ASP.NET Core - 反序列化城市 API XML 响应不起作用

Question

调用城市 API 时，它以 XML 格式返回此响应。我想将此 XML 反序列化为一个对象。反序列化抓取对象，直到 diffgram 内的 diffgram 我们有

NewDataSet

属性，该属性返回 null，我需要获取 Cities。

API响应：

<?xml version="1.0" encoding="UTF-8"?>

             </getRTLCitiesResult>

代码详情：

 [XmlRoot(ElementName = "RetailCities")]
 public class RetailCity
 {
     [XmlElement(ElementName = "routCode")]
     public string RoutCode { get; set; }

     [XmlElement(ElementName = "rCity")]
     public string RCity { get; set; }
 }

 [XmlRoot(ElementName = "NewDataSet")]
 public class NewDataSet
 {
     [XmlElement(ElementName = "RetailCities")]
     public List<RetailCity> RetailCities { get; set; } = new List<RetailCity>();
 }

 [XmlRoot(ElementName = "diffgram", Namespace = "urn:schemas-microsoft-com:xml-diffgram-v1")]
 public class Diffgram
 {
     [XmlElement(ElementName = "NewDataSet")]
     public NewDataSet NewDataSet { get; set; }
 }

 [XmlRoot(ElementName = "getRTLCitiesResult", Namespace = "http://track.smsaexpress.com/secom/")]
 public class GetRTLCitiesResult
 {
     [XmlElement(ElementName = "diffgram", Namespace = "urn:schemas-microsoft-com:xml-diffgram-v1")]
     public Diffgram Diffgram { get; set; }
 }

 [XmlRoot(ElementName = "getRTLCitiesResponse", Namespace = "http://track.smsaexpress.com/secom/")]
 public class GetRTLCitiesResponse
 {
     [XmlElement(ElementName = "getRTLCitiesResult")]
     public GetRTLCitiesResult GetRTLCitiesResult { get; set; }
 }

 [XmlRoot(ElementName = "Body", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
 public class SoapBody
 {
     [XmlElement(ElementName = "getRTLCitiesResponse", Namespace = "http://track.smsaexpress.com/secom/")]
     public GetRTLCitiesResponse GetRTLCitiesResponse { get; set; }
 }

 [XmlRoot(ElementName = "Envelope", Namespace = "http://schemas.xmlsoap.org/soap/envelope/")]
 public class SoapEnvelope
 {
     [XmlElement(ElementName = "Body")]
     public SoapBody Body { get; set; }

     [XmlNamespaceDeclarations]
     public XmlSerializerNamespaces Xmlns { get; set; } = new XmlSerializerNamespaces();

     public SoapEnvelope()
     {
         Xmlns.Add("soap", "http://schemas.xmlsoap.org/soap/envelope/");
         Xmlns.Add("xsi", "http://www.w3.org/2001/XMLSchema-instance");
         Xmlns.Add("xsd", "http://www.w3.org/2001/XMLSchema");
     }
 }


  private static T DeserializeXml<T>(string xml)
  {
      XmlSerializer serializer = new XmlSerializer(typeof(T));
      using (StringReader reader = new StringReader(xml))
      {
          return (T)serializer.Deserialize(reader)!;
      }
  }

调用API并反序列化XML响应：

using (var client = new HttpClient())
{
    var content = new StringContent(AramexCitiesSoapEnvelope(), Encoding.UTF8, "text/xml");

    try
    {
        var response = await client.PostAsync(endPoint, content);

        if (response.IsSuccessStatusCode)
        {
            // Read and return the response content
            var resultContent = await response.Content.ReadAsStringAsync();                 
            var envelope = DeserializeXml<SoapEnvelope>(resultContent);

            return envelope;
        }
        else
        {
            // Return the failed response content
            var errorContent = await response.Content.ReadAsStringAsync();
            return new SoapEnvelope() { ErrorMessage = errorContent };
        }
    }
    catch (HttpRequestException e)
    {
        return new SoapEnvelope() { ErrorMessage = e.Message };
    }
}

输出：

我创建了模型类，并使用

XmlElement

注释装饰这些模型，以反序列化 XML 响应以获取位于

RetailCities

列表内的城市名称。不过，不幸的是，我无法到达

RetailCities

，因为

NewDataSet

返回 null。

Answer 1

在 XML

<NewDataSet xmlns="">

中，您应该在

Namespace = ""

类中

XmlElement

属性的

NewDataSet

属性中添加

Diffgram

。

[XmlRoot(ElementName = "diffgram", Namespace = "urn:schemas-microsoft-com:xml-diffgram-v1")]
public class Diffgram
{
    [XmlElement(ElementName = "NewDataSet", Namespace = "")]
    public NewDataSet NewDataSet { get; set; }
}
