爲 Service 添加路由（Route）
請求
$ curl -i -X POST \ --url http://localhost:8001/services/example-service/routes \ --data 'hosts[]=example.com'
爲 Service example-service 添加了 example.com 相關的路由

可以看到 HTTP/1.1 201 Created，表示創建成功
兩點疑問：
- 從響應看 service 節點是數組，是否表示一個Route 可以被綁定至多個 Service？
- 但是從創建時的參數 hosts[] 來看，一個 Route 可以映射多個域名的請求，如果是多個Service，如何路由？
通過 Kong 轉發請求

響應的 html 內容是 Service 配置的 mockbin.org 網站的頁面，
- 證明 Route 已經將來自 example.com 的請求轉發至配置的服務（mockbin.org）
- Route 也將響應轉發至了請求發起方
總結
- 每個 Service 對應一個隱藏在其後的 API（創建參數 url 指定的地址）
- 每個 Service 可以定義多個 Route ,進而將符合這些 Route 定義的請求通過 Serive 轉發至 API
