我正在向一個HTTPS URL發送一個get請求,不知怎的,我正在為“Set-Cookie”獲取空值.迭代時我可以看到header-key有“set-cookie”但header-value為null.

這是我的代碼：

URL obj = new URL(url);

HttpsURLConnection conn = (HttpsURLConnection) obj.openConnection();

HttpsURLConnection.setFollowRedirects(false);

conn.setRequestProperty("User-Agent", USER_AGENT);

conn.setRequestProperty("Accept",

"text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");

conn.setRequestProperty("Accept-Language", "en-US,en;q=0.5");

conn.setRequestProperty("Connection", "keep-alive");

conn.setRequestProperty("Accept-Encoding", "gzip, deflate");

conn.connect();

Map em = conn.getHeaderFields();

System.out.println("header Values......" + em.toString());

String headerName = null;

for (int i = 1; (headerName = conn.getHeaderFieldKey(i)) != null; i++)

{

System.out.println("Header Nme : " + headerName);

System.out.println(conn.getHeaderField(i));

}

輸出：

header Values......{null=[HTTP/1.1 200 OK], x-wily-info=[Clear guid=0BE0EC9D0A7E67816C471FA946FD2EBB], Date=[Sat, 29 Mar 2014 03:27:41 GMT], Content-Length=[8106], x-wily-servlet=[*******************], X-FRAME-OPTIONS=[SAMEORIGIN], Connection=[close], Content-Type=[text/html;charset=UTF-8]}

Header Nme : Date

Header Nme : X-FRAME-OPTIONS

SAMEORIGIN

Header Nme : x-wily-info

Clear guid=0BE0EC9D0A7E67816C471FA946FD2EBB

Header Nme : x-wily-servlet

*****************************

Header Nme : Content-Type

text/html;charset=UTF-8

Header Nme : Content-Length

8106

**Header Nme : Set-Cookie

null

Header Nme : Set-Cookie

Header Nme : Connection

close

Response Code : 200

從瀏覽器我可以看到：

Connection close

我在許多HTTPS網址上嘗試過相同的操作,所有這些網址都運行正常,這只是創建問題;我注意到的主要區別是這個服務器實際上是以’HttpOnly’的形式發送cookie.它引起了問題嗎？

解決方法:

由于XSS問題,這似乎是一個功能.
