Node.js Express.js : Getting the body of a sent response

Question

我的代码示例如下:

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);     
}

我想检索 msg使用 res.send(msg); 发送

Express.js's res中有选项吗反对在发送响应后这样做？

Answer 1

您可以使用request对象来获取它

这样做:

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);     
}
