                         标签:通过   一个   ipa   lte   依赖   sea   out   方便   tde    Microsoft.Authentication的使用方法在2.0中发生了比较大的变化,在1.1中认证配置是在Configure中完成。 UseJwtBearerAuthentication其实是添加了一个中间件   而在2.0中,认证配置则是在ConfigureServices中完成,并且通过Scheme-Handler的形式来实现多种认证方案的策略式选择。          也就是说,1.1的时候我们使用不同的认证方案时,是使用不同的中间件来实现认证,而2.0则刚好反过来,官方实现了一个统一的认证中间件,在中间件里获取对应的Scheme的Handler,然后调用Handler来完成认证过程。 在2.0中实现自己的认证方案非常方便——自己实现一个AuthenticationSchemeOptions和一个AuthenticationHandler,然后通过AddScheme注入并指定Scheme就可以了。   以官方JwtBearerAuthentication为例: 源码在此:https://github.com/aspnet/Security/tree/rel/2.0.0-preview1/src/Microsoft.AspNetCore.Authentication.JwtBearer 在ConfigureServices中调用AddJwtBearerAuthentication,其实是调用了AddScheme,authenticationScheme是JwtBearerDefaults.AuthenticationScheme。 .Net Core 2.0 preview1实现自定义认证方案 标签:通过   一个   ipa   lte   依赖   sea   out   方便   tde    原文地址:http://www.cnblogs.com/zonciu/p/7141139.htmlpublic void ConfigureServices(IServiceCollection services)
