问题 Supposed I have a single page application that uses JWT tokens to authenticate against a backend REST api. I transfer the JWT token inside the http header when doing a REST request. So far, so good. Now, supposed I want to download an image from the server, and I want the image only to be accessible for authenticated users.

restapi（0）- 平台数据维护，写在前面

阅读更多关于 restapi（0）- 平台数据维护，写在前面

在云计算的推动下，软件系统发展趋于平台化。云平台系统一般都是分布式的集群系统，采用大数据技术。在这方面akka提供了比较完整的开发技术支持。我在上一个系列有关CQRS的博客中按照实际应用的要求对akka的一些开发技术进行了介绍。CQRS模式着重操作流程控制，主要涉及交易数据的管理。那么，作为交易数据产生过程中发挥验证作用的一系列基础数据如用户信息、商品信息、支付类型信息等又应该怎样维护呢？首先基础数据也应该是在平台水平上的，但数据的采集、维护是在系统前端的，比如一些web界面。所以平台基础数据维护系统是一套前后台结合的系统。对于一个开放的平台系统来说，应该能够适应各式各样的前端系统。一般来讲，平台通过定义一套api与前端系统集成是通用的方法。这套api必须遵循行业标准，技术要普及通用，这样才能支持各种异类前端系统功能开发。在这些要求背景下，相对gRPC, GraphQL来说，REST风格的http集成模式能得到更多开发人员的接受。在有关CQRS系列博客里，我以akka-http作为系统集成工具的一种，零星地针对实际需要对http通信进行了介绍。在restapi这个系列里我想系统化的用akka-http构建一套完整的，REST风格数据维护和数据交换api，除CRUD之外还包括网络安全，文件交换等功能。我的计划是用akka-http搭建一个平台数据维护api的REST-CRUD框架

To test this, I first enabled Windows Authentication in IIS express, by right clicking on my project and going to Properties. Then, I made a simple test controller to see

AzureAD JWT Token Audience claim prefix makes JWT Token invalid

阅读更多关于 AzureAD JWT Token Audience claim prefix makes JWT Token invalid

问题 I'm using the 'adal-node' npm package to authenticate with an AzureAD. This is all working fine and I get a token back. However, the when examining the 'aud' claim in the JWT token I see the audience GUID is prefixed with 'spn:'. I think this is causing me problems when I try to use the JWT token on an already existing Web API. When I authenticate via a WebApp using the same AzureAD the 'aud' claim is NOT prefixed with 'spn:' and I am able to called endpoints on the WebAPI. Can anyone shed

问题 Note: I have seperated my client(Vue.js) and server(DjangoRest). I'm using JWT to validate every request made from the client to the server. Flow- Client sends user credentials to server.

Next, I want to make sure that the access token is auto refreshed 15 mins prior to its expiry. To do this, the stored refresh
