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

To achieve this, you can use the command line option `--root-path` like:

<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>

Podría verse como esto:

```JSON  hl_lines="7"

  "name": "frontend-app",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",

    this.parameters = parameters;
  }

  /** Returns the top-level media type. For example, {@code "text"} in {@code "text/plain"}. */
  public String type() {
    return type;
  }

  /** Returns the media subtype. For example, {@code "plain"} in {@code "text/plain"}. */
  public String subtype() {
    return subtype;
  }

  /** Returns a multimap containing the parameters of this media type. */

import java.io.IOException;

import java.security.NoSuchAlgorithmException;

public class EnableVersioning {
  /** MinioClient.enableVersioning() example. */
  public static void main(String[] args)
      throws IOException, NoSuchAlgorithmException, InvalidKeyException {
    try {
      /* play.min.io for test and development. */
      MinioClient minioClient =
          MinioClient.builder()

Diese könnte so aussehen:

# Advanced Middleware { #advanced-middleware }

In the main tutorial you read how to add [Custom Middleware](../tutorial/middleware.md){.internal-link target=_blank} to your application.

And then you also read how to handle [CORS with the `CORSMiddleware`](../tutorial/cors.md){.internal-link target=_blank}.

In this section we'll see how to use other middlewares.
