[`jstmpllitinterp` setting](/pkg/html/template#hdr-Security_Model).
This behavior was backported to Go 1.19.8+ and Go 1.20.3+.

Go 1.21 introduced a limit on the maximum number of MIME headers and multipart
forms, controlled by the
[`multipartmaxheaders` and `multipartmaxparts` settings](/pkg/mime/multipart#hdr-Limits)
respectively.
This behavior was backported to Go 1.19.8+ and Go 1.20.3+.

El query es el conjunto de pares de key-value que van después del `?` en la URL, separados por caracteres `&`.

Por ejemplo, en la URL:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

...los parámetros de query son:

* `skip`: con un valor de `0`
* `limit`: con un valor de `10`

Dado que son parte de la URL son strings "naturalmente".

```

A consulta é o conjunto de pares chave-valor que vai depois de `?` na URL, separado pelo caractere `&`.

Por exemplo, na URL:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

...os parâmetros da consulta são:

* `skip`: com o valor `0`
* `limit`: com o valor `10`

Como eles são parte da URL, eles são "naturalmente" strings.

## 默认值

查询参数不是路径的固定内容，它是可选的，还支持默认值。

上例用 `skip=0` 和 `limit=10` 设定默认值。

访问 URL：

```
http://127.0.0.1:8000/items/
```

与访问以下地址相同：

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

但如果访问：

```
http://127.0.0.1:8000/items/?skip=20
```

查询参数的值就是：

* `skip=20`：在 URL 中设定的值
* `limit=10`：使用默认值

## 可选参数

同理，把默认值设为 `None` 即可声明**可选的**查询参数：

        self.q = q
        self.skip = skip
        self.limit = limit


@app.get("/items/")
async def read_items(commons: CommonQueryParams = Depends(CommonQueryParams)):
    response = {}
    if commons.q:
        response.update({"q": commons.q})
    items = fake_items_db[commons.skip : commons.skip + commons.limit]
    response.update({"items": items})
