# 阿里云 OSS 文件上传
这个技能提供阿里云 OSS(对象存储服务)的文件上传功能,支持生成带签名的临时访问链接。
## 快速开始
### 1. 配置环境变量
使用前必须配置以下环境变量(详见 [references/config.md](references/config.md)):
```bash
export ALIYUN_OSS_ACCESS_KEY_ID="your-access-key-id"
export ALIYUN_OSS_ACCESS_KEY_SECRET="your-access-key-secret"
export ALIYUN_OSS_ENDPOINT="https://oss-cn-hangzhou.aliyuncs.com"
export ALIYUN_OSS_BUCKET="your-bucket-name"
```
### 2. 安装依赖
```bash
pip install oss2
```
## 使用方法
### 上传文件
```bash
python scripts/oss-upload.py upload --file /path/to/local/file.txt
```
可选参数:
- `--key`:指定 OSS 中的文件名(默认使用本地文件名)
- `--expire`:链接有效期(秒,默认 3600)
示例:
```bash
# 上传到指定路径
python scripts/oss-upload.py upload --file photo.jpg --key images/photo.jpg --expire 7200
```
### 生成临时访问链接
```bash
python scripts/oss-upload.py url --key images/photo.jpg --expire 3600
```
## 工作流程
1. 用户请求上传文件时:
- 确认本地文件路径
- 运行上传脚本
- 返回上传结果和临时访问链接
2. 用户已有 OSS 文件需要访问链接时:
- 运行 url 命令生成签名链接
- 返回临时访问 URL
## 注意事项
- 临时链接有效期默认 1 小时,可根据需求调整
- Bucket 建议设置为私有,通过签名链接安全访问
- 上传大文件时脚本会自动处理,无需额外配置
