使用Angular SPA应用程序与IdentityServer4进行通信以进行身份验证/授权，以接收令牌，然后与Web API进行通信 [英] Talking to IdentityServer4 with an Angular SPA application for authentication/authorization receiving a token then talking to Web API
问题描述
我有一个asp.net核心Web API.我目前正在使用Angular 4应用直接对其进行呼叫.
I have an asp.net core Web API. I am currently making calls directly to it using an Angular 4 app.
我现在要添加身份验证和授权层.
I now want to add authentication and authorization layer.
我想通过将另一个类型为ASP.NET Core MVC(带有个人用户帐户)的项目(严格用于auth)添加到我的解决方案中，然后向其中添加IdentityServer4.该计划是使用现有的身份表存储用户，角色等.
I would like to do this by adding another project (strictly for auth) of type : ASP.NET Core MVC (w/ Individual User Accounts) to my solution and then adding IdentityServer4 to it. The plan is to use the existing Identity tables to store users, roles, etc.
一旦完成所有设置，我对Angular 4 SPA应用程序或任何其他第三方如何通过IdentityServer应用程序进行身份验证感到有些困惑.我假设这会返回某种令牌.然后继续使用该令牌调用我的原始Web API项目(即GetCustomers()).
Once this is all setup I am a bit confused about how my Angular 4 SPA app or any other third party authenticates through the IdentityServer app. I would assume this then returns a token of some sort. Then proceeds to make calls to my original Web API project (i.e. GetCustomers()) with that token.
从研究中我发现，我似乎唯一需要做的另一件事就是ASP.NET Core中的JWT承载身份验证.
From the research I did it looks like the only other thing that I need is JWT bearer authentication in ASP.NET Core.
有人可以向我提供一些有关如何进行整个过程的链接/信息.还没有找到贯穿整个过程的优质视频.另外，请确认我正在谈论的上述模式听起来正确.
Can someone please provide me with some links/information on how to go about this entire process. Haven't found any good videos that go through the entire thing. Also, please confirm that the above pattern I am talking about sounds correct.
推荐答案
Identity Server具有不同的flows/grant types，您所说的称为
Identity Server has different flows/grant types, the one you talking about called implicit in that case Identity Server will return a jwt token so you have to be storing that jwt token on a client and then attaching that token to request header when requesting your secure webapi routes.
