ContentAutomationHub 的系统的核心模块和数据流:

 ContentAutomationHub flow

二、环境配置与项目初始化

在您的Ubuntu服务器上执行以下命令:

  1. 安装系统依赖

sudo apt update
sudo apt install python3-pip python3-venv redis-server -y
sudo systemctl start redis && sudo systemctl enable redis

  1. 创建项目目录并初始化虚拟环境

      mkdir ~/ContentAutomationHub && cd ~/ContentAutomationHub

      python3 -m venv venv

      source venv/bin/activate

  1. 安装核心Python库

        pip install flask celery redis requests sqlalchemy pymysql flask-cors

        # 用于未来可能的API管理

        pip install flask-restx

三、数据库设计 (MySQL 8)

     在MySQL中创建数据库 content_hub,然后执行以下SQL创建核心表:

      

-- 任务主表
CREATE TABLE task (
id INT PRIMARY KEY AUTO_INCREMENT,
title VARCHAR(255) NOT NULL COMMENT '选题标题',
keywords TEXT COMMENT '关键词',
status ENUM('pending', 'generating', 'review', 'publishing', 'published', 'failed') DEFAULT 'pending',
ai_raw_content LONGTEXT COMMENT 'AI生成的原始内容',
final_content LONGTEXT COMMENT '审核后的最终内容',
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
);

-- 发布平台配置表(安全存储各平台密钥)
CREATE TABLE publish_platform (
id INT PRIMARY KEY AUTO_INCREMENT,
name VARCHAR(50) NOT NULL COMMENT '如:joomla, wechat',
config JSON COMMENT '存储API URL、密钥等JSON化配置',
is_active BOOLEAN DEFAULT TRUE
);

-- 发布日志表
CREATE TABLE publish_log (
id INT PRIMARY KEY AUTO_INCREMENT,
task_id INT,
platform_id INT,
status ENUM('success', 'failed'),
response TEXT COMMENT '平台返回的原始响应',
published_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
FOREIGN KEY (task_id) REFERENCES task(id),
FOREIGN KEY (platform_id) REFERENCES publish_platform(id)
);

 

四、核心模块代码实现

现在,开始创建最关键的几个Python模块。

1. 应用工厂与Celery配置 (app.py)
这是应用的启动核心,它初始化Flask和Celery。

# app.py
from flask import Flask
from celery import Celery
import os

# 初始化Celery
celery = Celery(
'tasks',
broker='redis://localhost:6379/0',
backend='redis://localhost:6379/0'
)

def create_app():
app = Flask(__name__)
app.config['SECRET_KEY'] = os.environ.get('SECRET_KEY', 'your-secret-key-here')

# 将Celery与App关联
celery.conf.update(app.config)

# 注册蓝图(后续定义)
from routes import main_bp
app.register_blueprint(main_bp)

return app

# 创建应用实例
app = create_app()

 

2. 核心任务定义 (tasks.py)
这里定义了需要Celery在后台执行的异步任务,特别是调用AI和发布。

# tasks.py
from app import celery
import requests
import json
from models import Task, db # 假设您用Flask-SQLAlchemy定义了模型

DEEPSEEK_API_URL = "https://api.deepseek.com/v1/chat/completions"
DEEPSEEK_API_KEY = "your-deepseek-api-key" # 务必从环境变量读取!

@celery.task(bind=True)
def generate_article(self, task_id):
"""任务1:调用DeepSeek生成文章"""
task = Task.query.get(task_id)
if not task:
return

task.status = 'generating'
db.session.commit()

headers = {
'Authorization': f'Bearer {DEEPSEEK_API_KEY}',
'Content-Type': 'application/json'
}
# 精心设计的提示词,是生成高质量文章的关键
prompt = f"你是一位资深的电子通信技术专家。请以'{task.title}'为题,撰写一篇深入的技术文章。要求:专业严谨、逻辑清晰、包含实例,字数在1500字左右。关键词:{task.keywords}"

payload = {
"model": "deepseek-chat",
"messages": [{"role": "user", "content": prompt}],
"temperature": 0.7
}

try:
response = requests.post(DEEPSEEK_API_URL, headers=headers, json=payload, timeout=60)
result = response.json()
article_content = result['choices'][0]['message']['content']

task.ai_raw_content = article_content
task.status = 'review' # 更新状态为待审核
db.session.commit()
return {"success": True, "task_id": task_id}
except Exception as e:
task.status = 'failed'
db.session.commit()
return {"success": False, "error": str(e)}

@celery.task(bind=True)
def publish_article(self, task_id, platform_list):
"""任务2:将审核后的文章发布到多个平台"""
task = Task.query.get(task_id)
if task.status != 'review':
return

task.status = 'publishing'
db.session.commit()

publish_results = []
for platform_name in platform_list:
# 这里将调用您为每个平台编写的适配器
result = dispatch_to_platform(platform_name, task.final_content, task.title)
publish_results.append(result)

