## Conclusion

With this you should have a basic understanding of what **environment variables** are and how to use them in Python.

You can also read more about them in the <a href="https://en.wikipedia.org/wiki/Environment_variable" class="external-link" target="_blank">Wikipedia for Environment Variable</a>.

### 他のAPIドキュメント

次に、<a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>にアクセスします。

先ほどとは異なる、自動生成された対話的APIドキュメントが表示されます (<a href="https://github.com/Rebilly/ReDoc" class="external-link" target="_blank">ReDoc</a>によって提供):

このため、**FastAPI**自体が代替のAPIドキュメントを提供します（ReDocを使用）。これは、 <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a> にアクセスすると確認できます。

同様に、互換性のあるツールが多数あります（多くの言語用のコード生成ツールを含む）。

## Pydantic

        File source = new File(new File(getBasedir(), getProjectsDirectory()), name);
        File target = new File(new File(getBasedir(), "target"), name);
        FileUtils.copyDirectoryStructureIfModified(source, target);
        return new File(target, "pom.xml");
    }

    protected MavenExecutionRequest createMavenExecutionRequest(File pom) throws Exception {

        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!}
```

Standardmäßig konvertiert **FastAPI** diesen Rückgabewert automatisch nach JSON, mithilfe des `jsonable_encoder`, der in [JSON-kompatibler Encoder](../tutorial/encoder.md){.internal-link target=_blank} erläutert wird.

Dann würde es hinter den Kulissen diese JSON-kompatiblen Daten (z. B. ein `dict`) in eine `JSONResponse` einfügen, die zum Senden der Response an den Client verwendet würde.
