服務(wù)公司對(duì)安古拉工廠我都見(jiàn)過(guò)安古拉爾工廠()和angular.service()用于聲明服務(wù)；但是，i找不到 angular.service官方文件里的任何地方。這兩種方法有什么區(qū)別？哪一個(gè)應(yīng)該用來(lái)做什么(假設(shè)他們做不同的事情)？

angular.service('myService', myServiceFunction);
angular.factory('myFactory', myFactoryFunction);服務(wù)
myInjectedService <---- new myServiceFunction()
工廠
myInjectedFactory <--- myFactoryFunction()
比如寫(xiě)一個(gè) 服務(wù)函數(shù)公開(kāi)公共API：
function myServiceFunction() {
this.awesomeApi = function(optional) {
// calculate some stuff
return awesomeListOfValues;
}}---------------------------------------------------------------------------------
// Injected in your controller$scope.awesome = myInjectedService.awesomeApi();或者使用 工廠函數(shù)公開(kāi)公共API：
function myFactoryFunction() {
var aPrivateVariable = "yay";
function hello() {
return "hello mars " + aPrivateVariable;
}
// expose a public API
return {
hello: hello };}---------------------------------------------------------------------------------
// Injected in your controller$scope.hello = myInjectedFactory.hello();或者使用 工廠函數(shù)返回構(gòu)造函數(shù)：
function myFactoryFunction() {
return function() {
var a = 2;
this.a2 = function() {
return a*2;
};
};}---------------------------------------------------------------------------------
// Injected in your controllervar myShinyNewObject = new myInjectedFactory();$scope.four = myShinyNewObject.a2();用哪一個(gè)？.
var myShinyNewObject = new myInjectedService.myFunction()
var myShinyNewObject = new myInjectedFactory();
new()
還有一件事，他們都是單身.。

// Serviceservice = (a, b) => {
a.lastName = b;
return a;};// Factoryfactory = (a, b) => Object.assign({}, a, { lastName: b });const fullName = { firstName: 'john' };
// Service
const lastNameService = (a, b) => {
a.lastName = b;
return a;
};
console.log(lastNameService(fullName, 'doe'));
// Factory
const lastNameFactory = (a, b) =>
Object.assign({}, a, { lastName: b })
console.log(lastNameFactory(fullName, 'doe'));
