And **FastAPI**'s `HTTPException` error class inherits from Starlette's `HTTPException` error class.

The only difference is that **FastAPI**'s `HTTPException` accepts any JSON-able data for the `detail` field, while Starlette's `HTTPException` only accepts strings for it.

So, you can keep raising **FastAPI**'s `HTTPException` as normally in your code.

    if (!this.route.address.equalsNonHost(address)) return false

    // If the host exactly matches, we're done: this connection can carry the address.

Pydantic 是 FastAPI 中所有数据验证和序列化的核心，当你在没有设默认值的情况下使用 `Optional` 或 `Union[Something, None]` 时，它具有特殊行为，你可以在 Pydantic 文档中阅读有关<a href="https://docs.pydantic.dev/latest/concepts/models/#required-optional-fields" class="external-link" target="_blank">必需可选字段</a>的更多信息。

### 使用Pydantic中的`Required`代替省略号(`...`)

如果你觉得使用 `...` 不舒服，你也可以从 Pydantic 导入并使用 `Required`：

```Python hl_lines="2  8"

		t.Fatal(err)
	}

	// Check if the reference format and input formats are same.
	if err = formatErasureV3Check(quorumFormat, formats[0]); err != nil {
		t.Fatal(err)
	}

	// QuorumFormat has .This field empty on purpose, expect a failure.
	if err = formatErasureV3Check(formats[0], quorumFormat); err == nil {
		t.Fatal("Unexpected success")
	}

	formats[0] = nil
	quorumFormat, err = getFormatErasureInQuorum(formats)
