HttpClient

Pro větší kontrolu nad kódempřehledný kód, případně pro situace kdy nepoužíváte IDE které umožňuje automaticky generovat potřebný kód na základě WSDL definice, je možné využít třídy HttpClient, která je dostupná ve verzích:

Code Block
languagec#
// Prepare HttpClient
var client = new HttpClient();

// Define a new HTTP POST Request
var request = new HttpRequestMessage(HttpMethod.Post, "https://creditwebservices.creditcheck.cz/CreditCheckAktualizace.asmx");

// Add SOAPAction header to the Request
request.Headers.Add("SOAPAction", "https://creditwebservices.creditcheck.cz/GetSubjectFullReport");

// Add content to the Request
var content = new StringContent("<?xml version=\"1.0\" encoding=\"utf-8\"?>\n<soap:Envelope xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n    <soap:Header>\n        <CreditCheckHeader xmlns=\"https://creditwebservices.creditcheck.cz/\">\n            <Login>{login}</Login>\n            <Password>{password}</Password>\n        </CreditCheckHeader>\n    </soap:Header>\n    <soap:Body>\n        <GetSubjectFullReport xmlns=\"https://creditwebservices.creditcheck.cz/\">\n            <subjectData xmlns=\"https://creditwebservices.creditcheck.cz/\">\n                <requestSubject>\n                    <subjectType>Company</subjectType>\n                    <ic>00014915<<ic>{ico}</ic>\n                </requestSubject>\n            </subjectData>\n        </GetSubjectFullReport>\n    </soap:Body>\n</soap:Envelope>", null, "text/xml; charset=utf-8");
request.Content = content;

// Call Web service
var response = await client.SendAsync(request);
response.EnsureSuccessStatusCode();
Console.WriteLine(await response.Content.ReadAsStringAsync());

HttpWebRequest

Pro kompletní kontrolu nad odesílaným požadavkem, je možné využít třídy HttpWebRequest. Tento postup umožňuje definovat veškeré parametry odchozího Requestu. Bude funkční prakticky ve všech verzích .NET.

Code Block
languagec#
using System.Net;

// Set the SOAP endpoint URL
string url = "https://creditwebservices.creditcheck.cz/CreditCheckAktualizace.asmx";

// Construct the SOAP request body
string soapXml = @"<?xml version=""1.0"" encoding=""utf-8""?>
<soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
    <soap:Header>
        <CreditCheckHeader xmlns=""https://creditwebservices.creditcheck.cz/"">
            <Login>{login}</Login>
            <Password>{password}</Password>
        </CreditCheckHeader>
    </soap:Header>
    <soap:Body>
        <GetSubjectFullReport xmlns=""https://creditwebservices.creditcheck.cz/"">
            <subjectData xmlns=""https://creditwebservices.creditcheck.cz/"">
                <requestSubject>
                    <subjectType>Company</subjectType>
                    <ic>{ico}</ic>
                </requestSubject>
            </subjectData>
        </GetSubjectFullReport>
    </soap:Body>
</soap:Envelope>";

// Create the HTTP request
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "POST";
request.ContentType = "text/xml; charset=utf-8";

// Write the SOAP request to the request stream
using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
{
    writer.Write(soapXml);
}

// Get the response from the server
using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
{
    if (response.StatusCode == HttpStatusCode.OK)
    {
        using (StreamReader reader = new StreamReader(response.GetResponseStream()))
        {
            string responseXml = reader.ReadToEnd();
            // Process the SOAP response XML
            Console.WriteLine("SOAP Response:");
            Console.WriteLine(responseXml);
        }
    }
    else
    {
        Console.WriteLine("Error: " + response.StatusDescription);
    }
}

Service reference

Využijeme možností které nám nabízí IDE a necháme automaticky vygenerovat potřebné třídy a metody pro volání na základě WSDL definice ke které poskytnete URL (viz. výše).

...

Code Block
languagec#
using System.Xml;

// Prepare instance of SOAP client class (class is generated automatically based on WSDL)
Creditcheck_ServiceReference.CreditCheckAktualizaceSoapClient client =
    new Creditcheck_ServiceReference.CreditCheckAktualizaceSoapClient(Creditcheck_ServiceReference.CreditCheckAktualizaceSoapClient.EndpointConfiguration.CreditCheckAktualizaceSoap);

// Prepare instance of CreditCheckHeader
Creditcheck_ServiceReference.CreditCheckHeader ccHeader = new Creditcheck_ServiceReference.CreditCheckHeader();
ccHeader.Login = "{login}";
ccHeader.Password = "{password}";

// Call WS method GetCreditCheck
var getCreditChecksResult = await client.GetCreditChecksAsync(ccHeader);


// Define request parameters
string gsfrXmlRequest = @"
                <requestSubject>
                    <subjectType>Company</subjectType>
                    <ic>{ico}</ic>
                </requestSubject>";

XmlDocument xmlDocument = new XmlDocument();
xmlDocument.LoadXml(gsfrXmlRequest);

var// getCreditChecksResultCall =WS await client.GetCreditChecksAsync(ccHeader);method GetSubjectFullReport
var getSubjectFullReportResult = await client.GetSubjectFullReportAsync(ccHeader, xmlDocument);
