为什么我在NestJS中得到JWTStrategy需要秘密或密钥？

Question

我正在为我的NestJS项目实现验证。我严格按照NestJS文档和 这个 但当我试图启动API时，我仍然得到一个错误。我似乎不知道是什么原因造成的。我试着设置了 secretOrKey 到硬编码字符串，但没有效果，然后我把它移到一个 .env 还是不行。

下面是我的模块代码和JwtStrategy文件。

// AuthModule
@Module({
  imports: [
    ConfigModule.forRoot(),
    UserModule,
    PassportModule.register({ defaultStrategy: 'jwt' }),
    TypeOrmModule.forFeature([Registration]),
    JwtModule.register({
      secretOrPrivateKey: process.env.JWT_SECRET_KEY,
      signOptions: { expiresIn: process.env.JWT_EXPIRES }
    }),
  ],
  controllers: [AuthController],
  providers: [AuthService, LocalStrategy, JwtStrategy],
  exports: [AuthService, LocalStrategy, JwtStrategy]
})
export class AuthModule {}

// JWTStrategy
import { Injectable, UnauthorizedException } from "@nestjs/common";
import { PassportStrategy } from "@nestjs/passport";
import { Strategy, ExtractJwt } from "passport-jwt";
import { AuthService } from "./auth.service";

@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy) {
  constructor(private readonly authService: AuthService) {
    super({
      jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
      passReqToCallback: true,
      secretOrKey: 'test'
    })
  }

  async validate(payload: any, done: Function) {
    const user = await this.authService.validateUserToken(payload)
    if (!user) {
      return done(new UnauthorizedException(), false)
    }

    done(null, user)
  }
}

这是我在终端得到的错误信息

我想明白了问题所在，在我的local.strategy.ts文件中，没有从passport-local导入Strategy类，而是从passport-jwt导入。
