Artık şunu döndürmek yerine:

```json
{"message": "Hello World"}
```

...bu response şunu döndürür:

```json
{
  "message": "Hello World"
}
```

Elbette JSON’u formatlamaktan çok daha iyi şekillerde bundan faydalanabilirsiniz. 😉

### `orjson` mı Response Model mi { #orjson-or-response-model }

input size | lib | MB/s | Allocated
--- | --- | --- | ---
regular | standard | 97 | 3.6MB
regular | jstream | 175 | 2.1MB
large | standard | 92 | 305MB
large | jstream | 404 | 69MB

In a real world scenario, including initialization and reader overhead from varying blob sizes, performance can be expected as below:

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

/// tip | 提示

注意，尽管你是通过 `http://127.0.0.1:8000/app` 访问，它仍显示 `root_path` 为 `/api/v1`，该值来自 `--root-path` 选项。

///

现在打开包含路径前缀、使用 Traefik 端口的 URL：[http://127.0.0.1:9999/api/v1/app](http://127.0.0.1:9999/api/v1/app)。

我们得到相同的响应：

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

response = requests.get("http://example.com/some/url")
```

The FastAPI counterpart API *path operation* could look like:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

See the similarities in `requests.get(...)` and `@app.get(...)`.
