Global ngResource base - angularjs

Question

I have multiple factories in my angular service located in different js file. And there is common base of all the queries:
1) Authorization: Bearer token (header) (required after login)
2) AccessDateTime, UserIPAddress (required before login)
3) AccessDateTime, UserIPAddress, UserID (required after login)
Now, I find that it is very tedious to repeat this on each of the resource. How could i make a base for this? I thought that this is something very common but i could not found any documentation on this. Something like jquery.AjaxSetup().
Default Code
angular.module('app.test').factory('Test', ['$resource',
function($resource) {
return {
resource1: $resource(
url: 'test1/:testId/:AccessDateTime/:UserIPAddress',
headers: { Authorization: Bearer token},
params: { testId: '#_id', AccessDateTime:'#AccessDateTime', UserIPAddress: '#UserIPAddress' }
}),
resource2: return $resource(
url: 'test2/:testId/:AccessDateTime',
params: { testId: '#_id', AccessDateTime:'#AccessDateTime' }
});
}
}
]);
Code after base resource implemented(Illustration only)
angular.module('app.base').factory('FactoryBase'), ['resource',
function($resource) {}
if (resource need authorization) {
auto append header, AccessDateTime, UserIPAddress
} else if (resource do not need authorization) {
auto append AccessDateTime
}
// depending on attribute set with authorize: true/false
}
]);
angular.module('app.test').factory('Test', ['$resource',
function($resource) {
require('FactoryBase'),
return {
resource1: $resource(
url: 'test1/:testId',
authorize: true
}),
resource2: $resource(
url: 'test2/:testId',
authorize: false
}),
}
]);

Put modifier functions in your factory:
angular.module('app.test').factory('Test', ['$resource',
function($resource) {
var defaultConfig1 = {
url: 'test1/:testId/:AccessDateTime/:UserIPAddress',
headers: { Authorization: Bearer token},
params: { testId: '#_id',
AccessDateTime:'#AccessDateTime',
UserIPAddress: '#UserIPAddress'
}
};
var defaultConfig2 = {
url: 'test2/:testId/:AccessDateTime',
params: { testId: '#_id',
AccessDateTime:'#AccessDateTime'
}
};
function mod1(arg) {
var obj = defaultConfig1;
//modify config
return obj;
};
function mod2(arg) {
//modify and return defaultConfig
};
return {
resource1: $resource(defaultConfig1),
resource2: $resource(defaultConfig2).
modified1: function (arg) {
return $resource(mod1(arg));
},
modified2: function (arg) {
return $resource(mod2(arg));
}
}
}
]);
You have the full power of JavaScript to modify the configuration objects as you please before returning them.
