Node.js Express.js：获取已发送响应的正文

Question

A sample of my code will be:

middlewareA(req,res,next){
  res.send('some msg to client');
  next()
}
middlewareB(req,res,next){
  var sent_msg_body = res.<some method\property to get body>
  logger.info(sent_msg_body);     
}

I woukd like to retrieve the msg that was sent using res.send(msg);

Is there an option in Express.js's res object to do that after the response was already sent?

Answer 1

You can use request object to get it

Do like this:

middlewareA(req,res,next){
  res.send('some msg to client');
  req.message='some msg to client';
  next();
}
middlewareB(req,res,next){
  var sent_msg_body = req.message
  logger.info(sent_msg_body);     
}
