[英]C# SOAP Service without WCF
我正在嘗試使用CCF在不使用WCF工具的情況下創建SOAP Web服務和Web客戶端。 我的目標是創建一個與很可能沒有使用WCF的SOAP服務通信的客戶端。 我做了一個概念證明客戶端,但目前我還不確定如何編寫原始SOAP XML以發送到WCF服務來測試我的客戶端。 此外,即使SOAP服務不使用WCF,我可以在客戶端使用WCF嗎? 謝謝!
SOAP客戶端:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Xml;
using System.Net;
using System.Text;
using System.IO;
namespace HttpSoapPoc.Models
{
public class SoapClient
{
protected virtual WebRequest CreateRequest(ISoapMessage soapMessage)
{
var wr = WebRequest.Create(soapMessage.Uri);
wr.ContentType = "text/xml;charset=utf-8";
wr.ContentLength = soapMessage.ContentXml.Length;
wr.Headers.Add("SOAPAction", soapMessage.SoapAction);
wr.Credentials = soapMessage.Credentials;
wr.Method = "POST";
wr.GetRequestStream().Write(Encoding.UTF8.GetBytes(soapMessage.ContentXml), 0, soapMessage.ContentXml.Length);
return wr;
}
public interface ISoapMessage
{
string Uri { get; }
string ContentXml { get; }
string SoapAction { get; }
ICredentials Credentials { get; }
}
public static string CallWebService()
{
var _url = "https://passport.iso.com/PPWebListener/services/SOAPListenerV2";
var _action = "https://passport.iso.com/PPWebListener/services/SOAPListenerV2?op=HelloWorld";
XmlDocument soapEnvelopeXml = CreateSoapEnvelope();
HttpWebRequest webRequest = CreateWebRequest(_url, _action);
InsertSoapEnvelopeIntoWebRequest(soapEnvelopeXml, webRequest);
// begin async call to web request.
IAsyncResult asyncResult = webRequest.BeginGetResponse(null, null);
// suspend this thread until call is complete. You might want to
// do something usefull here like update your UI.
asyncResult.AsyncWaitHandle.WaitOne();
// get the response from the completed web request.
string soapResult;
using (WebResponse webResponse = webRequest.EndGetResponse(asyncResult))
{
using (StreamReader rd = new StreamReader(webResponse.GetResponseStream()))
{
soapResult = rd.ReadToEnd();
}
return soapResult;
}
}
private static HttpWebRequest CreateWebRequest(string url, string action)
{
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(url);
webRequest.Headers.Add("SOAPAction", action);
webRequest.ContentType = "text/xml;charset=\"utf-8\"";
webRequest.Accept = "text/xml";
webRequest.Method = "POST";
return webRequest;
}
private static XmlDocument CreateSoapEnvelope()
{
XmlDocument soapEnvelop = new XmlDocument();
String xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?>";
xml += "<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">";
xml += "<soap:Body>";
xml += "<CelsiusToFahrenheit xmlns=\"http://tempuri.org/\">";
xml += "<Celsius>20</Celsius>";
xml += "</CelsiusToFahrenheit>";
xml += "</soap:Body>";
xml += "</soap:Envelope>";
soapEnvelop.LoadXml(xml);
return soapEnvelop;
}
private static void InsertSoapEnvelopeIntoWebRequest(XmlDocument soapEnvelopeXml, HttpWebRequest webRequest)
{
using (Stream stream = webRequest.GetRequestStream())
{
soapEnvelopeXml.Save(stream);
}
}
}
}
SOAP服務:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
using System.ServiceModel.Activation;
namespace SoapTutorial
{
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
public class SoapService : ISoapService
{
public Employee[] GetEmployees()
{
return new Employee[]
{
new Employee() { EmpNo=101, EmpName="Mahesh", DeptName="CTD" },
new Employee() { EmpNo=102, EmpName="Akash", DeptName="HRD" }
};
}
}
}
您可以將WCF與basicHttpBinding一起使用。 這將創建一個非WCF客戶端可互操作的SOAP服務。
