码是否与数据库中的数据匹配，所以在主py文件中，我分别用了两个函数来设置登录与注册，效果如图2.2.1、图2.2.2所示：

代码：

# 登录页面，用户将登录账号密码提交到数据库，如果数据库中存在该用户的用户名及id，返回首页
@app.route('/login', methods=['GET', 'POST'])
def login():

    if request.method == 'GET':

        return render_template('login.html')

    else:

        usern = request.form.get('username')

        passw = request.form.get('password')

        user = User.query.filter(User.username == usern).first()

        if user:

            if user.check_password(passw):

                session['user'] = usern

                session['id'] = user.id

                session.permanent = True

                return redirect(url_for('index'))  # 重定向到首页

            else:

                return u'password error'

        else:

            return u'username is not existed'

注册页面

@app.route('/register', methods=['GET', 'POST'])
def register():

    if request.method == 'GET':

        return render_template('register.html')

    else:

        username = request.form.get('username')

        password = request.form.get('password')

        user = User.query.filter(User.username == username).first()

        if user:

            return 'username existed'

        else:

            user = User(username=username, password=password)

            db.session.add(user)  # 数据库操作

            db.session.commit()

            return redirect(url_for('login'))  # 重定向到登录页

 

 

 

                                                    图2.2.1注册页面

 

 

 

                                                         图2.2.2.登录页面

 

2.3站友互动页面

站友互动页面可以发布问题，提交到数据库内。如图2.3.1所示：

代码：

# 问答页面
@app.route('/question', methods=['GET', 'POST'])
@loginFrist
def question():
    if request.method == 'GET':
        return render_template('question.html')
    else:
        title = request.form.get('title')
        detail = request.form.get('detail')
        classify = request.form.get('classify')
        author_id = User.query.filter(User.username == session.get('user')).first().id
        question = Question(title=title, detail=detail,classify=classify, author_id=author_id)
        db.session.add(question)
        db.session.commit()
    return redirect(url_for('index'))  # 重定向到登录页

                                                                                                                    图2.3.1站友发布页面

2.4内容详细页面

内容详细页面可以显示每个用户发布的内容，实现代码如下：

@app.route('/detail/<question_id>')
def detail(question_id):
    quest = Question.query.filter(Question.id == question_id).first()
    comments = Comment.query.filter(Comment.question_id == question_id).all()
    return render_template('detail.html', ques=quest, comments=comments)

2.5个人中心页面

个人中心可以显示用户的所有问题，所有评论以及个人信息，点击用户名可以跳转至个人中心页面

# 个人中心
@app.route('/usercenter/<user_id>/<tag>')
@loginFrist
def usercenter(user_id, tag):
    user = User.query.filter(User.id == user_id).first()
    context = {
        'user': user
    }
    if tag == '1':
        return render_template('usercenter1.html', **context)
    elif tag == '2':
        return render_template('usercenter2.html', **context)
    else:
        return render_template('usercenter3.html', **context)
