All,
Thanks for all your help. We appear to have overcome the CORS hurdle and
have something that at least is not giving a CORS error in Firefox which is
more than we have had in the last 48 hours.
It turns out that you do need to send 'Access-Control-Allow-Origin' => '*'
with the POST reply. It also turns out that a lot of the headers I was
sending were not needed.
For posterity and because somebody else might find it useful, here is the
full source code (that sounds rather grand for a hack), that works for us.
It does nothing useful expect not throw an error.
#!/usr/bin/perl -w
use Mojolicious::Lite;
options '*' => sub {
my $self = shift;
$self->res->headers->header('Access-Control-Allow-Origin' => '*');
#$self->res->headers->header('Access-Control-Allow-Credentials' =>
'true');
#$self->res->headers->header('Access-Control-Allow-Methods' => 'GET,
OPTIONS, POST, DELETE, PUT');
#$self->res->headers->header('Access-Control-Allow-Headers' =>
'Content-Type');
#$self->res->headers->header('Access-Control-Max-Age' => '1728000');
$self->respond_to(any => { data => '', status => 200 });
};
get '/data' => sub {
my $self = shift;
print "GET found\n";
$self->render(text => 'ok');
};
post '/data' => sub {
my $self = shift;
print "\nPOST 3 found\n";
$self->render(text => 'POST ok' );
};
app->hook(after_dispatch => sub {
my $c = shift;
$c->res->headers->header('Access-Control-Allow-Origin' => '*');
});
app->secrets(['My very secret passphrase.']);
app->start;
Note the commented lines in the options section. We've left them in as they
may become useful. This is something we can build on, we wrote an awful lot
of JavaScript which now needs converting to Perl.
Thanks again for all the help, hopefully I can do the same back some day.
Best wishes,
Rob.
