A collection script for weather history data

Recently a project needs to use the past weather data, I found the weather after the site (www.tianqihoubao.com), and in the SS completed the relevant collection, and share with you.

The first analysis of this site provides two types of information:

1. Provincial and municipal relations

2. Weather Records

Corresponding to our create data structure:

[Serializable]
public class province
{public
    string provincename;
    public string Provinceurl;
}
    
[Serializable]
public class city
{public
    province province;
    public string CityName;
    public string Cityurl;
}
    
[Serializable]
public class Weatherdataset
{public City
    ;
    public string Title;
    public string Url;
    
[Serializable]
public class Weatherdata
{public
    weatherdataset DataSet;
    public string Date;
    public string Textweather;
    public string Temp;
    public string Wind;
}
