你希望把與使用者相關的「路徑操作 (path operation)」從其他程式碼分離，讓結構更有條理。

但它仍然是同一個 FastAPI 應用程式 / Web API 的一部分（屬於同一個「Python 套件」）。

你可以使用 `APIRouter` 為該模組建立路徑操作。

### 匯入 `APIRouter` { #import-apirouter }

你可以像對 `FastAPI` 類別那樣匯入並建立一個「實例」：

{* ../../docs_src/bigger_applications/app_an_py310/routers/users.py hl[1,3] title["app/routers/users.py"] *}

### 使用 `APIRouter` 宣告路徑操作 { #path-operations-with-apirouter }

然後用它來宣告你的路徑操作。

 *   <li>A key is contained in the multimap if and only if it maps to at least one value. Any
 *       operation that causes a key to have zero associated values has the effect of
 *       <i>removing</i> that key from the multimap.
 *   <li>The total entry count is available as {@link #size}.
 *   <li>Many complex operations become easier; for example, {@code
 *       Collections.min(multimap.values())} finds the smallest value across all keys.

     * @param out the outgoing buffer containing the request
     * @param off the offset into the outgoing buffer
     * @param length the length of data to send
     * @param inB the buffer to receive the response
     * @return the number of bytes received
     * @throws IOException if an I/O error occurs during the operation
