Question

我找到了一个httpclient似乎没有处理重定向的网址：

http://news.google.com/news/url?sa=t&fd=R&usg=AFQjCNGrJk-F7Dmshmtze2yhifxRsv8sRg&url=http://www.mtv.com/news/articles/1647243/20100907/story.jhtml

应该302： http://www.mtv.com/news/articles/1647243/20100907/story.jhtml

当我查看浏览器中的标题时，一切看起来都不错：

HTTP/1.1 302 Moved Temporarily
Content-Type: text/html; charset=UTF-8

Connection: close

然而，httpclient似乎没有给我最终的URL。这是我正在使用的代码

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();

我做错了吗？感谢

从httpclient邮件列表中找到答案......

Google不会对HEAD和GET进行相同处理，因此GET会重定向302并且HEAD请求会提供200 OK

HttpClient无法302这个链接？
