- [x] 提供webp生成服务
|
||
- [x] 提供流媒体服务
|
||
- [x] 点击播放之前不加载视频(减少流量消耗)
|
||
- [x] 使用封面图片替代加载视屏第一帧
|
||
- [x] GraphQL 风格API
|
||
- [ ] 列表翻页

GraphQL
|
||
```javascript
|
||
const query = `
|
||
query ($id: Int!) {
|
||
article(id: $id) {
|
||
id
|
||
title
|
||
content
|
||
author {
|
||
id
|
||
name
|
||
}
|
||
}
|
||
}
|
||
`
|
||
|
||
|
||
|
||
|
||
```
|
||
|
||
|
||
通过流媒体服务降低视频文件加载消耗及防止恶意刷流量
|
||
对视频地址添加有效期, 过期需由服务器重新提供token认证观众身份
|
||
可后期增加基于用户账户或cookie信任度评估的视频播放权限认证
|
||
|
||
|
||
```javascript
|
||
// 请求视频播放地址
|
||
import Hls from 'hls.js'
|
||
import axios from 'axios'
|
||
axios.get('/video?url=' + encodeURIComponent(this.src)).then(res => {
|
||
const img = res.data.VideoBase.CoverURL
|
||
if (img) {
|
||
video.poster = img
|
||
}
|
||
const m3u8 = res.data.PlayInfoList.PlayInfo.find(x => x.Format === 'm3u8')
|
||
if (!m3u8) {
|
||
video.src = this.src
|
||
return console.log('流媒体地址不含m3u8')
|
||
}
|
||
this.player = new Hls({ maxMaxBufferLength: 5, autoStartLoad: false })
|
||
this.player.loadSource(m3u8.PlayURL)
|
||
this.player.attachMedia(video)
|
||
this.player.on(Hls.Events.MANIFEST_PARSED, () => {
|
||
if (this.autoplay) {
|
||
video.play()
|
||
}
|
||
})
|
||
}).catch(err => {
|
||
console.log('未取得流媒体地址')
|
||
video.src = this.src
|
||
})
|
||
```
|
||
|
||
|
||
```javascript
|
||
// GET /webp/{type}-{id}-{version}-{width}-{height}-{fit}.{format}
|
||
// @type: image avatar article article_attribute ad
|
||
// @id: int 图片ID或是文章ID或是广告ID
|
||
// @version: update_time 时间戳
|
||
// @width: 宽度 1x 2x 3x 倍图直接输入尺寸
|
||
// @height: 高度 1x 2x 3x 倍图直接输入尺寸
|
||
// @fit: 裁切方式 cover contain fill auto
|
||
|
||
// GET /img/{type}-{id}.{format}?width=320&height=320&fit=cover
|
||
// 更优雅的实现, 使用查询参数的接口 (不幸的是CDN与OSS都不支持)
|
||
|
||
// endpoint: oss-cn-shanghai-internal.aliyuncs.com
|
||
|
||
// 获取查询参数
|
||
let queryParam = "example query";
|
||
|
||
// 安全地编码查询参数
|
||
let safeParam = encodeURIComponent(queryParam);
|
||
|
||
// 创建一个带有安全查询参数的URL
|
||
let url = "http://example.com/tags?param=" + safeParam;
|
||
|
||
// 使用fetch API发送请求
|
||
fetch(url)
|
||
.then(response => response.json())
|
||
.then(data => console.log(data))
|
||
.catch(error => console.error('Error:', error));
|
||
```
|
||
|
||
|
||
## Update
|
||
|
||
```bash
|
||
# 静态编译
|
||
go build bin/main.go
|
||
|
||
# 上传到服务器
|
||
scp ./main root@47.103.40.152:~/main

通用权重模型接口
|
||
|
||
|
||
### 获取图片列表(标准查询)
|
||
|
||
GET /api/images
|
||
```javascript
|
||
{
|
||
page: 1, // 当前页码
|
||
pageSize: 20, // 分页数
|
||
next: true, // 是否存在下一页
|
||
list: [{
|
||
id: 1234, // 原图ID
|
||
width: 512, // 原图宽度
|
||
height: 512, // 原图高度
|
||
user: { // 来源用户
|
||
id: 1234,
|
||
user_name: 'LAST',
|
||
},
|
||
article: { // 来源文章
|
||
id: 1234,
|
||
title: 'GAMEX',
|
||
}
|
||
}]
|
||
}
|
||
```
|
||
|
||
|
||
列表视图:(输出控制)
|
||

|
||
| GET | /api/images?page=1&pageSize=20 | 指定页码和指定分页大小 | ok |
|
||
|
||
|
||
筛选规则:(数据过滤)
|
||
-------------------------------------------------------------------------------------
|
||
| Method | URL | Info | Statu |
|
||
| ------ | ----------------------------- | -------------------------------- | ----- |
|
||
| GET | /api/images?user=1234 | 筛选指定某用户发表的图片 |
|
||
| GET | /api/images?choice=1234 | 筛选指定精选集下的图片 |
|
||
| GET | /api/images?like=1234 | 筛选指定用户点赞的图片 |
|
||
| GET | /api/images?tag=1234 | 筛选含有指定标签的图片 |
|
||
| GET | /api/images?tag=1234,1235 | 筛选含有多个标签之一的图片(并集) |
|
||
| GET | /api/images?tag=1234&tag=1235 | 筛选含有指定多个标签的图片(交集) |
|
||
| GET | /api/images?user=1234&tag=123 | 筛选指定用户的指定标签图片(交集) |
|
||
| GET | /api/images?date=20220214+ | 时间范围(之后) |
|
||
| GET | /api/images?date=20220214- | 时间范围(之前) |
|
||
| GET | /api/images?date=2022~2023 | 时间范围(之间) |
|
||
|
||
|
||
排序规则:(权重强化)
|
||
-------------------------------------------------------------------------------------
|
||
| Method | URL | Info | Status |
|
||
| ------ | ------------------------ | --------------------------------------- | ------ |
|
||
| GET | /api/images?similar=1234 | 根据指定图片的相似图片(指定图片ID) | ok |
|
||
| GET | /api/images?sort=date+ | 排序规则(相似图片查询时此项无效) |
|
||
| GET | /api/images?sort=like | 根据用户偏好推荐(指定用户的偏好) |

|
||
* 权重强化属于排序规则而非过滤规则
|
||
|
||
|
||
### 獲取任務列表(標準查询)
|
||
|
||
GET /api/tasks
|
||
```javascript
|

next: true, // 是否存在下一页
|
||
list: [{
|
||
id: 'xxxxxx', // 任務ID
|
||
type: '', // 任務類型(推理, 訓練)
|
||
data: {}, // 任務執行數據
|
||
create_time: '' // 任務創建時間
|
||
update_time: '' // 任務更新時間
|
||
}],
|
||
}
|
||
```
|
||
|
||
Websocket /api/tasks/{task_id}
|
||
```javascript
|
||
{
|
||
// 狀態
|
||
// 進度
|
||
// 結果
|
||
}
