jQuery无法从localhost检索数据

I have a very simple bit of jQuery to retrieve my latest Tweet

我有一个非常简单的jQuery来检索我最新的推文

$.getJSON("http://twitter.com/statuses/user_timeline/username.json?count=1", 
           function(data) {
              $("#tweet_text").html(data[0].text);
           });

This works fine on a simple HTML file on my desktop. However, once the file is accessed from my localhost (apache) no data is being returned. I was wondering if any part of Apache was blocking the request somehow? Or any other ideas?

这适用于我桌面上的简单HTML文件。但是,一旦从我的localhost(apache)访问该文件,就不会返回任何数据。我想知道Apache的任何部分是否以某种方式阻止了这个请求?还是其他任何想法?

JavaScript cannot currently make direct requests cross-domain due to the Same-origin Policy.

由于同源策略,JavaScript目前无法跨域直接请求。

You're best bet is probably to look into JSONP for this.

你最好的选择可能是为了研究JSONP。

You can find more information on it from both jQuery:

您可以从jQuery中找到有关它的更多信息:

If the URL includes the string "callback=?" in the URL, the request is treated as JSONP instead. See the discussion of the jsonp data type in $.ajax() for more details.

如果URL包含字符串“callback =?”在URL中,请求被视为JSONP。有关更多详细信息,请参阅$ .ajax()中有关jsonp数据类型的讨论。

and Twitter:

Parameters:

callback: Optional. Only available for JSON format. If supplied, the response will use the JSONP format with a callback of the given name.
回调:可选。仅适用于JSON格式。如果提供,响应将使用具有给定名称回调的JSONP格式。

Example: http://search.twitter.com/search.json?callback=foo&q=twitter

Hope this helps.

希望这可以帮助。

Correction...

If status/user_timeline supports JSONP, it's not documented as such.

如果status / user_timeline支持JSONP,则不会记录它。

You may have to look into setting up a Cross-Domain Proxy to get the data you want.

您可能需要考虑设置跨域代理以获取所需的数据。
