在C＃中從JSON API反序列化HttpWebResponse

Question

我知道這些主題在stackoverflow上已經存在很多。 但是我有一點不同的問題：

我創建了一個DataContract類，如下所示：

    [DataContract]
  public class GLSParcelClass {
    internal string Location;
    internal string ConsignmentId;
    internal string Labels;
    internal List<Parcels> ParcelList;
    internal List<Returns> ReturnList;
  }

  [DataContract]
  public class Parcels {
    internal string Location;
    internal string TrackId;
    internal string ParcelNumber;
  }

  [DataContract]
  public class Returns {
    internal string Location;
    internal string TrackId;
    internal string ParcelNumber;
  }

然后，我編寫了以下函數：

      WebRequest httpWebRequest = WebRequest.Create(this.GLSUri);
  string json = "{" +
      "\"shipperId\":\"2764200001 276a165X14\"," +
      "\"references\":[\"47110815\"]," +
      "\"addresses\":{" +
        "\"delivery\":{" +
          "\"name1\":\"Max Meyer\"," +
          "\"name2\":\"Meyer Ltd.\"," +
          "\"street1\":\"Meyer Str. 227\"," +
          "\"street2\":\"2. Floor\"," +
          "\"country\":\"DE\"," +
          "\"zipCode\":\"92753\"," +
          "\"city\":\"Passau\"," +
          "\"email\":\"maxmeyer@gmail.com\"}}," +
      "\"parcels\":[" +
        "{" +
          "\"weight\":2.5," +
          "\"references\":[" +
            "\"47110815\"]" +
        "}" +
      "]" +
    "}";

  httpWebRequest.ContentType = "application/json";

  Type type = httpWebRequest.Headers.GetType();
  System.Reflection.BindingFlags flags = System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic;
  System.Reflection.MethodInfo m = type.GetMethod("AddWithoutValidate", flags);
  m.Invoke(httpWebRequest.Headers, new string[] { "Accept", "application/json" });
  m.Invoke(httpWebRequest.Headers, new string[] { "Accept-Language", "de" });
  m.Invoke(httpWebRequest.Headers, new string[] { "Accept-Encoding", "gzip,deflate" });

  httpWebRequest.Method = "POST";

  string lsEncodedCred = System.Convert.ToBase64String(System.Text.Encoding.GetEncoding("utf-8").GetBytes("shipmentsapi" + ":" + "shipmentsapi"));
  httpWebRequest.Headers.Add("Authorization", "Basic " + lsEncodedCred);
  httpWebRequest.PreAuthenticate = true;

  StreamWriter streamWriter = null;
  using (streamWriter = new StreamWriter(httpWebRequest.GetRequestStream())) {
    streamWriter.Write(json);
    streamWriter.Flush();
    streamWriter.Close();
  }

  HttpWebResponse httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();

  using (StreamReader loStream = new StreamReader(httpResponse.GetResponseStream())) {
    GLSParcelClass deserializedParcels = new GLSParcelClass();
    string lsJSON = loStream.ReadToEnd();
    MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(lsJSON));
    DataContractJsonSerializer ser = new DataContractJsonSerializer(deserializedParcels.GetType());
    deserializedParcels = ser.ReadObject(ms) as GLSParcelClass;
    ms.Close();
  }

我從響應標頭中的JSON API得到了狀態代碼為201的答案“已創建”。 到現在為止還挺好。 但是，當我獲得ResponseStream時，出現錯誤“ System.Runtime.Serialization.SerializationException-反序列化對象時出錯。意外的字符“。”。 。

替代方案我已經使用Mozilla REST客戶端對其進行了測試。 我將獲得具有正確響應流的正確標頭。

響應流還包括base64字符串編碼的pdf文檔。

我真的不知道出什么問題了，希望您能幫助我。

提前很多。

我只能夠在屏幕截圖中發布JSON響應的一小部分：

JSON響應部分

如果要在監視窗口中打開JSON快速查看，我只會收到“字符串不是JSON格式”的消息。
