我怎么能通过HttpWebRequest调用wcf发送soaprequest [英] How could I call wcf by HttpWebRequest send soaprequest

问题描述

我只有.svc链接



我该怎么办才能调用wcf方法。

I only got the .svc link

what should i do to call wcf method.

HttpWebRequest myWebRequest = (HttpWebRequest)HttpWebRequest.Create("https://test.svc");
String xmlString =""
ASCIIEncoding encoding = new ASCIIEncoding();
byte[] bytesTowrite = encoding.GetBytes(xmlString);

myWebRequest.Method = "POST";
myWebRequest.ContentLength = bytesTowrite.Length;
myWebRequest.ContentType = "application/soap+xml; charset=utf-8";

Stream newStream = myWebRequest.GetRequestStream();
newStream.Write(bytesTowrite, 0, bytesTowrite.Length);
newStream.Close();

HttpWebResponse response = (HttpWebResponse)myWebRequest.GetResponse();
Stream datastream = response.GetResponseStream();
StreamReader reader = new StreamReader(datastream);

string responseFromServer = reader.ReadToEnd();

应该用xmlString写什么



谢谢，

推荐答案

您需要使用SOAP序列化。请参阅：

http：// msdn .microsoft.com / zh-CN / library / 90c86ass％28v = vs.110％29.aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/system.runtime .serialization.formatters.soap.soapformatter％28v = vs.110％29.aspx [ ^ ]。



但是，我不明白为什么你需要在如此低的水平上工作。如何使用服务合同，你甚至不使用数据，但立即使用接口及其方法？请参阅：

http：// msdn .microsoft.com / zh-CN / library / bb412196％28v = vs.110％29.aspx [ ^ ]。



在这种情况下，更多如果您需要，可以使用SOAP进行非常困难的工作。

You would need to use SOAP serialization. Please see:
http://msdn.microsoft.com/en-us/library/90c86ass%28v=vs.110%29.aspx[^],
http://msdn.microsoft.com/en-us/library/system.runtime.serialization.formatters.soap.soapformatter%28v=vs.110%29.aspx[^].

However, I don't understand why would you need to work at so low level. How about using Service Contract where you would work not even with the data, but immediately with the interface and its methods? Please see:
http://msdn.microsoft.com/en-us/library/bb412196%28v=vs.110%29.aspx[^].

In this case, more difficult work with SOAP you could leave to non-.NET client, if you even needed it.
