在nestjs中的另一个拦截器中使用拦截器

// interceptorA.ts
import { Injectable, NestInterceptor, ExecutionContext, CallHandler } from '@nestjs/common';

@Injectable()
export class InterceptorA implements NestInterceptor {
  intercept(context: ExecutionContext, next: CallHandler): Observable<any> {
    console.log('Interceptor A before...');
    const request = context.switchToHttp().getRequest();
    // 执行一些操作
    return next.handle().pipe(
      tap(() => console.log('Interceptor A after...')),
    );
  }
}

// interceptorB.ts
import { Injectable, NestInterceptor, ExecutionContext, CallHandler } from '@nestjs/common';

@Injectable()
export class InterceptorB implements NestInterceptor {
  intercept(context: ExecutionContext, next: CallHandler): Observable<any> {
    console.log('Interceptor B before...');
    const request = context.switchToHttp().getRequest();
    // 执行一些操作
    return next.handle().pipe(
      tap(() => console.log('Interceptor B after...')),
    );
  }
}

import { Controller, Get, UseInterceptors } from '@nestjs/common';
import { InterceptorA } from './interceptorA';
import { InterceptorB } from './interceptorB';

@Controller('example')
@UseInterceptors(InterceptorA, InterceptorB)
export class ExampleController {
  @Get()
  getData() {
    return 'Hello World!';
  }
}
