解决angularjs service中依赖注入$scope报错的问题

控制台错误提示

ionic.bundle.js:26794 Error: [$injector:unpr] Unknown provider: $scopeProvider <- $scope <- DutylogService

原因：

angular.module('myModule', [])
.service('MyController', ['$scope', function($scope) {
 // This controller throws an unknown provider error because
 // a scope object cannot be injected into a service.
}]);

建议方式：

.service('DutylogService', [function(){
 
}])
