如何使用Json.NET从魔兽世界拍卖API中反序列化json数据

标签: c# json json.net deserialization world-of-warcraft

以下是API返回的json数据的示例片段:

{
"realm":{"name":"Molten Core","slug":"molten-core"},
"auctions":{"auctions":[
    {"auc":1880591075,"item":109128,"owner":"Leagra","ownerRealm":"Azjol-Nerub","bid":858600,"buyout":900000,"quantity":100,"timeLeft":"VERY_LONG","rand":0,"seed":0,"context":0},
    {"auc":1879726534,"item":43115,"owner":"Nêwt","ownerRealm":"Azjol-Nerub","bid":5120000,"buyout":5120000,"quantity":16,"timeLeft":"VERY_LONG","rand":0,"seed":835268864,"context":0}]}
}

(虽然很明显有真实的数据,但还有成千上万的拍卖。)

我希望对此进行反序列化,忽略领域数据,只是将拍卖放入一个干净的List<WowAuction>对象中,WowAuction为:

public class WowAuction
{
      public long auc { get; set; }
      public long item { get; set; }
      public long bid { get; set; }
      public long buyout { get; set; }
}

我无法理解如何做到这一点,API返回的json对我来说似乎相当混乱(尽管我承认以前我还没有和json合作过)。

据我所知,有一个名为&#34;拍卖&#34;的集合,其中一个字段也称为&#34;拍卖&#34;这是一个表,该表然后包含拍卖数据行。我该怎么反序化呢?

有很多方法可以做到,但简单的方法是创建一个与JSON结构相同的域对象:

public class WoWAuctionResponse {
    public WoWRealmInfo Realm {get; set;}
    public WoWAuctionsBody Auctions {get; set;}
}

public class WoWAuctionsBody {
   public List<WoWAuction> Auctions {get; set;}
}

// ...

JsonConvert.DeserializeObject<WoWAuctionResponse>(json);

延长@ slvnperron的答案。

首先,构建你的类。我建议使用像json2csharp这样的工具。

    public class Realm
    {
        public string name { get; set; }
        public string slug { get; set; }
    }

    public class Auction
    {
        public int auc { get; set; }
        public int item { get; set; }
        public string owner { get; set; }
        public string ownerRealm { get; set; }
        public int bid { get; set; }
        public int buyout { get; set; }
        public int quantity { get; set; }
        public string timeLeft { get; set; }
        public int rand { get; set; }
        public int seed { get; set; }
        public int context { get; set; }
    }

    public class Auctions
    {
        public List<Auction> auctions { get; set; }
    }

    public class RootObject
    {
        public Realm realm { get; set; }
        public Auctions auctions { get; set; }
    }

其次,解析你的json。我建议使用像Json.net这样的工具。你可以用nuget安装它。

    public static void Main()
    {
        string json = @"{here your json}";
        RootObject m = JsonConvert.DeserializeObject<RootObject>(json);
        Console.WriteLine(m.realm.name.Trim());
    }

这里我们的输出将是:

以这种方式建立您的域模型并反序列化您的数据。

internal class WowAuction
{

    [JsonProperty("realm")]
    public Realm Realm { get; set; }

    [JsonProperty("auctions")]
    public Auctions Auctions { get; set; }
}


internal class Realm
{

    [JsonProperty("name")]
    public string Name { get; set; }

    [JsonProperty("slug")]
    public string Slug { get; set; }
}

internal class Auctions
{

    [JsonProperty("auctions")]
    public Auction[] Auctions { get; set; }
}

internal class Auction
{

    [JsonProperty("auc")]
    public int Auc { get; set; }

    [JsonProperty("item")]
    public int Item { get; set; }

    [JsonProperty("owner")]
    public string Owner { get; set; }

    [JsonProperty("ownerRealm")]
    public string OwnerRealm { get; set; }

    [JsonProperty("bid")]
    public int Bid { get; set; }

    [JsonProperty("buyout")]
    public int Buyout { get; set; }

    [JsonProperty("quantity")]
    public int Quantity { get; set; }

    [JsonProperty("timeLeft")]
    public string TimeLeft { get; set; }

    [JsonProperty("rand")]
    public int Rand { get; set; }

    [JsonProperty("seed")]
    public int Seed { get; set; }

    [JsonProperty("context")]
    public int Context { get; set; }
}

稍后您可以使用以下语句对数据进行反序列化

JsonConvert.DeserializeObject<WowAuction>(data);

自从最初提出这个问题以来,事情发生了一些变化。 World of Warcraft APIs现在包括游戏数据和配置文件API。如此处其他答案所述,您可以创建模型类并使用Json.NET或类似的库来处理反序列化。还有Argent Pony Warcraft ClientBattleMuffin Blizzard API Client之类的NuGet程序包,它们已经定义了模型类并为您处理反序列化。

下面是一个ArgentPonyWarcraftClient NuGet包的示例。它显示了每次拍卖可用信息的子集。

string clientId = "CLIENT-ID-GOES-HERE";
string clientSecret = "CLIENT-SECRET-GOES-HERE";

int connectedRealmId = 1146;

IAuctionHouseApi warcraftClient = new WarcraftClient(
    clientId: clientId,
    clientSecret: clientSecret,
    region: Region.US,
    locale: Locale.en_US);

RequestResult<AuctionsIndex> result = await warcraftClient.GetAuctionsAsync(connectedRealmId, "dynamic-us");

if (result.Success)
{
    AuctionsIndex auctions = result.Value;

    foreach(Auction auction in auctions.Auctions)
    {
        Console.WriteLine($"{auction.Id}: Item ID: {auction.Item.Id} Quantity: {auction.Quantity}");
    }
}
