发送SOAP请求和接收响应的客户端
发送SOAP请求和接收响应的客户端
提问于 2011-01-25 17:32:23
尝试创建一个C#客户端(将作为Windows服务开发)，将SOAP请求发送到web服务(并获取结果)。
通过这个question，我看到了下面的代码：
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; }
}看起来不错，有人知道如何使用它吗?这是不是最好的做法？

我通常用另一种方法来做同样的事情。
using System.Xml;
using System.Net;
using System.IO;
public static void CallWebService()
{
var _url = "http://xxxxxxxxx/Service1.asmx";
var _action = "http://xxxxxxxx/Service1.asmx?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();
}
Console.Write(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 soapEnvelopeDocument = new XmlDocument();
soapEnvelopeDocument.LoadXml(
@"<SOAP-ENV:Envelope xmlns:SOAP-ENV=""http://schemas.xmlsoap.org/soap/envelope/""
xmlns:xsi=""http://www.w3.org/1999/XMLSchema-instance""
xmlns:xsd=""http://www.w3.org/1999/XMLSchema"">
<SOAP-ENV:Body>
<HelloWorld xmlns=""http://tempuri.org/""
SOAP-ENV:encodingStyle=""http://schemas.xmlsoap.org/soap/encoding/"">
<int1 xsi:type=""xsd:integer"">12</int1>
<int2 xsi:type=""xsd:integer"">32</int2>
</HelloWorld>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>");
return soapEnvelopeDocument;
}
private static void InsertSoapEnvelopeIntoWebRequest(XmlDocument soapEnvelopeXml, HttpWebRequest webRequest)
{
using (Stream stream = webRequest.GetRequestStream())
{
soapEnvelopeXml.Save(stream);
}

我认为有一种更简单的方法：
public async Task<string> CreateSoapEnvelope()
{
string soapString = @"<?xml version=""1.0"" encoding=""utf-8""?>
<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/"">
<soap:Body>
<HelloWorld xmlns=""http://tempuri.org/"" />
</soap:Body>
</soap:Envelope>";
HttpResponseMessage response = await PostXmlRequest("your_url_here", soapString);
string content = await response.Content.ReadAsStringAsync();
return content;
}
public static async Task<HttpResponseMessage> PostXmlRequest(string baseUrl, string xmlString)
{
using (var httpClient = new HttpClient())
{
var httpContent = new StringContent(xmlString, Encoding.UTF8, "text/xml");
httpContent.Headers.Add("SOAPAction", "http://tempuri.org/HelloWorld");
return await httpClient.PostAsync(baseUrl, httpContent);
}

最佳实践是引用WSDL并将其用作web服务引用。它更简单，效果也更好，但是如果您没有WSDL，XSD定义就是一段很好的代码。
