`File` 是直接繼承自 `Form` 的類別。

但請記住，當你從 `fastapi` 匯入 `Query`、`Path`、`File` 等時，它們其實是回傳特殊類別的函式。

///

/// tip

要宣告檔案本文，必須使用 `File`，否則參數會被解讀為查詢參數或本文（JSON）參數。

///

檔案會以「表單資料」上傳。

如果你將路徑操作函式（path operation function）的參數型別宣告為 `bytes`，**FastAPI** 會替你讀取檔案，你會以 `bytes` 取得內容。

請注意，這表示整個內容會存放在記憶體中，適合小檔案。

但在許多情況下，使用 `UploadFile` 會更好。

## 使用 `UploadFile` 的檔案參數 { #file-parameters-with-uploadfile }

將檔案參數型別設為 `UploadFile`：

		writeErrorResponseJSON(ctx, w, errorCodes.ToAPIErr(ErrAccessDenied), r.URL)
		return
	}

	kmsContext := kms.Context{"MinIO admin API": "KMSKeyStatusHandler"} // Context for a test key operation
	// 1. Generate a new key using the KMS.
	key, err := GlobalKMS.GenerateKey(ctx, &kms.GenerateKeyRequest{Name: keyID, AssociatedData: kmsContext})
	if err != nil {
		response.EncryptionErr = err.Error()

				case testClose:
					err := tw.Close()
					if !equalError(err, tf.wantErr) {
						t.Fatalf("test %d, Close() = %v, want %v", i, err, tf.wantErr)
					}
				default:
					t.Fatalf("test %d, unknown test operation: %T", i, tf)
				}
			}

			if v.file != "" {
				path := v.file
				if v.obscured {
					tf, err := obscuretestdata.DecodeToTempFile(path)
					if err != nil {

    status->status = tensorflow::errors::InvalidArgument(
        "Got a null or uninitialized `op` argument");
    return;
