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。一切似乎都正确实施,并且与 Chromium 配合得很好。以下是我的请求副本,来自 Chromium。
我的问题是在 Firefox(用 13.0.1 测试)中,从来没有对我的 AJAX 资源发出请求。没有发送预检请求,也没有发出实际请求。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,这意味着确实需要进行预检。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。
有谁知道问题可能是什么?非常感谢。
