she felt a violent blow underneath her chin:  it had struck her
foot!

  She was a good deal frightened by this very sudden change, but
she felt that there was no time to be lost, as she was shrinking
rapidly; so she set to work at once to eat some of the other bit.
Her chin was pressed so closely against her foot, that there was
hardly room to open her mouth; but she did it at last, and

回到前面的代码示例，**FastAPI** 将会：

* 校验 `GET` 和 `PUT` 请求的路径中是否含有 `item_id`。
* 校验 `GET` 和 `PUT` 请求中的 `item_id` 是否为 `int` 类型。
    * 如果不是，客户端将会收到清晰有用的错误信息。
* 检查 `GET` 请求中是否有命名为 `q` 的可选查询参数（比如 `http://127.0.0.1:8000/items/foo?q=somequery`）。
    * 因为 `q` 被声明为 `= None`，所以它是可选的。
    * 如果没有 `None` 它将会是必需的 (如 `PUT` 例子中的请求体)。
* 对于访问 `/items/{item_id}` 的 `PUT` 请求，将请求体读取为 JSON 并：
    * 检查是否有必需属性 `name` 并且值为 `str` 类型 。

Ve uzun süre kuyrukta beklemek 🕙 zorundasın yoksa sıranı kaybedersin.

Muhtemelen ayak işlerı yaparken sevgilini 😍 bankaya 🏦 getirmezsin.

### Burger Sonucu

Bu "aşkınla fast food burgerleri" senaryosunda, çok fazla bekleme olduğu için 🕙, eşzamanlı bir sisteme sahip olmak çok daha mantıklı ⏸🔀⏯.

Web uygulamalarının çoğu için durum böyledir.
