這意味著從環境變數中讀取的**任何值**在 Python 中都將是一個 `str`，任何型別轉換或驗證都必須在程式碼中完成。

你將在[進階使用者指南 - 設定和環境變數](./advanced/settings.md)中了解更多關於使用環境變數處理**應用程式設定**的資訊。

## `PATH` 環境變數

有一個**特殊的**環境變數稱為 **`PATH`**，作業系統（Linux、macOS、Windows）用它來查找要執行的程式。

`PATH` 變數的值是一個長字串，由 Linux 和 macOS 上的冒號 `:` 分隔的目錄組成，而在 Windows 上則是由分號 `;` 分隔的。

例如，`PATH` 環境變數可能如下所示：

//// tab | Linux, macOS

```plaintext
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
```

    try {
      val requestHeaders = stream.takeHeaders()
      var path: String? = null
      var i = 0
      val size = requestHeaders.size
      while (i < size) {
        if (requestHeaders.name(i) == Header.TARGET_PATH_UTF8) {
          path = requestHeaders.value(i)
          break
        }
        i++
      }
      if (path == null) {
        // TODO: send bad request error
        throw AssertionError()

        assertEquals("Singleton context is already initialized", e.getMessage());
    }

    @Test
    void testInitLoadsJcifsPropertiesFile(@TempDir Path tempDir) throws IOException, CIFSException {
        // Test that jcifs.properties file is loaded
        Path jcifsPropertiesPath = tempDir.resolve("jcifs.properties");
        Files.writeString(jcifsPropertiesPath, "jcifs.smb.client.nativeOs=FileOS");

These are the special functions that you can put in *path operation function* parameters or dependency functions with `Annotated` to get data from the request.

It includes:

* `Query()`
* `Path()`
* `Body()`
* `Cookie()`
* `Header()`
* `Form()`
* `File()`

You can import them all directly from `fastapi`:

```python
from fastapi import Body, Cookie, File, Form, Header, Path, Query
```

::: fastapi.Query

windows_comment: >
   From the stack trace it looks like you are hitting windows path length limit.
      * Try to disable path length limit on Windows 10.
        * Refer [disable path length limit instructions guide.](https://mspoweruser.com/ntfs-260-character-windows-10/)
   

     * For example, if this type is {@link #MODULES}, then the option is {@code "--module-path"}
     * followed by the specified path elements.
     *
     * @param paths the path to format as a tool option
     * @return the option associated to this path type followed by the given path elements,
     *         or an empty array if there is no path element

## Detalles

El primer `"/static"` se refiere al sub-path en el que esta "sub-aplicación" será "montada". Por lo tanto, cualquier path que comience con `"/static"` será manejado por ella.

El `directory="static"` se refiere al nombre del directorio que contiene tus archivos estáticos.

Para conseguir isso, você pode usar a opção de linha de comando `--root-path` assim:

<div class="termy">

```console
$ fastapi run main.py --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>

Se você usar Hypercorn, ele também tem a opção `--root-path`.
