secretOrPrivateKey必须有一个值(硬编码秘密的\没有未定义的值)

Question

PS :我测试了这些：Error: secretOrPrivateKey must have a value

我有在另一个项目中工作的这些代码，我将它们完全复制-粘贴到另一个具有相同依赖关系版本的新项目中，它显示了这个错误。当我像这样调用符号函数时，会发生错误：

await this._jwtTokenService.signAsync(user),

在构造函数中注入_jwtTokenService，如下所示：

  constructor(
private _jwtTokenService: JwtService,
) {}

我以前看到过这个错误，但修复方法是在jwtModule.register函数中注入“秘密”，如下所示：

JwtModule.registerAsync({
  imports: [ConfigModule],
  useFactory: async (configService: ConfigService) => {
    return {
      secret: 'secret',
    };
  },
  inject: [ConfigService],
}), `

但是现在不行了，除非我对符号函数这样做

await this._jwtTokenService.signAsync(user, {secret : 'secret'}),

当我打印_jwtTokenService以查看它所继承的值时，我看到它有空的options对象：

JwtService {
 options: {},
 logger: Logger { context: 'JwtService', options: {} }
  }

例如，我尝试将其传递到寄存器函数中：

  signOptions: { expiresIn: '30 days' },

它仍然有空的对象。我在这里做错什么了吗？

auth.module.ts

    @Module({
     imports: [
    UsersModule,

    PassportModule.register({ defaultStrategy: 'jwt' }),
    JwtModule.register({
      secret: 'secret', //to add .env
      secretOrPrivateKey: 'secret',
      signOptions: { expiresIn: '30 days' },
    }),
  ],
  providers: [AuthService, SessionSerializer, JwtService],
  exports: [
    PassportModule.register({ defaultStrategy: 'jwt' }),
    AuthService,
    PassportModule,
    JwtModule,
     ],
    })
     export class AuthModule {}

在auth.services.ts中：

  async loginWithCredentials(user: UserDto) {
    const userEntity: UserDto = await this.validateUser(
      user.username,
      user.password,
    );
    const token = await this.createToken(userEntity);

    return new LoginPayloadDto(token);
  }

  async createToken(user: UserDto): Promise<TokenDto> {
    console.log(user);
    return new TokenDto({
      expiresIn: 30,
      accessToken: await this._jwtTokenService.signAsync(user),
    });
  }

我在应用程序控制器中使用了auth服务：

  @Post('login')
  async loginHttp(@Body() user: UserDto) {
    return this.authService.loginWithCredentials(user);
  }

app.module：

@Module({
  imports: [
    ConfigModule.forRoot({
      load: configs,
      isGlobal: true,
      cache: true,
      envFilePath: ['.env'],
      expandVariables: true,
    }),
    MongooseModule.forRoot(`mongodb://localhost:27017/admin`),
    UsersModule,
    AuthModule,
  ],
  controllers: [AppController],
  providers: [AppService],
  exports: [],
})
export class AppModule {}

ps :即使我把配置放在app模块中，它也不起作用。

我得到的错误：

将JwtService从auth.module提供程序列表中删除，修复了它

        @Module({
     imports: [
    UsersModule,

    PassportModule.register({ defaultStrategy: 'jwt' }),
    JwtModule.register({
      secret: 'secret', //to add .env
      secretOrPrivateKey: 'secret',
      signOptions: { expiresIn: '30 days' },
    }),
  ],
  providers: [AuthService, SessionSerializer],
  exports: [
    PassportModule.register({ defaultStrategy: 'jwt' }),
    AuthService,
    PassportModule,
    JwtModule,
     ],
    })
     export class AuthModule {}
