Javascript不会从django做跨域请求

嗨,这是一个奇怪的问题。我试图用django提供下面的index.htm文件。单击该按钮时,页面(而不是服务器)会执行跨域请求。如果我直接在浏览器中加载索引文件就可以了。但是,如果我使用django服务它,我会在同一个浏览器(Safari)中收到“尝试加载资源时出错”。我正在使用(YQL)此方法进行跨域请求:http://james.padolsey.com/javascript/cross-domain-requests-with-jquery/

{
    $.ajax({
        url: 'http://www.google.com',
        type: 'GET',
        success: function(res) {
        var headline = $(res.responseText).text();
            document.getElementById("demo").innerHTML=res;
        },
    beforeSend : function(xhr, settings) {
        xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        xhr.setRequestHeader("Cache-Control", "no-cache");
        if (!csrfSafeMethod(settings.type)) {
            xhr.setRequestHeader("X-CSRFToken", getCookie("csrftoken"));
        }
    }
    });
}
function csrfSafeMethod(method) {
    // these HTTP methods do not require CSRF protection
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}

<button onclick="myFunction()">Click me</button>

<p id="demo"></p>

在ajax函数中添加以下代码:

    beforeSend : function(xhr, settings) {
        xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
        xhr.setRequestHeader("Cache-Control", "no-cache");
        if (!csrfSafeMethod(settings.type)) {
            xhr.setRequestHeader("X-CSRFToken", getCookie("csrftoken"));
        }
    },

此脚本中的此功能:

function csrfSafeMethod(method) {
    // these HTTP methods do not require CSRF protection
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}
