|
||
```
|
||
|
||
## 小程序使用建议
|
||
|
||
### 1. 分页加载
|
||
推荐使用分页加载，避免一次性加载过多数据：
|
||
```javascript
|
||
// 小程序端示例
|
||
wx.request({
|
||
url: 'http://localhost:5000/api/rank/videos',
|
||
data: {
|
||
page: 1,
|
||
limit: 20,
|
||
sort: 'playcount'
|
||
},
|
||
success: (res) => {
|
||
if (res.data.success) {
|
||
this.setData({
|
||
videos: res.data.data,
|
||
hasNext: res.data.pagination.has_next
|
||
})
|
||
}
|
||
}
|
||
})
|
||
```
|
||
|
||
### 2. 搜索优化
|
||
- 使用防抖处理搜索请求
|
||
- 显示搜索进度和结果数量
|
||
- 提供搜索建议
|
||
|
||
### 3. 图片加载
|
||
- 使用 `cover_image_url` 作为封面图片
|
||
- 添加图片加载失败处理
|
||
|
||
### 4. 数据更新
|
||
- 注意 `update_time` 字段，判断数据新鲜度
|
||
- 合理使用缓存策略
|
||
- 定期检查服务健康状态
|
||
|
||
### 5. 文章管理
|
||
推荐的文章列表加载方式：
|
||
```javascript
|
||
// 小程序端示例 - 文章列表
|
||
wx.request({
|
||
url: 'http://localhost:5001/api/article/list',
|
||
data: {
|
||
page: 1,
|
||
limit: 10,
|
||
sort: 'created_at',
|
||
order: 'desc'
|
||
},
|
||
success: (res) => {
|
||
if (res.data.success) {
|
||
this.setData({
|
||
articles: res.data.data,
|
||
hasNext: res.data.pagination.has_next
|
||
})
|
||
}
|
||
}
|
||
})
|
||
```
|
||
|
||
文章搜索示例：
|
||
```javascript
|
||
// 小程序端示例 - 文章搜索
|
||
wx.request({
|
||
url: 'http://localhost:5001/api/article/search',
|
||
data: {
|
||
q: 'AI',
|
||
page: 1,
|
||
limit: 5
|
||
},
|
||
success: (res) => {
|
||
if (res.data.success) {
|
||
this.setData({
|
||
searchResults: res.data.data
|
||
})
|
||
}
|
||
}
|
||
})
|
||
```
|
||
|
||
## 部署说明
|
||
|
||
### 启动服务
|
||
```bash
|
||
cd /Users/binghuixiong/剧变AI/rank_backend
|
||
python3 app.py
|
||
```
|
||
|
||
### 服务信息
|
||
- 端口：5001
|
||
- 数据库：MongoDB (localhost:27017)
|
||
- 数据库名：kemeng_media
|
||
- 数据更新：每晚24:00自动执行
|
||
|
||
### 注意事项
|
||
- 确保MongoDB服务已启动
|
||
- 确保网络连接正常
|
||
- 小程序端需要配置合法域名（生产环境）
