所以 OpenAPI为了相似的目的定义了自己的 <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.3.md#fixed-fields-20" class="external-link" target="_blank">`example`</a> (使用 `example`, 而不是 `examples`), 这也是文档 UI 所使用的 (使用 Swagger UI).

Esse é o motivo das versões atuais estarem em `0.x.x`, significando que em cada versão pode haver mudanças significativas, tudo isso seguindo as <a href="https://semver.org/lang/pt-BR/" class="external-link" target="_blank">convenções de controle de versão semântica.</a>

        assertEquals("PrunedTag [tag=a, id=null, css=test, attrName=null, attrValue=null]", tags[0].toString());

        tags = PrunedTag.parse("a[target=_blank]");
        assertEquals(1, tags.length);
        assertEquals("PrunedTag [tag=a, id=null, css=null, attrName=target, attrValue=_blank]", tags[0].toString());

        tags = PrunedTag.parse("a.link,div#123");
        assertEquals(2, tags.length);

Quando você precisar receber campos de formulário ao invés de JSON, você pode usar `Form`.

/// info | "Informação"

Para usar formulários, primeiro instale <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Ex: `pip install python-multipart`.

///

## Importe `Form`

Importe `Form` de `fastapi`:

```Python hl_lines="1"
{!../../docs_src/request_forms/tutorial001.py!}
```

That's why the current versions are still `0.x.x`, this reflects that each version could potentially have breaking changes. This follows the <a href="https://semver.org/" class="external-link" target="_blank">Semantic Versioning</a> conventions.

## 告诫

如果您需要执行繁重的后台计算，并且不一定需要由同一进程运行（例如，您不需要共享内存、变量等），那么使用其他更大的工具（如 <a href="https://docs.celeryq.dev" class="external-link" target="_blank">Celery</a>）可能更好。

它们往往需要更复杂的配置，即消息/作业队列管理器，如RabbitMQ或Redis，但它们允许您在多个进程中运行后台任务，甚至是在多个服务器中。
