Ember-http-hmac

This addon provides an Ember integration for working with version 2.0 of the HTTP HMAC Specification. It wraps the http-hmac-javascript library and exposes signing capabilites both as a mixin for ember-data adapters and for signing individual ember-ajax requests.

Configuration

In order to generate the authorization headers the http-hmac-javascript library needs to know the realm, public key, and secret key to use. These values can be set either in the config/environment.js file or directly on the request-signer service. Optionally, you can configure a list of headers that need to be included in the signature. This is an array of header names that will be included if present in the request.

Setting configuration in the environment

The values can be set in the environment configuration by adding a section to your variables:

module.exports = function(environment) {
  'ember-http-hmac': {
    realm: 'your-realm',
    publicKey: 'enter-your-public-key-here',
    secretKey: 'enter-your-secret-key-here',
    signedHeaders: ['header-name-1', 'header-name-2']
  }
};

Setting configuration directly on the service

The same variables exist on the request-signer servive provided by ember-http-hmac. Here is an example of setting the values within a component:

export default Ember.Component.extend({
  requestSigner: Ember.inject.service();

  init() {
    this._super(...arguments);
    let signer = this.get('requestSigner');
    signer.set('realm', 'your-realm');
    signer.set('publicKey', 'enter-your-public-key-here');
    signer.set('secretKey', 'enter-your-secret-key-here');
    signer.set('signedHeader', ['header-name-1', 'header-name-2']);
  }
});

Using the ember-data adapter mixin

This addon provides a mixin that can be used on any ember-data adapter. Adding this mixin will automatically sign all requests made through the adapter using the configured realm and keys. Using this mixin in your application adapter will add authentication to all ember-data requests by default.

import DS from 'ember-data';
import HmacAdapterMixin from 'ember-http-hmac/mixins/hmac-adapter-mixin';

export default DS.RESTAdapter.extend(HmacAdapterMixin);

Using the ember-ajax service

This addon also provides a service that provides automatic signing to individual AJAX requests. The service extends the ember-ajax Ajax service. To use, include the signed-ajax service and then use as you would the standard ajax service. For example:

import Ember from 'ember';

export default Ember.Route.extend({
  signedAjax: Ember.inject.service(),

  model: {
    return this.get('signedAjax').request('/myendpoint');
  }
});

Using the request-signer service directly

The basic signing functionality used by both the signed-ajax service and the hmac-adapter-mixin is available directly as the request-signer service to use as needed.
