Angular 8 配置 oidc

時間  2019-11-08
標籤 angular 配置 oidc 欄目 AngularJS 简体版
原文   原文鏈接

配置相對較爲繁瑣，最後會放上 Github 源碼地址

新建一個 ng 項目

ng new angular-oidccss

進入目錄 cd angular-oidchtml

安裝 oidc-client

npm i oidc-client --save

配置 oidc-client 參數

打開 environment.ts 將下面的代碼覆蓋原來的內容git

import { WebStorageStateStore } from "oidc-client";

export const environment = {
  production: false,
  authConfig: {
    authority: "http://localhost:57001",
    client_id: "query",
    redirect_uri: "http://localhost:4200/login-callback",
    response_type: "id_token token",
    scope: "openid profile",
    post_logout_redirect_uri: "http://localhost:4200",
    accessTokenExpiringNotificationTime: 4,
    filterProtocolClaims: true,
    silentRequestTimeout: 10000,
    loadUserInfo: true,
    userStore: new WebStorageStateStore({ store: window.localStorage }),
  },
};

須要修改的幾個參數:github

  • authority: 認證服務器,須要修改成本身的認證服務器
  • client_id: 客戶端 id ,按照約定修改便可
  • redirect_uri: 認證服務器回調的客戶端頁面
  • post_logout_redirect_uri: 登出回調連接

模塊劃分

這裏咱們把模塊劃分爲2塊: 1) 遊客模塊 2) 用戶模塊npm

默認的殼組件所在的 module 做爲遊客模塊, 另外還須要構建一個用戶模塊sass

遊客模塊

爲了方便理解, 遊客模塊建立一個歡迎頁, 點擊繼續按鈕訪問用戶模塊.服務器

1. 建立一個歡迎頁app

沒什麼特別的做用, 就是爲了方便理解單獨設立的一個交互頁面.less

ng g c public/index

修改 index.component.htmlide

<h3>WELLCOME TO ANGULAR OIDC</h3>
<input type="button" value="visit" (click)="visitAuth()">

修改 index.component.ts

import { Component, OnInit } from "@angular/core";
import { Router } from "@angular/router";

@Component({
  selector: "app-index",
  templateUrl: "./index.component.html",
  styleUrls: ["./index.component.less"],
})
export class IndexComponent implements OnInit {
  constructor(private _router: Router) {}

  ngOnInit() {}

  public visitAuth(): void {
    this._router.navigate(["auth"]);
  }
}

2. 建立一個回調頁

回調頁是用戶 oidc 認證結束後的回調, 起到一個過分的做用(目前先空着)

ng g c public/login-callback

3. 配置路由

打開 app-routing.module.ts, 對照修改

import { NgModule } from "@angular/core";
import { Routes, RouterModule } from "@angular/router";
import { IndexComponent } from "./public/index/index.component";
import { LoginCallbackComponent } from "./public/login-callback/login-callback.component";

const routes: Routes = [
  {
    path: "",
    pathMatch: "full",
    component: IndexComponent,
  },
  {
    path: "login-callback",
    component: LoginCallbackComponent,
  },
];

@NgModule({
  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule],
})
export class AppRoutingModule {}

啓動程序 ng s -o, 這時候已經能看到一點點信息了, 不過尚未 home 路由, 下面來配置一下

用戶模塊

1. 添加一個 auth 模塊

ng g m auth/auth --flat

--flat:不在一個單獨的文件夾建立

2. 將 auth 模塊添加到殼組件

打開 app-module.ts, 主要修改一下內容

import { AuthModule } from "./auth/auth.module";
...

imports: [..., AuthModule],

3. 添加 auth "殼組件"

ng g c auth/auth

4. 添加 auth 模塊的路由

ng g m auth/auth-routing --flat

修改 auth-routing.module.ts 內容以下:

import { NgModule } from "@angular/core";
import { RouterModule, Routes } from "@angular/router";
import { AuthComponent } from "./auth/auth.component";

const routes: Routes = [
  {
    path: "home",
    component: AuthComponent,
  },
];

@NgModule({
  exports: [RouterModule],
})
export class AuthRoutingModule {}

5. 修改 app-routing.module.ts 添加 home 路由

const routes: Routes = [
  {
    path: "",
    pathMatch: "full",
    component: IndexComponent,
  },
  {
    path: "login-callback",
    component: LoginCallbackComponent,
  },
  {
    path: "home",
    component: AuthComponent,
  },
];

ctrl + c -> y 中止以前啓動項目的終端, ng s 從新啓動項目

此時的項目已經能夠從遊客路由跳轉至用戶路由，但咱們是不容許遊客默認訪問用戶路由的, 這時候就應該 守衛(Guard) 登場了。

配置守衛(Guard)

