将写好的shell脚本放在/www/cgi-bin/目录下

#!/bin/sh

process_query_string()
{
  local i msg _name _val IFS="&"
  for i in $QUERY_STRING; do
    _name=${i%=*}
    [ "$_name" = "$i" ] && _val= || _val=${i#*=}
    eval $_name=$_val
  done
}

[ "$REQUEST_METHOD" = "POST" ] && read QUERY_STRING

process_query_string

echo "Content-type: text/html;charset=UFT-8"
echo ""
echo "i am $name ,$age years old"
echo "posted data is $QUERY_STRING" >&2
