jQuery.getJSON - Access-Control-Allow-Origin问题 [英] jQuery.getJSON - Access-Control-Allow-Origin Issue
问题描述
我正在使用jQuery的 $。getJSON()
函数来返回一组简短的JSON数据。
I'm jusing jQuery's $.getJSON()
function to return a short set of JSON data.
我已经将JSON数据放在网址上,例如 example.com
。
我没有意识到,但是当我访问同一个url时,无法加载JSON数据。我按照控制台进行操作,发现由于 Access-Control-Allow-Origin
, XMLHttpRequest
无法加载。
I've got the JSON data sitting on a url such as example.com
.
I didn't realize it, but as I was accessing that same url, the JSON data couldn't be loaded. I followed through the console and found that XMLHttpRequest
couldn't load due to Access-Control-Allow-Origin
.
现在,我已经读完了,很多网站只是说使用 $。getJSON()
和这将是解决方法,但显然它没有用。我应该在标题或函数中更改一些内容吗?
Now, I've read through, a lot of sites that just said to use $.getJSON()
and that would be the work around, but obviously it didn't work. Is there something I should change in the headers or in the function?
非常感谢帮助。
推荐答案
这很简单,使用 $。getJSON()
函数,在你的URL中只包括
It's simple, use $.getJSON()
function and in your URL just include
callback =?
callback=?
作为参数。这会将调用转换为进行跨域调用所必需的JSONP。更多信息: http://api.jquery.com/jQuery.getJSON/
as a parameter. That will convert the call to JSONP which is necessary to make cross-domain calls. More info: http://api.jquery.com/jQuery.getJSON/
