Re: [Gumstix-users] writing dynamic webpages with boa

[Justin T. <jus...@ar...>]

GET is pretty simple. The query string will be stored in an environment 
variable $QUERY_STRING

POST is a bit more work however.

When they post data using the POST method, $CONTENT_LENGTH will contain the 
length of the post data. You must read the data from standard in... heres 1 
way to do it:

QUERY_STRING="`/bin/dd count=$CONTENT_LENGTH bs=1`";

Then, if you want to seperate the key/value pairs and store them in 
environment variables, you can use my shell functions below:

url_decode()
{
   ret=`echo $1 | sed -e 's/+/ /g; s/%/\\\x/g'`;
   echo -e "$ret";
}

#
# Parses GET url variables and stores them as WWW_varname
#

function parsevars ()
{
  VAR_PREFIX=WWW_

  for var in `echo $1 | sed -e 's/&/ /g'`
  do
    key=`echo $var | awk -F= '{print $1;}'`;
    val=`echo $var | awk -F= '{print $2;}'`;
    export ${VAR_PREFIX}${key}="`url_decode $val`";
  done
}
