Interceptor to change the URL
Hey :)
Just trying to do the following:
class HostInterceptor extends Interceptor {
final Connectivity _connectivity;
final PreferencesProvider _preferencesProvider;
final LocalServerProvider _serverProvider;
String _host;
ConnectivityResult _previousConnectivity;
String _previousWifiIp;
HostInterceptor({
Connectivity connectivity,
LocalServerProvider serverProvider,
PreferencesProvider preferencesProvider,
}) : _connectivity = connectivity ?? Connectivity(),
_serverProvider = serverProvider ?? LocalServerProvider(),
_preferencesProvider = preferencesProvider ?? PreferencesProvider() {
if(Platform.isAndroid || Platform.isIOS) {
_connectivity.onConnectivityChanged.listen((connectivityResult) async {
if (_previousConnectivity != connectivityResult) {
_host = null; //reset host to trigger another search on next request
} else if (connectivityResult == ConnectivityResult.wifi) {
final ip = await connectivity.getWifiIP();
if (_previousWifiIp != ip) {
_host = null; //reset host to trigger another search on next request because we change wifi network
}
}
_previousConnectivity = connectivityResult;
});
}
}
@override
FutureOr<void> before(RouteBase route) async {
final url = route.getUrl;
final prefExternalUrl = _preferencesProvider.prefs.getString(PreferencesProvider.keyExternalUrl);
_setExternalUrl(route, url, prefExternalUrl);
return null;
}
_setExternalUrl(RouteBase route, String url, String externalUrl) {
final urlParts = Uri.parse(url);
final externalUrlParts = Uri.parse(externalUrl);
final finalUrl = urlParts.replace(host: externalUrlParts.host, scheme: externalUrlParts.scheme, port: externalUrlParts.port);
route.url(finalUrl.toString());
}
@override
FutureOr after(StringResponse response) {
return response;
}
}
Problem is that it duplicate the path where it shouldn't.
Example:
url on the route is: http://localhost/api/v1/test
external url on pref is: http://myDomain.com
so finalUrl become: http://myDomain.com/api/v1/test
But the url fails because jaguar actually does the request to: http://myDomain.com/api/v1/test/api/v1/test
Didn't find out why :/
