我正在尝试在我的网站上使用javascript设置SameSite属性。该代码是
<script type="text/javascript">
document.cookie = "AC-C=ac-c;expires=Fri, 31 Dec 9999 23:59:59 GMT;path=/;HttpOnly;SameSite=Lax";
</script>
正在设置cookie，但未设置SameSite属性。知道我在哪里吗？
谢谢

如何从S3加载pickel文件???
我试图在类B中访问类A的静态变量,但是我得到NullPointerException.代码是:
public class OutgoingMessage {
public static SMPPSession session;
public static void main(String [] args)
{
session = new SMPPSession();
}
}
和
public class SendSMS {
public static void main(String [] args)
{
if(OutgoingMessage.session.getSessionState().toString().equals("Connected"))//Line 44
{
}
}
}
错误读取
Exception in thread "main" java.lang.NullPointerException
at SendSMS.main(SendSMS.java:44)
知道我错过了什么吗？
谢谢
