Using File::Temp module with System command in Perl - perl

Question

following is my Perl code:
use strict;
use File::Find;
use MIME::Base64;
use File::Temp qw(tempfile);
sub loadFiles(); #udf
sub mySub(); #udf
my #files = ();
my $dir = shift || die "Argument missing: directory name\n";
my $finalLoc;
my $filePath;
my $fileContents;
my $base64EncFile;
my $domain = "WTX";
my $devFilePath;
my $deviceDir;
my $position;
my $user = "admin";
my $encPwd = "YzNKcGNtRnRZVEF4";
my $decPwd;
my $response;
my $temp;
my $tempFilename;
loadFiles(); #call
foreach (#files) {
#take the file path into a variable
$filePath = $_;
#replace the '/' with '\' in the file path
$filePath =~ s/\//\\/g;
#take the file path into a variable
$devFilePath = $_;
#replace the '\' with '/' in the file path
$devFilePath =~ s/\\/\//g;
#perform string operation to derive a target file path
$position = index( $devFilePath, "RPDM" );
$deviceDir = "local:///" . substr( $devFilePath, $position );
#open handle on file to read the contents
open( FILE, "< $filePath" );
#read the entire file into a variable, 'fileContents'
$fileContents = do { local $/; <FILE> };
#base64 encode the file contents
$base64EncFile = encode_base64($fileContents);
#replace the <CR><LF> characters in the file and flatten the base64 string
$base64EncFile =~ s/[\x0A\x0D]//g;
#printing file path
print "FilePath=$filePath\n";
#creating a temp file with 9 random characters at the end, example 'tempUKv1vqBTp'
$temp = File::Temp->new(
TEMPLATE => "tempXXXXXXXXX",
UNLINK => 0
) or die "Could not make tempfile: $!";
$tempFilename = $temp->filename;
#Printing temp file name
print "TempFileName=$tempFilename\n";
#open the temp file for writing
open(TEMP, ">$tempFilename");
select(TEMP);
while($base64EncFile){
#??? HOW TO PRINT THE VARIABLE $base64EncFile CONTENTS INTO THE TEMP FILE ???
}
#creating a final request for sending to the web service
my $dpString = "<env:Envelope xmlns:env='http://schemas.xmlsoap.org/soap/envelope/' xmlns:dp='http://www.datapower.com/schemas/management'><env:Body><dp:request domain='$domain'><dp:set-file name='$deviceDir'>". $base64EncFile."</dp:set-file></dp:request></env:Body></env:Envelope>";
#decode the encoded password
$decPwd = decode_base64($encPwd);
system('C:\\apps\\curl-7.15.0\\curl.exe', '-#', '-k', '-u', "admin:$decPwd", '--data-binary', "$dpString", 'https://host/service/fileSet');
print "-----------------------------------------------------------\n";
close(TEMP);
close(FILE);
}
sub loadFiles() {
find( \&mySub, "$dir" ); #custom subroutine find, parse $dir
}
# following gets called recursively for each file in $dir, check $_ to see if you want the file!
sub mySub() {
push #files, $File::Find::name
if (/(\.xml|\.xsl|\.xslt|\.ffd|\.dpa|\.wsdl|\.xsd)$/i)
; # modify the regex as per your needs or pass it as another arg
}
Task I am trying to accomplish is, given a folder argument to the above perl program will make recursive calls to a given web service end point. Problem is - using the System command in Perl is unable to send files over 32 Kb. While trying to use File::Temp module in perl, I am not sure how to set the contents of a variable into a temp file (my first week using Perl).
Any help to achieve this will be helpful. Thanks!

Are you asking how to write a string to an open file?
print $fh $string;
should do the trick.
In your example, that would translate to replacing L62-65 with something like:
print TEMP $base64EncFile;
