查询参数 `q` 的类型为 `str`，默认值为 `None`，因此它是可选的。

## 额外的校验

我们打算添加约束条件：即使 `q` 是可选的，但只要提供了该参数，则该参数值**不能超过50个字符的长度**。

### 导入 `Query`

为此，首先从 `fastapi` 导入 `Query`：

{* ../../docs_src/query_params_str_validations/tutorial002.py hl[1] *}

## 使用 `Query` 作为默认值

现在，将 `Query` 用作查询参数的默认值，并将它的 `max_length` 参数设置为 50：

{* ../../docs_src/query_params_str_validations/tutorial002.py hl[9] *}

                                    {

                                        "minLength": 3,
                                        "maxLength": 50,

                                    },
                                    {"type": "null"},
                                ],

        ArtifactSpec managedB = createArtifactSpec("b", "5.0");

        ArtifactResolutionResult res = collect(a, managedB.artifact);
        assertEquals(
                createSet(new Object[] {a.artifact, managedB.artifact}), res.getArtifacts(), "Check artifact list");
        assertEquals("5.0", getArtifact("b", res.getArtifacts()).getVersion(), "Check version");
