Re: Reg: Web Service in IBMi

Yes. I see that. I did mine before this was available. This is an
interesting thread, and Kevin's link below is very useful.

Just this week I was working with a REST Web Service (as the consumer)...
This particular one DID actually return a JSON payload with HTTP 4xx
errors. I thought that to be odd. Here is an example:
{
"message" : "Incorrect data supplied. The following order lines have not
been decided: R356858528-A-3, R356858528-A-1, R356858528-A-2.The following
order lines are not associated with the current order: R356858528-A.",
"status" : 400
}

In this case, the HTTP ERROR was 400.

Hi Greg,

The Initial request is an RPG Program only.

I am receiving input in JSON string, but while sending it back i will just
populate the data into an Data Structure and Web Service itself will
convert the data into JSON format while sending it to the Client. So i am
using http status code to send the response code to the Client.

But as Kevin replied,

https://developer.ibm.com/tutorials/i-rest-web-services-server1/

400 and 500 range error messages don't send the body it seems. So in my
case i don't have any other option it seems.

Regards,
Surender K

I would like to help... but I don't understand what is processing your
initial request (is it an RPG program, or something else?).

I have several web services running on our machine, but they are
invoking RPGLE pgms.. I can return whatever payload I want.

Hello Everyone,

I started the Web Server in IBMi and configured a Export Procedure
which has 3 Parameters, Parameter 1 as Input (JSON String),
Parameter
2 as Output Response (JSON String) and Parameter 3 as httpStatus code.

Now whenever i am returning httpstatus code as 200 or 201 i can see
the Output response JSON string in my Interface (I am using
POSTMAN), but when i returning httpstatus code as 400 (Error) then
the Output JSON string is completely suppressed. I am not getting
the Output string

in Interface.

Is there is any configuration i need to enable to view the Output
string even when error code is not 200 or 201?

Regards,
Surender K
