Hi Etienne,
I've actually wrapped the *SOAP::WSDL::Client::call call in my Moose
classes to trap various errors with Try::Tiny. I've had to set
die_on_faults to true because I don't want to accidentally forget to trap
an error. I fall back to regex tests. My actual code winds up looking like
this:
sub _override_soap_wsdl_client_call {
my $self = shift;
no warnings 'redefine';
*SOAP::WSDL::Client::call = sub {
my ( $soap_object, $method, @data_from ) = @_;
# throttling to avoid the RateExceededError
# it doesn't allow requests more often than .6 seconds
$self->_throttle_request;
$self->_try_soap_call( $soap_object, $method, \@data_from );
};
}
sub _try_soap_call {
my ( $self, $soap, $method, $data_from ) = @_;
my $client = $self->third_party; # Google::Ads::AdWords::Client
my $call = $self->_original_soap_wsdl_client_call;
try {
$soap->$call( $method, @$data_from );
}
catch {
# For each of these error conditions, we take some action and try
the
# call again. If it fails at that point, we don't trap the error.
if (/AuthenticationError.GOOGLE_ACCOUNT_COOKIE_INVALID/) {
log("AuthenticationError: refreshing authentication token");
$self->_refresh_auth_token($client);
}
elsif (/RateExceededError/) {
log("Sleeping for 30 seconds due to RateExceededError");
sleep 30;
}
elsif (/InternalApiError.UNEXPECTED_INTERNAL_API_ERROR/) {
log("Unexpected internal API error on Google's side");
sleep 10;
}
else {
croak $_;
}
$soap->$call( $method, @$data_from );
};
}
(Note that I'm skipping a lot of code here. I'm just showing the structure
of my approach)
Feedback welcome.
Cheers,
Ovid
