java - HttpUrlConnection Cookie

Question

我的代码工作正常，但服务器响应 2 个 Set-Cookie。问题是 Session-ID 位于第一个，而 getHeaderField("Set-Cookie") 仅返回最后一个 Set-Cookie。我怎样才能得到第一个？这是我的意思的图片:

import javax.net.ssl.HttpsURLConnection;

import org.omg.CORBA.portable.OutputStream;

public class main {
public static void main(String[] args) throws IOException {
CookieHandler.setDefault(new CookieManager());
String rawData = "";
String type = "application/x-www-form-urlencoded";
URL u = new URL("http://speed.die-kreuzzuege.de/index.php?action=login&user=USERNAME&pw=PW&antibot=&guest=&check=");
HttpURLConnection conn = (HttpURLConnection) u.openConnection();
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty( "Content-Type", type );
java.io.OutputStream os = conn.getOutputStream();

String cookie = conn.getHeaderField("Set-Cookie");
    if (cookie != null)
           System.out.println("cookie: " + cookie)
}
}

Answer 1

尝试使用getHeaderFields() 。它返回 Map<String, List<String>>这样您就可以获得 header 值的列表:

    for(String cookie : conn.getHeaderFields().get("Set-Cookie")){
        System.out.println("cookie: " + cookie);
    }

希望有帮助。
