複数のプロジェクトで使用する分散認証ライブラリを実装したいと考えています。ライブラリは JWT 認証方式を実装する必要があります。コードは次のとおりです。

jwt.strategy.ts

import {ExtractJwt, Strategy} from 'passport-jwt';
import {PassportStrategy} from '@nestjs/passport';
import {Injectable} from '@nestjs/common';
import {JwtPayload, User} from './interfaces';
import {ConfigService} from "./config.service";

@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy, 'jwt') {
  constructor(private readonly configService: ConfigService) {
    super({
      jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
      secretOrKey: configService.get('secretOrPrivateKey'),
    });
  }

  async validate(payload: JwtPayload): Promise<User> {
     return {
      uuid: payload.uuid,
      email: payload.email,
    }
  }
}

jwt.auth.module.ts:

import {Module, DynamicModule} from '@nestjs/common';
import {JwtModule} from '@nestjs/jwt';
import {JwtStrategy} from './jwt.strategy';
import {PassportModule} from '@nestjs/passport';
import {ConfigService} from "./config.service";
import {JwtOptions} from "./interfaces/jwt.options";

@Module({
})

export class JwtAuthModule {
  static forRoot(jwtOptions): DynamicModule {
    return {
      module: JwtAuthModule,
      imports: [
        // JwtModule.register(jwtOptions),
        // PassportModule.register({defaultStrategy: 'jwt'}),
      ],
      providers: [
        JwtStrategy,
        {
          provide: ConfigService,
          useValue: new ConfigService(jwtOptions),
        }
      ],
      exports: [ConfigService, JwtStrategy]
    };
  }
}

そして私はこれを私の中にインポートしましたapp.module.ts:

import { Module, NestModule, HttpModule } from '@nestjs/common';
import { MongooseModule } from '@nestjs/mongoose';
import { environment } from './environments';
import { AuthModule } from './auth/auth.module';
import { PermissionModule } from './permission/permission.module';
import {JwtAuthModule} from '@pe/nest-kit';
import {JwtModule} from '@nestjs/jwt';
import {PassportModule} from '@nestjs/passport';

@Module({
  imports: [
    JwtModule.register(environment.jwtOptions),
    PassportModule.register({defaultStrategy: 'jwt'}),
    JwtAuthModule.forRoot(environment.jwtOptions),
    HttpModule,
    AuthModule,
    PermissionModule,
    MongooseModule.forRoot(environment.mongodb),
  ],
})
export class ApplicationModule implements NestModule {
  configure() {
  }
}

ただし、プロジェクトの URL を開こうとするたびに、エラーが発生します。

[Nest] 27645 - 24.10.2018、15:23:26 [ExceptionsHandler] 未知の認証戦略 "jwt" +4119ms エラー: 試行時の未知の認証戦略 "jwt" (/home/user/workspace/permissions/node_modules/passport/lib /middleware/authenticate.js:187:37) 認証時 (/home/user/workspace/permissions/node_modules/passport/lib/middleware/authenticate.js:363:7) で Promise (/home/user/workspace/permissions) /node_modules/@nestjs/passport/dist/auth.guard.js:83:3) /home/user/workspace/permissions/node_modules/@nestjs/passport/dist/auth.guard.js の新しい Promise () で: MixinAuthGuard で 75:83。(/home/user/workspace/permissions/node_modules/@nestjs/passport/dist/auth.guard.js:47:36) Generator.next () at /home/user/workspace/permissions/node_modules/@nestjs/パスポート/dist/auth.guard.js:19:

私は何を間違っていますか？

これは github の私のコードです: https://github.com/riadhriadh/prototype_nestjs/tree/dev

jwt.strategy.ts で

    import * as passport from 'passport';
    import { ExtractJwt, Strategy } from 'passport-jwt';
    import { Injectable } from '@nestjs/common';
    import { AuthService } from '../auth.service';
    const  config_projet =require("./projet_config");
    @Injectable()
    export class JwtStrategy extends Strategy {
      constructor(private readonly authService: AuthService) {
        super(
          {
            jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
            passReqToCallback: true,
            secretOrKey: config_projet.secret,
          },
          async (req, payload, next) => await this.verify(req, payload, next)
        );
        passport.use(this);
      }

      public async verify(req, payload, done) {
        const isValid = await this.authService.validateUser(payload);
        if (!isValid) {
          return done('Unauthorized', false);
        }
        done(null, payload);
      }
}

===================

in : auth.service.ts

import { Injectable } from '@nestjs/common';
import * as jwt from 'jsonwebtoken';
import { UsersService } from 'users/users.service';
const  config_projet =require("../projet_config");
var fs = require('fs');
@Injectable()
export class AuthService {

  constructor(private readonly usersService: UsersService) { }


  async createToken(email: string) {
    const expiresIn = 6000 * 60;
    const secretOrKey = fs.readFileSync("./key.pem");;
    const user = { email };

     const token = jwt.sign(user, secretOrKey,   { audience: 'urn:foo' });


    return { expires_in: expiresIn, token };
  }
  async validateUser(signedUser): Promise<boolean> {
    if (signedUser && signedUser.email) {
      return Boolean(this.usersService.getUserByEmail(signedUser.email));
    }

    return false;
  }
}

==============================

in : auth.controller.ts

================================

import { Controller, Post, HttpStatus, HttpCode, Get, Response, Body } from '@nestjs/common';
import { AuthService } from './auth.service';
import { UsersService } from 'users/users.service';
import { User } from 'users/user.entity';

@Controller("auth")
export class AuthController {
    constructor(
        private readonly authService: AuthService,
        private readonly userService: UsersService
    ) {}
    @Post('login')
    async loginUser(@Response() res: any, @Body() body: User) {
      if (!(body && body.email && body.password)) {
        return res.status(HttpStatus.FORBIDDEN).json({ message: 'Email and password are required!' });
      }

      const user = await this.userService.getUserByEmail(body.email);

      if (user) {
        if (await this.userService.compareHash(body.password, user.password)) {
          return res.status(HttpStatus.OK).json(await this.authService.createToken(user.email));
        }
      }

      return res.status(HttpStatus.FORBIDDEN).json({ message: 'Email or password wrong!' });
    } 
    @Post('register')
    async registerUser(@Response() res: any, @Body() body: User) {

      }

      let user = await this.userService.getUserByEmail(body.email);

      if (user) {
        return res.status(HttpStatus.FORBIDDEN).json({ message: 'Email exists' });
      } else {
        let userSave = await this.userService.create(body);
       if(userSave){
         body.password=undefined;
       }
        return res.status(HttpStatus.OK).json(userSave);
      }
    }
}

解決しました。PHP では、プロジェクト全体に対して 1 つの依存関係ツリーがあります。npm では、各パッケージに独自の依存関係サブツリーがあります。例:
--passport
--@pe/nest-kit
----passport Nest
-kit は から----passportのオブジェクトを使用しますが、ルート プロジェクトは同じ名前のタイプのオブジェクトを使用しますが、実際、これは nodejs コンパイラの別のタイプです。解決策は、@nestjs/passport から @pe/nest-kit を介して AuthGuard を再エクスポートすることです。
