javascript – 在Internet Explorer 9中更改域名后,Ajax停止工作

我们正在开发一个使用 html5,jQuery(1.8.2)和jQuery mobile的移动网站,同时进行jQuery ajax调用(get和post).
在我们更改了域名后,我们对ie9的ajax调用进行“访问被拒绝”.
我们试图包含 jquery.ieco​​rs.js.但我们仍然得到同样的错误.这有什么解决方案吗？

示例代码：

$.support.cors = true;

$.ajax({
    cache: false,async: true,crossDomain: true,timeout: 600000,url: baseUrl + '/SmartTouch/restServices/PrefferedHotels',type: 'GET',beforeSend: function (xhr) {
        xhr.setRequestHeader("Authorization","Basic " + myencoded);
    },contentType: "application/x-www.form-urlencoded; (http://www.form-urlencoded;) (http://www.form-urlencoded;) charset=UTF-8",success: function (data) {

        alert("success");
    },error: function (jqXHR,textStatus,errorThrown) {


        alert("error!!::" + JSON.stringify(jqXHR));

        alert('response: ' + jqXHR.responseText);
        alert('code: ' + jqXHR.getResponseHeader('X-Subscriber-Status'));
        alert("textStatus " + textStatus);
        alert("errorThrown " + errorThrown);

    }
});

编辑：

beforeSend: function (xhr) {
    xhr.setRequestHeader("Authorization","Basic " + myencoded);
    xhr.setRequestHeader("Access-Control-Allow-Origin","*");
    xhr.setRequestHeader("Access-Control-Allow-Methods","POST,GET,OPTIONS");
},success: function (data) {
    alert("success");
},errorThrown) {
    alert("error!!::" + JSON.stringify(jqXHR));

IE9中的请求和响应标头：

    Key Value
    Request GET url HTTP/1.1
    Accept  text/html,application/xhtml+xml,*/*
    Accept-Language en-US
    User-Agent  Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)
    Accept-Encoding gzip,deflate

解决方法

这种Content-Type看起来很奇怪：

application/x-www.form-urlencoded; (http://www.form-urlencoded;) (http://www.form-urlencoded;) charset=UTF-8"

我可以想象IE有问题.

尝试正确的一个：

application/x-www-form-urlencoded; charset=UTF-8
                 ^-- notice: no dot!

IE也可能存在授权问题.
也许myencoded不在范围内或未正确填写.调试此变量并查看此问题：Authorization through setRequestHeader
