Microsoft Identity is redirecting WebAPI calls to microsoftonline.com

By Builder.services. AddRazor Pages, Using Microsoft. AspNetCore.Authentication.OpenIdConnect, Using Microsoft. AspNetCore.Authorization, Namespace WebAppRazor Aad.Controllers
| microsoft.com
We are trying to build an application with both razor pages and API endpoints and an Angular app to access the API endpoints. Web Application #1 I've been able to connect to Entra ID from the razor page side of the primary AspNet Core web project, and it redirects to Microsoft to login, then redirects back to the site and works fine. Web Application #2 I've also got an Angular site built from the Asp.Net Core SPA template using azure/msal-* npm packages to login to Entra ID.

造轮子之自定义授权策略 - 饭勺oO - 博客园

By Using Microsoft. AspNetCore.Authorization, ITransient Dependency, namespace Wheel.Authorization, Using Microsoft. AspNetCore.Mvc.Controllers
| cnblogs.com
前面我们已经弄好了用户角色这块内容，接下来就是我们的授权策略。在asp.net core中提供了自定义的授权策略方案，我们可以按照需求自定义我们的权限过滤。 这里我的想法是，不需要在每个Controller或者Action打上AuthorizeAttribute，自动根据ControllerName和ActionName匹配授权。只需要在Controller基类打上一个AuthorizeAttribute，其他Controller除了需要匿名访问的，使用统一的ControllerName和ActionName匹配授权方案。 话不多说，开整。 IPermissionChecker 首先我们需要一个PermissionChecker来作为检查当前操作是否有权限。很简单，只需要传入ControllerName和ActionName。至于实现，后续再写。 namespace Wheel.Authorization { public interface IPermissionChecker { Task<bool> Check(string controller, string...

ASP.NET Core 6框架揭秘实例演示[40]：基于角色的授权

| cnblogs.com
ASP.NET应用并没有对如何定义授权策略做硬性规定，但是针对角色的授权策略依然是最常用的。角色（或者用户组）实际上就是对一组权限集的描述，将一个用户添加到某个角色之中就是为了将对应的权限赋予该用户。在《使用最简洁的代码实现登录、认证和注销》中，我们提供了一个用来演示登录、认证和注销的程序，现在我们在此基础上添加基于“角色授权的部分”。 ASP.NET应用并没有对如何定义授权策略做硬性规定，所以我们完全根据用户具有的任意特性（如性别、年龄、学历、所在地区、宗教信仰、政治面貌等）来判断其是否具有获取目标资源或者执行目标操作的权限，但是针对角色的授权策略依然是最常用的。角色（或者用户组）实际上就是对一组权限集的描述，将一个用户添加到某个角色之中就是为了将对应的权限赋予该用户。在《使用最简洁的代码实现登录、认证和注销》中，我们提供了一个用来演示登录、认证和注销的程序，现在我们在此基础上添加基于“角色授权的部分”。（本文提供的示例演示已经同步到《ASP.NET Core 6框架揭秘-实例演示版》）...

SignalR WebSocket通讯机制

|
By Using Microsoft. AspNetCore.Authorization, Using Microsoft. AspNetCore.SignalR, using System.Threading.Tasks, namespace Server SignalR.Models
| cnblogs.com
1、什么是SignalR ASP.NET SignalR 是一个面向 ASP.NET 开发人员的库，可简化向应用程序添加实时 Web 功能的过程。 实时 Web 功能是让服务器代码在可用时立即将内容推送到连接的客户端，而不是让服务器等待客户端请求新数据。 SignalR使用的三种底层传输技术分别是Web Socket, Server Sent Events 和 Long Polling， 它让你更好的关注业务问题而不是底层传输技术问题。 WebSocket是最好的最有效的传输方式, 如果浏览器或Web服务器不支持它的话(IE10之前不支持Web Socket), 就会降级使用SSE, 实在不行就用Long Polling。 (现在也很难找到不支持WebSocket的浏览器了，所以我们一般定义必须使用WebSocket) 2、我们做一个聊天室，实现一下SignalR前后端通讯 由简入深，先简单实现一下 2.1 服务端Net5 using Microsoft.AspNetCore.Authorization; using Microsoft.AspNetCore.SignalR;...

Enforcing Multiple Authorization Filters in ASP.NET Core

|
By Using Microsoft. AspNetCore.Authorization, using System.Linq, Using Microsoft. AspNetCore.Mvc.Filters
| Blogarama
In ASP.NET Core, Authorization Filters are used to enforce security policies for controllers and actions. They allow developers to control access to specific resources in their application, based on the roles and claims of the current user. A common scenario is to have multiple Authorization filters for a single action, each with different requirements and responsibilities.

| microsoft.com
Read in English Read in English Feedback Edit Twitter LinkedIn Facebook Email Article 09/29/2022 31 minutes to read In this article Underneath the covers, role-based authorization and claims-based authorization use a requirement, a requirement handler, and a preconfigured policy. These building blocks support the expression of authorization evaluations in code. The result is a richer, reusable, testable authorization structure. An authorization policy consists of one or more requirements.

Why Do We Encourage Poor Coding Patterns?

|
By using System.Collections.Generic, using System.Linq, using System.Threading.Tasks, Using Microsoft. AspNetCore.Authorization
| DZone Verified
For what feels like an eternity at this point, we’ve discussed “shifting left” in the SDLC, taking into account security best practices from the start of software development. DevSecOps was a great leap forward, in no small part because of the emphasis on shared responsibility for security, and the power of a security-aware developer to thwart common vulnerabilities as they write code.
