前言
.net core 出来有一时间了,这段时间也一直在做技术准备,目前想做一个单点登录(SSO)系统,在这之前用.net时我用习惯了machineKey ,也顺手在.net core 中尝试了一上,结果发现不好使了,也不起作用,于是开始了网上学习。
实现方法
功夫不负有心人,网上高人还是多,在github.com上面ISSUES中也有人在讨论此问题,于是找到代码尝试,结果实现了。
直接上代码,我们需要先封装一个XmlRepository,Key的格式如下:

public async void Login() { if (!HttpContext.User.Identities.Any(identity => identity.IsAuthenticated)) { var user = new ClaimsPrincipal( new ClaimsIdentity( new [] { new Claim(ClaimTypes.Name, "bob" ) }, CookieAuthenticationDefaults.AuthenticationScheme)); await HttpContext.Authentication.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, user); HttpContext.Response.ContentType = "text/plain" ; await HttpContext.Response.WriteAsync( "Hello First timer" ); } else { HttpContext.Response.ContentType = "text/plain" ; await HttpContext.Response.WriteAsync( "Hello old timer" ); } } |
注意
C:\keys\key.xml 这个文件路径可以更改,还有就是也可用共享目录或数据库来实现统一管理
到此可以登录试一下。
以上所述是小编给大家介绍的.net core 1.0 实现单点登录负载多服务器的全部叙述,希望对大家有所帮助!
