$stateParmas作为参数传入时失败,下载了老师的代码之后想要把请求数据的操作放到service中，却遇到了这样的问题
var myServiceApp = angular.module('myServiceApp',[]);
myServiceApp.factory('bookservice', ['$http', '$stateParams', function($http, $scope, $state, $stateParams){
var service = {
test: function(){
console.log($stateParams);
console.log("service success!");
},
getdata: function(){
//console.log($stateParams.booktype);
//return $http.get("./data/book4.json");
//.success(function(){console.log("getdata success!");});
return $http({
method: "GET",
url: "./data/" + $stateParams.booktype + ".json"
});
}
};
return service;
}
]);会报错
TypeError: Cannot read property 'booktype' of undefined
这是怎么一回事，谢谢^_^
