3 ways to create custom services.
Factory
Service
Provider
As you should know, Angularjs is the backstage staff in the work outside the invention, he mainly applied the background of long-existing layered thinking. So we have to understand the role of the next layer, if you are the front-end people do not understand what is layered, then you'd better ask
First, service guidance when I first started learning angular, the components that were often misunderstood and asked by beginners were the differences between service (), factory (), and provide (). This is where we'll start the twenty-five days of Angular calendar. Second, service In angular, services is created as a singleton object when needed, and is cleared only at the end of the application lifecycle (close the browser) . and controllers will b

convenient methods, such as the factory and service methods in $provide. Factory and service methods in the $providefactory methods and service methods can be seen as shorthand for provider methods, which omit the write $get method, as follows:Factory methodFor The factory method, the return can be any type, so it is no problem to return the string here. 650) th
= s;} function Greeter (a) {This.greet = function () {return salutation + ' + A;}} this. $get = function (a) {return new Greeter (a); };}); We can then does this: Angular.module (' abc ', []). config (function (greeter2provider) {greeter2provider.setsalutation (' Halo ');}); function Controller (greeter2) {expect (Greeter2.greet ()). Toequal (' Halo 123 ');} As a side note, service , factory , and is all value derived from provider. Provider.service
Angularjs encapsulates $ http as the factory method, angularjsfactory
Angularjs has its own encapsulated ajax service $ http. Because it is used to jQuery's ajax, it encapsulates angularjs's $ http by itself. The Code is as follows:
app.factory('dataFactory', function ($http, $q){ var factory = {}; factory.getlist
At first Angularjs often write some code that is not elegant enough! I summed up a bit to see if you guys were shot!-----(this is only for service services and their related!)The following practices are not very elegant

In the service, factory () is a great choice when we only need a collection of methods and data and do not need to deal with complex logic.Note: You cannot use the factory () method when configuring the service with. config ()The service () method is well-suited for use in more functional control serviceNote: You cannot use the service () method when you need to configure the service using. config ()Provide
1. The service created by the factory method is the function of returning an object with a property that has a method.

Factory methods and abstract factories are all part of the factory model, so what is the difference between them? Let's compare them.
First we analyze from the point of view of the factory interface.
