九、附：一些免费、稳定的天气预报 API 的资源参考学习

1. 国家气象局

2. 中国天气SmartWeatherAPI(http://smart.weather.com.cn/wzfw/smart/weatherapi.shtml)

3. 和风天气

4. 心知天气（免费版只提供地级市数据）

5. 彩云天气

6. 中央天气预报

一、简单介绍

Unity 工具类，自己整理的一些游戏开发可能用到的模块，单独独立使用，方便游戏开发。

本届介绍获取所在城市的天气数据，并且封装成数据接口，只要设置一个监听数据接口，即可调用。

二、实现原理

1、首先根据联网 IP 获得当前所在城市，使用百度的web API；

2、然后根据城市名称得到天气所需要的城市ID；

3、根据城市ID，最后得到天气数据，解析封装给接口调用；

三、注意实现

1、需要在百度地图开发者平台上申请一个 ak，API 和 ak 共同组成接口，获得位置 json 解析数据

2、使用时候需要连接网络

3、接口目前好似只能获得国内的城市天气数据

四、效果预览

五、实现步骤

百度地图申请 ak：

1、登录百度地图开发者中心，需要一个百度账号，自行注册申请即可

网址：http://lbsyun.baidu.com/

2、开发文档，选择 Web服务API

3、获取密钥（AK 应用钥匙）

4、创建应用即可获得 AK ，也可以用之前创建的（根据需要）

5、在Web服务API 普通 IP 定位中，可以看到相关使用文档，API 接口，以及返回 json 格式，等

注意：API 和 ak 共同组成接口，获得 json 解析数据

Unity上实现：

1、打开Unity，新建一个空工程，导入LitJson 插件

2、在场景中布局UI，展示一些天气数据

3、新建几个脚本，其中几个脚本定义一些数据结构（PositionDataStruct，WeatherDataStruct），GetWeatherWrapper 主要实现定位当前城市，和获取天气数据，TestGetWeatherWrapper 测试 GetWeatherWrapper 的接口，并展示一些天气数据

4、运行场景，效果如下

六、关键代码

1、PositionDataStruct

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class PositionDataStruct
{public class ResponseBody{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 Address_Detail(){}public Address_Detail(string city, int city_code, string district, string province, string street, string street_number){this.city = city;this.city_code = city_code;this.district = district;this.province = province;this.street = street;this.street_number = street_number;}}public class Point{public string x;public string y;public Point(){}public Point(string x, string y){this.x = x;this.y = y;}}}

2、WeatherDataStruct

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class WeatherDataStruct
{public static Dictionary<string, int> PosToId = new Dictionary<string, int>();public static bool initDic = false;public const string WeatherCityId = "WeatherCityId";public static int GetWeatherId(string name){int id = 0;if(!initDic){initDic = true;TextAsset ta = Resources.Load<TextAsset>(WeatherCityId);List<Pos2Id> temp = LitJson.JsonMapper.ToObject<List<Pos2Id>>(ta.text);foreach(Pos2Id t in temp){PosToId[t.placeName] = t.id;}}for(int i=1;i<name.Length;i++){string tn = name.Substring(0, i);if(PosToId.ContainsKey(tn)){id = PosToId[tn];}}return id;}public class Pos2Id{public string placeName;public int id;public Pos2Id(){}public Pos2Id(string name,int id){placeName = name;this.id = id;}}public class WeathBody{public string time;public CityInfo cityInfo;public string date;public string message;public int status;public WeathData data;}public class CityInfo{public string city;public string citykey;public string parent;public string updateTime;}public class WeathData{public string shidu;public double pm25;public double pm10;public string quality;public string wendu;public string ganmao;public WeathDetailData yesterday;public WeathDetailData[] forecast;}public class WeathDetailData{public string date;public string sunrise;public string high;public string low;public string sunset;public double aqi;public string ymd;public string week;public string fx;public string fl;public string type;public string notice;}}

3、GetWeatherWrapper

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;/// <summary>
/// 获取对应城市的天气
/// 注意：温度时摄氏度°C
/// </summary>
public class GetWeatherWrapper : MonoSingleton<GetWeatherWrapper>

}

4、TestGetWeatherWrapper

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;public class TestGetWeatherWrapper : MonoBehaviour
{public Text City_Text;public Text WeatherDec_Text;public Text Temperature_Text;public Text WeatherTime_Text;public Text WeatherNotice_Text;// Start is called before the first frame updatevoid Start(){ShowWeather();}void ShowWeather() {GetWeatherWrapper.Instance.SetWeatherDataEvent((weatherData)=> {City_Text.text = weatherData.cityInfo.city;WeatherTime_Text.text = weatherData.date;WeatherDec_Text.text = weatherData.data.forecast[0].type;Temperature_Text.text = weatherData.data.forecast[0].low +"°C"+ "~" + weatherData.data.forecast[0].high + "°C";WeatherNotice_Text.text = weatherData.data.forecast[0].notice;});}

}

详细接口分析如下：

//格式说明
var format={"fa":图片1,"fb"：图片2,"fc":温度1,fd：温度2,fe:风向1,ff：风向2,fg:风力1,fh：风力2,fi:日出日落};
//定义天气类型
var weatherArr={"10": "暴雨", "11": "大暴雨", "12": "特大暴雨", "13": "阵雪", "14": "小雪", "15": "中雪", "16": "大雪", "17": "暴雪", "18": "雾", "19": "冻雨", "20": "沙尘暴", "21": "小到中雨", "22": "中到大雨", "23": "大到暴雨", "24": "暴雨到大暴雨", "25": "大暴雨到特大暴雨", "26": "小到中雪", "27": "中到大雪", "28": "大到暴雪", "29": "浮尘", "30": "扬沙", "31": "强沙尘暴", "53": "霾", "99": "", "00": "晴", "01": "多云", "02": "阴", "03": "阵雨", "04": "雷阵雨", "05": "雷阵雨伴有冰雹", "06": "雨夹雪", "07": "小雨", "08": "中雨", "09": "大雨"

};

3）获取全国所有城市代码列表

方法一：XML接口根节点： http://flash.weather.com.cn/wmaps/xml/china.xmlXML接口主要作用是递归获取全国几千个县以上单位的城市代码，如：江苏的XML地址为：http://flash.weather.com.cn/wmaps/xml/shanghai.xml

苏州的XML地址为：http://flash.weather.com.cn/wmaps/xml/jiangsu.xml

上面页面获得太仓city code：101190408合成太仓天气信息地址：http://m.weather.com.cn/data/101190408.html

下面贴一段PHP代码实现的，通过XML接口根节点递归获得全国几千个县以上城市cide code的代码，供参考(可直接在终端下运行）：

方法二：一次性获取全国+国外主要城市，8763个城市列表信息。URL：http://mobile.weather.com.cn/js/citylist.xml
