Read DynamicJsonArray with razor (mvc4 Umbraco)

Question

从https://demoapi.thismoment.com/v4.1/api/content读取Json

读取为流:

Stream stream = wc.OpenRead(url);
using (StreamReader reader = new StreamReader(stream))
{
String request = reader.ReadToEnd();
var requestJson = @Json.Decode(request);

和获取结果列表

var resultsList = new List<dynamic>(requestJson.results);

当试图读取下一层

时

var resultsList = new List<dynamic>(requestJson.results.media);

我得到这个错误:系统。

当我遍历列表

foreach (var item in resultsList)
{
<a>@item.media</a>
}

每个媒体项System.Web.Helpers.DynamicJsonArray.

我需要读取这个数组，这样我就可以得到每个图像的url和大小。

上面的json url是public的。我在Umbraco 7中做，它使用razor代码(aps mvc 4)。

您可以使用以下方法:

private static List<T> GetcollectionFromJason<T>(string jasonUrl) where T : new()
        {
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(jasonUrl);
            List<T> retCollection = new List<T>();
            try
            {
                WebResponse response = request.GetResponse();
                using (Stream responseStream = response.GetResponseStream())
                {
                    if (responseStream != null)
                    {
                        StreamReader reader = new StreamReader(responseStream, Encoding.UTF8);
                        string jsonString = reader.ReadToEnd();
                        JavaScriptSerializer serializer = new JavaScriptSerializer();
                        retCollection = serializer.Deserialize<List<T>>(jsonString);
                    }
                }
            }
            catch (WebException exp)
            {
                WebResponse errorResponse = exp.Response;
                using (Stream responseStream = errorResponse.GetResponseStream())
                {
                    if (responseStream != null)
                    {
                        StreamReader reader = new StreamReader(responseStream, Encoding.GetEncoding("utf-8"));
                        String errorText = reader.ReadToEnd();
                    }
                }
            }
            return retCollection;
        }

你可以这样命名它:

List<YourModel> technicalIssues = GetcollectionFromJason<YourModel>(YourJsonUrl);
