Re: IWS and input parameters... -- WEB400

@Jon, so you are suggesting the pFilterDs input parm(s) be passed as a
character string and then parse them in the RPG. That way I could still
use a GET.
That may work...

@Nadir, thanks for the links. I reread them and I think I have a better
understanding. One question, which I know I'm going to be asked is, why
are you using a POST to retrieve data? I now understand I can do this.
But is the reason that there is a restriction in IWS (as there is more than
one parameter that is a structure) or is this a restriction of all web
service servers?

Thanks,

Rob

I don't have time to play but, if you want to stick with GET, can you not
add an extra simple input parm to deal with this?

I'm new to this so I'm trying to understand.
If I want to return rows, normally I would use a GET. But since one of

my

input parameters is a structure I'm forced to either use a POST or a PUT.
So I'm sort of forced out of the convention that GET is to read records,
POST is to create records and PUT is to update records.
So it's ok to do a POST only to read records?

Is there anyone else using IWS from an RPG perspective that has found or
could share some useful information?

Thanks,

Rob

the suffix _LENGTH must be capital because that is what IWS

currently

looks for. It should not matter because it is not part of payload.

If you have a structure that is an input parameters, then the HTTP

method

is POST or PUT.

Other than what we have for doc on web site, and articles, that

is

all the doc there is. We are in process of updating the doc.

@Nadir, your assumption is correct, pFilterDs is indeed input. So you

are

saying that I can have a data structure as input?

Why must the "_lenght" be in upper case. I've never seen nor

understand

this requirement.

Thanks,

Rob

Which parameters are input and which output?

And "_length" suffix should be "_LENGTH"

Assuming pFilterDs is input, you may want to define a length

field

for it as well so that you know how many entries are being passed

in.

I want to have a filter(s) for my api.
An individual filter is defined as

dcl-ds filterTmp template qualified;
type char(20);
value char(20);
end-ds;

But there may be multiple occurrences of filter. For example,

'Warehouse': '95,96,97'
'Type':'Shipments'
'DateRange': 'LastWeek'

I was hoping to do something like
dcl-pi *n;
pFilterDs likeds(filterTmp) dim(10) const;
transactionDs_length int(10);
transactionsDs likeds(transactionsTmp) dim(1000);
httpStatus like(httpStatusTmp);
httpHeaders like(httpHeadersTmp) dim(10);
end-pi;

But when I try this on Step 5 of 9 on the Deploy New Service Wizard

I

get

error
*Error:* ZUI_54411: The HTTP method must be PUT or POST when there

is an

input parameter that is not being injected with a value.

How should I be doing this?
