我已经创建了一个OData服务，但是当BreezeJS错误查询时。 以下是我的查询结果
http://115.78.161.4:96/odata/ShArticles
Breeze Config： breeze.config.initializeAdapterInstance（＆＃39; dataService＆＃39;，＆＃39; webApiOData＆＃39;，true）;
(function () {
'use strict';
var serviceId = 'entityManagerFactoryOData';
angular.module('myApp').factory(serviceId, ['breeze', emFactory]);
function emFactory(breeze) {
configureBreeze();
var serviceRoot = window.location.protocol + '//' + '115.78.161.4:96'+ '/';
var serviceName = serviceRoot + 'odata/';
var factory = {
newManager: newManager,
serviceName: serviceName
};
return factory;
function configureBreeze() {
breeze.config.initializeAdapterInstance('dataService', 'webApiOData', true);
//dùng web API Odata để query và save
//breeze.NamingConvention.camelCase.setAsDefault();//chuyển đổi giữa server-side PascalCase và client-side camelCase
}
//Tạo new instance(s) của BreezeJS EntityManager để dùng trong một 'datacontext' service
function newManager() {
var mgr = new breeze.EntityManager(serviceName);
return mgr;
}
}
})();

function getShArticles(forceRefresh) {
var count;
if (forceRefresh) {
if (manager.hasChanges()) {
count = getChangesCount();
manager.rejectChanges();//trả về giá trị ban đầu trong cache cho các giá trị bị thay đổi nhưng không được lưu
logWarning('Có ' + count + ' bị thay đổi', null, true);
}
}
//Nếu không forceRefresh,cân nhắc nhận từ cache hơn là truy vấn giá trị mới từ xa
return breeze.EntityQuery.from('ShArticles')
.using(manager).execute()
.then(success).catch(failed);
function success(response) {
count = response.results.length;
logSuccess('Nhận ' + count + ' dòng', response, true);
return response.results;
}
function failed(error) {
var message = error.message || "Truy vấn bảng ShArticles lỗi";
logError(message, error, true);
}
}

public class ShArticlesController: ODataController

真诚地感谢您对任何帮助的评论
代码注册EdmBuilder：
public static void Register(HttpConfiguration config)
{
config.MapHttpAttributeRoutes();
config.Routes.MapODataRoute(
routeName: "odata",
routePrefix: "odata",
model: EdmBuilder.GetEdm<vl360Context>(),
batchHandler: new DefaultODataBatchHandler(GlobalConfiguration.DefaultServer)
);
config.Routes.MapHttpRoute(
name: "DefaultApi",
routeTemplate: "api/{controller}/{id}",
defaults: new { id = RouteParameter.Optional }
);
// Uncomment the following line of code to enable query support for actions with an IQueryable or IQueryable<T> return type.
// To avoid processing unexpected or malicious queries, use the validation settings on QueryableAttribute to validate incoming queries.

config.EnableQuerySupport();
