Re: Reg: JSON Field Name modification in HTTPD Configuration File

The only way I can think of that would facilitate such easy changes would
be to use a template approach to building the json.

There's an example here for XML but the technique is equally applicable to
json.

Hi Jon,

I’ve created the JSON in the RPG program and uploaded it to the standard
output area using QtmhWrStout. The HTTP Server automatically retrieves

the

JSON data from this area and sends it to the client.

We’ve installed the program into production, but after the installation,

we

received a request to modify a field name in the JSON response. While we
can achieve this by altering the RPG program where the JSON is generated,
this would require a process to promote the object into production, which
will take some time.

I’m wondering if there’s a way to make this modification without changing
the RPG program itself, possibly by adjusting the HTTP server

configuration.

Suren

So how are you generating the json?

There are too many possible options without knowing the current method.

Hi Jon,

No I use the CGI call method only HTTP Server and no application

server.

I will configure the below lines in the HTTPD configuration file

ScriptAlias /CUSTOMER/1.0/details /qsys.lib/TESTLIB.lib/Program01.pgm
ScriptAliasMatch /CUSTOMER/1.0/verify/(.*)
/qsys.lib/TESTLIB.lib/Program02.pgm

HTTP Server will directly call the programs Program01 and Program02

based

on the url

Hi All,

I use an HTTP Server on IBMi with a CGI call method to handle my web
services. Typically, the JSON response data is generated in an RPG

program

and uploaded to the Standard Output location. The CGI method then

retrieves

this JSON data from Standard Output and sends it as a response to the
external client.

Currently, I have a requirement to modify the field names in the JSON
response. For example:
Original data:
{
"firstName": "John",
"lastName": "Doe"
}

Modified Data:
{
"customerFirstName": "John",
"customerCLastName": "Doe"
}

The goal is to change the field name "firstName" to

"customerFirstName"

and

"lastName" to "customerLastName".


Is there a way to achieve this by adding some configuration to the

HTTPD

file, or is modifying the RPG code the only viable solution?

I’d greatly appreciate any advice or suggestions on this.
Regards,
Suren
