Re: Base64 Encoding

Couple of things wrong that jump out.

But in both your calls not just the Base64.

Normally you should not need to %Trim a varchar - the content should have been trimmed when the field was loaded. so %Len(XMLData) should be fine. But it won't cause a problem. But %Addr(XMLData) it should be %Addr(XMLData : *Data ) to get the address of the data portion.

Similarly you should be using the *Data option for the %Addr( xmlData64 ) as well.

The %Size may or may not be right - I don't have the prototype for base64_encode handy. But %Size of a varchar will include the two byte length for the count (i.e. %Size for a 2,048 Varchar would be 2,050) and that is unlikely to be what you want.

Is this the easiest way to Base64 encode and XML document (either in an RPG variable or on the IFS) for use in a SOAP web service?

I've used Scott's BASE64R4 service program for smaller things like API keys, etc.

I've been trying to mock-up a test scenario, and I'm not getting the results I expected - pretty sure I'm doing something wrong with the varchar fields. The code I'm copying was using much smaller fixed length fields.

xmlData and xmlData64 are both varchar(2048)... however the data is nowhere near that large (utflen=710).

http_setCCSIDs( 1208: 0 );
utflen = HTTP_xlatedyn( %len(%trim(xmlData))
: %addr(xmlData)
: TO_ASCII
: p_xmlDataUTF );

b64len = base64_encode( p_xmlDataUTF
: utflen
: %addr(xmlData64)
: %size(xmlData64) );

dealloc p_xmlDataUTF;


My resulting data in xmlData64 does not match the online encoders.

Thanks,
Greg
