跨域AJAX读取XML

Noobie here. I'm writing a client script that needs to read an XML file from another domain. I tried using JSONP. I get a 200 response but the client can't access the returned data for some reason. I get two errors:

Noobie这里。我正在编写一个客户端脚本，需要从另一个域读取XML文件。我试着使用JSONP。我得到了200个响应，但是由于某些原因，客户端无法访问返回的数据。我得到了两个错误:

Resource interpreted as Script but transferred with MIME type text/xml

and

和

Uncaught SyntaxError: Unexpected token <

Here's the code (I've removed the XML url since it's confidential):

下面是代码(我已经删除了XML url，因为它是机密的):

$(document).ready(function() {
  $.getJSON("urlOfFilecallback=?", function(data) {
  console.log(data)
 })
});

When I try to render the data in the console I get:

当我尝试在控制台呈现数据时，我得到:

ReferenceError: data is not defined

How can I fix this? Do I need to use a proxy?

我该怎么解决这个问题呢?我需要使用代理吗?

3 个解决方案

You don't have to write your own proxy. You can use YQL if you want to here is an example how:

您不必编写自己的代理。如果你想使用YQL，这里有一个例子:

//sample site that returns xml
site = 'http://goo.gl/9iQWyG';


var yql = 'http://query.yahooapis.com/v1/public/yql?q=' + encodeURIComponent('select * from xml where url="' + site + '"') + '&format=xml&callback=?';

// Request that YSQL string, and run a callback function.
// Pass a defined function to prevent cache-busting.
$.getJSON(yql, function(data){
    console.log(data.results[0]);
});

here is the jsfiddle check console.log.

这是jsfiddle检查console.log。

(Usage limits of the public YQL API is 2,000 requests/hour per IP)

(公共YQL API的使用限制是每IP每小时2000个请求)

#2

XML is not allowed for cross-domain requests by default.

默认情况下，不允许XML用于跨域请求。

However, with a little server-side programming you can create a proxy and load the data within your own domain, and output it as XML.

但是，使用少量的服务器端编程，您可以创建代理并在自己的域内加载数据，并将其输出为XML。

If you have access to the other domain side, you could also use this approach Cross Domain Request

如果您可以访问另一个域，您也可以使用这种方法跨域请求
