} else if("badRequest".equals(type)) {
	redirectPage.append("/error/badrequest/");
	response.sendRedirect(redirectPage.toString());
} else if(!"badAuth".equals(type)) {
	redirectPage.append("/error/notfound/?url=");
	redirectPage.append(java.net.URLEncoder.encode(requestUri , "UTF-8"));
	response.sendRedirect(redirectPage.toString());
}

} else if("badRequest".equals(type)) {
	redirectPage.append("/error/badrequest/");
	response.sendRedirect(redirectPage.toString());
} else if(!"badAuth".equals(type)) {
	redirectPage.append("/error/notfound/?url=");
	redirectPage.append(java.net.URLEncoder.encode(requestUri , "UTF-8"));

}

constraints.Range.message = {item} 必須在 {min} 到 {max} 之間。
constraints.SafeHtml.message = {item} 包含危險的 HTML 內容。
constraints.ScriptAssert.message = 腳本表達式 "{script}" 不為 true。
constraints.URL.message = {item} 不是有效的URL。
constraints.Required.message = {item} 是必需的。
constraints.TypeInteger.message = {item} 必須是數字。
constraints.TypeLong.message = {item} 必須是數字。
constraints.TypeFloat.message = {item} 必須是數字。

Ini akan menjadi gerbang utama untuk membuat semua API anda.

### Langkah 3: Buat *operasi path*

#### Path

"Path" atau jalur di sini merujuk ke bagian URL terakhir dimulai dari `/` pertama.

Sehingga, URL seperti:

```
https://example.com/items/foo
```

...path-nya adalah:

```
/items/foo
```

/// info

Este será o principal ponto de interação para criar toda a sua API.

### Passo 3: crie uma *rota*

#### Rota

"Rota" aqui se refere à última parte da URL, começando do primeiro `/`.

Então, em uma URL como:

```
https://example.com/items/foo
```

...a rota seria:

```
/items/foo
```

/// info | Informação

package org.codelibs.fess.test.net.protocol.xxx3;

import java.io.IOException;
import java.net.URL;
import java.net.URLConnection;
import java.net.URLStreamHandler;

public class Handler extends URLStreamHandler {

    public static final String PROTOCOL_TYPE = "test";

    @Override
    protected URLConnection openConnection(URL u) throws IOException {
        return null;
    }

      },
      "createTime": {
        "type": "long"
      },
      "lastModified": {
        "type": "long"
      },
      "sessionId": {
        "type": "keyword"
      },
      "url": {
        "type": "keyword"
      }
    }

Sie definieren auch auf irgendeine Weise, zu welchen **Momenten** Ihre Anwendung diese Requests oder Events sendet.

Und **Ihre Benutzer** definieren auf irgendeine Weise (zum Beispiel irgendwo in einem Web-Dashboard) die **URL**, an die Ihre Anwendung diese Requests senden soll.

Der Abschnitt mit:

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

{% endraw %}

... generiert also einen Link zu derselben URL, welche von der *Pfadoperation-Funktion* `read_item(id=id)` gehandhabt werden würde.

Mit beispielsweise der ID `42` würde dies Folgendes ergeben:

```html
<a href="/items/42">
```

Logo, a seção com:

{% raw %}

```jinja
<a href="{{ url_for('read_item', id=id) }}">
```

{% endraw %}

...irá gerar um link para a mesma URL que será tratada pela *path operation function* `read_item(id=id)`.

Por exemplo, com um ID de `42`, isso renderizará:

```html
<a href="/items/42">
```
