Question

我忘记了我问过这个问题， ANSWER 是here

我正在尝试使用AngularJS控制器来显示Nodejs的IP地址，我似乎无法正确获得控制器的$ http部分......我做错了什么？

var requestIp = require('request-ip');
// to convert the ip into geolocation coords
var geoip2 = require('geoip2');
var express = require('express');
var app = express();
var port = process.env.PORT || 8000;

// set view engine
app.set('view engine', 'ejs');

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

geoip2.init(); // init the db

// you can override which attirbute the ip will be set on by
// passing in an options object with an attributeName
app.use(requestIp.mw({ attributeName : 'myCustomAttributeName' }));

// respond to one req
app.get('/', function (req, res, next) {
    // http://sahatyalkabov.com/jsrecipes/#!/backend/get-users-location-from-ip-address
    //res.send('Your IP Address: ' + req.ip);
    //next();
    var ip = req.myCustomAttributeName;// use this for live
    //var ip = '207.97.227.239';/* use this for testing */
    console.log('requestIP is ' + ip);
    //res.end('Hi, your IP address is ' + ip + '\n');
    //res.render('index');
    next();

    // geolocation
    geoip2.lookupSimple(ip, function(error, result) {
      if (error) {
        console.log("Error: %s", error);
      }
      else if (result) {
        console.log(result);
      }
    });

    res.render('index');

});

//custom
app.listen(port, function(){
    console.log('user location app is running');
});

这就是我的Nodejs应用程序。它使用2个Node mods，request-ip和geoip2来请求IP地址，然后为它查找地理定位数据。

这是我的AngularJS代码

angular.module('UserLocation', []);

angular.module('UserLocation')
    .controller('MainController', MainController);

    MainController.$inject = ['$http'];

/*function ctrlFunc () {
    this.message = 'Hello World again';

};*/

    function MainController($http) {
        var vm = this;
        vm.result = {
            city: null
        };

        vm.message = 'Hello World';
        vm.message1 = 'Hello World again';
        // user location
        //function getLocation () {
        vm.getLocation = function() {
            return $http.get('localhost:8000', {
          //return coreService.getLocation(city, {
            params: {city: city}
          })
          .then(function(result){
            var city = result.city;
            return vm.result.city = result.map(function(item) {
              return item.city.result;
            })
          }); 
        };
    };

这是一个地理定位数据的console.log，我试图在浏览器中显示（目前只是城市）

    { country: 'US',
  continent: 'NA',
  postal: '78218',
  city: 'San Antonio',
  location: 
   { accuracy_radius: 1000,
     latitude: 29.4889,
     longitude: -98.3987,
     metro_code: 641,
     time_zone: 'America/Chicago' },
  subdivision: 'TX' }

我在哪里遇到Angular的$ http中的GET请求？如果这是我出错的地方......仍然是Node的新手，所以我不确定......

更新1 这是我通过EJS

提供的HTML文件

    <html ng-app="UserLocation">
<title>The MEAN Stack</title>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.0/angular.js"></script>
</head>
<body ng-controller="MainController as vm">
    {{ vm.message }}
    <br>
    {{ vm.message1 }}
    <br>
    {{ vm.result.city }}
    <script src="/assets/js/app.js"></script>
</body>
</html>

尝试从Nodejs获取IP地址，以使用AngularJS控制器在浏览器中显示
