only tested in window7 and redis windows binary env

Introduction

This is a basic demo for REST API using redis and for weather the redis cache is an hour

Start demo.exe and test following URL

Requirement

使用openweathermap.com的服务提供天气API

实现要求

  • 语言 Go
  • 框架 内置库，比如net/http encoding/json
  • 后端数据库 Redis或者SQLite，只需要一种即可

API 列表

  • POST /location
  • GET /location
  • GET /location/{name}
  • DELETE /location/{name}

POST /location

增加支持的城市，如果已存在于数据库，返回409，否则返回201

例子1

POST /location { "name": "Shanghai" }

201 Created

例子2

POST /location { "name": "Shanghai" }

201 Created

POST /location { "name": "Shanghai" }

409 Conflicted

GET /location 返回数据库中的所有城市

例子1

GET /location

200 OK []

例子2

POST /location { "name": "Shanghai" }

201 Created

POST /location { "name": "Beijing" }

201 Created

GET /location

200 OK ["Shanghai", "Beijing"]

GET /location/{name} 查询openweathermap.com，返回结果，因为天气数据更新不频繁，可缓存在数据库中，保留1个小时

不需要考虑查询openweathermap.com返回错误的情况

例子1

GET /location/Shanghai

200 OK { "weather": [ { "description": "few clouds", "icon": "02d", "id": 801, "main": "Clouds" } ] }

DELETE /location/{name}

例子1

DELETE /location/Shanghai

200 OK
