Rytass Utils Member Module

Member Base NestJS Module (會員系統模組)

Overview

@rytass/member-base-nestjs-module 提供完整的 NestJS 會員管理系統，包含 JWT 認證、OAuth2 整合、RBAC+Domain 權限控制（Casbin）和密碼策略管理。

Quick Start

安裝

npm install @rytass/member-base-nestjs-module

基本設定

import { MemberBaseModule } from '@rytass/member-base-nestjs-module';

@Module({
  imports: [
    TypeOrmModule.forRoot({ /* 資料庫配置 */ }),
    MemberBaseModule.forRoot({
      accessTokenExpiration: 900,       // 15 分鐘
      refreshTokenExpiration: 7776000,  // 90 天
      passwordMinLength: 12,
      casbinAdapterOptions: {
        type: 'postgres',
        host: 'localhost',
        // ...
      },
    }),
  ],
})
export class AppModule {}

會員登入

import { MemberBaseService } from '@rytass/member-base-nestjs-module';

@Injectable()
export class AuthService {
  constructor(private readonly memberService: MemberBaseService) {}

  // 基本登入
  async login(account: string, password: string, ip?: string) {
    const tokens = await this.memberService.login(account, password, ip);
    return {
      accessToken: tokens.accessToken,
      refreshToken: tokens.refreshToken,
    };
  }

  // 登入並指定 domain（用於多租戶場景）
  async loginWithDomain(account: string, password: string, domain: string, ip?: string) {
    const tokens = await this.memberService.login(account, password, { domain, ip });
    return tokens;
  }
}

Core Concepts

JWT 認證流程

Client → [Bearer Token] → CasbinGuard → Verify JWT → Extract Payload → Route Handler
                                ↓
                         Check Decorators
                                ↓
                    @IsPublic / @Authenticated / @AllowActions

權限裝飾器

RBAC+Domain 模型

// Casbin 策略格式: [subject, domain, object, action]

// 定義權限: [subject, domain, object, action]
await enforcer.addPolicy('admin-role', 'articles', 'article', 'create');
await enforcer.addPolicy('admin-role', 'articles', 'article', 'delete');

// 指派角色: [member, role, domain]
await enforcer.addGroupingPolicy(memberId, 'admin-role', 'articles');

// 路由保護: @AllowActions 接受 [Subject, Action][] 二元組陣列
@AllowActions([['article', 'create']])
async createArticle() { }

Common Patterns

完整認證設定

MemberBaseModule.forRootAsync({
  imports: [ConfigModule],
  inject: [ConfigService],
  useFactory: async (config: ConfigService) => ({
    accessTokenSecret: config.get('JWT_ACCESS_SECRET'),
    accessTokenExpiration: 900,
    refreshTokenSecret: config.get('JWT_REFRESH_SECRET'),
    refreshTokenExpiration: 7776000,

    // 密碼策略
    passwordMinLength: 12,
    passwordShouldIncludeUppercase: true,
    passwordShouldIncludeLowercase: true,
    passwordShouldIncludeDigit: true,
    passwordShouldIncludeSpecialCharacters: true,
    passwordHistoryLimit: 5,
    passwordAgeLimitInDays: 90,

    // 登入安全
    loginFailedBanThreshold: 5,
    loginFailedAutoUnlockSeconds: 1800,

    // Casbin
    casbinAdapterOptions: {
      type: 'postgres',
      host: config.get('DB_HOST'),
      port: config.get('DB_PORT'),
      username: config.get('DB_USER'),
      password: config.get('DB_PASS'),
      database: config.get('DB_NAME'),
    },
  }),
})

OAuth2 整合

支援三種 OAuth2 Provider 類型：

import { OAuth2Provider, GoogleOAuth2Provider, FacebookOAuth2Provider, CustomOAuth2Provider } from '@rytass/member-base-nestjs-module';

// Google Provider
const googleProvider: GoogleOAuth2Provider = {
  channel: 'google',
  clientId: process.env.GOOGLE_CLIENT_ID!,
  clientSecret: process.env.GOOGLE_CLIENT_SECRET!,
  redirectUri: 'https://app.com/auth/callbacks/google',
  scope: ['profile', 'email'],  // 可選
  getState: () => crypto.randomUUID(),  // 可選
};

// Facebook Provider
const facebookProvider: FacebookOAuth2Provider = {
  channel: 'facebook',
  clientId: process.env.FACEBOOK_APP_ID!,
  clientSecret: process.env.FACEBOOK_APP_SECRET!,
  redirectUri: 'https://app.com/auth/callbacks/facebook',
  scope: ['email', 'public_profile'],
};

