Re: Basic authentication fails probably because of Base64 enconding

[Mirco Andreon <mirco.andreon@xxxxxxxxxxxx>]

   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
   '[1]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 ('[2]bubi@xxxxxxxxxxx'). I tried this:

     if %trim(email) = *blanks;
       email = '[3]bubi@xxxxxxxxxxx';
     endif;

   but doesn't enter if-block.
   Could give me an hint? I'm new to RPGLE. Thanks!

   More info: it seems not to be an encoding problem. If I try with a
   string literal instead of a variable
   http_setAuth( HTTP_AUTH_BASIC : '[[4]1]bubi@xxxxxxxxxxx' : '');
   the encoding is ok (YnViaUBleGFtcGxlLm9yZzo=).
   So this is not the problem. All seems the same now on both Web Services
   Explorer and HTTPAPI, but the latter doesn't work (always Bad Request).

   Hello, I'm trying to invoke this web service:

     WSDL: [2][5]http://www.nexusonline.it:8088/4DWSDL
     endpoint: [3][6]http://www.nexusonline.it:8088/4DSOAP/
     instructions: [4][7]http://www.nexusonline.it:8088/esempio4d
     method: Get_BankFromCAB
         parameters:
             ABI, 5 chars code
             CAB, 5 chars code
     Authentication: basic with an email as username and an empty string
     as password

   This is how Eclipse Web Services Explorer allows me to invoke it
   (following is Wireshark capture of the HTTP request):

     POST /4DSOAP/ HTTP/1.1
     Host: [5]www.nexusonline.it:8088
     Content-Type: text/xml; charset=utf-8
     Content-Length: 590
     Accept: application/soap+xml, application/dime, multipart/related,
     text/*
     User-Agent: IBM Web Services Explorer
     Cache-Control: no-cache
     Pragma: no-cache
     SOAPAction: "Nexus_WebService#Get_BankFromCAB"
     Authorization: Basic YnViaUBleGFtcGxlLm9yZzo=
     Connection: close

   [SOAP envelope omitted, because it's like mine]
   and it works.
   This is how I invoke it by HTTPAPI:

     http_setAuth( HTTP_AUTH_BASIC : %trim(email) : '');
     rc = http_url_post(
                         '[6][8]http://www.nexusonline.it:8088/4DSOAP/'
                       : %addr(SoapReq)+2
                       : %len(SoapReq)
                       : soapfile
                       : HTTP_TIMEOUT
                       : HTTP_USERAGENT
                       : 'text/xml; charset=utf-8'
                       : '"Nexus_WebService#Get_BankFromCAB"' );

   and it doesn't work.
   This is an extract from '/tmp/httpapi_debug.txt':

     POST /4DSOAP/ HTTP/1.1
     Host: [7]www.nexusonline.it:8088
     User-Agent: http-api/1.24
     Content-Type: text/xml; charset=utf-8
     SOAPAction: "Nexus_WebService#Get_BankFromCAB"
     Content-Length: 594
     Authorization: Basic
     YnViaUBleGFtcGxlLm9yZyAgICAgICAgICAgICAgICAgAAAAAAAAAAAAAAAAAAAAAAA6

   [if I read further I can see SOAP response saying
   <SOAP-ENV:Fault><faultcode>SOAP-ENV:Client</faultcode><faultstring>Bad
   Request.</SOAP-ENV:Fault>]
   The only difference I see is Authorization parameter. I always use
   username [8][9]"bubi@xxxxxxxxxxx" and empty password, but seems HTTPAPI is
   encoding in a slightly different way. Also putting double-quotes in
   SOAP action seems strange to me but I don't think it's the problem.
   Any help is appretiated, thanks!
