i2Rest basic implementation

ECHO

ECHO is a service included in i2Rest package for testing purposes. It does nothing more than replies to request with the counter value.

i2Rest Client

The easiest way to test your i2Rest Server is to call service ECHO using i2Rest Client. i2Rest Client supplied in i2Rest package, you don't need any REST testing tool installed.
Make sure i2Rest library is in the library list, and just execute the next command:

I2REST COMMAND(*POST)                                         
       URL('<Main Gate URL>/run_program/echo/echo')                                               
       BODY(*N '{"input":{"echo":"0"},
                 "joblog":true,
                 "tracein":true, 
                 "traceout":true}'
            'application/json')   
       OUTPUT(*JOBLOG)                                        
       AUTHMETHOD(*NONE)                                      

And check the result in joblog:

Server response (status 200, shown 280 bytes of 280):
{
  "output": {                                                    
    "echo": "2"                                                  
  },                                                             
  "joblog": [                                                    
    "Input:",                                                    
    "echo (10):",                                                
    "000000 :0               :F0 00 00 00 00 00 00 00   00 00",  
    "Output:",                                                   
    "echo (10):",                                                
    "000000 :2               :F2 00 00 00 00 00 00 00   00 00"   
  ],                                                             
  "job": "123456/USRX/JOBNAME"                                   
}                                                                 

As you can see i2rest Server responded with "OK" status 200, and the response contains ECHO output object.

SOAP UI

We assume that you already have Soap UI installed. If not, open source installation package could be found on https://www.soapui.org/downloads/soapui/.
Run SOAP UI, then go to File ---> New REST Project. Specify URI to request as follows: <Main Gate URL>/run_program/echo/echo, where Main Gate URL is the value, that was set up during initial server configuration. -

CURL

We assume that you already have CURL installed.
