# 更大的应用 - 多个文件 { #bigger-applications-multiple-files }

如果你正在开发一个应用程序或 Web API，很少会将所有的内容都放在一个文件中。

**FastAPI** 提供了一个方便的工具，可以在保持所有灵活性的同时构建你的应用程序。

/// info | 信息

如果你来自 Flask，那这将相当于 Flask 的 Blueprints。

## 一个文件结构示例 { #an-example-file-structure }

假设你的文件结构如下：

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   ├── dependencies.py
│   └── routers
│   │   ├── __init__.py
│   │   ├── items.py

        assertEquals("arg1", pythonJob.argList.get(0));

        pythonJob.arg("arg2");
        assertEquals(2, pythonJob.argList.size());
        assertEquals("arg2", pythonJob.argList.get(1));
    }

    // Test multiple arguments addition
    @Test
    public void test_args() {
        assertTrue(pythonJob.argList.isEmpty());

        PythonJob result = pythonJob.args("arg1", "arg2", "arg3");

   * Clears fields that are no longer needed after this future has completed -- or at least all its
   * inputs have completed (more precisely, after {@link #handleAllCompleted()} has been called).
   * Often called multiple times (that is, both when the inputs complete and when the output
   * completes).
   *

   * description of CL 265462958.

    // we try hard to make them robust in practice.  We could additionally try to add in a system
    // load timeout multiplier.  Or we could try to use a CPU time bound instead of wall clock time
    // bound.  But these ideas are harder to implement.  We do not try to detect or handle a

## More details about `SecurityScopes` { #more-details-about-securityscopes }

You can use `SecurityScopes` at any point, and in multiple places, it doesn't have to be at the "root" dependency.

/// danger | 警告

ユーザーの平文のパスワードは絶対に保存しないでください。常に検証できる「安全なハッシュ」を保存してください。

## 複数のモデル { #multiple-models }

ここでは、パスワードフィールドをもつモデルがどのように見えるのか、また、どこで使われるのか、大まかなイメージを紹介します:

{* ../../docs_src/extra_models/tutorial001_py310.py hl[7,9,14,20,22,27:28,31:33,38:39] *}

そのために、`None` が有効な型であることを宣言しつつ、単にデフォルト値を宣言しません:

{* ../../docs_src/query_params_str_validations/tutorial006c_an_py310.py hl[9] *}

## クエリパラメータのリスト / 複数の値 { #query-parameter-list-multiple-values }

クエリパラメータを明示的に `Query` で定義すると、値のリストを受け取るように宣言したり、言い換えると複数の値を受け取るように宣言したりすることもできます。

例えば、URL内に複数回出現するクエリパラメータ`q`を宣言するには以下のように書きます:
