我现在正在使用 meanstack 我尝试在 angularjs 的帮助下从 mongodb 获取数据我在这项技术中非常新。我现在正确插入值我想从 mongodb-mongoose 检索

var app = angular.module("App", [ ]);

  
app.controller('MongooseController', ['$scope', '$http' ,'$window', '$filter',
 
 
function ($scope, $http, $window, $filter) {
      

    debugger;
    
    var refresh = function () {
        $http.get('/ViewUser').then(function (response) {
            $scope.ViewUsers = response.data;
        });
 
    };
    refresh();

    $scope.AddNewDetails = function ( ) {

        $http.post('/AddNewDetails', $scope.user).then(function (response) {
            

        });
    };
 

}]);









server
var express = require('express');
var app = express();
var mongoose = require('mongoose');
var Schema = mongoose.Schema();
var bodyParser = require('body-parser');

 


app.use(express.static(__dirname + "/public"));

app.use(bodyParser.json());
mongoose.connect('mongodb://localhost/crud');

var Schema = new mongoose.Schema({
    email: String,
    name: String,
    age: Number,
 

    date: { type: Date, default: Date.now }
   

});

var user = mongoose.model('emps', Schema);

app.get('/ViewUser', function (req, res) {

    user.find({}, function (err, docs) {
        console.log(docs);
    });

});
 
app.post('/AddNewDetails', function (req, res) {

 
    new user({
        email: req.body.email,
        name: req.body.name,
        age: req.body.age
       


    }).save(function (err, doc) {

        if (err) {
            res.json(err);
        }
        else {
             
            res.send('Successfully inserted!');
        }
    });
});





app.listen(8082);
console.log("server running on port 8082");

【解决方案1】：

应该是，

User.find({}, function(err, docs) {
 console.log(docs);
}

还将您的请求更改为，

 $http.get('/ViewUser').then(function (response) {
            $scope.ViewUsers = response.data;
 });