// Custom OAuth2 Provider（自訂 OAuth2 服務）
const customProvider: CustomOAuth2Provider = {
  channel: 'line',  // 自訂名稱（非 google/facebook）
  clientId: process.env.LINE_CLIENT_ID!,
  clientSecret: process.env.LINE_CLIENT_SECRET!,
  redirectUri: 'https://app.com/auth/callbacks/line',
  scope: ['profile', 'openid'],  // 必填
  requestUrl: 'https://access.line.me/oauth2/v2.1/authorize',  // 必填
  getAccessTokenFromCode: async (code) => {
    // 實作從 code 取得 access token 的邏輯
    const response = await fetch('https://api.line.me/oauth2/v2.1/token', { /* ... */ });
    return response.access_token;
  },
  getAccountFromAccessToken: async (accessToken) => {
    // 實作從 access token 取得使用者識別的邏輯
    const profile = await fetch('https://api.line.me/v2/profile', { /* ... */ });
    return profile.userId;  // 回傳唯一識別碼
  },
};

// 模組配置
MemberBaseModule.forRoot({
  oauth2Providers: [googleProvider, facebookProvider, customProvider],
  oauth2ClientDestUrl: '/dashboard',
});

內建 OAuth2 Controller 路由：

GET /auth/login/google           // 重導向到 Google OAuth
GET /auth/callbacks/google       // 處理 Google 回調
GET /auth/login/facebook         // 重導向到 Facebook OAuth
GET /auth/callbacks/facebook     // 處理 Facebook 回調
GET /auth/login/:channel         // 自訂 OAuth provider
GET /auth/callbacks/:channel     // 自訂 provider 回調

OAuthService 方法：

注意： OAuthService 未透過 index.ts 導出，僅能透過 NestJS 依賴注入使用。

// OAuthService 透過 DI 注入（不能直接 import）
import { Inject, Injectable } from '@nestjs/common';

@Injectable()
export class AuthController {
  constructor(private readonly oauthService: OAuthService) {}

  // 取得 OAuth 登入 URL
  async getGoogleUrl(): Promise<string> {
    return this.oauthService.getGoogleOAuthLoginUrl();
  }

  async getFacebookUrl(): Promise<string> {
    return this.oauthService.getFacebookOAuthLoginUrl();
  }

  async getCustomUrl(channel: string): Promise<string> {
    return this.oauthService.getCustomOAuthLoginUrl(channel);
  }

  // 處理 OAuth callback（回傳 TokenPairDto & { state?: string }）
  async googleCallback(code: string, state?: string) {
    return this.oauthService.loginWithGoogleOAuth2Code(code, state);
  }

  async facebookCallback(code: string, state?: string) {
    return this.oauthService.loginWithFacebookOAuth2Code(code, state);
  }

  async customCallback(channel: string, code: string, state?: string) {
    return this.oauthService.loginWithCustomOAuth2Code(channel, code, state);
  }
}

OAuth2Provider Type Guards：

注意： 這些 Type Guards 目前未透過 index.ts 導出，若需要使用請在專案中自行定義：

// 自行定義 Type Guards（因未從 package 導出）
type OAuth2Provider = GoogleOAuth2Provider | FacebookOAuth2Provider | CustomOAuth2Provider;

function isGoogleProvider(p: OAuth2Provider): p is GoogleOAuth2Provider {
  return p.channel === 'google';
}
function isFacebookProvider(p: OAuth2Provider): p is FacebookOAuth2Provider {
  return p.channel === 'facebook';
}
function isCustomProvider(p: OAuth2Provider): p is CustomOAuth2Provider {
  return p.channel !== 'google' && p.channel !== 'facebook';
}

自訂會員實體

import { BaseMemberEntity } from '@rytass/member-base-nestjs-module';

@Entity('members')
@ChildEntity()
export class CustomMember extends BaseMemberEntity {
  @Column({ nullable: true })
  displayName?: string;

  @Column({ default: false })
  isVerified: boolean;

  @Column({ type: 'jsonb', nullable: true })
  profile?: Record<string, any>;
}

// 模組配置
MemberBaseModule.forRoot({
  memberEntity: CustomMember,
})

自訂 JWT Payload

MemberBaseModule.forRoot({
  customizedJwtPayload: (member) => ({
    id: member.id,
    account: member.account,
    displayName: member.displayName,
    roles: member.roles,
  }),
})

會員註冊

@Injectable()
export class RegistrationService {
  constructor(private readonly memberService: MemberBaseService) {}

  // 一般註冊
  async register(account: string, password: string) {
    return this.memberService.register(account, password, {
      displayName: 'New User',  // 可傳入自訂欄位
    });
  }

  // 無密碼註冊（系統產生密碼）
  async registerWithoutPassword(account: string) {
    const [member, generatedPassword] = await this.memberService.registerWithoutPassword(account, {
      shouldUpdatePassword: true,  // 預設 true
    });
    // 發送 email 包含臨時密碼
    return member;
  }
}

