我这里有一些有角度的js代码

        <body>    
      <div ng-app="">

var mysql = require('mysql');

var connection = mysql.createConnection({
  host: 'localhost',
  user: '',
  password: '',
  database: 'copedb'
});
connection.connect();
var cope = {
  author: 'XYZXYZ',
  title: 'Testing Node',
  body: 'Node JS'
};
var query = connection.query('insert into cope set ?', cope, function(err, result) {
  if (err) {
    console.error(err);
    return;
  }
  console.error(result);
});

首先，根据您的需要，使用npm模块Express/Restify创建一个RESTful服务，这将反过来与您的SQL数据库通信

一旦服务在服务器级别启动并运行，您现在就可以在客户端级别向服务器发送/接收数据了

注意：使用AngularJS的$resource而不是$http服务与服务器对话

$resource

它可以作为您入门的踏脚石：

Index.html server.js-Nodejs

无论如何，我已经在这里编写了实际的工作代码

index.html

 <!DOCTYPE html>
 <html lang="en">
 <head>
 <script src="angular.min.js"></script>
 <script src="app.js"></script>
 </head>
 <body ng-app="myApp">
 <div ng-controller="myCtrl">
 <form>
    Author:
    <input type="text" ng-model="data.author">
    <br>
    <br> Title:
    <input type="text" ng-model="data.title">
    <br>
    <br> Body:
    <input type="author" ng-model="data.body">
    <br>
    <br>
    <input type="submit" value="Submit" ng-click="submit()">
  </form>
  </div>
  </body>
  </html>

server.js

 var app = angular.module('myApp', []);
 app.controller('myCtrl', function($scope,$http) {
 $scope.data = {};
$scope.submit= function(){
    console.log('clicked submit');
    $http({
        url: 'http://localhost:8080/blah',
        method: 'POST',
        data: $scope.data
    }).then(function (httpResponse) {
        console.log('response:', httpResponse);
    })
   }
 });

   var express = require('express');
   var bodyParser = require('body-parser');
   var mysql = require('mysql');
   var app = express();

    app.use(bodyParser.json({limit: '50mb'}));
    app.use(express.static('public'));

  var connection = mysql.createConnection({
  host: 'localhost',
  user: 'root',
  password: '',
  database: 'copedb'
   });
   connection.connect();

    app.post('/blah', function(req, res, next) {
    var cope = req.body;
    console.log('request received:', req.body);
   var query = connection.query('insert into cope set ?', cope, function (err,     result) {
    if (err) {
        console.error(err);
        return res.send(err);
    } else {
        return res.send('Ok');
    }
    });
    //res.send('received the data.');
    });
    app.listen(8080);

关于如何将数据从AngularJS前端传递到Nodejs后端的最简单答案

带有html的AngularJs代码

 <body>
 <script src="http://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
    <div ng-app="app" ng-controller="myCtrl">
        <p>First Name: <input type="text" name="firstName" ng-model="firstName" required /></p>
        <p>Lirst Name: <input type="text" name="lastName" ng-model="lastName" required /></p>
        <button ng-click="SendData()">Submit</button>
        <hr />
        {{ PostDataResponse }}
    </div>
    <script>
        var app = angular.module("app",[]);
        app.controller("myCtrl", function($scope,$http){
        $scope.SendData = function() {
            var data = {
                    fName : $scope.firstName,lName : $scope.lastName
                }
            $http.post('/postFormAngular', data)
                .success(function (data, status, headers, config) {
                    $scope.PostDataResponse = data;
                })
                .error(function(data, status, header, config){
                    $scope.PostDataResponse = "Data: " + status;


                });
        };  
        });
    </script>
 </body>

我应该能够从angular js向mysqlcheck$http服务发送数据，谢谢。我在sever.js上画了红色下划线。我是否将server.js文件放在了特定的位置？我正在将webstorm与nodejs express项目一起使用。server.js是您的程序的入口文件。我不知道Webstorm.mysql下划线-module not listed package.jsonfixed-ALT+Enter-add dependency。这是一段基本代码。我甚至没有测试它。从中学习是件好事。从这个免费课程学习angularjs。

 var app = angular.module('myApp', []);
 app.controller('myCtrl', function($scope,$http) {
 $scope.data = {};
$scope.submit= function(){
