Java 获取 Session Cookies

Question

Getting header fields from a URLConnection doesn't get session cookies for me.

When I use CookieManager I can get session cookies from a URL:

CookieManager manager = new CookieManager();
manager.setCookiePolicy(CookiePolicy.ACCEPT_ALL);
CookieHandler.setDefault(manager);

URLConnection con = url.openConnection();
con.getContent();

CookieStore cookieJar = manager.getCookieStore();
List<HttpCookie> cookies = cookieJar.getCookies();

This is fine, but I need to send a POST request. So I am writing to the URLConnection's output stream. My question is how to get the session cookies after sending the POST request.

Answer 1

Try using the same CookieManager object with your first and subsequent requests using URLConnection.
