如何从 NestJS 的模块导入中获取配置? [英] How to get the configurations from within a module import in NestJS?

问题描述

假设我的模块定义如下:

Let's say I have my module defined as below:

@Module({
  imports: [
    PassportModule.register({ defaultStrategy: 'jwt' }),
    JwtModule.register({
      // Use ConfigService here
      secretOrPrivateKey: 'secretKey',
      signOptions: {
        expiresIn: 3600,
      },
    }),
    PrismaModule,
  ],
  providers: [AuthResolver, AuthService, JwtStrategy],
})
export class AuthModule {}

现在如何从这里的 ConfigService 获取 secretKey ?

Now how can I get the secretKey from the ConfigService in here?

推荐答案

你必须使用 registerAsync，这样你才能注入你的 ConfigService.有了它，您可以导入模块、注入提供程序，然后在返回配置对象的工厂函数中使用这些提供程序:

You have to use registerAsync, so you can inject your ConfigService. With it, you can import modules, inject providers and then use those providers in a factory function that returns the configuration object:

JwtModule.registerAsync({
  imports: [ConfigModule],
  useFactory: async (configService: ConfigService) => ({
    secretOrPrivateKey: configService.getString('SECRET_KEY'),
    signOptions: {
        expiresIn: 3600,
    },
  }),
  inject: [ConfigService],
}),
