```Python
q: Union[str, None] = Query(default=None, max_length=50)
```

将会校验数据，在数据无效时展示清晰的错误信息，并在 OpenAPI 模式的*路径操作*中记录该参​​数。

## 添加更多校验

你还可以添加 `min_length` 参数：

```Python hl_lines="10"
{!../../docs_src/query_params_str_validations/tutorial003.py!}
```

## 添加正则表达式

你可以定义一个参数值必须匹配的<abbr title="正则表达式或正则是定义字符串搜索模式的字符序列。">正则表达式</abbr>：

```Python hl_lines="11"

   * @throws NullPointerException if {@code s} is null (in contrast to {@link
   *     Integer#parseInt(String)})
   */
  @CanIgnoreReturnValue
  public static int parseUnsignedInt(String s) {
    return parseUnsignedInt(s, 10);
  }

  /**
   * Returns the unsigned {@code int} value represented by a string with the given radix.
   *
   * <p><b>Java 8+ users:</b> use {@link Integer#parseUnsignedInt(String, int)} instead.
   *

   * @throws NullPointerException if {@code s} is null (in contrast to {@link
   *     Integer#parseInt(String)})
   */
  @CanIgnoreReturnValue
  public static int parseUnsignedInt(String s) {
    return parseUnsignedInt(s, 10);
  }

  /**
   * Returns the unsigned {@code int} value represented by a string with the given radix.

Support for `separate_input_output_schemas` was added in FastAPI `0.102.0`. 🤓

### Same Schema for Input and Output Models in Docs

And now there will be one single schema for input and output for the model, only `Item`, and it will have `description` as **not required**:

        #  But it is possible that unanticipated problems occurs, so be careful!
        #; typeMappingMap = map:{
        #    # AutoMapping for Numeric and Decimal, (1-9,0): INTEGER, (10-18,0): BIGINT, else: NUMERIC
        #    ; NUMERIC = $$AutoMapping$$ ; DECIMAL = $$AutoMapping$$
        #}
    }
    # - - - - - - - - - -/
}
