这里我无法打印我的控制台代码
console.log（“我得到了我请求的数据”）在我的节点服务器中
浏览器控制台中显示的错误如下图所示

下面是server.js的代码
var express = require('express');
var app = express();

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

app.listen(3000);
console.log("server running on port 3000")

下面是controller.js的代码
var app = angular.module('myApp', []);
app.controller('AppCtrl', ['$scope', '$http', function($scope, $http) {
    console.log("Hello World from controller");
    $http({
        method: 'GET',
        url: '/employeelist'
    }).then(function (response) {
            console.log("I got the data I requested");
            $scope.employeelist = response.data;
        });
    employee1 = {
        name: 'Sunil',
        designation: 'Software Developer',
        salary: '20000'
    };
    employee2 = {
        name: 'Vamshi',
        designation: 'Java Developer',
        salary: '30000'
    };

    employee3 = {
        name: 'Chethan',
        designation: 'Dot Net Developer',
        salary: '20000'
    };

    var employeelist = [employee1, employee2, employee3];

    $scope.employeelist = employeelist;
}]);

var app = angular.module('myApp', []);
app.controller('AppCtrl', ['$scope', '$http', function($scope, $http) {
    console.log("Hello World from controller");
    $http({
        method: 'GET',
        url: '/employeelist'
    }).then(function onSuccess(response) {
        console.log("data recieved");
        $scope.employeelist=response.data;
    },function onError(error) {
            console.log("Unknown error");
            $scope.employeelist=error.data;
        });
}]);

我正在尝试在节点服务器中打印控制台代码
我无法在此处打印console.log（“”）

尝试捕捉错误
$http({
    method: 'GET/POST',
    url: 'your/endpoint/url'
})
.then(function onSuccess(response) {
    console.log(response);
})
.catch(function onError(error) {
    console.log(error);         
});

如果要全局抑制警告
app.config(['$qProvider', function ($qProvider) {
    $qProvider.errorOnUnhandledRejections(false);
}]);

但总是建议捕获错误，而不是抑制警告尝试捕获错误
$http({
    method: 'GET/POST',
    url: 'your/endpoint/url'
})
.then(function onSuccess(response) {
    console.log(response);
})
.catch(function onError(error) {
    console.log(error);         
});

如果要全局抑制警告
app.config(['$qProvider', function ($qProvider) {
    $qProvider.errorOnUnhandledRejections(false);
}]);

但是总是建议捕获错误，而不是抑制警告我已经更改了server.js和controller.js代码，现在如果打开localhost，我可以接收get请求
以下是我所做的更改
server.js
var express = require('express');
var app = express();

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

app.listen(3000);
console.log("server running on port 3000")

var express = require('express');
var app = express();

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

app.get("/employeelist", function (req,res) {
    console.log("I received a GET Request")

    employee1 = {
        name: 'Sunil',
        designation: 'Software Developer',
        salary: '20000'
    };

    employee2 = {
        name: 'Vamshi',
        designation: 'Java Developer',
        salary: '30000'
    };

    employee3 = {
        name: 'Chethan',
        designation: 'Dot Net Developer',
        salary: '20000'
    };

    var employeelist = [employee1, employee2, employee3];
    res.json(employeelist);
});

app.listen(3000);
console.log("server running on port 3000");

controller.js
var app = angular.module('myApp', []);
app.controller('AppCtrl', ['$scope', '$http', function($scope, $http) {
    console.log("Hello World from controller");
    $http({
        method: 'GET',
