so i assume, the first_key is passed by request.vars as a binary
but when trying to execute it on terminal (create another file then execute
: *python test0.py* it work e.g. *results = reader.decode(filename.png*)
*objective*
user send data file via curl, and web2py process the file and return it
content text
*question*
any idea how to achieve it using web2py way ?
thanks and best regards,
stifan
