# 雾霾天气查询网页

# 问题描述

雾霾的频繁出现已严重的影响到人们的出行，对人们的健康造成了重大影响。因此，能在出行前查看雾霾的指数，并采取相应的措施来把雾霾的影响降到最小就显得尤为重要。本系统在分析多种因子的影响下，设计一个手机端天气查询网站。

包含以下功能：

a.定位功能：将定位城市保存在服务器端，并同时显示在客户端。

b.界面设计：包含显示天气和空气质量指数的动态显示。

c.天气详情和空气质量指数：定位后的城市在服务器端获取后，传给天气详情界面，通过所传城市用百度天气api获取对应的天气详情和空气质量指数，并保存在服务器端。

后续可以添加出行建议等功能。

# 主体设计

根据任务需求，我们计划设计一个适配手机端的天气查询网页，页面信息包含空气质量指数、温度等，并包含了未来10小时的预报。同时产品同学制作出相应的原型图交付给开发同学。开发同学根据原型图确定好技术选型，从而开始着手开发。

原型图：Figma原型图 (opens new window)

下面具体阐述系统的技术方案：

# 文件目录

# 前端

目前只有一个页面，所以代码都写在index.vue中，由于用了echarts画图，所以中间的配置项特别长，其实页面可以分成几个组件，这样更方便维护。

# 后端

config用来配置允许跨域，controller用来相应请求，且共享一个Address对象，目前只考虑了单用户的情况，多用户访问的话可能会有问题（待验证）。domain里是一个Address的POJO，包含ip、province、city还有一个画图需要的属性。utils里封装了获取ip的方法。

# 效果展示

访问页面后，自动定位到所在城市，结果如下图：

自定义城市后，如河北省石家庄市，结果如下：

服务端打印所有查询结果：

# 遇到的问题及解决方法

通过ip判断是否为本地用户，若是则发送请求到http://pv.sohu.com/cityjson?ie=utf-8 (opens new window)可以获取外网ip及所在城市。

每次数据更新后都要重新setOption来更新。

暂时用一个hashmap来接收请求参数，所有参数会存在hashmap的第一个键里，取出来后转成json对象再去按键取值。后续可以看看哪里出问题了，或者转成一个get请求。

到时候用别的api吧。

# 接口

# /api/location

描述：根据请求过来的ip通过百度的ip查询接口获取它的位置信息。本地用户会特殊处理，参考问题1。

请求类型：POST 请求参数：无

{
    "data": {
        "country": "中国",
        "country_id": "CN",
        "area": "西北",

# /api/weather

描述：目前这个api会配合/api/location一起使用，从而保证ip不为空，然后通过ip查询该城市的天气信息。返回的数据是经过处理的（信息太多，方便前端处理）。后续还需要优化，与/api/location解耦。 请求类型：POST 请求参数：无
