读取 coinbase api 时无法在 newtonsoft.Json.LinqJvalue 上获取 child 值？

Question

你好，我正在尝试从 URL 获取 coinbase API 汇率，但是 json.net 似乎无法格式化 JSON 文件以供读取children

这是抛出错误的方法

public string CalculateCoinValue(Coinbase connector)
{
    //bool valid = connector.rates.isValid;

    string cryptoExchangeRate;

    if (connector.rates != null)
    {
        cryptoExchangeRate = (string)connector.rates["data"]["currency"]["rates"][Settings.defualtCrypto.ToUpper()];

    }

    return "";
}

这是我用来获取 JSON 数据的方法，该数据将其存储在 Coinbase class

中的 JObject 中

public async Task<JObject> GetExchangeRatesAsync()
{

    HttpClient webClient = new HttpClient();
    string url = string.Format("https://api.coinbase.com/v2/exchange-rates?currency=" + Settings.defaultCurrency);
    HttpResponseMessage coinbaseJsonRaw = await webClient.GetAsync(url);
    return JObject.Parse(await coinbaseJsonRaw.Content.ReadAsStringAsync());
}

我做错了什么导致它不起作用？

Answer 1

返回的json看起来不一样。试试下面的

cryptoExchangeRate = (string)connector["data"]["rates"][Settings.defualtCrypto.ToUpper()];
