尾巴之上冒起了一阵火焰,经过了那么多天的训练战斗,黑亚古兽体内的黑暗力量已经越来越强了,小型火焰也随之提升,蓝幽幽的火焰散发着极高的温度,有着伤口的地方被这么一烧顿时受伤不浅。

下面将开发登陆和授权的部分, 这里要用到identity server 4.

在VS解决方案中设置多个项目同时启动:

AspNetIdentityAuthorizationServer就是authorization server. 它的地址是 http://localhost:5000

CoreApi.Web作为api, 都已经配置好了.它的地址是 http://localhost:5001

Login 登陆

由于我们使用的是Identity Server 4的登录页面, 所以angular项目里面无需登录页面, 把login相关的文件删除...........

登陆需要使用到oidc-client.js所以通过npm安装:

npm install --save oidc-client

Auth Service

需要登陆服务 auth.service:

ng g s services/auth

打开auth.services.ts:

import { Injectable, OnInit, EventEmitter } from "@angular/core";
import { Observable } from "rxjs/Observable";
import { User, UserManager, Log } from "oidc-client";
import "rxjs/add/observable/fromPromise";

const config: any = {
  authority: "http://localhost:5000",
  client_id: "corejs",
  redirect_uri: "http://localhost:4200/login-callback",
  response_type: "id_token token",
  scope: "openid profile coreapi",
  post_logout_redirect_uri: "http://localhost:4200/index.html",
};
Log.logger = console;
Log.level = Log.DEBUG;

@Injectable()
export class AuthService implements OnInit {

  private manager: UserManager = new UserManager(config);
  public loginStatusChanged: EventEmitter<User>;

  constructor() {
    this.loginStatusChanged = new EventEmitter();
  }

  ngOnInit() {

  }

  login() {
    this.manager.signinRedirect();
  }

  loginCallBack() {
    return Observable.create(observer => {
      Observable.fromPromise(this.manager.signinRedirectCallback())
        .subscribe(() => {
          this.tryGetUser().subscribe((user: User) => {
            this.loginStatusChanged.emit(user);
            observer.next(user);
            observer.complete();
          }, e => {
            observer.error(e);
          });
        });
    });
  }

  checkUser() {
    this.tryGetUser().subscribe((user: User) => {
      this.loginStatusChanged.emit(user);
    }, e => {
      this.loginStatusChanged.emit(null);
    });
  }

  private tryGetUser() {
    return Observable.fromPromise(this.manager.getUser());
  }

  logout() {
    this.manager.signoutRedirect();
  }
}

config是针对identity server 4服务器的配置, authorization server的地址是 http://localhost:5000, 登陆成功后跳转后来的地址是: http://localhost:4200/login-callback

其中的UserManager就是oidc-client里面的东西, 它负责处理登录登出和获取当前登录用户等操作.

这里login()方法被调用后会直接跳转到 authorization server的登录页面.

登录成功后会跳转到一个callback页面, 里面需要调用一个callback方法, 这就是loginCallback()方法.

loginStatusChanged是一个EventEmitter, 任何订阅了这个事件的component, 都会在登录用户变化时(登录/退出)触发component里面自定义的事件.

logout()是退出, 调用方法后也会跳转到authorization server的页面.

最后别忘了在app.module里面注册:

  providers: [
    ClientService,
    AuthService
  ],

登陆成功后跳转回掉页面 

建立一个跳转回掉的component和路由:

ng g c components/loginCallback

修改app.module的路由:

const appRoutes: Routes = [
  { path: "", component: DashboardComponent },
  { path: "login-callback", component: LoginCallbackComponent },
  { path: "register", component: RegisterComponent },
  { path: "add-client", component: AddClientComponent },
  { path: "client/:id", component: ClientDetailsComponent },
  { path: "edit-client/:id", component: EditClientComponent }
];

打开login-callback.component.ts:

import { Component, OnInit } from "@angular/core";
import { AuthService } from "../../services/auth.service";
import { Router } from "@angular/router";
import { User } from "oidc-client";

@Component({
  selector: "app-login-callback",
  templateUrl: "./login-callback.component.html",
  styleUrls: ["./login-callback.component.css"]
})
export class LoginCallbackComponent implements OnInit {

  constructor(
    private authService: AuthService,
    private router: Router
  ) { }

  ngOnInit() {
    this.authService.loginCallBack().subscribe(
      (user: User) => {
        console.log("login callback user:", user);
        if (user) {
          this.router.navigate(["/"]);
        }
      }
    );
  }

}

这里主要是调用oidc的回掉函数. 然后跳转到主页.

html:

<p>
  登录成功!
</p>

这个html, 基本是看不见的.

