Calling a Web page using UHTTP

Author: (Colin)

Hi All, I have been asked to write a program that generates XML and then submits it to a website for processing. That process then returns the results to my program. I have no problem with generating the XML - it's easy using the UXMLWRITER facility. My problem is that I can't get the submit to work. Here is the example using LIBCURL I was given to base my code on The following is a cURL sample for DOS and may need slight modification for UNIX: REM sample curl call for Label Print Service curl -v -X POST -d@GenerateLabels.xml --header "Content-Type: application/soap+xml;charset=UTF-8;action=\"generateLabel\"" --insecure --user lps_merchant_dev:LabelDev123$ 2>out2.txt >out1.xml Here is my uniface code activate "UHTTP".SEND("", "POST", "userid", "password", "Content-Type:application/soap+xml;charset=UTF-8;action=%%"generatelabel%%"", v_xmlcode, v_response_header) My generated XML is in v_xmlcode. When I run this I get nothing. $status is 0. $procerror is 0. The response in both v_xmlcode and v_response_header is null. Its as if it was not executed in the first place (other than the variable v_xmlcode being NULLed). I am obviously doing something wrong but I have no idea what. Any suggestions?   Thanks in advance. Col.


  1. One thing I forgot to mention. This will run in a normal client-server application. It is not web based.   Col.

  2. Colin, I'm pretty sure you can get the WSDL for this SOAP service and import it directly to Uniface. Once you have it in Uniface, you can activate it directly.... No need to use uhttp... idf /sti /mwr=ws {/bare} {/dataonly} {/gen=Options} {/nosig} {/verbose} {/mod=ModelName} WSDL Regards, Knut
