MVC and Consuming Web Services Reference - SOAP

Question

User1391845369 posted

I have bee working with .NET MVC and C# for about a year now so I am a little green and need of some guidance on a project. 

So I currently have a .NET C# MVC project and within that project I have created a a Service Reference  to following service NemsisPmWsPort:

https://perfmeasures.nemsis.org/perfMeasureWs.wsdl

It created proxy reference to all the methods. 

At this point I am totally in the dark on how to write C# code in MVC to get a handle on the data.

There is a technical guide posted at this location and it gives the Request  parameters Response:

https://nemsis.org/wp-content/uploads/2019/06/NEMSISV3PerformanceMeasureServiceTechnicalGuide.pdf

Example:

The service also supports segmentation of performance measure data (analogous to the “group by” clause in an SQL query). To request the benchmark results to be segmented by a parameter, use the RetrieveBenchmark request with one <segment> element. The following example demonstrates a request for benchmark data for the Trauma-01 measure segmented (or grouped) by Urbanicity:

The request:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ws="http://ws.nemsis.org/">   
<soapenv:Header/>   
<soapenv:Body>     
<ws:RetrieveBenchmarkRequest>       
<ws:benchmark id="Trauma-01">         
<ws:segment>Urbanicity</ws:segment>       
</ws:benchmark>     
</ws:RetrieveBenchmarkRequest>   
</soapenv:Body> 
</soapenv:Envelope>

The service will return a message that contains segmented benchmark data providing a result for each member of the Urbanicity parameter:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:xs="http://www.w3.org/2001/XMLSchema"

</ns2:result>         
<ns2:result records="71126" segmentMember="P01004">

</ns2:result>         
<ns2:result records="147148" segmentMember="P01005">           
<ns2:numerator>80869</ns2:numerator>           
<ns2:denominator>147148</ns2:denominator>         
</ns2:result>       
</ns2:data>     
</ns2:RetrieveBenchmarkResponse>   
</SOAP-ENV:Body> 
</SOAP-ENV:Envelope>

A request may include zero or more <filter> elements and zero or one <segment> element.

Hi steven0608,

It created proxy reference to all the methods. 

Did you created proxy reference by Add Service Reference?

If so,I test according to your link. Since I don't have permission, I can't completely reproduce your problem. You could refer to my code:

ServiceReference1.NemsisPmWsPortClient re = new ServiceReference1.NemsisPmWsPortClient();

            re.RetrieveBenchmark(new ServiceReference1.RetrieveBenchmarkRequest() {
                benchmark = new ServiceReference1.BenchmarkRequest() {
                    filter = new ServiceReference1.Filter[1] {new ServiceReference1.Filter { parameter = "P01001", Value = "201712" } } } }  );

Best Regards.

Yes, I created the proxy reference to all the methods.  Since I am kind of new to C# I was unsure on what to from this point.

I believe all this data is public, it should not require any credentials to pull the national data.  I am going to create a new controller and view and test out your code to see where that gets me.

I am still a little lost on what your code does and how you determined what direction you went?  Can you explain your code please?

Two other questions that involve this same method because I am trying to figure out how you know what syntax and calls to make:

So how would I make this request using C# and the reference classes and methods and get the correct response back?

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ws="http://ws.nemsis.org/">   
<soapenv:Header/>   <soapenv:Body>     
<ws:ListBenchmarksRequest/>   
</soapenv:Body> 
</soapenv:Envelope>

This response should be:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">   
<SOAP-ENV:Header/>   
<SOAP-ENV:Body>     
<ns2:ListBenchmarksResponse xmlns:ns2="http://ws.nemsis.org/">       
<ns2:benchmark id="Trauma-01" numeratorType="xs:nonNegativeInteger" denominatorType="xs:nonNegativeInteger">Pain Assessment of Injured Patients</ns2:benchmark>       
<ns2:benchmark id="Seizure-01" numeratorType="xs:nonNegativeInteger" denominatorType="xs:nonNegativeInteger">Blood Glucose Evaluation</ns2:benchmark>
<ns2:benchmark id="Stroke-01" numeratorType="xs:nonNegativeInteger" denominatorType="xs:nonNegativeInteger">Suspected Stroke Receiving Prehospital Stroke Assessment</ns2:benchmark>     
</ns2:ListBenchmarksResponse>   
</SOAP-ENV:Body> 
</SOAP-ENV:Envelope> 

I would also like to return these values to a view.  How would I go about doing that as well?

So after looking at your code and taking stab after stab I came up with this code to grab the "Truama-01" data in my NEMSISmeasuresWSRController.cs

Now I have to pull the retrieve the response and display then display the <numerator>69523</numerator>
<denominator>128505</denominator>  into a view.   Some help we be much appreciated.

    {
        // GET: NEMSISmeasuresWSR
        public ActionResult Index()
        {
    
            using (var client = new NemsisPmWsPort.NemsisPmWsPortClient())
            {
                
                var request = new NemsisPmWsPort.RetrieveBenchmarkRequest();
                request.benchmark = new NemsisPmWsPort.BenchmarkRequest();
                request.benchmark.id = "Trauma-01";
                request.benchmark.filter = new NemsisPmWsPort.Filter[] {
                    new NemsisPmWsPort.Filter { parameter = "Urbanicity", Value = "P01001" },
                    new NemsisPmWsPort.Filter { parameter = "CalendarMonth", Value = "201712" }                    
                };
                var response = client.RetrieveBenchmark(request);

            }
            
           //Not returning anything yet. I will need to user the RetriveBenchmarkResponse mehtod to retrieve my data response from the service.
            return View("Home");
