在一个 **Pydantic 模型**中声明你需要的**查询参数**，然后将参数声明为 `Query`：

{* ../../docs_src/query_param_models/tutorial001_an_py310.py hl[9:13,17] *}

**FastAPI** 将会从请求的**查询参数**中**提取**出**每个字段**的数据，并将其提供给你定义的 Pydantic 模型。

## 查看文档 { #check-the-docs }

你可以在 `/docs` 页面的 UI 中查看查询参数：

<div class="screenshot">
<img src="/img/tutorial/query-param-models/image01.png">
</div>

## 禁止额外的查询参数 { #forbid-extra-query-parameters }

		errCode := toAPIErrorCode(ctx, testCase.err)
		if errCode != testCase.errCode {
			t.Errorf("Test %d: Expected error code %d, got %d", i+1, testCase.errCode, errCode)
		}
	}
}

// Check if an API error is properly defined
func TestAPIErrCodeDefinition(t *testing.T) {
	for errAPI := ErrNone + 1; errAPI < apiErrCodeEnd; errAPI++ {
		errCode, ok := errorCodes[errAPI]
		if !ok {

// has reached zero, i.e when all the readers have given up their locks.
type RLockedFile struct {
	*LockedFile
	mutex sync.Mutex
	refs  int // Holds read lock refs.
}

// IsClosed - Check if the rlocked file is already closed.
func (r *RLockedFile) IsClosed() bool {
	r.mutex.Lock()
	defer r.mutex.Unlock()
	return r.refs == 0
}

// IncLockRef - is used by called to indicate lock refs.

Isto porque espera-se que os **seus usuários** definam o verdadeiro **URL path** onde eles desejam receber a requisição do webhook de algum outra maneira. (e.g. um painel).

### Confira a documentação { #check-the-docs }

Agora você pode iniciar a sua aplicação e ir até [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

O **FastAPI** irá **extrair** os dados para **cada campo** dos **cookies** recebidos na requisição e lhe fornecer o modelo Pydantic que você definiu.

## Verifique a Documentação { #check-the-docs }

Você pode ver os cookies definidos na IU da documentação em `/docs`:

### 覆寫方法 { #override-the-method }

現在你可以用新的函式取代 `.openapi()` 方法。

{* ../../docs_src/extending_openapi/tutorial001_py310.py hl[29] *}

### 檢查看看 { #check-it }

造訪 [http://127.0.0.1:8000/redoc](http://127.0.0.1:8000/redoc) 後，你會看到自訂的 logo（此例為 **FastAPI** 的 logo）：

/// info | Дополнительная информация

Помните, что `response_description` относится конкретно к ответу, а `description` относится к *операции пути* в целом.

///

/// check | Проверка

OpenAPI указывает, что каждой *операции пути* необходимо описание ответа.

Если вдруг вы не укажете его, то **FastAPI** автоматически сгенерирует это описание с текстом "Successful response".
