## Eine benutzerdefinierte `PNGStreamingResponse` { #a-custom-pngstreamingresponse }

In den obigen Beispielen wurden die Datenbytes gestreamt, aber die Response hatte keinen `Content-Type`-Header, sodass der Client nicht wusste, welchen Datentyp er erhielt.

          $boxElement.addClass("suggestorBox");
          $boxElement.attr({
            role: "listbox",
            "aria-label": "Search suggestions"
          });

          // Apply default or custom CSS styles
          $boxElement.css({
            display: "none",
            position: "absolute",
            "text-align": "left",
            "font-size": $element.css("font-size")
          });

from your test's `tearDown()`.

### API

#### MockResponse

Mock responses default to an empty response body and a `200` status code.
You can set a custom body with a string, input stream or byte array. Also
add headers with a fluent builder API.

### Java
```java
MockResponse response = new MockResponse.Builder()

## Combina responses predefinidos y personalizados { #combine-predefined-responses-and-custom-ones }

Es posible que desees tener algunos responses predefinidos que se apliquen a muchas *path operations*, pero que quieras combinarlos con responses personalizados necesarios por cada *path operation*.

## Vordefinierte und benutzerdefinierte Responses kombinieren { #combine-predefined-responses-and-custom-ones }

Möglicherweise möchten Sie einige vordefinierte Responses haben, die für viele *Pfadoperationen* gelten, Sie möchten diese jedoch mit benutzerdefinierten Responses kombinieren, die für jede *Pfadoperation* erforderlich sind.

### 串流位元組 { #stream-bytes }

一個主要用例是串流 `bytes` 而非字串，當然可以這麼做。

## 自訂 `PNGStreamingResponse` { #a-custom-pngstreamingresponse }

在上述範例中，雖然串流了資料位元組，但回應沒有 `Content-Type` 標頭，因此用戶端不知道接收到的是哪種資料型別。

你可以建立 `StreamingResponse` 的自訂子類別，將 `Content-Type` 標頭設定為你要串流的資料型別。
