```python
from main import app
```

もしコード構成が次のようになっている場合:

```
.
├── backend
│   ├── main.py
│   ├── __init__.py
```

このときは`entrypoint`を次のように設定します:

```toml
[tool.fastapi]
entrypoint = "backend.main:app"
```

これは次と同等です:

```python
from backend.main import app
```

### 메인 앱 파일 { #the-main-app-file }

이제 새로운 `config.Settings()`를 반환하는 의존성을 생성합니다.

/// tip | 팁

`@lru_cache`는 조금 뒤에 다룹니다.

지금은 `get_settings()`가 일반 함수라고 가정해도 됩니다.

///

그 다음 *경로 처리 함수*에서 이를 의존성으로 요구하고, 필요한 어디서든 사용할 수 있습니다.

## 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:

// additional allocation tweaks reproduced using GODEBUG=allocfreetrace=1
// original file https://github.com/golang-jwt/jwt/blob/main/parser.go
// borrowed under MIT License https://github.com/golang-jwt/jwt/blob/main/LICENSE

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

	"github.com/buger/jsonparser"

- [`Parameter Object`（规范中）](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#parameter-object)，被 FastAPI 的以下内容使用：
    - `Path()`
    - `Query()`
    - `Header()`
    - `Cookie()`
- [`Request Body Object` 中的 `content` 字段里的 `Media Type Object`（规范中）](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#media-type-object)，被 FastAPI 的以下内容使用：
    - `Body()`
    - `File()`

* [`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()`

4.  Do your best to have a [well-formed commit message][] for the change.
5.  Pull requests typically do not need to modify the files under the `android`
    directory: We have a script that automatically mirrors changes from the main
    directories into the `android` directories.
