Firefox不会在飞行前发送跨源资源共享?

标签: ajax firefox xmlhttprequest cors

我已经实现了一个利用CORS从另一台服务器收集JSON数据的Web应用程序。服务器在不同的子域上运行。所有似乎都正确实现,并且它与Chromium一起使用。以下是我的请求副本,来自Chromium。

我的问题是在Firefox(使用13.0.1测试过)中,我的AJAX资源没有请求。不会发送预检请求,也不会发出实际请求。相反,我从XMLHttpRequest.send()函数中得到了这个错误:

[21:40:27.546] uncaught exception: [Exception... "Access to restricted URI denied"  code: "1012" nsresult: "0x805303f4 (NS_ERROR_DOM_BAD_URI)"  location: "http://192.168.1.99:2502/static/mootools-core-1.4.5.js Line: 5398"]

我正在使用Mootools的Request.JSON对象,它设置了各种额外的标题,这意味着确实需要预检。但是,它永远不会发送。

不幸的是,JSONP不是一个选项,因为数据很敏感。

有没有人能够深入了解问题所在? 非常感谢。


工作示例,来自Chromium:

答案在问题的评论中给出。由于我提供的HTTP身份验证用户名,Firefox没有发送请求。
