## Declaring types { #declaring-types }

You just saw the main place to declare type hints. As function parameters.

This is also the main place you would use them with **FastAPI**.

### Simple types { #simple-types }

You can declare all the standard Python types, not only `str`.

You can use, for example:

* [`Parameter Object` (명세서에 있는)](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#parameter-object)는 FastAPI의 다음 기능에서 쓰였습니다:
    * `Path()`
    * `Query()`
    * `Header()`
    * `Cookie()`
* [`Request Body Object`, `Media Type Object` (명세서에 있는)의 `content` 필드에 있는](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#media-type-object)는 FastAPI의 다음 기능에서 쓰였습니다:
    * `Body()`
    * `File()`

import (
	"bytes"
	"crypto"
	"crypto/hmac"
	"encoding/base64"
	"errors"
	"fmt"
	"hash"
	"time"

	"github.com/buger/jsonparser"

        findLatest("slf4j", "org.slf4j:slf4j-api:[2.0.17,)", versionProperties)

        // Starting with ScalaTest 3.1.0, the third party integration were moved out of the main JAR
        findLatest("scalatest", "org.scalatest:scalatest_${versionProperties["scala"]}:[3.1,)", versionProperties)

<div class="termy">

```console
$ cd ~/code/prisoner-of-azkaban

$ python main.py

// Error importando sirius, no está instalado 😱
Traceback (most recent call last):
    File "main.py", line 1, in <module>
        import sirius
```

</div>

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

**Note**: 请确保把 `"fastapi[standard]"` 用引号包起来，以保证在所有终端中都能正常工作。

## 示例 { #example }

### 创建 { #create-it }

创建文件 `main.py`，内容如下：

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")

**Hinweis**: Stellen Sie sicher, dass Sie `"fastapi[standard]"` in Anführungszeichen setzen, damit es in allen Terminals funktioniert.

## Beispiel { #example }

### Erstellung { #create-it }

Erstellen Sie eine Datei `main.py` mit:

```Python
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
def read_root():
    return {"Hello": "World"}


@app.get("/items/{item_id}")

### `root_path` 제공하기 { #providing-the-root-path }

이를 달성하려면 다음처럼 커맨드 라인 옵션 `--root-path`를 사용할 수 있습니다:

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

* [`Parameter Object`（仕様内）](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#parameter-object)。FastAPIの以下で使用されました:
    * `Path()`
    * `Query()`
    * `Header()`
    * `Cookie()`
* [`Request Body Object`、`Media Type Object`の`content`フィールド（仕様内）](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#media-type-object)。FastAPIの以下で使用されました:
    * `Body()`
    * `File()`
