android 2.3.3上带有授权头和CORS的Ajax GET请求

我正试图在android 2.3.3上发出一个跨域GET请求。我正在服务器上使用CORS筛选器。我已经在chrome、firefox、iphone上测试过了，效果很好。在android 2.3.3中，飞行前的请求看起来不错，但实际的请求并没有发送原始标头。我很好地恢复了数据，但是ajax出错，状态为0。我试着把它改成一个帖子请求，结果成功了

以下是ajax代码：

以下是get的结果（不起作用）

以下是发送帖子的结果（有效）

我做了更多的测试，从等式中去掉了授权头，它与GET一起工作。不确定授权标头为什么会导致get请求失败。有什么想法吗？

我也有同样的问题，但这不是授权标头的问题，而是GET请求中缺少的原始标头的问题。这也是post请求起作用的原因——存在一个Origin头，并且Origin头对于CORS是必需的

---

重要的是选项飞行前调用有一个Origin头集。

我创建了一个简单的测试页面来测试CORS请求。你能在安卓系统中尝试一下你的请求，看看响应是什么吗：谢谢你的响应！正在向发送GET请求？id=6058740&httpstatus=200&methods=GET&headers=Authorization，启动自定义头XHR事件：loadstart启动XHR事件：readystatechange启动XHR事件：错误XHR状态：0 XHR状态文本：我得到了android 2.2、2.3和3.x的相同响应。值得一提的是，控制台日志会在3.x:E/browser（333）中返回此消息：console:XMLHttpRequest无法加载。访问控制不允许原点-允许原点。null:1该图表表明CORS支持应该在这些Android版本上工作：尽管这可能是一个边缘案例错误。我使用的是安卓4.0.3，它可以正常工作。也许你现在可以继续使用POST？谢谢你的关注。是的，使用post是我最终可能使用的解决方法。

$.ajax( {
    beforeSend: function (xhr, settings) {
        xhr.withCredentials = true;
        xhr.setRequestHeader('Authorization', 'Bearer myoathtoken');
    },
    dataType: "json",
    type: "GET",
    url: getMyUrl() + '/data.json',
    success: function(data) {
        alert("It works");
    }
});
