tile38 是基於golang 編寫的geo 資料庫，支援地理空間索引、實時地理圍欄，同時也支援leader-flower 的部署模型
備註： 下邊測試一個簡單的地理圍欄功能

環境準備

• docker-compose 檔案
  包含了一個簡單的webhook 工具

 

version: "3"

services:

  app:
 

    image: tile38/tile38

    ports:

    - "9851:9851"

  benthos:

    image: jeffail/benthos

    volumes:
 

    - "./conf/webhook.yaml:/benthos.yaml"

    ports:

    - "4195:4195"

 

執行&&測試地理圍欄功能

啟動

docker-compose up -d
 

使用

• 進入容器 app （tile38 服務）

docker-compose exec app sh

tile38-cli

 

• 新增webhook格式

SETHOOK name endpoint [META name value ...] [EX seconds] NEARBY|WITHIN|INTERSECTS key FENCE [DETECT what] [COMMANDS which] param [param ...]

 

• 新增資料圍欄：

/ # tile38-cli

127.0.0.1:9851> SETHOOK warehouse http://benthos:4195/ NEARBY fleet FENCE POINT 33.462 -112.268 6000

{"ok":true,"elapsed":"118.008µs"}

 

• 新增進入圍欄區域的資料

SET fleet truck1 POINT 33.5123 -112.2693

• webhook 資料

docker-compose logs -f benthos

效果

benthos_1 | get email message: {"command":"set","group":"5c395823b1e3cb00012724bc","detect":"enter","hook":"warehouse","key":"fleet","time":"2019-01-12T02:59:47.766263252Z","id":"dalong","object":{"type":"Point","coordinates":[-112.2693,33.5123]}}

benthos_1 | get email message: {"command":"set","group":"5c395823b1e3cb00012724bc","detect":"inside","hook":"warehouse","key":"fleet","time":"2019-01-12T02:59:47.766263252Z","id":"dalong","object":{"type":"Point","coordinates":[-112.2693,33.5123]}}

說明：
預設的webhook 資料會包含所有包含的型別，我們可以指定需要的型別

 

NEARBY fleet FENCE DETECT inside,outside POINT 33.462 -112.268 6000

說明

tile38 使用簡單，包含了rest 以及resp 協議的支援，同時webhook支援多種協議 http，https，redis，nats，grpc。。。
