これは **FastAPI** が以下のようなボディを期待することを意味します:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {
        "url": "http://example.com/baz.jpg",
        "name": "The Foo live"
    }
}
```

繰り返しになりますが、**FastAPI** を使用して、その宣言を行うだけで以下のような恩恵を受けられます:

{
    "name": "s3-zip-example",
    "version": "1.0.0",
    "main": "main.js",
    "dependencies": {
        "aws-sdk": "^2.924.0"
    }

			"SELECT * FROM `users` FOR UPDATE", nil,

			[]clause.Interface{clause.Select{}, clause.From{}, clause.Locking{Strength: clause.LockingStrengthShare, Table: clause.Table{Name: clause.CurrentTable}}},
			"SELECT * FROM `users` FOR SHARE OF `users`", nil,
		},
