无法在"xmlhttprequest"上执行“发送"，无法加载 [英] Failed to execute 'send' on 'xmlhttprequest' failed to load

问题描述

大家好，当我尝试运行在DevExtreme中创建的应用程序时，出现标题中提到的错误.

Hello guys I'm getting the error mentioned in the headline when i try to a run my app created in DevExtreme.

每当Í在DevExtreme模拟器中运行我的应用程序时，它便会正常运行，但是当我尝试在手机上运行该应用程序时，我会遇到上述错误.

Whenever Í run my app in the DevExtreme simulator it works as it should but when I try to run the app on my phone I get the mentioned error.

    function CallService() {
    var baseAddress = "http://192.168.80.2:8080/WebService/rest/WarehouseServices/";

    $.ajax({
        type: "GET",
        url: baseAddress + 'getPickingOrders',
        contentType: 'applicaiton/xml; charset=utf-8',
        dataType: "xml",
        async: false,
        success: function (xmlObject) {
            xml = xmlObject;
            console.log("succes ramt");
            alert(xml);
            console.log(xml);
            dataSource = GetData(xmlObject);
        },
        error: ErrorOccur
    });

}

很长一段时间以来，我一直在努力解决这个问题，但我没有主意.

I have been strugling with this problem for a long time now and I'm out of ideas.

推荐答案

如果运行此脚本的页面不在 http://192.168.80.2:8080 上，而您的服务器不在启用跨源资源共享的源头，您就遇到了相同起源政策，该政策禁止跨域ajax.

If the page where this script is running isn't on http://192.168.80.2:8080 and your server doesn't enable Cross-Origin Resource Sharing for whatever origin it's on, you're running into the Same Origin Policy, which prohibits cross-origin ajax.
