获取nodejs中另一个控制器中的一个控制器的响应

我面临一个问题，以获得来自另一个控制器内的一个控制器的响应。

如何从getUserAppointmentDetails.js获取responseAppointment.js文件的响应

getUserAppointmentDetails.js const con = require('./../database_connection'); exports.getUserAppointmentDetails = function (req, res, next) { // const details = req.body; con.query('SELECT * from user_appointment_details WHERE id = 1', (err, respond) => { if (err) throw err; res.send({result: respond}); }); } Another file respondAppointment.js const con = require('./../database_connection'); const userDetails = require('./getUserAppointmentDetails'); exports.respondAppointment = function (req, res, next) { const details = req.body; con.query('update user_appointment_details SET status = "' + details.status + '" WHERE id = ' + details.id, (err, respond) => { if (err) throw err; res.send({result: respond}); }); var userData = userDetails.getUserAppointmentDetails(req, res, next); } 

如果有人有任何想法请回应。

这里的问题是，你在发送响应，而不是实际返回从另一个函数callback的结果。

假设您想要getUserAppointmentDetails.js中的respondAppointment.js结果。 在getUserAppointmentDetails.js和getUserAppointmentDetails.js进行更改以将该值返回给调用函数。

getUserAppointmentDetails.js

  const con = require('./../database_connection'); exports.getUserAppointmentDetails = function (idToGet) { // const details = req.body; con.query('SELECT * from user_appointment_details WHERE id = '+idToGet, (err, respond) => { if (err) throw err; return respond; }); } 

另一个文件：respondAppointment.js

 const con = require('./../database_connection'); const userDetails = require('./getUserAppointmentDetails'); exports.respondAppointment = function (req, res, next) { const details = req.body; var userData = userDetails.getUserAppointmentDetails(details.id); console.log(userData); con.query('update user_appointment_details SET status = "' + details.status + '" WHERE id = ' + details.id, (err, respond) => { if (err) throw err; res.send({result: respond}); }); }
