# Does it send mock mail? (true: no send actually, logging only)
mail.send.mock = true

# SMTP server settings for main: host:port
mail.smtp.server.main.host.and.port = localhost:25

```python

```

Si tu código estuviera estructurado así:

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

Entonces pondrías el `entrypoint` como:

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

lo cual sería equivalente a:

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

```python
from main import app
```

Si votre code est structuré comme :

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

Alors vous définiriez le `entrypoint` comme :

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

ce qui équivaudrait à :

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

```python
from main import app
```

Se o seu código estiver estruturado assim:

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

Então você definiria o `entrypoint` como:

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

o que seria equivalente a:

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

注意，现在我们不再创建默认实例 `settings = Settings()`。

### 主应用文件 { #the-main-app-file }

现在我们创建一个依赖项，返回一个新的 `config.Settings()`。

{* ../../docs_src/settings/app02_an_py310/main.py hl[6,12:13] *}

/// tip | 提示

我们稍后会讨论 `@lru_cache`。

目前你可以把 `get_settings()` 当作普通函数。

///

然后我们可以在路径操作函数中将其作为依赖项引入，并在需要的任何地方使用它。

{* ../../docs_src/settings/app02_an_py310/main.py hl[17,19:21] *}

Kodunuz şöyle yapılandırılmışsa:

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

O zaman `entrypoint`'i şöyle ayarlardınız:

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

Bu da şuna eşdeğer olur:

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