C # implement SOAP to call WebService

I recently wrote an SOA service and started to think that someone else can get my service address and then add a reference directly to use it. The result "Daniel" tells me that it cannot be used.

Let me write a SOAP call service example. I am a little confused, because I have never done this, so I got a Demo and learned it.

 

Learn the following:

There is an object in. Net: WebRequest, which can directly request the service method in the background.

Step 1

var webRequest = (HttpWebRequest)WebRequest.Create(this.Uri);webRequest.Headers.Add("SOAPAction", String.Format("\"{0}\"", this.SoapAction));webRequest.ContentType = "text/xml;charset=\"utf-8\"";webRequest.Accept = "text/xml";webRequest.Method = "POST";webRequest.Credentials = this.Credentials;

A:In the above Code, there is a SOAPAction, which is to access the service after you deploy the service in IIS, such:

The figure tells the user: SOAPAction: "http://tempuri.org/ProcessFlowRequest"

B:WebRequest. Credentials = this. Credentials;

Is the credential for calling the service

Step 2

After reading the preceding information, You Need To splice the SOAP information in the xml of the soap request.

<?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>    <{0} xmlns='{1}'>{2}</{0}>  </soap:Body></soap:Envelope>

Replace the corresponding information in the image with the position {X}, and the information is spliced!

Step 3

Var webRequest = (HttpWebRequest) WebRequest. create (this. uri); webRequest. headers. add ("SOAPAction", String. format ("\" {0} \ "", this. soapAction); webRequest. contentType = "text/xml; charset = \" UTF-8 \ ""; webRequest. accept = "text/xml"; webRequest. method = "POST"; webRequest. credentials = this. credentials; // write the request SOAP information using (var requestStream = webRequest. getRequestStream () {using (var textWriter = new StreamWriter (requestStream) {var envelope = SoapHelper. makeEnvelope (this. soapAction, this. arguments. toArray () ;}/// get the SOAP request and return the return webRequest. getResponse ();

This will get the XML returned by the request!

 

It is actually easy to know when it is used!
