You can always delay the injection and do it at runtime:
app.factory('something',['$injector', function($injector){
return {
doSomething: function() {
return $injector.get('injectedServiceName').someFn();
},
getSomeInstance: function () {
var Something = $injector.get('Something');
return new Something();
}
};
});
That is always a workaround for circular dependencies and the only way to
go (I know of), if you really need circular dependencies.
For you this would mean:
app.factory('RequestTransformer', [
'config', '$injector',
function(config, $injector) {
return {
request: function(config) {
var user = $injector.get('UserService').get();
if (user) config.headers['x-user-token'] = user.id;
config.headers['x-api-key'] = config.apikey;
config.headers['x-api-version'] = config.apiversion;
return config;
}
}
}
]);
Cheers!
