In this post we will explore the concept of refresh tokens as defined by OAuth2. We will learn why they came to be and how they compare to other types of tokens. We will also learn how to use them with a simple example. Read on! Update: at the moment…

在前一篇博文中,我们初步地了解了refresh token的用途——它是用于刷新access token的一种token,并且用简单的示例代码体验了一下获取refresh token并且用它刷新access token.在这篇博文中,我们来进一步探索refresh token. 之前只知道refresh token是用于刷新access token的,却不知道refresh token凭什么可以刷新access token?知其然,却不知其所以然. 这是由于之前没有发现refresh token…

在前一篇博文中,我们基于 ASP.NET Web API 与 OWIN OAuth 以 Resource Owner Password Credentials Grant 的授权方式( grant_type=password )获取到了 access token,并以这个 token 成功调用了与当前用户(resource owner)关联的 Web API. 本以为搞定了 access token 就搞定了 Web API 的验证与授权问题,可是发现 OAuth 中还有一种 token,叫 r…

本文转自:http://andrewlock.net/an-introduction-to-oauth-2-using-facebook-in-asp-net-core/ This is the next post in a series on authentication and authorisation in ASP.NET Core. In this post I look in moderate depth at the OAuth 2.0 protocol as it pertain…

Authorization server The following data elements are stored or accessible on the authorization server: usernames and passwords client ids and secrets client-specific refresh tokens client-specific access tokens HTTPS certificate/key per-authorization…

适用范围 前面介绍了Client Credentials Grant ,只适合客户端的模式来使用,不涉及用户相关.而Resource Owner Password Credentials Grant模式中,用户向客户端提供自己的用户名和密码.客户端使用这些信息,向"服务商提供商"索要授权. 在这种模式中,用户必须把自己的密码给客户端,但是客户端不得储存密码.这通常用在用户对客户端高度信任的情况下,比如客户端是操作系统的一部分,或者由一个著名公司出品.而认证服务器只有在其他授权模式无法执…

今天从新过了一边node的基础知识,自己写了一个小例子: foo.js exports.setSome = function (x) {return x }; saveData.js /** * Created with IntelliJ IDEA. * User: Administrator * Date: 15-5-21 * Time: 下午12:17 * To change this template use File | Settings | File Templates. */ var…

Refresh tokens can potentially improve the situation but also increase complexity. A refresh token is a long lived token that allows requesting new access tokens without having to present the user credentials again. This means that the access token i…
