HTTP Data Being Changed

dlwester has asked for the wisdom of the Perl Monks concerning the following question:

I am calling a remote Perl service from a Perl script with the following code:
my $userAgent = LWP::UserAgent->new; my $request = HTTP::Request->new(); $request->uri($buildManagerUrl); $request->method("POST"); my $postData = "action=$action\&params=$callParamsJson"; my $content = encode("iso-8859-1", $postData); $request->content($content); $request->content_type("application/x-www-form-urlencoded"); my $response = $userAgent->request($request);
When I print out the request data, one of the fields in the embedded XML in the content is:
Here's the code that retrieves the data sent above:
my $q = new CGI(); my %params = $q->Vars(); print Dumper($q);
However, when I look at the request in the Dumper output, the '+' in the data is being replaced by a space:
<password>XUvN 5R3</password>
I'm guessing I'm probably just using the wrong encoding, but I have no idea how to resolve this. Any ideas?

    You're doing weird things with the low-level parts of the LWP API. This is much shorter and actually working as intended (takes care of assembling and encoding the request the correct way):
    use LWP::UserAgent qw(); my $response = LWP::UserAgent ->new ->post( $buildManagerUrl, { action => $action, params => $callParamsJson, } );
      Thanks, that simplified my code a lot. But my problem remains - the '+' is still a ' ' on the other side of the wire.
