在示例 ToDo 项目之后，我正在使用 Angular 和 Breeze 测试示例 CRUD。但由于某种原因，我收到错误无法调用未定义的方法“getAll”。（我的 odata 托管在另一个 localhost 服务器上，并且启用了 CORS，我已经对其进行了测试）

这是我的代码：

主.js：

var app = {};

app.adminMuscleGroup = angular.module('WebApp', []);

数据服务：

app.adminMuscleGroup.dataService = (function (breeze, logger) {

    breeze.config.initializeAdapterInstances({ dataService: "OData" });

    var servicename = 'http://localhost:23758/odata/';

    var manager = new breeze.EntityManager(servicename);

    manager.enableSaveQueuing(true);

    var dataService = {
        getAll: getAll,

    };

    return dataService;

    function getAll() {
        var query = breeze.EntityQuery.from("MuscleGroup").orderBy("Name");

        return manager.executeQuery(query);
    }



})(breeze, app.logger);

控制器：

app.adminMuscleGroup.controller('AdminMuscleGroupCtrl', function($scope) {
    var dataService = window.app.dataService;
    var logger = window.app.logger;

    $scope.items = [];

    $scope.getAllMuscleGroups = function () {
        dataService.getAll()
            .then(querySucceeded)
            .fail(queryFailed);
    };

    $scope.getAllMuscleGroups();

    function querySucceeded(data) {
        $scope.items = [];
        data.results.forEach(function (item) {
            $scope.items.push(item);
        });

        $scope.apply();

        logger.info("Fetched all Muscle Groups");
    }

    function queryFailed(error) {
        logger.error(error.message, "Query failed");
    }

}

这是整个错误：

尝试将dataService直接注入控制器

app.adminMuscleGroup.controller('AdminMuscleGroupCtrl', function($scope, dataService) {
    var dataService = window.app.dataService; // -> delete this

这是愚蠢的错误，我改变了这一行：

var dataService = window.app.dataService;

进入这个：

var dataService = window.app.adminMuscleGroup.dataService;

现在它可以工作了