密碼重設流程

@Injectable()
export class PasswordResetService {
  constructor(private readonly memberService: MemberBaseService) {}

  async requestReset(account: string) {
    const token = await this.memberService.getResetPasswordToken(account);
    // 發送 email 包含 token
    return { message: 'Reset email sent' };
  }

  async resetPassword(token: string, newPassword: string) {
    await this.memberService.changePasswordWithToken(token, newPassword);
    return { message: 'Password changed' };
  }

  // 變更密碼（需舊密碼）
  async changePassword(memberId: string, oldPassword: string, newPassword: string) {
    await this.memberService.changePassword(memberId, oldPassword, newPassword);
    return { message: 'Password changed' };
  }
}

Token 刷新

@Injectable()
export class TokenService {
  constructor(private readonly memberService: MemberBaseService) {}

  async refresh(refreshToken: string, domain?: string) {
    return this.memberService.refreshToken(refreshToken, { domain });
  }
}

解鎖帳號

@Injectable()
export class AdminService {
  constructor(private readonly memberService: MemberBaseService) {}

  // 重設登入失敗次數（解鎖帳號）
  async unlockMember(memberId: string) {
    return this.memberService.resetLoginFailedCounter(memberId);
  }
}

管理員操作 (MemberBaseAdminService)

import { MemberBaseAdminService } from '@rytass/member-base-nestjs-module';

@Injectable()
export class AdminManagementService {
  constructor(private readonly adminService: MemberBaseAdminService) {}

  // 軟刪除會員
  async archiveMember(memberId: string): Promise<void> {
    return this.adminService.archiveMember(memberId);
  }

  // 管理員重設密碼（可跳過密碼策略檢查）
  async resetMemberPassword(
    memberId: string,
    newPassword: string,
    ignorePasswordPolicy?: boolean  // 預設 false
  ) {
    return this.adminService.resetMemberPassword(memberId, newPassword, ignorePasswordPolicy);
  }
}

密碼驗證工具 (PasswordValidatorService)

import { PasswordValidatorService } from '@rytass/member-base-nestjs-module';

@Injectable()
export class PasswordService {
  constructor(private readonly passwordValidator: PasswordValidatorService) {}

  // 產生符合策略的隨機密碼
  generatePassword(): string {
    return this.passwordValidator.generateValidPassword();
  }

  // 檢查密碼是否過期
  checkPasswordExpiry(member: MemberEntity): boolean {
    return this.passwordValidator.shouldUpdatePassword(member);
  }

  // 驗證密碼是否符合策略（支援歷史檢查）
  async validatePassword(password: string, memberId?: string): Promise<boolean> {
    return this.passwordValidator.validatePassword(password, memberId);
  }
}

GraphQL 整合

import { GraphQLModule } from '@nestjs/graphql';
import { GraphQLContextTokenResolver } from '@rytass/member-base-nestjs-module';

@Module({
  imports: [
    GraphQLModule.forRoot({
      context: GraphQLContextTokenResolver,  // 自動提取 Token
      fieldResolverEnhancers: ['guards'],
    }),
    MemberBaseModule.forRoot({ /* ... */ }),
  ],
})
export class AppModule {}

API Reference

詳細 API 文件請參閱 reference.md。

Data Types

TokenPairDto

登入成功後的回傳結構：

interface TokenPairDto {
  accessToken: string;           // JWT Access Token
  refreshToken: string;          // Refresh Token
  shouldUpdatePassword?: boolean; // 密碼是否需要更新（僅啟用密碼過期檢查時返回）
  passwordChangedAt?: string;    // ISO8601 格式，上次密碼更改時間
}

Error Codes

Errors 物件導出

所有錯誤類別透過 Errors 物件統一導出：

import { Errors } from '@rytass/member-base-nestjs-module';

// 使用範例
if (error instanceof Errors.MemberNotFoundError) {
  console.log('會員不存在');
}

// Errors 包含：
// - MemberNotFoundError
// - PasswordDoesNotMeetPolicyError
// - InvalidPasswordError
// - PasswordValidationError
// - InvalidToken
// - MemberAlreadyExistedError
// - PasswordChangedError
// - MemberBannedError
// - PasswordExpiredError
// - PasswordShouldUpdatePasswordError

注意： PasswordInHistoryError 目前未包含在 Errors 物件中，需直接從 ./constants/errors/base.error 導入使用。

Troubleshooting

Token 驗證失敗

1. 確認 accessTokenSecret 一致
2. 檢查 Token 是否過期
3. 驗證 Bearer 格式正確

Casbin 權限不生效

1. 確認 casbinAdapterOptions 配置正確
2. 檢查策略是否正確添加
3. 確認 domain 參數匹配

密碼策略錯誤

錯誤代碼 101: PasswordDoesNotMeetPolicyError

• 檢查密碼長度、大小寫、數字、特殊字符要求
• 使用 PasswordValidatorService.validatePassword() 測試
