Basics: Connect

  • Uses CFINVOKE, CFOBJECT or CreateObject() to connect


Cfinvoke
CFINVOKE

Cfinvoke example
CFINVOKE Example

    • webservice="http://www.xmethods.net/sd/2001/TemperatureService.wsdl"   

    • method="getTemp"   

    • returnvariable="aTemp">     

  • <cfinvokeargument name="zipcode" value="55987">

  • </cfinvoke>

  • <cfoutput>The temperature is #aTemp#</cfoutput>


Createobject example
CreateObject() Example

  • Connects to service

  • Calls methods separately

  • Can invoke multiple methods per connection

  • <cfscript>

    • ws = CreateObject("webservice", "http://www.xmethods.net/sd/2001/TemperatureService.wsdl"); xlatstring = ws.getTemp(zipcode = "55987");

    • writeoutput("The temperature is " & xlatstring);

      </cfscript>
