Re: DATA-INTO error using YAJLINTO

Your json string is not valid.

Find a json validator and check your string. (Notepad++ has a plugin,
SoapUI or try this link https://jsonlint.com/

I changed you json to the following and then it validated but I am not
sure if you wanted an array for data ?

{
"Code": 400,
"Message": "Error",
"Data": "ConsigneeAddress.Zip Validation failed for property. "
}

Subject: DATA-INTO error using YAJLINTO
Sent by: "RPG400-L"<rpg400-l-bounces@xxxxxxxxxxxxxxxxxx>

I'm trying to use DATA-INTO using YAJLINTO. It's based on one of
Scott's examples.
(https://www.common.org/scotts-iland-blog/parsing-json-data-into/).

This is the test code:

dcl-s json varchar(5000) Inz(
'{"Code":400,"Message":"Error","Data":["ConsigneeAddress.Zip -+
Validation failed for property."]' ) ;

dcl-s Msg varchar( 47 ) ;
dcl-s x int( 10 );

dcl-ds MyData qualified;
Code varchar( 5 ) ;
Message varchar( 50 ) ;
num_Data int( 10 ) ;

dcl-ds Data dim( 50 ) ;
*N char( 50 ) ;
end-ds;
end-ds;

data-into MyData %DATA( json: 'case=any countprefix=num_ +
allowextra=yes' )
%PARSER( 'YAJLINTO' );

Msg = MyData.Message ;
dsply ( 'Code: ' + MyData.Code ) ;
dsply ( 'Msg: ' + Msg ) ;
dsply ( 'Num: ' + %EditC( MyData.num_Data:'1' ) ) ;
for x = 1 to MyData.num_Data ;
dsply MyData.Data( x ) ;
endfor;

*INLR = *On ;
___________

If I have allowextra=yes I receive RNX0356 The document for the
DATA-INTO operation does not match the RPG variable; reason code 15.

Cause . . . . . : While parsing a document for the DATA-INTO
operation, the
parser found that the document does not correspond to RPG variable
"mydata"
and the options do not allow for this. The reason code is 15. The

exact

subfield for which the error was detected is "mydata". The options

are

"case=any countprefix=num_ allowextra=yes". The document name is *N;

*N

indicates that the document is not an external file. The parser is
'YAJLINTO'. *N indicates that the parser is a procedure pointer.

Reason code 15: A call to QrnDiStartArray was made, but the matching RPG

variable or
subfield is not an array.

___________

Without allowextra=yes it points to reason code 5, which is:
The document contains extra names that do not match subfields.
___________

Is this because the Data array is not named? If yes, is there a way
around this?
