POST
Here is am going to give complete exercise as to how shall
we implement an OSB service which will intern call a REST based service
endpoint making POST request.
To move ahead with this exercise we need to first know the Rest
Service Endpoint, Request message and Response message etc.
We shall first test the service using any (or all) of the
below tools:-
Postman Test Suite
SoapUI
CURL
Let’s start with the implementation. Below are the
pre-requisites to know before you start:-
Endpoint- http://10.11.12.50:1050/resource
Sample Request-
{"AO":"VMAC""BN":"0""AR":"0011223344556677""BO":"6""BP":"20FC79C7"}
Sample Response-
{"COMMAND": "[AOVMAC;AE1009;BBY;]", "AE": "1009", "AO": "VMAC", "BB": "Y"}
Below is
the screenshot from Postman Test Suite
Screenshot of request-response from SoapUI
Screenshot of request-response from CURL
Once you test through SoapUI, after getting successful response,
just click the ‘RAW’ tab. It will provide with all the header information
needed to call the Rest service endpoint. See the screenshots below:-
Implementation
Create business service (Steps):-
- Create a configuration project and then an OSB project in OSB editor (eclipse)
- Right click on the project and then Goto “New->Business Service”
- Give any name to the business service. I have given name as “myRestServiceBS”
Once it opens in editor, select ‘Messaging
Service’ as ‘service type’ in ‘general’ tab and also follow below screenshots:-
No other setting is needed to configure except for those
which you can see in above pictures. Leave rest of the things as it is.
Now, the Business Service (BS) is ready to test. Just deploy
this on sbconsole and click on test button
NOTE:- No URI or relative-URI or parameters are
needed to pass while testing BS through OSB console. Only transport
header/header values are needed to pass which depends on service to service
(REST Service). So, in our case we just need to pass below information along
with Body to BS while testing:-
You will get the response as below:-
