Question

我希望通过此代码

获取响应标头中的位置值

HttpGet getRequest = null;
CloseableHttpResponse response = null;
getRequest = new HttpGet("https://wl-prod.sabresonicweb.com/SSW2010/B3QE/webqtrip.html?searchType=NORMAL&journeySpan=RT&origin=SGN&destination=DAD&departureDate=2016-01-31&returnDate=2016-02-01&numAdults=2&numChildren=0&numInfants=0&alternativeLandingPage=true&promoCode=&lang=vi_VN");
getRequest.setHeader("Host", "wl-prod.sabresonicweb.com");
getRequest.setHeader("User-Agent", defaultUserAgent);
getRequest.setHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
getRequest.setHeader("Accept-Language", "en-US,en;q=0.5");
getRequest.setHeader("Accept-Encoding", "gzip, deflate");
getRequest.setHeader("Referer", "http://vietnamairlines.com/");
getRequest.setHeader("Connection", "keep-alive");

response = httpClient.execute(getRequest, context);
Header[] headers = response.getAllHeaders();
for (Header header : headers) {
    System.out.println("Key : " + header.getName() 
          + " ,Value : " + header.getValue());
}

然而，我收到的结果是：

密钥：缓存控制，值：无缓存 Key：Expires，Value：Thu，1970年1月1日00:00:00 GMT 键：X-FRAME-OPTIONS，值：SAMEORIGIN 关键词：Pragma，价值：无缓存密钥：缓存控制，值：无存储密钥：内容类型，值：text / html; charset = UTF-8 密钥：转移编码，价值：分块 密钥：Vary，Value：Accept-Encoding 关键：日期，价值：周六，05 Dec 2015 08:36:16 GMT 密钥：服务器，价值：

当我使用Fiddler时，我可以像这样得到位置响应标头的值：

HTTP/1.1 302 Found
Cache-Control: no-cache
Expires: Thu, 01 Jan 1970 00:00:00 GMT
X-FRAME-OPTIONS: SAMEORIGIN
Pragma: no-cache
Cache-Control: no-store

如何通过HttpClient Get方法获取响应标头中的位置值？

通过HttpClient获取在响应标头中分块的Transfer-Encoding
