我正在尝试将Mongo DB中的一些数据显示在前端。我正在使用MEAN堆栈,我相对较新。
我已经成功地将数据以JSON格式显示在localhost URL(localhost:3030 / incidents)中,但是无法将干净数据显示在前端(位于localhost:9000)。
这是我的代码到目前为止服务器端( router.js )的样子:
"use strict";
var config = require('../config/database-config');
var Router = function (options) {
var self = this;
self.environment = options.environment;
self.route = function(app) {
var IncidentController = require('./controllers/incident-controller.js');
var IncidentModel = require('./models/incident-model.js');
var incidentModel = new IncidentModel(config[`${self.environment}`]);
console.log("Incident Model", incidentModel);
var incidentController = new IncidentController({model: incidentModel});
app.get('/api/incident/:id', incidentController.findIncidentById);
app.get('/incidents', incidentController.getAllIncidents);
};
return self;
};
module.exports = Router;
客户端:
services.js:
'use strict';
angular.module('victimList.services', []).factory('Victim', function($resource) {
return $resource('http://localhost:3030/api/incident/:id');
});
data.js:
'use strict';
angular.module('victimList', [])
.service('victimList')
.controller('DataCtrl', ['victimService', function ($scope, victimService) {
victimService.getVictims(function(victims) {
$scope.victims = victims;
});
}])
.factory('victimSerivce', function($http) {
var getVictims = function(callback) {
$http.get('http://localhost:3030/incidents').success(function(data){
callback(data);
});
};
return {
getVictims: getVictims
};
});
app.js:
'use strict';
angular
.module('frontendApp', [
'ngAnimate',
'ngCookies',
'ngResource',
'ngRoute',
'ngSanitize',
'ngTouch',
'victimList',
])
.config(function ($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'views/main.html',
controller: 'MainCtrl',
controllerAs: 'main'
})
.when('/victims', {
templateUrl: 'views/victims.html',
controller: 'DataCtrl',
controllerAs: 'victims'
})
.otherwise({
redirectTo: '/'
});
});
victims.html:
<div ng-app="victimList">
<h1>Testing</h1>
<div ng-controller="DataCtrl">
<ul ng-repeat="victim in victims">
<li>1</li>
<li>{{ victim.firstname }} {{ victim.lastname }}</li>
</ul>
</div>
当我导航到localhost:9000 / victim页面时,我得到了标头标签,但没有数据。控制台显示此错误:
Error: [$injector:unpr] Unknown provider: victimServiceProvider <- victimService <- DataCtrl
我能错过什么?在此先感谢您的帮助!
答案 0 :(得分:0)
我明白了!我需要添加以下内容:
angular.module('victimList', [])
.service('victimService')
.controller('DataCtrl', ['$scope', 'victimService', function ($scope, victimService) {
victimService.getVictims(function(victims) {
$scope.victims = victims;
});
}])
^^请注意&#39; $ scope&#39;在第3行添加。