1. 添加 auth.service (認證相關的函數)

ng g s auth/auth --flat

替換 auth.service.ts 內容:

import { Injectable, EventEmitter } from '@angular/core';
import { environment } from 'src/environments/environment';
import { UserManager, User } from 'oidc-client';
import { Observable, from } from 'rxjs';


@Injectable({
  providedIn: 'root'
})
export class AuthService {

  // 大多數 oidc-client 操做都在其中
  private manager: UserManager = new UserManager(environment.authConfig);
  // private manager: UserManager = undefined;

  // 登陸狀態改變事件
  public loginStatusChanged: EventEmitter<User> = new EventEmitter();
  // localStorage 中存放用戶信息的 Key

  private userKey = `oidc.user:${environment.authConfig.authority}:${environment.authConfig.client_id}`;
  // private userKey = `oidc.user:${this._conf.env.authConfig.authority}:${this._conf.env.authConfig.client_id}`;

  constructor() {
    // 若是訪問用的 token 過時，調用 login()
    this.manager.events.addAccessTokenExpired(() => {
      this.login();
    });
  }

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

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

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

  tryGetUser() {

    return from(this.manager.getUser());
  }

  get type(): string {
    return 'Bearer';
  }

  get user(): User | null {
    const temp = localStorage.getItem(this.userKey);
    if (temp) {
      const user: User = JSON.parse(temp);
      return user;
    }
    return null;
  }

  get token(): string | null {
    const temp = localStorage.getItem(this.userKey);
    if (temp) {
      const user: User = JSON.parse(temp);
      return user.access_token;
    }
    return null;
  }

  get authorizationHeader(): string | null {
    if (this.token) {
      return `${this.type} ${this.token}`;
    }
    return null;
  }
}

2. 添加 auth.guard

ng g g auth/auth --flat

選擇 CanActivate

替換 auth.guard.ts 內容:

import { Injectable } from "@angular/core";
import {
  CanActivate,
  CanActivateChild,
  ActivatedRouteSnapshot,
  RouterStateSnapshot,
  UrlTree,
} from "@angular/router";
import { Observable } from "rxjs";
import { map } from "rxjs/operators";
import { AuthService } from "./auth.service";
import { User } from "oidc-client";

@Injectable({
  providedIn: "root",
})
export class AuthGuard implements CanActivate {
  constructor(private _auth: AuthService) {}

  canActivate(
    next: ActivatedRouteSnapshot,
    state: RouterStateSnapshot
  ): Observable<boolean> {
    return this.mapper(this._auth.tryGetUser());
  }

  private mapper = map((user: User) => {
    if (user) return true;
    this._auth.login();
    return false;
  });
}

3. 修改 app-routing.module.ts

import { NgModule } from "@angular/core";
import { RouterModule, Routes } from "@angular/router";
import { AuthComponent } from "./auth/auth.component";
import { C1Component } from "./test/c1/c1.component";
import { C2Component } from "./test/c2/c2.component";

const routes: Routes = [
  {
    path: "home",
    component: AuthComponent,
    children: [
      { path: "c1", component: C1Component },
      { path: "c2", component: C2Component },
    ],
  },
];

@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule],
})
export class AuthRoutingModule {}

4. 修改 login-callback.component.ts 頁

回到成功後，導航到 home 頁，你也能夠寫更多的其餘邏輯。

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

@Component({
  selector: "app-login-callback",
  templateUrl: "./login-callback.component.html",
  styleUrls: ["./login-callback.component.less"],
})
export class LoginCallbackComponent implements OnInit {
  constructor(private _router: Router, private _auth: AuthService) {}

  ngOnInit() {
    this._auth.loginCallBack().subscribe((user: User) => {
      this._router.navigate(["home"]);
    });
  }
}

順便美化一下下樣式

login-callback.component.html:

<div class="callback-bar">
  <span style="margin-left: 10px;">登陸成功，跳轉中...</span>
</div>

login-callback.component.less(我這裏使用的是 less，你的多是 css/scss/sass):

.callback-bar {
    margin: 0px 0px 0px 0px;
    padding: 8px 0px 0px 0px;
    font-size: 24px;
    font-weight: 600px;
    color: white;
    background-color: #3881bf;
    box-shadow: 0px 3px 5px #666;
    height: 50px;
}

再此重啓一下程序（每每一些奇奇怪怪的問題從新啓動後會被解決）。

這時候就已經實現了一個認證的過程，不過 auth 模塊（用戶模塊）只有一個組件，總感受不夠直觀，所以，咱們須要在 auth 模塊添加更多的組件，造成子路由，在觀察功能。

添加 auth 子組件、子路由

修改 auth.component 組件

1. auth.component.html

<div>
  <input type="button" value="c1" (click)="goC1()">
  <input type="button" value="c2" (click)="goC2()">
</div>

