Android 使用CORS/jQuery mobile/phonegap获取RSS提要
我正在尝试向我用Phonegap制作的应用程序添加RSS提要。导入提要时遇到问题,请求的资源上存在“No‘Access Control Allow Origin’头。”错误。这是否意味着我已正确设置了所有内容,但由于服务器不支持,我无法获取它?最终,我希望rss提要是一个谷歌日历事件列表,那么这就是我应该如何处理这个问题的方式吗?下面是我的get函数代码Android 使用CORS/jQuery mobile/phonegap获取RSS提要,android,jquery-mobile,cordova,rss,Android,Jquery Mobile,Cordova,Rss,我正在尝试向我用Phonegap制作的应用程序添加RSS提要。导入提要时遇到问题,请求的资源上存在“No‘Access Control Allow Origin’头。”错误。这是否意味着我已正确设置了所有内容,但由于服务器不支持,我无法获取它?最终,我希望rss提要是一个谷歌日历事件列表,那么这就是我应该如何处理这个问题的方式吗?下面是我的get函数代码 get_blog_data: function(){ var app = this; $.ajax({

},CORS是web浏览器的一个限制,不允许您从给定页面向另一个域发出请求。这将阻止您从页面获取RSS提要 唯一的解决方法是使用类似的提要API,将RSS提要转换为JSON,然后通过JSONP进行查询
