Question

我在API上运行了一些本地测试，由于某种原因，数据XML数据没有进入API。 rData.labelDetail作为null提交给API。

看起来好像我使用了错误的ContentType，但我已经尝试过application / xml和text / xml但没有成功。

请求：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Net;
using System.IO;
using System.Text;

public partial class TestAPI : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        WebRequest request = WebRequest.Create("http://localhost:56146/Packages.svc/auth");
        request.Method = "POST";
        string postData = "<?xml version='1.0' encoding='UTF-8'?><RequestData xmlns='http://www.labels.com/label'><details>Test|Second Part</details></RequestData>";
        byte[] byteArray = Encoding.UTF8.GetBytes(postData);
        request.ContentType = "application/xml";
        request.ContentLength = byteArray.Length;

        Stream dataStream = request.GetRequestStream();
        dataStream.Write(byteArray, 0, byteArray.Length);
        dataStream.Close();
        WebResponse response = request.GetResponse();
        Console.WriteLine(((HttpWebResponse)response).StatusDescription);
        dataStream = response.GetResponseStream();
        StreamReader reader = new StreamReader(dataStream);
        string responseFromServer = reader.ReadToEnd();
        Console.WriteLine(responseFromServer);
        reader.Close();
        dataStream.Close();
        response.Close();
    }
}

    // NOTE: In order to launch WCF Test Client for testing this service, please select Packages.svc or Packages.svc.cs at the Solution Explorer and start debugging.
    public class Packages : IPackages
    {
        #region

        public ResponseData Auth(RequestData rData)
        {
            var data = rData.labelDetail.Split('|'); //Keep getting error here
            var response = new ResponseData
            {
                Name = data[0],
                PackageID = data[1]
            };

            return response;
        }

        #endregion
    }

    [DataContract(Namespace = "http://www.labels.com/label")]
    public class RequestData
    {
        [DataMember]
        public string labelDetail { get; set; }
    }

    [DataContract]
    public class ResponseData
    {
        [DataMember]
        public string Name { get; set; }

        [DataMember]
        public string PackageID { get; set; }
    }

}

您的元素名称不匹配。在XML请求中，根元素RequestData具有名为details的嵌套元素：

    string postData = "<?xml version='1.0' encoding='UTF-8'?><RequestData xmlns='http://www.labels.com/label'><details>Test|Second Part</details></RequestData>";

但是在您的数据合同中，相应的属性名为labelDetail：

[DataContract(Namespace = "http://www.labels.com/label")]
public class RequestData
{
    [DataMember] // Notice that "Name" is not set
    public string labelDetail { get; set; }
}

您需要使名称匹配，例如：

    [DataMember(Name="details")] 
    public string labelDetail { get; set; }

XML未传递给WCF
