# 路径参数和数值校验

与使用 `Query` 为查询参数声明更多的校验和元数据的方式相同，你也可以使用 `Path` 为路径参数声明相同类型的校验和元数据。

## 导入 Path

首先，从 `fastapi` 导入 `Path`：

        // of the fixedInputData (The default implementation has this format)</li>
        // with the parameters
        // <li>1. KDFCounterParameters(ki, null, "Label || 0x00 || Context || [L]_2]", 8);

        // all fixed inputs go into the suffix:
        // + label
        System.arraycopy(label, 0, suffix, 0, label.length);
        // + 1 byte 0x00
        // + context

        buffer.append(toId(model));

        Path pomPath = model.getPomPath();
        if (pomPath != null) {
            buffer.append(" (").append(pomPath).append(')');
        }

        return buffer.toString();
    }

    static String toPath(Model model) {
        String path = "";

        if (model != null) {
            Path pomPath = model.getPomPath();

            if (pomPath != null) {

            return org.apache.maven.api.services.Source.fromPath(file.toPath());
        } else if (source instanceof FileSource fs) {
            return org.apache.maven.api.services.Source.fromPath(fs.getPath());
        } else if (source != null) {
            return new org.apache.maven.api.services.Source() {
                @Override
                public Path getPath() {
                    return null;
                }

            None if separate_input_output_schemas else "validation"
        )
        inputs = [
            (field, override_mode or field.mode, field._type_adapter.core_schema)
            for field in fields
        ]
        field_mapping, definitions = schema_generator.generate_definitions(
            inputs=inputs
        )
        return field_mapping, definitions  # type: ignore[return-value]

# Path Parameters and Numeric Validations

In the same way that you can declare more validations and metadata for query parameters with `Query`, you can declare the same type of validations and metadata for path parameters with `Path`.

## Import Path

First, import `Path` from `fastapi`, and import `Annotated`:

# Path Operationの高度な設定

## OpenAPI operationId

/// warning | "注意"

あなたがOpenAPIの「エキスパート」でなければ、これは必要ないかもしれません。

///

*path operation* で `operation_id` パラメータを利用することで、OpenAPIの `operationId` を設定できます。

`operation_id` は各オペレーションで一意にする必要があります。

```

### *path operation関数* の名前をoperationIdとして使用する
