提供webp生成服务
|
||
|
||
```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)
|
||
```
|
||
|

|
||
## 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

||
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
