angularjs中factory,service,provider 自定义服务的不同

'use strict';

/* Services */

var phonecatServices = angular.module('phonecatServices', []);

phonecatServices.factory('facetorytest', ['$window', //factory方式
function($window){
var test = {
firstname:"tank",
lastname:function(){
return "zhang";
}
};
$window.alert('aaaa'); //内置服务可以注入
return test;
}
]);

phonecatServices.service('servicetest', ['$window', //service方式
function($window){
$window.alert('bbbb'); //内置服务可以注入
this.firstname = "tank";
this.lastname = function(){
return "zhang";
}
}
]);

phonecatServices.provider('providertest',[ //provider方式，内置服务不可以注入
function(){
this.test = {
"firstname":"tank",
"lastname":"zhang"
}
this.$get = function () {
return this.test;
};
}
]);

'use strict';

/* Controllers */

var phonecatControllers = angular.module('phonecatControllers', []);

//写过js function的对这种调用方式，很熟悉，服务名称不能变
function TestCtrl($scope,facetorytest,servicetest,providertest) {
$scope.facetorytest = facetorytest.firstname+" "+facetorytest.lastname();
$scope.servicetest = servicetest.firstname+" "+servicetest.lastname();
$scope.providertest = providertest.firstname+" "+providertest.lastname;
}

//这种调用方式根jquery非常的像，服务名称也不能变
phonecatControllers.controller('TestCtrl',function($scope,facetorytest,servicetest,providertest) {
$scope.facetorytest = facetorytest.firstname+" "+facetorytest.lastname();
$scope.servicetest = servicetest.firstname+" "+servicetest.lastname();
$scope.providertest = providertest.firstname+" "+providertest.lastname;
});

//以注入的方式来调用，服务名称可以改变
phonecatControllers.controller('TestCtrl',['$scope',"facetorytest","servicetest","providertest",
function($scope,facetory111,service111,provider111) { //自定义,服务名称
$scope.facetorytest = facetory111.firstname+" "+facetory111.lastname();
$scope.servicetest = service111.firstname+" "+service111.lastname();
$scope.providertest = provider111.firstname+" "+provider111.lastname;
}
]);www.111com.net

'use strict';

/* App Module */

var phonecatApp = angular.module('phonecatApp', [
'ngRoute',
'phonecatControllers', //上面定义的controller
'phonecatServices' //上面自定义的服务
]);

显示结果：

tank zhang
tank zhang
tank zhang

phonecatServices.provider('providertest',['$window',
function($window){
$window.alert('cccc'); //报错
this.test = {
"firstname":"tank",
"lastname":"zhang"
}
this.$get = function () {
return this.test;
};
}
]);
