tile38 一款开源的geo 数据库

tile38 是基于golang 编写的geo 数据库，支持地理空间索引、实时地理围栏，同时也支持leader-flower 的部署模型
备注： 下边测试一个简单的地理围栏功能

环境准备

• docker-compose 文件
  包含了一个简单的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"

 

运行&&测试地理围栏功能

启动

docker-compose up -d

使用

• 进入容器 app （tile38 服务）

docker-compose exec app sh

tile38-cli

 

• 添加webhook格式

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

 

• 添加数据围栏：

/ # 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"}

 

• 添加进入围栏区域的数据

SET fleet truck1 POINT 33.5123 -112.2693

• webhook 数据

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]}}

说明：
默认的webhook 数据会包含所有包含的类型，我们可以指定需要的类型

 

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

说明

tile38 使用简单，包含了rest 以及resp 协议的支持，同时webhook支持多种协议 http，https，redis，nats，grpc。。。
