'NestMiddleware<any, any>' 不能分配给'Function |键入<任何>'

Question

我将一个中间件注入到一个模块中。

我在调用consumer.apply(middleware) 时遇到类型错误：

代码：

@Module({
  ...
})
export class FooModule implements NestModule {

  @Inject(FOO_MIDDLEWARE)
  private middleware: NestMiddleware;

  public configure(consumer: MiddlewareConsumer) {
    consumer
      .apply(this.middleware)
      .forRoutes('foo');
  }
}

错误：

TS2345: Argument of type 'NestMiddleware<any, any>' is not assignable to parameter of type 'Function | Type<any>'.   Type 'NestMiddleware<any, any>' is missing the following properties from type 'Type<any>': apply, call, bind, prototype, and 5 more.

Answer 1

我找到了解决方法。我做到了：

• private middleware: Type<any>

代替：

• private middleware: NestMiddleware

正在从@nestjs/common 导入Type。
