由于百度贴吧的源码非常庞大且复杂,这里仅提供一个简化版的示例,仅供参考,这个示例使用Python和Flask框架实现一个简单的论坛系统,包括用户注册、登录、发帖和查看帖子功能。
确保已经安装了Flask库,如果没有安装,可以使用以下命令安装:
pip install flask
创建一个名为app.py
的文件,然后将以下代码复制到文件中:
from flask import Flask, render_template, request, redirect, url_for, flash, session
from flask_sqlalchemy import SQLAlchemy
from werkzeug.security import generate_password_hash, check_password_hash
app = Flask(__name__)
app.config['SECRET_KEY'] = 'mysecretkey'
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///forum.db'
db = SQLAlchemy(app)
class User(db.Model):
id = db.Column(db.Integer, primary_key=True)
username = db.Column(db.String(80), unique=True, nullable=False)
password = db.Column(db.String(120), nullable=False)
class Post(db.Model):
id = db.Column(db.Integer, primary_key=True)
title = db.Column(db.String(100), nullable=False)
content = db.Column(db.Text, nullable=False)
user_id = db.Column(db.Integer, db.ForeignKey('user.id'), nullable=False)
@app.route('/')
def index():
posts = Post.query.all()
return render_template('index.html', posts=posts)
@app.route('/register', methods=['GET', 'POST'])
def register():
if request.method == 'POST':
username = request.form['username']
password = request.form['password']
hashed_password = generate_password_hash(password, method='sha256')
new_user = User(username=username, password=hashed_password)
db.session.add(new_user)
db.session.commit()
flash('注册成功,请登录!')
return redirect(url_for('login'))
return render_template('register.html')
@app.route('/login', methods=['GET', 'POST'])
def login():
if request.method == 'POST':
username = request.form['username']
password = request.form['password']
user = User.query.filter_by(username=username).first()
if user and check_password_hash(user.password, password):
session['user_id'] = user.id
flash('登录成功!')
return redirect(url_for('index'))
else:
flash('用户名或密码错误,请重试!')
return render_template('login.html')
@app.route('/logout')
def logout():
session.pop('user_id', None)
flash('已退出登录!')
return redirect(url_for('index'))
@app.route('/create', methods=['GET', 'POST'])
def create():
if 'user_id' not in session:
flash('请先登录!')
return redirect(url_for('login'))
if request.method == 'POST':
title = request.form['title']
content = request.form['content']
new_post = Post(title=title, content=content, user_id=session['user_id'])
db.session.add(new_post)
db.session.commit()
flash('帖子发布成功!')
return redirect(url_for('index'))
return render_template('create.html')
if __name__ == '__main__':
db.create_all()
app.run(debug=True)
创建以下HTML模板文件:
1、index.html
显示所有帖子的列表:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF8">
<title>论坛首页</title>
</head>
<body>
<h1>欢迎来到论坛!</h1>
{% for post in posts %}
<div>
<h2>{{ post.title }}</h2>
<p>{{ post.content }}</p>
<p>作者:{{ post.user.username }}</p>
</div>
{% endfor %}
<a href="{{ url_for('create') }}">发帖</a>
<a href="{{ url_for('login') }}">登录</a>
<a href="{{ url_for('register') }}">注册</a>
</body>
</html>
2、register.html
用户注册表单:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF8">
<title>注册</title>
</head>
<body>
<h1>注册</h1>
<form action="{{ url_for('register') }}" method="post">
<label for="username">用户名:</label>
<input type="text" name="username" required>
<br>
<label for="password">密码:</label>
<input type="password" name="password" required>
<br>
<input type="submit" value="注册">
</form>
<a href="{{ url_for('login') }}">已有账号?登录</a>
</body>
</html>
3、login.html
用户登录表单:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF8">
<title>登录</title>
</head>
<body>
<h1>登录</h1>
<form action="{{ url_for('login') }}" method="post">
<label for="username">用户名:</label>
<input type="text" name="username" required>
<br>
<label for="password">密码:</label>
<input type="password" name="password" required>
<br>
<input type="submit" value="登录">
</form>
<a href="{{ url_for('register') }}">还没有账号?注册</a>
</body>
</html>
4、create.html
发帖表单:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF8">
<title>发帖</title>
</head>
<body>
<h1>发帖</h1>
<form action="{{ url_for('create') }}" method="post">
<label for="title">标题:</label>
<input type="text" name="title" required>
<br>
<label for="content">内容:</label>
<textarea name="content" rows="10" cols="30" required></textarea>
<br>
<input type="submit" value="发布">
</form>
<a href="{{ url_for('index') }}">返回首页</a>
</body>
</html>
运行app.py
文件,然后在浏览器中访问http://localhost:5000
即可看到论坛的首页,用户可以注册、登录、发帖和查看帖子,这个示例仅用于演示目的,实际生产环境中需要考虑更多的安全性和功能完善。
