Re: Return PDF in Rest Service -- WEB400

What Code page is the PDF in your IFS?

What format is the PDF returned to client 2? It looks like a straight PDF
file... so why are there yajl functions in it and building arrays, etc?

Where are you loading the PDF in this code? Is it already in jsonBuf? How
did it get there? From other code not in the sample source?

If you were to use something like eRPG SDK or CGIDEV2 to return the PDF
document it would be a lot easier. Write out headers, load the PDF as the
template, and write it out. eRPG example:

#startup();
#writeTemplate('stdPDFheader.erpg'); <--- this contains
headers like Content-type: application/pdf with 2 new lines
#setCCSIDStdOut(1208);
#writeTemplate(yourPDFFile);
#cleanup();

*INLR = *on;

Hi there,
I'm having great difficulty in returning a PDF Document in a REST Service
request.

Background:

I'm facilitating a Webservice between 2 External parties

I receive a JSON request from Client 1, parse the info, call an API (Via
Scott's HTTPAPI) on Client 2's Systems, receive the response as a PDF
Document which I store on the IFS.

Now I need to pass this PDF Document back to Client 1 as a response to
their API call, and this is where I'm getting Garbage in the PDF Document.

Code Snippet:

yajl_genOpen(*on);
yajl_beginArray();
yajl_beginObj();
yajl_addChar('UploadStatus' : 'A');
yajl_addChar('UploadMessage' : %Trim(RspString));
yajl_addChar('HHSCore' : %Trim(w_HHSCore));
yajl_endObj();
yajl_beginObj();
yajl_addCharStmf('ResponseDocument' : DocPath: ErrMsg);
yajl_endObj();
yajl_endArray();
sts = 200;
// This is the response I log for error\troubleshoot\later investigations
etc.
Response = '[{"UploadStatus":"A",' +
'"UploadMessage:"' +%Trim(RspString) + '",' +
'"HHSCore":"' + %Trim(w_HHSCore) + '"},{'+
'"ResponseDocument":"' + %Trim(Docpath) + '}]';
doLogging();
// the following code acts like yajl_writeStdout. I need
content-type to be different
rc = yajl_getBuf( jsonBuf: jsonSize );
Headers = 'Status: ' + %editc(sts:'X') + CRLF +
'Content-type: application/pdf' + CRLF +
// 'Content-type: application/json charset=utf-8' + CRLF +
// 'Content-type: application/octet-stream' + CRLF +
// 'Transfer-Encoding: identity' + CRLF +
'Content-Encoding : gzip' + CRLF +
'Content-Disposition: attachment; filename=' +
%Trim(w_File) + CRLF + CRLF;
QtmhWrStout ( %addr(Headers) + 2 : %len(Headers) : APIError );
offset = 0;
dow jsonSize > 0;
length = jsonSize;
if length > ChunkSize;
length = ChunkSize;
endif;
QtmhWrStout ( jsonBuf + offset : length : APIError );
jsonSize -= length;
offset += length;
enddo;
//yajl_writeStdout(sts: msg);
yajl_genClose();

This runs fine and returns the Document, but the PDF is all garbage. I'm
not too sure if yajl_addCharStmf() is the correct procedure to use.

I'm using both Postman and SOAPUI for testing.

Kind Regards,

Toni Schaake.
