# 七牛(Kodo)直传:获取上传凭证
用途:小程序/前端把文件直接上传到七牛(CDN 源站),后端只负责签发上传 token,减少带宽与压力。
## 前置条件
- 已完成登录并拿到 `session_key`(见:`docs/common/auth.md`
- 已配置 `.env` 中的七牛参数(见:`.env.example`
## 接口
`POST /api/v1/common/upload/qiniu/token`
Header
```
Authorization: Bearer <session_key>
Content-Type: application/json
```
请求体(可选):
```json
{
"filename": "avatar.png"
}
```
说明:
- `filename` 仅用于提取文件后缀(例如 `.png`),以便后端生成带后缀的 `key`;不传也可以。
成功响应示例:
```json
{
"code": 200,
"message": "success",
"data": {
"token": "xxx",
"key": "uploads/mp_1/user_123/20251231/ab12cd34ef....png",
"upload_url": "https://upload.qiniup.com",
"expire": 1767150000,
"cdn_domain": "https://cdn.example.com"
}
}
```
字段说明:
- `token`:七牛上传凭证(uptoken
- `key`:后端生成的对象 key,上传时必须使用该 key
- `upload_url`:上传入口(表单上传 URL
- `expire`token 过期时间(Unix 秒)
- `cdn_domain`:可选;如果配置了,可用 `cdn_domain + "/" + key` 拼出访问 URL
## 使用示例(curl 直传)
1) 先请求 token
```bash
curl -X POST 'http://127.0.0.1:8080/api/v1/common/upload/qiniu/token' \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer wx-session-key' \
-d '{"filename":"avatar.png"}'
```
2) 再把文件直传七牛(multipart/form-data):
```bash
curl -X POST 'https://upload.qiniup.com' \
-F "token=上一步返回的 token" \
-F "key=上一步返回的 key" \
-F "file=@./avatar.png"
```
七牛成功时会返回 JSON(字段可能因配置不同略有差异),其中一般会包含 `key/hash`
