## JSON Lines { #json-lines }

在這些情況下，常見做法是傳送「**JSON Lines**」，這是一種每一行各包含一個 JSON 物件的格式。

回應的 content type 會是 `application/jsonl`（而不是 `application/json`），而本體內容會像這樣：

```json
{"name": "Plumbus", "description": "A multi-purpose household device."}
{"name": "Portal Gun", "description": "A portal opening device."}
{"name": "Meeseeks Box", "description": "A box that summons a Meeseeks."}
```
