HttpUrlConnection Cookie

Question

我的代码工作正常，但服务器返回2个Set-Cookie。问题是会话ID在第一个会话ID中，而getHeaderField(" Set-Cookie ")只返回最后一个Set-Cookie。我怎么才能得到第一个呢？这是我所指的图片：

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()。它返回一个Map<String, List<String>>，这样您就可以获得Headers值的列表：

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

希望能有所帮助。

我的代码

Map<String, List<String>> map = con.getHeaderFields();
            for (Map.Entry<String, List<String>> entry : map.entrySet()) {
                System.out.println("Key : " + entry.getKey() +
                        " ,Value : " + entry.getValue());
            }

            String cookie = con.getHeaderField("Set-Cookie");
            SharedPreferences.Editor editor = mSettings.edit();
            editor.putString(APP_PREFERENCES_COOKIE, cookie);
            editor.apply();
