connect to undefined error: getaddrinfo ENOTFOUND undefined - CNode技术社区

哪个粑粑见过这个问题?node app.js报的 我都不知道该贴什么代码

检查下你的端口是否被占用

@shadow88sky 没有 别的程序用node启动 同一个端口没问题

@CarlosRen 你能换个端口先试试么

@shadow88sky 换了仨都不行~

场景,有没有使用守护进程,以及最基本的贴代码。

if (app.get('env') === 'development') {
 app.use(function(err, req, res, next) {
 res.status(err.status || 500);
 res.render('error', {
 message: err.message,
 error: err
 });
 });
}
// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
 res.status(err.status || 500);
 res.render('error', {
 message: err.message,
 error: {}
 });
});
app.listen(3000);
module.exports = app;

啥都没有,就是照着cnode的源码在改我的dao层

app.get('/save',function(req, res, next){
 var data = "{ DepartmentID : 'emtity_demo_username', DepartmentName : 'emtity_demo_title', DepartmentPosition:'{'develop','operation','manager'}'}";
 Department.newAndSave('emtity_demo_username','emtity_demo_title',"{'develop','operation','manager'}",function(){
	res.send(result);
 });
});

这是save文件吗?

@haozxuan mongoose save数据 我已经找到报错的文件了

错误1:
var Department = require('./model').Department;
应该是掉用proxy的文件
var Department = require('./proxy').Department;
//model文件
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var ObjectId = Schema.ObjectId;
var DepartmentSchema = new Schema({
 DepartmentID : {type : String,default:"default ID"},
 DepartmentName : {type : String, default:"default Name"},
 DepartmentPosition : {type : String, default:"{'p1','p2','p3'}"},
});
mongoose.model("DepartmentModel", DepartmentSchema);
//proxy文件
var EventProxy = require('eventproxy');
var DepartmentModel = require('../model').Deparment;
exports.newAndSave = function (departmentID , departmentName , departmentPosition, callback) {
 var Department = new DepartmentModel();
 DepartmentModel.DepartmentID = departmentID;
 DepartmentModel.DepartmentName = departmentName;
 DepartmentModel.DepartmentPosition = departmentPosition;
 if (departmentID) {
 Department.DepartmentID = departmentID;
 }
 Department.save(function (err) {
 callback(err, Department);
 });
};
我觉得是我抄人家代码抄错了 T T
