RE: Basic authentication fails probably because of Base64 enconding
Depending on how you are passing email, it would appear you are getting some blanks and then x'00'. Possibly passing from CL and only getting 32 characters "correctly"?
When I pass long strings in CL, I sometimes resort to this.
Dcl &email *char 51
(get &scrnEMail (50 long) from screen)
Chgvar &email (&scrnEMail *cat 'x')
Call rpgPgm &email
In the rpgPgm, the parm is only 50 long and comes in with all the "real" data. I don't remember exactly why I do this but there is some issue with CL passing strings as only xx characters long.
If you are not getting *all blanks in your email parm (and it appears you aren't), that would account for why the if fails.

Subject: Re: Basic authentication fails probably because of Base64 enconding
*I found the real problem*: I was treating SOAP request and response as
if they wrapped XML as a string (with < and > encoding) and not as
real XML. So it is even simpler than I thought.
I'm sorry if I made loose your time reading about my issue...
Anyway this is the *last question*:
I have an input param for my program:
C parm email 50
I use it in HTTP authentication:
http_setAuth( HTTP_AUTH_BASIC : %trim(email) : '');
but seems like %trim doesn't work... it passes a string like
'aaa@xxxxxxx ' followed by invalid chars...
Moreover, if they pass an empty string for email param, I would like to
*set a default value *for it ('bubi@xxxxxxxxxxx'). I tried this:
if %trim(email) = *blanks;
email = 'bubi@xxxxxxxxxxx';
endif;
but doesn't enter if-block.
Could give me an hint? I'm new to RPGLE. Thanks!