修改Navbar

navbar.component.html:

<nav class="navbar navbar-expand-md navbar-light bg-light">
  <div class="container">
    <a class="navbar-brand" href="#">Client Panel</a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarsExampleDefault" aria-controls="navbarsExampleDefault"
      aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>

    <div class="collapse navbar-collapse" id="navbarsExampleDefault">
      <ul class="navbar-nav mr-auto">
        <li *ngIf="isLoggedIn" class="nav-item">
          <a class="nav-link" href="#" routerLink="/">Dashboard </a>
        </li>
      </ul>
      <ul class="navbar-nav ml-auto">
        <li *ngIf="!isLoggedIn" class="nav-item">
          <a class="nav-link" href="#" routerLink="/register">Register </a>
        </li>
        <li *ngIf="!isLoggedIn" class="nav-item">
          <a class="nav-link" href="#" (click)="login()">Login </a>
        </li>
        <li *ngIf="isLoggedIn" class="nav-item">
          <a class="nav-link" href="#" (click)="logout()">Logout </a>
        </li>
      </ul>
    </div>
  </div>
</nav>
<br>

主要是检查是否有用户登陆了, 有的话不显示注册和登陆链接, 并且显示退出链接按钮. 没有的话, 则显示注册和登录.

navbar.component.ts:

import { Component, OnInit } from "@angular/core";
import { Router } from "@angular/router";
import { AuthService } from "../../services/auth.service";
import "rxjs/add/operator/map";
import { User } from "oidc-client";
import { FlashMessagesService } from "angular2-flash-messages";

@Component({
  selector: "app-navbar",
  templateUrl: "./navbar.component.html",
  styleUrls: ["./navbar.component.css"]
})
export class NavbarComponent implements OnInit {

  public isLoggedIn: boolean;
  public loggedInUser: User;

  constructor(
    private authService: AuthService,
    private router: Router,
    private flashMessagesService: FlashMessagesService
  ) { }

  ngOnInit() {
    this.authService.loginStatusChanged.subscribe((user: User) => {
      this.loggedInUser = user;
      this.isLoggedIn = !!user;
      if (user) {
        this.flashMessagesService.show("登陆成功", { cssClass: "alert alert-success", timeout: 4000 });
      }
    });
    this.authService.checkUser();
  }

  login() {
    this.authService.login();
  }

  logout() {
    this.authService.logout();
  }

}

在ngOnInit里面订阅authservice的那个登录状态变化的事件. 以便切换导航栏的按钮显示情况.

angular的部分先到这, 然后要

修改一个identity server的配置:

在VS2017打开AspNetIdentityAuthorizationServer这个项目的Config.cs文件, 看GetClients()那部分, 里面有一个Client是js client, 我们就用这个....

// JavaScript Client
                new Client
                {
                    ClientId = CoreApiSettings.Client.ClientId,
                    ClientName = CoreApiSettings.Client.ClientName,
                    AllowedGrantTypes = GrantTypes.Implicit,
                    AllowAccessTokensViaBrowser = true,

                    RedirectUris =           { CoreApiSettings.Client.RedirectUris },
                    PostLogoutRedirectUris = { CoreApiSettings.Client.PostLogoutRedirectUris },
                    AllowedCorsOrigins =     { CoreApiSettings.Client.AllowedCorsOrigins },

                    AllowedScopes =
                    {
                        IdentityServerConstants.StandardScopes.OpenId,
                        IdentityServerConstants.StandardScopes.Profile,
                        CoreApiSettings.CoreApiResource.Name
                    }
                }

打开CoreApiSettings, 它在SharedSettings这个项目里面:

namespace SharedSettings.Settings
{
    public class CoreApiSettings
    {
        #region CoreApi

        public static string AuthorizationServerBase = "http://localhost:5000";
        public static string CorsPolicyName = "default";
        public static string CorsOrigin = "http://localhost:4200";
        public static (string Name, string DisplayName) CoreApiResource = ("coreapi", "Core APIs");
        public static (string ClientId, string ClientName, string RedirectUris, string PostLogoutRedirectUris, string AllowedCorsOrigins) Client =
            ("corejs", "Core Javascript Client", "http://localhost:4200/login-callback", "http://localhost:4200/index.html", "http://localhost:4200");

        #endregion
    }
}

把相应的地址改成和angular auth.service里面config一样的地址才能工作.

这里面使用了C# 7的命名Tuple, 非常好用.

差不多可以了, 运行VS. 同时运行angular项目:

1. 首次浏览:

2. 点击登陆:

点击登陆就跳转到authorization server的登录页面了, 你在这里需要注册一个用户.....

然后输入用户名密码登陆.

3.同意授权

点击yes 同意授权.

4.跳转回angular页面:

首先跳转回的是angular的login-callback路由, 然后瞬间回到了主页:

5. 刷新, 还是可以取得到登录的用户.

但是如果再打开一个浏览器实例就无法取得到登陆用户了, oidc应该是把登陆信息存到了session storage里面.

打开浏览器F12--Application:

可以看到在session storage里面确实有东西, 而 localstorage里面却没有.

今天比较忙, 先写到这... 估计还得写一篇....
