一步一步学习IdentityServer3 (7)
在介绍自定义用户服务之前先对IdentityServerServiceFactory说明下 Idr3的服务工厂
下面有很多idr3提供的接口服务,
如:ViewService、UserService、ClientStore 等很多,可以做很多的事情
其实它承载的不光是自身的接口服务,其实还提供了 服务注册 DI ,我们可以注册自己的接口服务实现
自定义用户服务只需要去实现 IUserService接口就行了
factory.UserService = new Registration<IUserService, IdrConfig.UserServices>();
去看下IUserService接口中的方法

// // 摘要: // This method gets called when the user uses an external identity provider to authenticate. // The user's identity from the external provider is passed via the `externalUser` // parameter which contains the provider identifier, the provider's identifier for // the user, and the claims from the provider for the external user. // // 参数: // context: // The context. Task AuthenticateExternalAsync(ExternalAuthenticationContext context); // // 摘要: // This method gets called for local authentication (whenever the user uses the // username and password dialog). // // 参数: // context: // The context. Task AuthenticateLocalAsync(LocalAuthenticationContext context); // // 摘要: // This method is called whenever claims about the user are requested (e.g. during // token creation or via the userinfo endpoint) // // 参数: // context: // The context. Task GetProfileDataAsync(ProfileDataRequestContext context); // // 摘要: // This method gets called whenever identity server needs to determine if the user // is valid or active (e.g. if the user's account has been deactivated since they // logged in). (e.g. during token issuance or validation). // // 参数: // context: // The context. Task IsActiveAsync(IsActiveContext context); // // 摘要: // This method is called prior to the user being issued a login cookie for IdentityServer. // // 参数: // context: // The context. Task PostAuthenticateAsync(PostAuthenticationContext context); // // 摘要: // This method gets called before the login page is shown. This allows you to determine // if the user should be authenticated by some out of band mechanism (e.g. client // certificates or trusted headers). // // 参数: // context: // The context. Task PreAuthenticateAsync(PreAuthenticationContext context); // // 摘要: // This method gets called when the user signs out. // // 参数: // context: // The context. Task SignOutAsync(SignOutContext context);
我们在自己定义的 UserServices中去实现这些接口方法
OwinContext ctx;
//修改 这里依赖我们注册的接口服务
ILYMUser _userServices;
public UserServices(OwinEnvironmentService owinEnv,ILYMUser userServices) {
ctx = new OwinContext(owinEnv.Environment);
_userServices=userServices;
}
到了这一步,其实只是去实现它的接口,在接口方法实现中我们要用自己的接口服务怎么办呢?
其实只需要在factory上注册自己的 服务接口就行了,然后在创建UserServices 构造函数是依赖我们之前注册的自定义服务接口就ok了
factory.Register(new Registration<ILYMUser, LYMUser>()); factory.UserService = new Registration<IUserService, IdrConfig.UserServices>();
这里的ILYMUser、LYMUser自定的接口服务,定义好登录相关方法,在UserServices中本地身份验证的中实现先关业务逻辑就ok
AuthenticateLocalAsync:当用户使用该方法时,该方法将调用本地身份验证 用户名和密码对话框
Tips:这里Owin中间件上下文对象需要创建idr3的环境变量,可以扩展提交一些其他授权参数
