我有一个使用JWT的无状态身份验证模型的新SPA。我经常被要求引用OAuth进行身份验证流程，比如要求我为每个请求发送“承载令牌”，而不是简单的令牌头，但我确实认为OAuth比简单的基于JWT的身份验证要复杂得多。主要的区别是什么，我应该让JWT身份验证像OAuth一样吗?
我还使用JWT作为我的XSRF- token来防止XSRF，但我被要求将它们分开?我应该把它们分开吗?这里的任何帮助都将受到感谢，并可能为社区提供一套指导方针。

找出JWT和OAuth之间的主要区别
OAuth 2.0定义了一个协议，JWT定义了一个令牌格式。 OAuth既可以使用JWT作为令牌格式，也可以使用访问令牌作为承载令牌。 OpenID连接大多使用JWT作为令牌格式。

Firstly, we have to differentiate JWT and OAuth. Basically, JWT is a token format. OAuth is an authorization protocol that can use JWT as a token. OAuth uses server-side and client-side storage. If you want to do real logout you must go with OAuth2. Authentication with JWT token can not logout actually. Because you don't have an Authentication Server that keeps track of tokens. If you want to provide an API to 3rd party clients, you must use OAuth2 also. OAuth2 is very flexible. JWT implementation is very easy and does not take long to implement. If your application needs this sort of flexibility, you should go with OAuth2. But if you don't need this use-case scenario, implementing OAuth2 is a waste of time.
XSRF令牌总是在每个响应头中发送给客户端。CSRF令牌是否在JWT令牌中发送并不重要，因为CSRF令牌本身是安全的。因此，在JWT中发送CSRF令牌是不必要的。
OAuth 2.0定义了一个协议，即指定了令牌如何传输，JWT定义了令牌格式。
OAuth 2.0和“JWT身份验证”在客户端向资源服务器提供令牌的(第二)阶段具有类似的外观:令牌在头文件中传递。
但是“JWT身份验证”不是一个标准，并且没有指定客户端首先如何获得令牌(第一阶段)。这就是OAuth复杂性的来源:它还定义了客户端从所谓的授权服务器获取访问令牌的各种方式。
因此，真正的区别在于JWT只是一种令牌格式，OAuth 2.0是一种协议(可以使用JWT作为令牌格式)。
Jwt是一组用于发布和验证已签名访问令牌的严格指令。令牌包含应用程序用来限制用户访问的声明
OAuth2 on the other hand is not a protocol, its a delegated authorization framework. think very detailed guideline, for letting users and applications authorize specific permissions to other applications in both private and public settings. OpenID Connect which sits on top of OAUTH2 gives you Authentication and Authorization.it details how multiple different roles, users in your system, server side apps like an API, and clients such as websites or native mobile apps, can authenticate with each othe
注意oauth2可以与jwt一起工作，实现灵活，可扩展到不同的应用程序
JWT tokens require, at most, a one-time communication between the resource server and the authorization server at runtime. The resource server needs to request the authorization server for the public key to decrypt the JWT tokens. This can be done at resource server startup. This can even be stored in the resource server in a properties file avoiding the query at all. OAuth2 solve a problem that user wants to access the data using client software like browser-based web apps, native mobile apps, or desktop apps. OAuth2 is just for authorization, client software can be authorized to access the resources on behalf of end-user using an access token. OAuth2 can be used with JWT tokens or access token which is a bearer token.
