有没有办法在不获取内容正文的情况下发出 GET 请求？
我正在尝试执行 HEAD 请求来跟踪 302 链接，但是此链接： http://news.google.com/news/url?sa=t&fd =R&usg=AFQjCNGrJk-F7Dmshmtze2yhifxRsv8sRg&url=http://www.mtv.com/news/articles/1647243/20100907/story.jhtml
很麻烦，因为 HEAD 请求返回 200 OK 和 GET 请求返回预期的 302 状态代码。
因此，我需要执行 GET 请求，但我不想支付因获取整个 HTML 文档而产生的额外带宽时间。有人知道如何在不返回正文的情况下进行 GET 操作吗？
更新：采纳了 David 的建议，做了 Range 标头，但他们似乎仍然忽略它

I'm trying to do HEAD requests to follow 302 links, however this link: http://news.google.com/news/url?sa=t&fd=R&usg=AFQjCNGrJk-F7Dmshmtze2yhifxRsv8sRg&url=http://www.mtv.com/news/articles/1647243/20100907/story.jhtml
is troublesome because a HEAD request returns a 200 OK and a GET request returns the expected 302 Status code.
So I'll need to do a GET request but I'd rather not have to pay for the extra bandwidth times that will come from getting the entire HTML document. Anyone know a hack to do a GET without getting the body returned?
UPDATE: took David's advice to do a Range header but they seem to still be ignoring it

尝试在请求中使用 Range 标头。
如果这不起作用，您可以在获得所需的标头后挂断连接吗？
File a bug with the web server's owner.
Try using the Range header in your request.
If that doesn't work, can you just hang up the connection after you get the headers you want?
在您引用的具体示例中，您可以将其从原始 URL 的“url”参数中提取出来。但对于更通用的方法，我会坚持 David M. 的建议
In the specific example you cite, you could just pull it out of the original URL's "url" parameter. But for a more generic approach, I'd stick to David M.'s suggestions
