I'm creating a webservice and using IWS. I'm then using Postman to test
the webservice. All the endpoints call procedures in a service program..
So 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.
I'm trying to understand how to extract the parameter whid=93 from the
QUERY_STRING. I thought the article I posted gave an example of this.
Thanks,
Rob

That's unlikely to provide your answer...
First off, you need to clarify what you are doing?
Calling web service?
Create a web service (with or with IWS?)

Charles, if I add *fixed then does this stop the need to append x'00'
https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_73/rzaie/rzaiepdf.pdfthe end of cmdstr when calling the api?
I checked in the config file for my HTTP server instance and could not
find %%MIXED%%. So I did a Google search and did find . Electronic
business and Web serving IBM HTTP Server for i (
).you
It mentions
CGIConvMode:
Module: mod_cgi
Syntax: CGIConvMode mode
One of the modes listed is %%MIXED so I'm thinking this may be what
understandwere referring to. But this also got me thinking, from how I
doingthis, CGIConvMode is in module the module mod_cgi which is not loaded
(LoadModule cgi_mod?).
Should I be loading cgi_mod?
OK, while writing this I just saw another post from you that I was
usingit wrong. Thanks
In the past I did try to find how to access the environment variable
QUERY_STRING but the only reference I could find to access it was
rogersonra@xxxxxxxxx>the QzhbCgiParse api which you pointed out is wrong.
So how should I be accessing QUERY_STRING? (I don't mind if you just
point me to a document but I couldn't find one.
Thanks,

Looks ok, though you should be using option(*trim:*string) to
automatically
trim and null terminate the cmdStr parm.
Did you see the note in the docs?
This API does not work with the %%MIXED%% CGI input mode.
Are you by chance using mixed? (would be in your Apache config)

I'm using IWS to call a REST API. I'm using QzhbCgiParse to

I've used Google and the IBM API docs to research but I can't see

If responseLen > 0;
pos = %SCAN(X'25':targetBuf);
Return %Trim(%Subst(targetBuf:1:pos-1));
Else;
Return ' ';
Endif;
end-proc;
I've commented out the call to QzhbCgiParse and the program
Itcallwithout error and produces a dump (dump(a)). When I uncomment the
to
QzhbCgiParse the program fails but produces no dump for dump(a).
mailingdoes
however create the QPSRVDMP dump I mentioned earlier.
Any help would be greatly appreciated as I've come to a brick wall.
Thanks,
