      // If the path is absent or didn't start with '/', use the default path. It's a string like

이는 **FastAPI**가 다음과 유사한 본문을 기대한다는 것을 의미합니다:

```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"
    }
}
```

다시 한번, **FastAPI**를 사용하여 해당 선언을 함으로써 얻는 것은:

* 중첩 모델도 편집기 지원(자동완성 등)
* 데이터 변환

    val name = truncateName(subprojects.joinToString(","))

    private fun truncateName(str: String) =
        // Can't exceed Linux file name limit 255 char on TeamCity
        if (str.length > 200) {
            str.substring(0, 200) + "..."
        } else {
            str
        }

 *
 * Each line of the `urltestdata.txt` file specifies a test. Lines look like this:
 *
 * ```
 * http://example\t.\norg http://example.org/foo/bar s:http h:example.org p:/
 * ```

class WebPlatformUrlTestData {
  var input: String? = null
  var base: String? = null
  var scheme = ""
  var username = ""
  var password: String? = null
  var host = ""

```
{
  "item": "The Foo Wrestlers"
}
```

Mas se o cliente faz uma requisição para `http://example.com/items/bar` (ou seja, um não existente `item_id "bar"`), esse cliente receberá um HTTP status code 404 (o erro "não encontrado" — *not found error*), e uma resposta JSON:

```JSON
{
  "detail": "Item not found"
}
```

!!! tip "Dica"

      pos: Int,
      limit: Int,
    ): Int {
      if (limit - pos < 2) return -1

      val c0 = input[pos]
      if ((c0 < 'a' || c0 > 'z') && (c0 < 'A' || c0 > 'Z')) return -1 // Not a scheme start char.

      characters@ for (i in pos + 1 until limit) {
        return when (input[i]) {
          // Scheme character. Keep going.
          in 'a'..'z', in 'A'..'Z', in '0'..'9', '+', '-', '.' -> continue@characters

This would mean that **FastAPI** would expect a body similar to:

```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"
    }
}
```

Again, doing just that declaration, with **FastAPI** you get:

Then, with a URL like:

```
http://localhost:8000/items/?q=foo&q=bar
```

you would receive the multiple `q` *query parameters'* values (`foo` and `bar`) in a Python `list` inside your *path operation function*, in the *function parameter* `q`.

So, the response to that URL would be:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```
