如何进行跨域 ajax 调用以从 api 获取 xml?

How can i make crossdomain ajax calls to get the xml from the api?

推荐答案

您不能通过跨域调用来获取 XML.接收跨域数据的唯一选择是JSON-P.

You cannot make a crossdomain call to to get XML. Your only choice to receive data crossdomain is JSON-P.

同源策略限制直接访问外域(ajax/iframes)，json-p使用动态脚本标签插入解决此问题.

The same origin policy restricts direct access to a foreign domain (ajax/iframes), json-p uses dynamic script tag insertion to workaround this issue.

看看 http://api.jquery.com/jQuery.getJSON/.JSON-P 也包含在其中.

Have a look at http://api.jquery.com/jQuery.getJSON/. JSON-P is also covered there.
