This tutorial introduces RMNet, an HTTP web client callable from ACUCOBOL-GT extend. The tutorial shows you how to use the RMNet Application Programming Interface (API) to emulate a browser that extracts information from a web site or interacts with a web service using SOAP.
RMNet moves data between the a web client, which is typically an ACUCOBOL-GT extend program, and a web server. A Universal Resource Locator (URL) describes the resource. The resource dictates the data format. For example, if submitting data to a web form used by a browser, the data must be formatted to comply with the W3C specification for application/x-www-form-urlencoded. When interacting with a SOAP web service, XML documents are exchanged.
This tutorial also describes how the temperature conversion sample program was created. This program is in the %PUBLIC%\Documents\Micro Focus\extend x.x.x\sample\rmnet folder. Additional information is also provided that may be used when scripting an HTTP interaction with a web server.
