使用上面的任何方法，它在 `/docs` 中看起来都是这样的:

## 技术细节

关于 `example` 和 `examples`...

JSON Schema在最新的一个版本中定义了一个字段 <a href="https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.9.5" class="external-link" target="_blank">`examples`</a> ，但是 OpenAPI 基于之前的一个旧版JSON Schema，并没有 `examples`.

                            "content": {"application/json": {"schema": {}}},
                        },
                        "422": {
                            "description": "Validation Error",
                            "content": {
                                "application/json": {
                                    "schema": {

So, even with the code above that doesn't use Pydantic explicitly, FastAPI is using Pydantic to convert those standard dataclasses to Pydantic's own flavor of dataclasses.

And of course, it supports the same:

* data validation
* data serialization
* data documentation, etc.

This works the same way as with Pydantic models. And it is actually achieved in the same way underneath, using Pydantic.

Dado que son parte de la URL son strings "naturalmente".

Pero cuando los declaras con tipos de Python (en el ejemplo arriba, como `int`) son convertidos a ese tipo y son validados con él.

Todo el proceso que aplicaba a los parámetros de path también aplica a los parámetros de query:

Como eles são parte da URL, eles são "naturalmente" strings.

Mas quando você declara eles com os tipos do Python (no exemplo acima, como `int`), eles são convertidos para aquele tipo e validados em relação a ele.

- `kubeadm`: added a new "kubeadm config validate" command that can be used to
  validate any input config file. Use the `--config` flag to pass a config file
  to it. See the command `--help` screen for more information. As a result of adding
  this new command, enhance the validation capabilities of the existing "kubeadm
