SOAP Web Service (HTTP POST)

Demonstrates how to call PostXml to call a SOAP web service. Objective-C

#import <CkoXml.h>
#import <NSString.h>
#import <CkoHttp.h>
#import <CkoHttpResponse.h>

BOOL success = NO;

//  This example requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

//  --------------------------------------------------------------------------------
//  Also see Chilkat's Online WSDL Code Generator
//  to generate code and SOAP Request and Response XML for each operation in a WSDL.
//  --------------------------------------------------------------------------------

//  This example uses a live web service at:
//  http://www.webservicex.net/uklocation.asmx
//  It gets the UK town,Postcode and County by Postcode(First Section of Post Code)

//  The SOAP XML will look like this:
//  <?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>
//      <GetUKLocationByPostCode xmlns="http://www.webserviceX.NET">
//        <PostCode>string</PostCode>
//      </GetUKLocationByPostCode>
//    </soap:Body>
//  </soap:Envelope>

//  For this example's sake, we'll load the XML from a file.  We'll test using PostCode "E3".  
//  The SOAP XML for this example may be downloaded from:
//  http://www.chilkatsoft.com/testData/ukPostCodeSoap.xml
CkoXml *xml = [[CkoXml alloc] init];
success = [xml LoadXmlFile: @"ukPostCodeSoap.xml"];
if (success == NO) {
    NSLog(@"%@",xml.LastErrorText);
    return;
}

NSString *strXml = [xml GetXml];

int responseStatusCode;
CkoHttp *http = [[CkoHttp alloc] init];

//  We'll need to add this in the HTTP header:
//  SOAPAction: "http://www.webserviceX.NET/GetUKLocationByPostCode"
[http SetRequestHeader: @"SOAPAction" value: @"http://www.webserviceX.NET/GetUKLocationByPostCode"];

//  The endpoint for this soap service is:
NSString *endPoint = @"http://www.webservicex.net/uklocation.asmx";

//  Note: This particular web service was live and functioning at the time this example
//  was written.  It is possible that as time progresses, this web service will no longer
//  be availble...
CkoHttpResponse *resp = [[CkoHttpResponse alloc] init];
success = [http HttpStr: @"POST" url: endPoint bodyStr: strXml charset: @"utf-8" contentType: @"text/xml" response: resp];
if (success == NO) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

responseStatusCode = [resp.StatusCode intValue];
//  You may wish to verify that the responseStatusCode equals 200...
NSLog(@"%@%d",@"Response Status Code: ",responseStatusCode);

//  You may examine the exact HTTP header sent with the POST like this:
NSLog(@"%@",@"LastHeader:");
NSLog(@"%@",http.LastHeader);

//  Examine the XML returned by the web service:
NSLog(@"%@",@"XML Response:");
CkoXml *xmlResp = [[CkoXml alloc] init];
[xmlResp LoadXml: resp.BodyStr];
NSLog(@"%@",[xmlResp GetXml]);
