||||||
|
|
||||||
|
### 获取图像文件
|
||||||
|
```
|
||||||
|
GET /api/v1/photo/{hash}
|
||||||
|
```
|
||||||
|
|
||||||
|
#### 查询参数
|
||||||
|
- `format`: 图像格式 (可选)
|
||||||
|
- `original`: 原图 (默认)
|
||||||
|
- `thumbnail`: 缩略图
|
||||||
|
- `size`: 缩略图尺寸 (可选，仅在format=thumbnail时有效)
|
||||||
|
- 格式: `WIDTHxHEIGHT` (例如: `400x400`)
|
||||||
|

## 🎯 缩略图生成逻辑
|
||||||
|
|
||||||
|
### 尺寸限制
|
||||||
|
- `size` 参数指定的是**最大尺寸限制**，不是精确尺寸
|
||||||
|
- 系统会按原图比例缩放，确保图像不超过指定的宽度和高度
|
||||||
|
- 例如: `size=400x400` 对于 1920x1080 的图像，会生成 400x225 的缩略图
|
||||||
|
|
||||||
|
### 缓存机制
|
||||||
|
- 缩略图会被缓存到 `{AppDir}/cache/thumbnail/` 目录
|
||||||
|
- 文件名格式: `{hash}_{width}x{height}.jpg`
|
||||||
|
- 如果缩略图已存在，直接返回缓存文件
|
||||||
|
|
||||||
|
### 默认尺寸
|
||||||
|
- 如果未指定 `size` 参数，使用配置文件中的 `defaultThumbnailSize`
|
||||||
|
- 默认值: 720像素
|
||||||
|
|
||||||
|
## 🚀 快速开始
|
||||||
|
|
||||||
|
1. **启动服务器**
|
||||||
|
```bash
|
||||||
|
go run .
|
||||||
|
```
|
||||||
|
|
||||||
|
2. **添加图像库**
|
||||||
|
```bash
|
||||||
|
curl -X POST "http://localhost:8080/api/v1/library" \
|
||||||
|
-H "Content-Type: application/json" \
|
||||||
|
-d '{"path": "/path/to/your/photos"}'
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **开始索引**
|
||||||
|
```bash
|
||||||
|
curl -X POST "http://localhost:8080/api/v1/library/indexed"
|
||||||
|
```
|
||||||
|
|
||||||
|
4. **获取图像列表**
|
||||||
|
```bash
|
||||||
|
curl "http://localhost:8080/api/v1/library"
|
||||||
|
```
|
||||||
|
|
||||||
|
5. **使用图像hash测试接口**
|
||||||
|
```bash
|
||||||
|
# 使用实际的hash值
|
||||||
|
curl "http://localhost:8080/api/v1/assets/{actual_hash}"
|
||||||
|
curl "http://localhost:8080/api/v1/photo/{actual_hash}?format=thumbnail&size=400x400"
|
||||||
|
```
|
||||||
|
|
||||||
|
## ⚠️ 注意事项
|
||||||
|
|
||||||
|
- hash参数是必需的，必须是有效的图像hash值
|
||||||
|
- 图像文件必须存在且可访问
|
||||||
|
- 缩略图生成可能需要一些时间，特别是对于大图像
|
||||||
|
- API会自动更新图像的访问计数和访问时间
|
||||||
|
- 所有时间字段都以ISO 8601格式返回
|
||||||
|
|
||||||
|
## 📝 错误代码
|
||||||
|
|
||||||
|
- `400 Bad Request`: 参数错误（如size格式错误）
|
||||||
|
- `404 Not Found`: 图像不存在或文件不可访问
|
||||||
|
- `500 Internal Server Error`: 服务器内部错误（如缩略图生成失败）

|
||||||
|
|
||||||
|
### ===== 使用说明 =====
|
||||||
|
###
|
||||||
|
### 1. 启动服务器：
|
||||||
|
### go run .
|
||||||
|
###
|
||||||
|
### 2. 修改变量：
|
||||||
|
### - 将 sample_hash_12345 替换为实际的图像hash
|
||||||
|
### - 将 D:/Pictures 替换为实际的图像目录路径
|
||||||
|
###
|
||||||
|
### 3. 执行测试：
|
||||||
|
### - 先执行基础功能测试（健康检查、添加图像库、索引）
|
||||||
|
### - 从索引结果中获取实际的hash值
|
||||||
|
### - 使用实际hash测试图像接口
|
||||||
|
###
|
||||||
|
### 4. 查看响应：
|
||||||
|
### - 图像文件接口会返回二进制图像数据
|
||||||
|
### - 详情接口会返回JSON格式的完整信息
|
||||||
|
### - 错误情况会返回包含错误信息的JSON
|
||||||
|
###
|
||||||
|
### 5. 注意事项：
|
||||||
|
### - 确保图像文件存在且可访问
|
||||||
|
### - 缩略图生成可能需要一些时间
|
||||||
|
### - 大图像的缩略图生成会比较慢
