Question

我正在尝试了解如何调用API（Pokeapi）并将响应中收到的数据解析为C＃中外部库（PokeApi.NET）中的对象。

我在C＃代码中收到回复，但是我很难将响应解析为对象。

我认为问题在于最后一行代码，但我不确定它应该是什么？

C＃代码：

private static string URL = "http://pokeapi.co/api/v2/pokemon/";

static async void GetPokemonAsync()
{
    string page = URL;

    using (HttpClient client = new HttpClient())
    using (HttpResponseMessage response = await client.GetAsync(page))
    using (HttpContent content = response.Content)
    {
        string result = await content.ReadAsStringAsync();

        if (result != null && result.Length >= 50)
        {
            Console.WriteLine(result.Substring(0,200));
            PokeAPI.Pokemon a = JsonConvert.DeserializeObject<PokeAPI.Pokemon>(result);
        }
    }
}

结果示例：

{"count":811,"previous":null,"results":[{"url":"http:\/\/pokeapi.co\/api\/v2\/pokemon\/1\/","name":"bulbasaur"},{"url":"http:\/\/pokeapi.co\/api\/v2\/pokemon\/2\/","name":"ivysaur"},{"url":"http:\/\/pokeapi.co\/api\/v2\/pokemon\/3\/","name":"venusaur"},{"url":"http:\/\/pokeapi.co\/api\/v2\/pokemon\/4\/","name":"charmander"},{"url":"http:\/\/pokeapi.co\/api\/v2\/pokemon\/5\/","name":"charmeleon"},{"url":"http:\/\/pokeapi.co\/api\/v2\/pokemon\/6\/","name":"charizard"},...

Answer 1

这应该是你的班级结构。

    import javax.swing.JOptionPane;
    import java.util.Arrays;

    public class RainfallApp {

    public static void main(String[] args) {

    int[][] rain = new int[4][7];
    int[] average = new int[4];



    Rainfall r = new Rainfall();

    r.setRain(rain);
    r.compute();
    average = r.getAverage();

    JOptionPane.showMessageDialog(null, "The average for each week is: "+Arrays.toString(average));

}

这必须是有效的json。

public class Result
{
    public string url { get; set; }
    public string name { get; set; }
}

public class Pokemon
{
    public int count { get; set; }
    public object previous { get; set; }
    public List<Result> results { get; set; }
}

使用Newtonsoft软件包，您可以像此示例一样反序列化您的JSON。还可以使用json2sharp工具从JSON生成C#类。

如果在Visual Studio中有Web Essentials，则可以随时使用

修改＆gt;粘贴特殊＆gt;将JSON粘贴为类。

public class Result
{
    public string url { get; set; }
    public string name { get; set; }
}

public class RootObject
{
    public int count { get; set; }
    public object previous { get; set; }
    public List<Result> results { get; set; }
}

var  results = JsonConvert.DeserializeObject<RootObject>(json);

从Pokeapi解析JSON
