【Unity3D日常】獲取天氣信息以及地方位置

一、前言

前段時間有小夥伴問到如何用Unity製作天氣預報，博主也是在網上找了很多資料，發現天氣API接口穩定的確實沒有，除非是天氣官方提供的，但是我觀察了下，要是合作伙伴纔有開放的可能。

其他的，例如：百度 APIStore、一些同學在其他網站上抓包下來的接口，以及什麼各種收費的 API，都沒有穩定的。
找了很多接口API，發現了一個比較好用的免費天氣API，就分享一下

首先看一下效果圖：

二、參考資料

1、unity 獲取地方位置和天氣（簡單版本）
2、免費、穩定的天氣預報API
3、免費天氣API，天氣JSON API，不限次數獲取十五天的天氣預報
 4、國內天氣API Java版本請求Demo

三、正文

3.1 獲取地方位置

百度地圖API：

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

返回的Json字符串：

{“address”:“CN|\u6cb3\u5357|\u90d1\u5dde|None|UNICOM|0|0”,“content”:{“address”:"\u6cb3\u5357\u7701\u90d1\u5dde\u5e02",“address_detail”:{“city”:"\u90d1\u5dde\u5e02",“city_code”:268,“district”:"",“province”:"\u6cb3\u5357\u7701",“street”:"",“street_number”:""},“point”:{“x”:“185.64964385”,“y”:“134.75661006”}},“status”:0}

看不懂沒關係，我們去Json解析網站解析一下：
https://tool.oschina.net/codeformat/json

數據說明：
address：數據頭
content：數據內容

address：省份城市
address_detail：城市名字，編號代碼，省份
point：位置座標等數據

status：數據狀態

我們就根據這些數據寫一個數據類來接收這些數據：

#region 返回的城市名字等數據類
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

這些命名不能改，不然Json解析不了

下面解析Json文件

需要導入這些腳本：

    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

public class WeatherTools : MonoBehaviour
{
    /// <summary>
    /// 獲取位置信息
    /// </summary>
    string Posurl = "http://api.map.baidu.com/location/ip?ak=bretF4dm6W5gqjQAXuvP0NXW6FeesRXb&coor=bd09ll";

    void Start()
    {
        //獲取位置
        StartCoroutine(RequestCityName());
    }

    IEnumerator RequestCityName()
    {
        WWW www = new WWW(Posurl);
        yield return www;
        if (string.IsNullOrEmpty(www.error))
        {
            CityData cityData = LitJson.JsonMapper.ToObject<CityData>(www.text);
            Debug.Log(cityData.content.address_detail.city);
        }
    }
}

效果：

3.2 城市名字轉化爲城市代碼編號

因爲接口：

http://t.weather.sojson.com/api/weather/city/city_code

需要用到city_code的值，我們需要將獲取到城市名字轉爲city_code，也就是城市代碼編號，這個編號對應的Json文件是這樣的：

城市對應的city_code的Json文件：

城市名字轉爲city_code

3.3 獲取天氣信息

萬事俱備，只欠東風，接下來就看一下如何獲取天氣信息吧：

先分析一下獲取到Json字符串：
獲取天氣的API：

http://t.weather.sojson.com/api/weather/city/city_code

密密麻麻的啥玩意呀，沒關係，我們還可以用Json解析工具解析一下：
https://tool.oschina.net/codeformat/json

沒錯啦，就是我們需要的所有數據，我們根據這些再次製作數據類：

#region 天氣數據類
public class WeatherData
{
    public string message;
    public int status;
    public string date;
    public string time;
    public CityInfo cityInfo;
    public WeathData data;
}
public class CityInfo
{
    public string city;
    public string cityId;
    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[] forecast;
    public WeathDetailData yesterday;
}
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;
}
#endregion

看不懂建議再看一下Json解析出來的數據格式。。。
