我使用 jaydata.js 调用了 odata 网络服务，但它返回 401 Unauthorized。

即使浏览到服务并首先在第二个浏览器选项卡中手动进行身份验证，仍然会在第一个选项卡中获得 401。

这是我的代码：

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <script src="Scripts/datajs-1.0.3.js" type="text/javascript"></script>
    <script src="Scripts/jquery-1.8.3.js" type="text/javascript"></script>
    <script src="Scripts/jaydata.js" type="text/javascript"></script>
    <script src="Scripts/DynamicsNav70.js" type="text/javascript"></script>
    <script src="Scripts/jaydataproviders/oDataProvider.js" type="text/javascript"></script>
    <script>
        nav = new NAV.NAV({
            name: 'oData', oDataServiceHost: 'http://XXX.cloudapp.net:7048/DynamicsNav70/OData',
            user: "XXX",
            password: "XXX"
        });

        $(document).ready(function () {
            nav.Customers.forEach(function (customer) {
                var item = "<li ><a href=#>@name</a></li>".replace("@name", customer.Name);
                $('#customers').append(item);
            });
        });

    </script>
    <title></title>
</head>
<body>
    <h1>Customers</h1>
    <ul id="customers"></ul>
</body>
</html>

这是来自浏览器的信息：

我在这件事上完全是菜鸟，所以任何关于解决方案或更好地理解问题的建议都可能会有所帮助
