要了解所有的可用选项，请查看 [Pydantic 的类型概览](https://docs.pydantic.dev/latest/concepts/types/)。你将在下一章节中看到一些示例。

例如，在 `Image` 模型中我们有一个 `url` 字段，我们可以把它声明为 Pydantic 的 `HttpUrl`，而不是 `str`：

{* ../../docs_src/body_nested_models/tutorial005_py310.py hl[2,8] *}

该字符串将被检查是否为有效的 URL，并在 JSON Schema / OpenAPI 文档中进行记录。

## 带有一组子模型的属性 { #attributes-with-lists-of-submodels }

你还可以将 Pydantic 模型用作 `list`、`set` 等的子类型：

      },
      "errorName": {
        "type": "keyword"
      },
      "errorLog": {
        "type": "keyword"
      },
      "errorCount": {
        "type": "integer"
      },
      "lastAccessTime": {
        "type": "long"
      },
      "configId": {
        "type": "keyword"
      }

Він матиме операцію шляху, яка отримуватиме тіло `Invoice`, і параметр запиту `callback_url`, що міститиме URL для зворотного виклику.

/**
 * Protocols that OkHttp implements for [ALPN][ietf_alpn] selection.
 *
 * ## Protocol vs Scheme
 *
 * Despite its name, [java.net.URL.getProtocol] returns the [scheme][java.net.URI.getScheme] (http,
 * https, etc.) of the URL, not the protocol (http/1.1, spdy/3.1, etc.). OkHttp uses the word
 * *protocol* to identify how HTTP messages are framed.
