|
|
```
|
|
|
|
- 获取所有书籍：
|
|
```sh
|
|
curl http://localhost:8080/api/books
|
|
```
|
|
|
|
|
|
- 根据 ID 获取书籍：
|
|
```sh
|
|
curl http://localhost:8080/api/books/1
|
|
```
|
|
|
|
- 更新书籍：
|
|
```sh
|
|
curl -X PUT http://localhost:8080/api/books/1 -H "Content-Type: application/json" -d '{"title": "Go 语言进阶", "author": "张三", "price": 49.99}'
