Unity制作天气预报

一、前言

使用Unity制作天气预报最难的一点就是没有合适的天气接口，在网上找了好多才找到一个合适的接口。

这个网站注册成功后可以免费查找2000次很适合小伙伴练习使用。

二、思路

制作天气预报思路我将其分为3步：
①获取当前位置地区信息
②通过地区id获取天气信息
③UI布局显示

三、正文

3.1获取当前位置信息

百度地图API

http://api.map.baidu.com/location/ip?ak=bretF4dm6W5gqjQAXuvP0NXW6FeesRXb&coor=bd09ll

Json信息

{“address”:“CN|\u6d59\u6c5f|\u676d\u5dde|None|CHINANET|0|0”,“content”:{“address”:”\u6d59\u6c5f\u7701\u676d\u5dde\u5e02″,“address_detail”:{“city”:”\u676d\u5dde\u5e02″,“city_code”:179,“district”:””,“province”:”\u6d59\u6c5f\u7701″,“street”:””,“street_number”:””},“point”:{“x”:“120.21937542”,“y”:“30.25924446”}},“status”:0}

Json在线解析工具

解析后信息
《Unity制作天气预报》
然后写一个类接收解析后的信息

#region 返回的城市名字等数据类
public class CityData
{ 
    public string address;
    public Content content;
    public int status;

}
public class Content
{ 
    public string address;
    public Address_Detail address_detail;
    public Point point;
}
public class Address_Detail
{ 
    public string city;
    public int city_code;
    public string district;
    public string province;
    public string street;
    public string street_number;
}

public class Point
{ 
    public string x;
    public string y;
}
#endregion

ps：这里要注意字段命名要相同，否则会接收不到数据

通过百度地图API获取的信息位置不是标准Json，所以我们要对这些数据进行解析一下

3.2获取天气信息

天气接口

http://www.tianqiapi.com/index/doc

进入这个网站注册登录
《Unity制作天气预报》
《Unity制作天气预报》

    //获取天气信息格式
    string Weatherurl = "https://v0.yiketianqi.com/api?version=v61&appid=注册后的id号&appsecret=密钥&cityid=";

用户id和密钥设置完成后 通过地区id访问获取本地天气信息

{“cityid”:“101210101”,“date”:“2021-02-23”,“week”:”\u661f\u671f\u4e8c”,“update_time”:“10:30”,“city”:”\u676d\u5dde”,“cityEn”:“hangzhou”,“country”:”\u4e2d\u56fd”,“countryEn”:“China”,“wea”:”\u6674″,“wea_img”:“qing”,“tem”:“10”,“tem1”:“14”,“tem2”:“7”,“win”:”\u4e1c\u98ce”,“win_speed”:“3\u7ea7”,“win_meter”:”\u5c0f\u4e8e12km/h”,“humidity”:“64%”,“visibility”:“13.6km”,“pressure”:“1021”,“air”:“48”,“air_pm25”:“48”,“air_level”:”\u4f18″,“air_tips”:”\u7a7a\u6c14\u5f88\u597d\uff0c\u53ef\u4ee5\u5916\u51fa\u6d3b\u52a8\uff0c\u547c\u5438\u65b0\u9c9c\u7a7a\u6c14\uff0c\u62e5\u62b1\u5927\u81ea\u7136\uff01″,“alarm”:{“alarm_type”:”\u5927\u98ce”,“alarm_level”:”\u9ec4\u8272″,“alarm_content”:”\u676d\u5dde\u5e02\u6c14\u8c61\u53f02021\u5e7402\u670822\u65e517\u65f635\u5206\u53d1\u5e03\u5927\u98ce\u9ec4\u8272\u9884\u8b66\u4fe1\u53f7\uff1a\u53d7\u51b7\u7a7a\u6c14\u5f71\u54cd\uff0c\u4eca\u5929\uff0822\u65e5\uff09\u508d\u665a\u5230\u660e\u5929\uff0823\u65e5\uff09\u4e0b\u5348\u4e3b\u57ce\u533a\u548c\u94b1\u5858\u65b0\u533a\u6700\u5927\u504f\u5317\u98ce\u529b\u53ef\u8fbe57\u7ea7\uff0c\u5c71\u533a\u548c\u90e8\u5206\u6c5f\u6e56\u6c34\u976268\u7ea7\uff0c\u8bf7\u6709\u5173\u65b9\u9762\u6ce8\u610f\u3002\uff08\u9884\u8b66\u4fe1\u606f\u6765\u6e90\uff1a\u56fd\u5bb6\u9884\u8b66\u4fe1\u606f\u53d1\u5e03\u4e2d\u5fc3\uff09″},“aqi”:{“update_time”:“09:23”,“cityid”:“101210101”,“city”:”\u676d\u5dde”,“cityEn”:“hangzhou”,“country”:”\u4e2d\u56fd”,“countryEn”:“China”,“air”:“52”,“air_level”:”\u826f”,“air_tips”:”\u7a7a\u6c14\u597d\uff0c\u53ef\u4ee5\u5916\u51fa\u6d3b\u52a8\uff0c\u9664\u6781\u5c11\u6570\u5bf9\u6c61\u67d3\u7269\u7279\u522b\u654f\u611f\u7684\u4eba\u7fa4\u4ee5\u5916\uff0c\u5bf9\u516c\u4f17\u6ca1\u6709\u5371\u5bb3\uff01″,“pm25”:“20”,“pm25_desc”:”\u4f18″,“pm10”:“53”,“pm10_desc”:”\u826f”,“o3”:“42”,“o3_desc”:”\u4f18″,“no2”:“30”,“no2_desc”:”\u4f18″,“so2”:“5”,“so2_desc”:”\u4f18″,“co”:“1”,“co_desc”:”\u4f18″,“kouzhao”:”\u4e0d\u7528\u4f69\u6234\u53e3\u7f69″,“yundong”:”\u9002\u5b9c\u8fd0\u52a8″,“waichu”:”\u9002\u5b9c\u5916\u51fa”,“kaichuang”:”\u9002\u5b9c\u5f00\u7a97″,“jinghuaqi”:”\u5173\u95ed\u51c0\u5316\u5668″}}
