Например, если клиент попытается отправить заголовок `tool` со значением `plumbus`, то в ответ он получит ошибку, сообщающую ему, что header-параметр `tool` не разрешен:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["header", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus",
        }
    ]
}
```

import org.apache.maven.api.Service;
import org.apache.maven.api.Session;
import org.apache.maven.api.annotations.Experimental;

* The process can be **terminated** (or "killed") by you, or by the operating system. At that point, it stops running/being executed, and it can **no longer do things**.
* Each application that you have running on your computer has some process behind it, each running program, each window, etc. And there are normally many processes running **at the same time** while a computer is on.

しかし、クライアントが`http://example.com/items/bar`（存在しない`item_id` `"bar"`）をリクエストした場合、HTTPステータスコード404（"not found"エラー）と以下のJSONレスポンスが返されます:

```JSON
{
  "detail": "Item not found"
}
```

/// tip | 豆知識

`HTTPException`を発生させる際には、`str`だけでなく、JSONに変換できる任意の値を`detail`パラメータとして渡すことができます。

`dict`や`list`などを渡すことができます。

これらは **FastAPI** によって自動的に処理され、JSONに変換されます。

## カスタムヘッダーの追加

import org.apache.maven.artifact.metadata.ArtifactMetadata;
import org.apache.maven.artifact.repository.ArtifactRepository;
import org.apache.maven.artifact.repository.metadata.RepositoryMetadataStoreException;

/**
 * Attach a POM to an artifact.
 *
 */
@Deprecated
public class ProjectArtifactMetadata extends AbstractArtifactMetadata {
    private final File file;

    public ProjectArtifactMetadata(Artifact artifact) {

```

</div>

Wenn Sie dann zu den URLs unter `/openapi.json`, `/docs` oder `/redoc` gehen, erhalten Sie lediglich einen `404 Not Found`-Fehler, wie:

```JSON
{
    "detail": "Not Found"
}

点击小锁图标，注销后，再执行同样的操作，则会得到 HTTP 401 错误：

```JSON
{
  "detail": "Not authenticated"
}
```

### 未激活用户

测试未激活用户，输入以下信息，进行身份验证：

用户名：`alice`

密码：`secret2`

然后，执行 `/users/me` 路径的 `GET` 操作。

显示下列**未激活用户**错误信息：

```JSON
{
  "detail": "Inactive user"
}
```

## 小结

使用本章的工具实现基于 `username` 和 `password` 的完整 API 安全系统。

Por exemplo, se o cliente tentar enviar um cabeçalho `tool` com o valor `plumbus`, ele irá receber uma resposta de **erro** informando que o parâmetro do cabeçalho `tool` não é permitido:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["header", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus",
        }
    ]
}
```

Por ejemplo, si el cliente intenta enviar un header `tool` con un valor de `plumbus`, recibirán un response de **error** indicando que el parámetro de header `tool` no está permitido:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["header", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus",
        }
    ]
}
```
