Net::Dopplr - interface with Dopplr.com's web service

    my $dopplr = Net::Dopplr->new($token);

    my $fellows = $dopplr->fellows('muttley');

    print "I share my trips with ".scalar(@{$fellows->{show_trips_to}})." people\n"; 
    print "I can see ".scalar(@{$fellows->{can_see_trips_of}})." people's trips\n"; 

This is a bit involved because Dopplr is still in beta.

First visit this URL

    https://www.dopplr.com/api/AuthSubRequest?next=http%3A%2F%2Fwww.example.com%2Fdopplrapi&scope=http%3A%2F%2Fwww.dopplr.com%2F&session=1

(Or you can replace next with you own web app). That will give you a developer token.

You can then upgrade this to a permanent session token using the dopplr utility shipped with this module or code similar to this

    use strict;
    use Net::Google::AuthSub;

    my $token = shift;
    my $auth = Net::Google::AuthSub->new( url => 'https://www.dopplr.com/api');

    $auth->auth('null', $token);
    my $sess    = $auth->session_token() || die "Couldn't get token: $@";
    print "Session token = $sess\n";

and then later

    my $dopplr = Net::Dopplr->new($sess);

You can then use the session token from that point forward.

Opts is a hash where the keys can be

    public 
    url
    address

Update a traveller's details.

Takes a hash with the new values. Possible keys are

    email
    forename
    surname
    password

This is the future proofing method.

If there's any method I haven't implemented yet then you can simply provide the name of the method, the options as a hash ref and, optionally, whether it should be a POST request or not. So, for a theoretical new method called throw_penguin which throws a penguin at a traveller and is called as a POST

    $dopplr->call('throw_penguin', { traveller_id => $id }, 1);

and for get_penguins which finds how many penguins have been thrown at a traveller and is called as a GET

    use Data::Dumper;
    my $data = $dopplr->call('get_penguins', { traveller_id => $id });
    print Dumper($data);
