```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
```

## Path parameters containing paths

Let's say you have a *path operation* with a path `/files/{file_path}`.

But you need `file_path` itself to contain a *path*, like `home/johndoe/myfile.txt`.

So, the URL for that file would be something like: `/files/home/johndoe/myfile.txt`.

### OpenAPI support

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
```

## Path-параметры, содержащие пути

Предположим, что есть *операция пути* с путем `/files/{file_path}`.

Но вам нужно, чтобы `file_path` сам содержал *путь*, например, `home/johndoe/myfile.txt`.

Тогда URL для этого файла будет такой: `/files/home/johndoe/myfile.txt`.

### Поддержка OpenAPI

```

客户端中的 JSON 响应如下：

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
```

## 包含路径的路径参数

假设*路径操作*的路径为 `/files/{file_path}`。

但需要 `file_path` 中也包含*路径*，比如，`home/johndoe/myfile.txt`。

此时，该文件的 URL 是这样的：`/files/home/johndoe/myfile.txt`。

### OpenAPI 支持

OpenAPI 不支持声明包含路径的*路径参数*，因为这会导致测试和定义更加困难。

{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
```

## Paramètres de chemin contenant des chemins

Disons que vous avez une *fonction de chemin* liée au chemin `/files/{file_path}`.

Mais que `file_path` lui-même doit contenir un *chemin*, comme `home/johndoe/myfile.txt` par exemple.

Donc, l'URL pour ce fichier pourrait être : `/files/home/johndoe/myfile.txt`.

### Support d'OpenAPI

from docs_src.path_params.tutorial004 import app

client = TestClient(app)


def test_file_path():
    response = client.get("/files/home/johndoe/myfile.txt")
    print(response.content)
    assert response.status_code == 200, response.text
    assert response.json() == {"file_path": "home/johndoe/myfile.txt"}


def test_root_file_path():
    response = client.get("/files//home/johndoe/myfile.txt")
    print(response.content)

from fastapi import FastAPI

app = FastAPI()


@app.get("/files/{file_path:path}")
async def read_file(file_path: str):

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
```

## Pfad Parameter die Pfade enthalten

Angenommen, Sie haben eine *Pfadoperation* mit einem Pfad `/files/{file_path}`.

Aber `file_path` soll selbst einen *Pfad* enthalten, etwa `home/johndoe/myfile.txt`.

Sprich, die URL für diese Datei wäre etwas wie: `/files/home/johndoe/myfile.txt`.

### OpenAPI Unterstützung

    def iterfile():  # (1)
        with open(some_file_path, mode="rb") as file_like:  # (2)
            yield from file_like  # (3)
