自定义服务与调用--------factory

自定义服务：

angular.module('myApp').factory('UserService',['$http','$q',function ($http,$q) {
    // 定义一个方法工厂
    var  factory = {
            httpGet : httpGet,
            login:login
    };
    return factory;
    
    function httpGet(no,size) {
        var deferred = $q.defer();
        $http.get("/user/list.action?pageSize="+size+"&pageNo="+no)
        .then(function (response) {
            deferred.resolve(response.data);
        },
            function (errResponse) {
                console.error("Error ！！")
                deferred.reject(errResponse);
            }
        );
        return deferred.promise;
    }
    
    function login(params) {
        var deferred = $q.defer();
        $http({
            method  : 'POST',
            url     : '/user/login.action',
            data    : $.param(params),  // pass in data as strings
            headers : { 'Content-Type': 'application/x-www-form-urlencoded' } , // set the headers so angular passing info as form data (not request payload)
               dataType:'json'
      })
        .then(function (response) {
            deferred.resolve(response.data);
        },
            function (errResponse) {
                console.error("Error ！！")
                deferred.reject(errResponse);
            }
        );
        return deferred.promise;
    }
    
}]);

服务调用：  引入js

var app = angular.module('myApp', []);
app.controller('userCtrl', function ($scope, $http,UserService) {
/******************paging************pageSize******/
         $scope.pageSize=6;
        $scope.pagesize = {
                 5 : 5,
                15 : 15,
                 30 : 30
            }
        //httpGet(2,8);
        $scope.selectchange=function(){
            //debugger
            UserService.httpGet($scope.page.number,$scope.pageSize).then(function (d) {
