俄文网站建设方案如何注册网站平台

本地短视频服务器

背景：我的NAS中存放了很多短视频，多到很多没看过，于是写了这个程序来随机查看并删除短视频

运行：

安装依赖后运行main.py

直接使用docker：

docker pull realwang/short_video

docker run -d -p 3000:3000 -v /path/to/your/video:/app/video realwang/short_video

功能

• 扫描本地视频和图片，并在网页上显示
• 在网页上 点赞和删除文件
• 上下滑动来切换文件
• 媒体文件放在video目录下
• 本地数据库

代码由4个文件组成

1.数据库操作

# database.pyimport sqlite3def init_db():conn = sqlite3.connect('media.db')c = conn.cursor()c.execute('''CREATE TABLE IF NOT EXISTS media(id INTEGER PRIMARY KEY, name TEXT, path TEXT, views INTEGER DEFAULT 0, likes INTEGER DEFAULT 0)''')conn.commit()conn.close()def add_media(name, path):try:conn = sqlite3.connect('media.db')c = conn.cursor()c.execute("INSERT INTO media (name, path) VALUES (?, ?)", (name, path))conn.commit()conn.close()return Trueexcept sqlite3.IntegrityError:# 处理重复键错误等数据库约束错误return Falseexcept Exception as e:print(f"Error inserting {name} into database: {str(e)}")return Falsedef update_views(media_id):conn = sqlite3.connect('media.db')c = conn.cursor()c.execute("UPDATE media SET views = views + 1 WHERE id = ?", (media_id,))conn.commit()conn.close()def update_likes(media_id):conn = sqlite3.connect('media.db')c = conn.cursor()c.execute("UPDATE media SET likes = likes + 1 WHERE id = ?", (media_id,))conn.commit()conn.close()def delete_media(media_id):conn = sqlite3.connect('media.db')c = conn.cursor()c.execute("DELETE FROM media WHERE id = ?", (media_id,))conn.commit()conn.close()def get_random_media():conn = sqlite3.connect('media.db')c = conn.cursor()c.execute("SELECT id, name, path FROM media ORDER BY RANDOM() LIMIT 1")media = c.fetchone()conn.close()return media

2.文件扫描

#scanner.py
import os
import time
import sqlite3
from database import init_db, add_mediadef scan_directory(directory='video'):init_db()print(f"扫描目录: {directory}")for root, dirs, files in os.walk(directory):for file in files:if file.endswith(('.mp4', '.jpg', '.png', '.gif')):path = os.path.join(root, file)print(f"发现文件: {file} 路径: {path}")try:result = add_media(file, path)#print(f"add_media 返回: {result}")  # Debug: Print the return valueif result:print(f"插入 {file} 到数据库")else:print(f"插入 {file} 到数据库失败")except Exception as e:print(f"由于异常无法插入 {file} 到数据库: {str(e)}")def incremental_scan(directory='video'):scanned_files = set()conn = sqlite3.connect('media.db')c = conn.cursor()c.execute("SELECT path FROM media")for row in c.fetchall():scanned_files.add(row[0])conn.close()print("开始增量扫描...")for root, dirs, files in os.walk(directory):for file in files:if file.endswith(('.mp4', '.jpg', '.png', '.gif')):path = os.path.join(root, file)if path not in scanned_files:print(f"发现新文件: {file} 路径: {path}")try:result = add_media(file, path)print(f"add_media 返回: {result}")  # Debug: Print the return valueif result:print(f"插入 {file} 到数据库")else:print(f"插入 {file} 到数据库失败")except Exception as e:print(f"由于异常无法插入 {file} 到数据库: {str(e)}")else:print(f"跳过已存在文件: {file}")if __name__ == '__main__':init_db()while True:incremental_scan()time.sleep(3600)  # 每小时扫描一次

3.web服务

#app.pyfrom flask import Flask, render_template, request, send_file, jsonify, send_from_directory
import os
import sqlite3
import random  # 导入 random 模块
from database import init_db, update_views, update_likes, delete_media, get_random_mediaapp = Flask(__name__)def is_video_file(path):return path.lower().endswith('.mp4')def is_image_file(path):return path.lower().endswith('.jpg') or path.lower().endswith('.jpeg') or path.lower().endswith('.png')def get_random_media():conn = sqlite3.connect('media.db')c = conn.cursor()rand_num = random.random()  # Generate a random number between 0 and 1if rand_num < 0.9:c.execute("SELECT id, name, path FROM media WHERE path LIKE '%.mp4' ORDER BY RANDOM() LIMIT 1;")else:c.execute("SELECT id, name, path FROM media WHERE path LIKE '%.jpg' OR path LIKE '%.jpeg' OR path LIKE '%.png' ORDER BY RANDOM() LIMIT 1;")media = c.fetchone()conn.close()return media@app.route('/')
def index():media = get_random_media()if media:media_id, name, path = mediaupdate_views(media_id)conn = sqlite3.connect('media.db')c = conn.cursor()c.execute("SELECT likes FROM media WHERE id = ?", (media_id,))likes = c.fetchone()[0]conn.close()return render_template('index.html', media_id=media_id, name=name, path=path, likes=likes,is_video=is_video_file(path), is_image=is_image_file(path))return "No media found"@app.route('/media/<path:filename>')
def media(filename):return send_from_directory(directory=os.path.dirname(filename), path=os.path.basename(filename))@app.route('/like/<int:media_id>', methods=['POST'])
def like(media_id):update_likes(media_id)conn = sqlite3.connect('media.db')c = conn.cursor()c.execute("SELECT likes FROM media WHERE id = ?", (media_id,))likes = c.fetchone()[0]conn.close()return jsonify(success=True, likes=likes)@app.route('/delete/<int:media_id>', methods=['POST'])
def delete(media_id):conn = sqlite3.connect('media.db')c = conn.cursor()c.execute("SELECT path FROM media WHERE id = ?", (media_id,))path = c.fetchone()[0]conn.close()if os.path.exists(path):os.remove(path)delete_media(media_id)return jsonify(success=True)@app.route('/download/<int:media_id>')
def download(media_id):conn = sqlite3.connect('media.db')c = conn.cursor()c.execute("SELECT path FROM media WHERE id = ?", (media_id,))path = c.fetchone()[0]conn.close()return send_file(path, as_attachment=True)if __name__ == '__main__':init_db()  # 确保数据库和表被初始化app.run(host='0.0.0.0', port=3000, debug=True)

4.启动器

import os
import threading
import time# 定义运行scanner.py的函数
def run_scanner():# 清空并创建scanner.log文件with open('log/scanner.log', 'wb') as f:passos.system('python scanner.py > log/scanner.log 2>&1')# 定义运行app.py的函数
def run_app():# 清空并创建app.log文件with open('log/app.log', 'wb') as f:passos.system('python app.py > log/app.log 2>&1')if __name__ == '__main__':# 创建log子目录os.makedirs('log', exist_ok=True)# 创建并启动线程运行scanner.pyscanner_thread = threading.Thread(target=run_scanner)scanner_thread.start()# 等待3秒钟time.sleep(3)# 创建并启动线程运行app.pyapp_thread = threading.Thread(target=run_app)app_thread.start()
