這個範例不會實作回呼本身（那可能就只是一行程式碼），只會實作文件的部分。

/// tip

實際的回呼就是一個 HTTP 請求。

當你自己實作回呼時，可以使用像是 [HTTPX](https://www.python-httpx.org) 或 [Requests](https://requests.readthedocs.io/)。

## 撰寫回呼的文件化程式碼 { #write-the-callback-documentation-code }

這段程式碼在你的應用中不會被執行，我們只需要它來「文件化」說明那個「外部 API」應該長什麼樣子。

不過，你已經知道如何用 **FastAPI** 輕鬆為 API 建立自動文件。

所以我們會用同樣的方式，來文件化「外部 API」應該長什麼樣子... 也就是建立外部 API 應該實作的「路徑操作（們）」（那些「你的 API」會去呼叫的操作）。

                    times[1], // last access time
                    times[2], // last write time
                    times[3], // change time
                    TEST_ATTRIBUTES);

            // When & Then
            assertEquals(times[0], info.getCreateTime());

    private byte[] createMockFileBasicInfoBuffer() {
        // Create a buffer that represents FileBasicInfo data
        // FileBasicInfo typically contains creation time, last access time, last write time, change time, and attributes
        byte[] buffer = new byte[40];

        // Mock times (8 bytes each)
        for (int i = 0; i < 32; i++) {
            buffer[i] = (byte) (i % 256);
        }