<div>
  <router-outlet></router-outlet>
</div>

2. auth.component.ts

import { Component, OnInit } from "@angular/core";
import { Router } from "@angular/router";

@Component({
  selector: "app-auth",
  templateUrl: "./auth.component.html",
  styleUrls: ["./auth.component.less"],
})
export class AuthComponent implements OnInit {
  constructor(private _router: Router) {}

  ngOnInit() {}

  public goC1(): void {
    this._router.navigate(["home/c1"]);
  }

  public goC2(): void {
    this._router.navigate(["home/c2"]);
  }
}

新建子路由

2. 添加 c一、c2 子組件

ng g c auth/test/c1
ng g c auth/test/c2

保持默認內容便可。

3. 修改 auth-routing.module.ts

import { NgModule } from "@angular/core";
import { RouterModule, Routes } from "@angular/router";
import { AuthComponent } from "./auth/auth.component";
import { C1Component } from "./test/c1/c1.component";
import { C2Component } from "./test/c2/c2.component";

const routes: Routes = [
  {
    path: "home",
    component: AuthComponent,
    children: [
      { path: "c1", component: C1Component },
      { path: "c2", component: C2Component },
    ],
  },
];

@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule],
})
export class AuthRoutingModule {}

重啓項目，這時候獲得一個錯誤信息：

Error: Template parse errors:
'router-outlet' is not a known element:

這表示 auth 模塊沒有引入 RouterModule，實際上是咱們的 auth.module.ts 沒有引入 auth-routing.module.ts 致使的（routing 中有引入 RouterModule）

修改 auth.module.ts:

...
import { AuthRoutingModule } from './auth-routing.module';

@NgModule({
  ...
  imports: [..., AuthRoutingModule],
})

重啓項目，能夠看到如今基本功能都已經實現了，不過還差一個退出功能。

退出登陸

1. 修改 auth.component.html

<div>
  <input type="button" value="c1" (click)="goC1()">
  <input type="button" value="c2" (click)="goC2()">
  <input type="button" value="exit" (click)="exit()">
</div>

<div>
  <router-outlet></router-outlet>
</div>

2. 修改 auth.component.ts

import { Component, OnInit } from "@angular/core";
import { Router } from "@angular/router";
import { AuthService } from "../auth.service";

@Component({
  selector: "app-auth",
  templateUrl: "./auth.component.html",
  styleUrls: ["./auth.component.less"],
})
export class AuthComponent implements OnInit {
  constructor(private _router: Router, private _auth: AuthService) {}

  ngOnInit() {}

  public goC1(): void {
    this._router.navigate(["home/c1"]);
  }

  public goC2(): void {
    this._router.navigate(["home/c2"]);
  }

  public exit(): void {
    this._auth.logout();
  }
}

重啓測試，退出成功！

訪問 /home 自動跳轉登陸，沒問題。

訪問 /home/c1 竟然跳過了認證，直接進來了！

形成這個問題的緣由是可是咱們的守衛添加的方式是 canActivate，canActivate只會保護本路由，而不會保護其子路由。所以，咱們還須要保護子路由！

保護子路由

1. 修改 auth.guard.ts

import { Injectable } from "@angular/core";
import {
  CanActivate,
  CanActivateChild,
  ActivatedRouteSnapshot,
  RouterStateSnapshot,
  UrlTree,
} from "@angular/router";
import { Observable } from "rxjs";
import { map } from "rxjs/operators";
import { AuthService } from "./auth.service";
import { User } from "oidc-client";

@Injectable({
  providedIn: "root",
})
export class AuthGuard implements CanActivate, CanActivateChild {
  constructor(private _auth: AuthService) {}

  canActivate(
    next: ActivatedRouteSnapshot,
    state: RouterStateSnapshot
  ): Observable<boolean> {
    return this.mapper(this._auth.tryGetUser());
  }

  canActivateChild(
    next: ActivatedRouteSnapshot,
    state: RouterStateSnapshot
  ):
    | Observable<boolean | UrlTree>
    | Promise<boolean | UrlTree>
    | boolean
    | UrlTree {
    return this.mapper(this._auth.tryGetUser());
  }

  private mapper = map((user: User) => {
    if (user) return true;
    this._auth.login();
    return false;
  });
}

2. 修改 auth-routing.module.ts
主要修改代碼以下：

import { AuthGuard } from "./auth.guard"; // <- here

const routes: Routes = [
  {
    path: "home",
    component: AuthComponent,
    canActivateChild: [AuthGuard], // <- here
    children: [
      { path: "c1", component: C1Component },
      { path: "c2", component: C2Component },
    ],
  },
];

重啓項目，再此訪問 '/home/c1'，成功跳轉，訪問 '/home'，一樣成功跳轉。
