## Developing

If you already cloned the [fastapi repository](https://github.com/fastapi/fastapi) and you want to deep dive in the code, here are some guidelines to set up your environment.

### Install requirements

Create a virtual environment and install the required packages with [`uv`](https://github.com/astral-sh/uv):

      }

    /**
     * Sets the interval between HTTP/2 and web socket pings initiated by this client. Use this to
     * automatically send ping frames until either the connection fails or it is closed. This keeps
     * the connection alive and may detect connectivity failures.
     *
     * If the server does not respond to each ping with a pong within `interval`, this client will

* L'apprentissage profond (ou **Deep Learning**) : est un sous-domaine du **Machine Learning**, donc les mêmes raisons s'appliquent. Avec la différence qu'il n'y a pas une unique feuille de calcul de nombres à multiplier, mais une énorme quantité d'entre elles, et dans de nombreux cas,...

在回傳給用戶端之前，它們會被轉成對應的值（此例為字串）：

{* ../../docs_src/path_params/tutorial005_py310.py hl[18,21,23] *}

你的用戶端會收到像這樣的 JSON 回應：

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

## 包含路徑的路徑參數 { #path-parameters-containing-paths }

假設你有一個路徑為 `/files/{file_path}` 的「路徑操作」。

但你需要 `file_path` 本身就包含一個「路徑」，像是 `home/johndoe/myfile.txt`。

* **Machine Learning**: normalmente requiere muchas multiplicaciones de "matrices" y "vectores". Piensa en una enorme hoja de cálculo con números y multiplicando todos juntos al mismo tiempo.

        return new SmbResourceLocatorImpl(ctx, smbUrl(spec));
    }

    @Test
    @DisplayName("getName returns last path segment; falls back logically")
    void testGetNameVariants() {
        // file name from deep path
        SmbResourceLocatorImpl a = locator("smb://server/share/dir/file.txt");
        assertEquals("file.txt", a.getName());

        // share name with trailing slash when only share present

    }

    @Test
    public void test_defaultMaxGroupDepth() {
        EntraIdAuthenticator authenticator = new EntraIdAuthenticator();

        // Test that default max depth (10) prevents deep recursion
        // Depth 100 should exceed default and return empty
        Pair<String[], String[]> result = authenticator.getParentGroup(null, "test-id", 100);
        assertNotNull(result);

    return Platform.newLinkedHashSetWithExpectedSize(valueSetCapacity);
