Question

我有一个来自yeoman发电机的angular.js安装。对于express.js，我的印象是当node.js服务器启动时（使用grunt serve），使用/读取app.js文件来运行函数。但是，在我的app / scripts / app.js中我的函数rest.runApi（）;没有运行。为什么是这样？如何使该功能在app.js中运行？服务器启动时输出没有错误：

一个@ demo~ / node_stuff $ cat app / scripts / app.js

'use strict';

var rest = require('./memory.js');

rest.runApi();

var myappApp = angular
  .module('myappApp', [
    'ngCookies', 'duScroll', 'ngRoute'
  ]).config(function($routeProvider) {
      $routeProvider.when('/home', {
      templateUrl: 'views/home.html',
      controller: 'HomeController'
      });

      $routeProvider.when('/first', {
      templateUrl: 'views/first.html',
      controller: 'FirstController'
      });



      $routeProvider.otherwise({ redirectTo: '/home'});
  });

myappApp.controller('Scroller', function($scope, $location, $document, $anchorScroll) {
    $scope.scrollTo = function(id) {
    var el = angular.element(document.getElementById(id));
    $document.scrollTo(el, 2000);
    }
});

myappApp.controller('HomeController', function($scope, $location, $anchorScroll) {
    $scope.scrollTo = function(id) {
    $location.hash(id);
    $anchorScroll();
    }
});

myappApp.controller('FirstController', function($scope, $location, $anchorScroll) {
    $scope.scrollTo = function(id) {
    $location.hash(id);
    $anchorScroll();
    }
});

一个@ demo~ / node_stuff $ cat app / scripts / memory.js

var rest = require('restler');

CHECK='chMNWXNki7';
URL='https://monitoring.api.rackspacecloud.com/v1.0/1324/';
SLUG='entities/enij5mKIvs/checks/';
MODE='/test';

url = CHECK+URL+SLUG+CHECK+MODE
headers = { headers: 
    { "X-Auth-Token": "377c" }
}

function runApi() {
    rest.post(url, headers).on('complete', function(data, response) {
            console.log(JSON.stringify(data, "\n", 2));
            console.log("--------------------------------------------------------");
            console.log(response.statusCode);
        });
}

module.exports.runApi = runApi;

当Angular应用程序执行引导时，它只在其框架内运行代码。为了在加载/引导过程的最开始时运行它，您可以将它放在应用程序的run方法中。

myappApp.run(function apprun() {
  var rest = require('./memory.js');
  rest.runApi();
});

您可以做到这一点的其他地方是在工厂内。由于工厂是Angular的单身人士，它也将在引导期间运行。不同之处在于工厂初始化的顺序是不确定的，但是如果你想保持执行结果以后再使用，那就好了。

myApp.factory('RestRunFactory', function factoryrun() {
  var rest = require('./memory.js');
  rest.runApi();
});
