Hi,

You have two options to getting access to query string variable. The
recommended way is to inject the query string parameter into a parameter
automatically.

The alternative way is to pass the entire query string as an environment
variable and within your code you would need to issue a getenv() call and
then parse the query string variable.

Obviously, injecting an input parameter with value of query string
variable is easiest. And this method allows you to specify a default
value as well if not specified.

Subject: [EXTERNAL] [WEB400] IWS, REST and retrieving variables from
QUERY_STRING
Sent by: "WEB400" <web400-bounces@xxxxxxxxxxxxxxxxxx>

Hi All,

I'm creating a REST webservice/api and using IWS. I'm then using
Postman
to test the webservice. All the endpoints call procedures in a service
program..

I have an endpoint /web/server/claims which will call the RPG procedure
GetAllClaims which returns all claims. I have tested this with Postman
and it works correctly.

My next step is to add a filter. So I call the same endpoint but this
time
I pass a parameter of whid. So the endpoint now becomes
/web/server/claims/?whid=93 which will call the RPG procedure
GetAllClaims
but this time I need to extract the parameter passed in the QUERY_STRING
to
return only claims for warehouse 93.

Can someone point me to either documentation or an example of how to
specify and extract from the QUERY_STRING. I've done a lot of searching
on
Google but I must not be searching on the correct terms because I can't
find anything on QUERY_STRING other than that you may specify it..
