常量

Created: November-22, 2018

Constant 在配置階段和執行階段均可用。

angular.module('app',[])
  .constant('endpoint', 'http://some.rest.endpoint') // define
  .config(function(endpoint) {
    // do something with endpoint
    // available in both config- and run phases
  }) 
  .controller('MainCtrl', function(endpoint) {       // inject
    var vm = this;
    vm.endpoint = endpoint;                          // usage
  });

<body ng-controller="MainCtrl as vm">
  <div>endpoint = {{ ::vm.endpoint }}</div>
</body>

endpoint = http：//some.rest.endpoint
