Question

我正在尝试从角度js进行服务调用。我下载了angular seed project。在view1.js内写了以下代码来调用服务：

'use strict';

angular.module('myApp.view1', ['ngRoute','ngResource'])

.config(['$routeProvider', function($routeProvider) {
  $routeProvider.when('/view1', {
    templateUrl: 'view1/view1.html',
    controller: 'View1Ctrl'
  });
}])
.factory('Entry', ['$resource',function($resource) {
  return $resource('http://localhost:8000/emp/'); // Note the full endpoint address
}])
.controller('View1Ctrl', ['Entry',function(Entry) {
  var entries = Entry.query(function() {
    console.log(entries);
  });
}]);

以下是我已包含所需脚本的index.html：

    <!DOCTYPE html>

  <script src="components/version/version-directive.js"></script>
  <script src="components/version/interpolate-filter.js"></script>
</body>
</html>

但是在运行应用程序时，它会在浏览器控制台中显示以下错误：

    Uncaught Error: [$injector:modulerr] Failed to instantiate module myApp due to:
Error: [$injector:modulerr] Failed to instantiate module myApp.view1 due to:
Error: [$injector:modulerr] Failed to instantiate module ngResource due to:
Error: [$injector:nomod] Module 'ngResource' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument.

Answer 1

<script src="angular-resource.js"></script>

应该是：

<script src="bower_components/angular-resource/angular-resource.js"></script>

Answer 2

唯一有意义的是angular-resource.js文件未正确加载，您是否可以查看网络选项卡并查看实际加载的文件以及模块的名称是什么？确保你输入正确。

（很抱歉没有评论，还没有足够的代表）。

Answer 3

你缺少依赖列表。

如果您要将一个数组作为依赖项传递以进行注入，则需要告诉angular。

['Entry', function (Entry) { }];应该做到这一点，或者只做function (Entry) { }。

Entry未定义的原因是因为angular不知道你需要注入什么（你将数组符号传递给angular的DI系统）

ps：sry for bad english

AngularJS错误：模块＆＃39; ngResource＆＃39;不可用！您要么错误拼写了模块名称，要么忘记加载它
