How to get response of serverResponse in NestJS-CodePudding

When i create Logger middleware with Nestjs I want logger response || data of server send for client but in Response from express but it not found option

import { NextFunction, Request, Response } from 'express';
@Injectable()
export class EcomWebLogerMiddleware implements NestMiddleware {
 private logger = new Logger();
 use(request: Request, response: Response, next: NextFunction): void {
  const { method, url: path, query, params, body } = request;
  this.logger.log(
  ` ${method} ${path} query: ${JSON.stringify(
    query
  )} params: ${JSON.stringify(params)} body: ${JSON.stringify(body)}`,
  'FE Request'
 );
 response.on('close', () => {
  const { statusCode } = response;
  // i want get data in response:Response from express
  this.logger.log(`${method} ${statusCode} ${path}  `, 'FE Response');
  });
 next();
 }
}

With ExceptionFilter you can use ArgumentsHost after you can use it to getResponse

@Catch(HttpException)
export class HttpExceptionFilter implements ExceptionFilter {
 constructor(private readonly responseUtils: ResponseUtils) {}
 catch(exception: HttpException, host: ArgumentsHost) {
 const ctx = host.switchToHttp();
 const res = ctx.getResponse<Response>();
 const status = exception.getStatus();
 const response: any = exception.getResponse();
 // this is response i want get
... }

CodePudding user response：

It would be better to implement with an interceptor. It is very similar to koa's middleware.

CodePudding user response：

can you show your package.json, try install "@types/express" dependency
