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);

IUserService

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
