我发现 httpclient 似乎没有处理重定向的 URL：
应 302 至： http ://www.mtv.com/news/articles/1647243/20100907/story.jhtml
当我查看浏览器中的标题时，一切看起来都很好：
HTTP/1.1 302 Moved Temporarily

但是 httpclient 似乎没有给我最终的 URL。这是我使用的代码
HttpHead httpget = null;
HttpHost target = null;
HttpUriRequest req = null;
String startURL = "http://news.google.com/news/url?sa=t&fd=R&usg=AFQjCNGrJk-F7Dmshmtze2yhifxRsv8sRg&url=http://www.mtv.com/news/articles/1647243/20100907/story.jhtml";
HttpContext localContext = new BasicHttpContext();
localContext.setAttribute(ClientContext.COOKIE_STORE,HttpClientFetcher.emptyCookieStore);
httpget = new HttpHead(startURL);
HttpResponse response = httpClient.execute(httpget, localContext);
Header[] test = response.getAllHeaders();
for(Header h: test) {
logger.info(h.getName()+ ": "+h.getValue());
}
target = (HttpHost) localContext.getAttribute( ExecutionContext.HTTP_TARGET_HOST );
req = (HttpUriRequest) localContext.getAttribute( ExecutionContext.HTTP_REQUEST );
// STILL PRINTS OUT THE GOOGLE NEWS LINK
finalURL = target+""+req.getURI();
难道我做错了什么？谢谢
