Alle Codeblöcke können kopiert und direkt verwendet werden (da es sich um getestete Python-Dateien handelt).

Um eines der Beispiele auszuführen, kopieren Sie den Code in eine Datei `main.py`, und starten Sie `uvicorn` mit:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

Все блоки кода можно копировать и использовать напрямую (на самом деле это проверенные файлы Python).

Чтобы запустить любой из примеров, скопируйте код в файл `main.py` и запустите `uvicorn` с параметрами:

<div class="termy">

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

# 表单数据

接收的不是 JSON，而是表单字段时，要使用 `Form`。

/// info | "说明"

要使用表单，需预先安装 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>。

例如，`pip install python-multipart`。

///

## 导入 `Form`

从 `fastapi` 导入 `Form`：

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

## 定义 `Form` 参数

创建表单（`Form`）参数的方式与 `Body` 和 `Query` 一样：

import org.slf4j.LoggerFactory;

import com.fasterxml.jackson.core.type.TypeReference;
import com.fasterxml.jackson.databind.ObjectMapper;

public abstract class PasswordBasedExtractor extends AbstractExtractor {

    private static final Logger logger = LoggerFactory.getLogger(PasswordBasedExtractor.class);

    protected Map<Pattern, String> passwordMap = new HashMap<>();

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import jakarta.annotation.Resource;

/**
 * @author shinsuke
 *
 */
public class ZipExtractor extends AbstractExtractor {
    private static final Logger logger = LoggerFactory.getLogger(ZipExtractor.class);

    @Resource
    protected ArchiveStreamFactory archiveStreamFactory;

    protected long maxContentSize = -1;

    @Override

            val versionInfo = Gson().fromJson(jsonText, VersionDownloadInfo::class.java)
            println("updating wrapper to $label version: ${versionInfo.version} (downloadUrl: ${versionInfo.downloadUrl})")
            wrapperTask.get().distributionUrl = versionInfo.downloadUrl
        }
    }
}

@GwtCompatible
@ElementTypesAreNonnullByDefault
public class MapsTransformValuesUnmodifiableIteratorTest extends MapInterfaceTest<String, String> {
  // TODO(jlevy): Move shared code of this class and MapsTransformValuesTest
  // to a superclass.

  public MapsTransformValuesUnmodifiableIteratorTest() {
    super(true, true, false /*supportsPut*/, true, true, false);
  }

  private static class UnmodifiableIteratorMap<K, V> extends ForwardingMap<K, V> {

# テスト

<a href="https://www.starlette.io/testclient/" class="external-link" target="_blank">Starlette</a> のおかげで、**FastAPI** アプリケーションのテストは簡単で楽しいものになっています。

<a href="https://www.python-httpx.org" class="external-link" target="_blank">HTTPX</a> がベースなので、非常に使いやすく直感的です。

これを使用すると、**FastAPI** と共に <a href="https://docs.pytest.org/" class="external-link" target="_blank">pytest</a> を直接利用できます。

## `TestClient` を使用

`TestClient` をインポートします。