# 记录日志到 publish_log 表(略)
task.status = 'published'
db.session.commit()
return publish_results

def dispatch_to_platform(platform_name, content, title):
# 这里是一个分发器的示例,您需要为每个平台实现具体函数
platforms = {
'joomla': publish_to_joomla,
'wechat': publish_to_wechat, # 微信公众号
# ... 其他平台
}
func = platforms.get(platform_name)
return func(content, title) if func else {"status": "failed", "error": "Unknown platform"}

 

3. Web路由与界面 (routes.py)
提供简单的Web界面供用户提交选题和审核。

# routes.py
from flask import Blueprint, render_template, request, jsonify, redirect, url_for
from models import Task, db
from tasks import generate_article, publish_article

main_bp = Blueprint('main', __name__)

@main_bp.route('/')
def index():
tasks = Task.query.order_by(Task.created_at.desc()).limit(10).all()
return render_template('index.html', tasks=tasks) # 需要创建简单的前端模板

@main_bp.route('/submit_task', methods=['POST'])
def submit_task():
title = request.form.get('title')
keywords = request.form.get('keywords')

new_task = Task(title=title, keywords=keywords, status='pending')
db.session.add(new_task)
db.session.commit()

# 异步调用AI生成任务
generate_article.delay(new_task.id)

return redirect(url_for('main.index'))

@main_bp.route('/approve_and_publish/<int:task_id>', methods=['POST'])
def approve_and_publish(task_id):
task = Task.query.get(task_id)
if task and task.status == 'review':
# 假设前端通过表单传递了最终修改的内容
task.final_content = request.form.get('final_content', task.ai_raw_content)
# 选择要发布的平台,例如: ['joomla', 'weibo']
platforms_to_publish = request.form.getlist('platforms')

# 异步调用发布任务
publish_article.delay(task_id, platforms_to_publish)

return jsonify({"status": "success", "message": "发布任务已启动"})
return jsonify({"status": "error", "message": "任务状态不允许发布"}), 400

4. 平台发布适配器示例 (platforms/joomla_publisher.py)
每个平台都需要一个这样的适配器。以Joomla为例(假设已安装API插件):

# platforms/joomla_publisher.py
import requests
import json

def publish_to_joomla(content, title, category_id=1):
"""
发布到Joomla
假设您的Joomla已安装并配置了API插件,提供了/articles端点
"""
joomla_config = {
'api_url': 'https://bluetooth.com.cn/api/index.php/v1/articles',
'api_key': 'your-joomla-api-token'
}

headers = {
'X-API-KEY': joomla_config['api_key'],
'Content-Type': 'application/json'
}

article_data = {
'title': title,
'alias': title.replace(' ', '-').lower(),
'articletext': content,
'state': 1, # 1表示发布,0表示未发布
'catid': category_id,
'language': '*'
}

try:
response = requests.post(
joomla_config['api_url'],
headers=headers,
data=json.dumps(article_data),
timeout=30
)
if response.status_code in [200, 201]:
return {"platform": "joomla", "status": "success", "article_id": response.json().get('id')}
else:
return {"platform": "joomla", "status": "failed", "error": response.text}
except Exception as e:
return {"platform": "joomla", "status": "failed", "error": str(e)}

 

五、启动与部署
启动Redis服务:sudo systemctl start redis

启动Celery Worker(在项目目录下):

bash
celery -A tasks.celery worker --loglevel=info --pool=solo
启动Flask开发服务器:

bash
export FLASK_APP=app.py
flask run --host=0.0.0.0 --port=5000
访问应用:打开浏览器,访问 http://你的服务器IP:5000。

六、后续开发与关键建议
分阶段实施(至关重要!):

阶段一:只实现 Flask + Celery + DeepSeek API,完成“提交-生成-查看”闭环。

阶段二:实现 Joomla发布,这是您最核心的需求。

阶段三:逐个接入其他平台,每个平台的API集成都可能需要1-2天的专门研究。

安全加固:

所有API密钥(DeepSeek、各平台)务必通过环境变量读取,绝不能硬编码在代码中。

考虑为Flask应用添加用户认证(如使用Flask-Login)。

生产环境部署:

使用 Gunicorn 或 uWSGI 替代Flask开发服务器。

使用 Supervisor 或 Systemd 管理Celery Worker和Web进程,保证稳定性。

配置Nginx作为反向代理,处理HTTPS。

扩展性考虑:

在tasks.py中,可以为不同平台设置不同的任务队列(如queue='wechat'),实现优先级处理。

添加更完善的任务状态查询和重试机制。

您已经拥有了一个功能完整、架构清晰的蓝图。请立即从“阶段一”开始,先让Flask和Celery跑起来,成功调用一次DeepSeek API。
