Ocelot统一权限验证

Ocelot作为网关，可以用来作统一验证，接上一篇博客，我们继续

前一篇，我们创建了OcelotGateway网关项目，DemoAAPI项目，DemoBAPI项目，为了验证用户并分发Token，现在还需要添加AuthenticationAPI项目，也是asp.net core web api项目，整体思路是，当用户首次请求（Request）时web服务，网关会判断本请求有无Token，并是否正确，如果没有或不正确，就会反回401 Unauthorized；如果请求调用登录，正确输入用户名或密码，AuthenticationAPI会验证并分发Token；当客户端带上Token再次访问web服务时，网关就会放过本请求，当请求到达web服务时，web服务要对本Token进行授权验证，如果有访问请求的地址，会成功返回应答，负责会提示没有权验，所以只要具有正确的Token，应答返回都是200 OK，因为Token正确，只是没有权限访问请求的内容。
下面创建最重要的一个项目Ocelot.JWTAuthorizePolicy，选.NET Standard的类库作为项目模板创建本项目，本项目的作用是为网关项目（OcelotGateway），web服务项目（DemoAAPI和DemoBAPI），和AuthenticationAPI提供注入JWT或自定义策略的API，关于自定义策略，可参考（http://www.cnblogs.com/axzxs2001/p/7530929.html）
本项目中的组成部分：
