Question

我有以下代码：

package daoImp;

import java.util.List;

import javapns.Push;
import javapns.communication.exceptions.KeystoreException;
import javapns.notification.PushedNotification;
import javapns.notification.ResponsePacket;
import org.json.JSONException;
import com.sun.jmx.snmp.daemon.CommunicationException;

public class Notification {

    public static void main(String args[]) {
        try {
            new Notification().sendMessageToAPN();
        } catch (CommunicationException | KeystoreException | JSONException
                | javapns.communication.exceptions.CommunicationException e) {
            e.printStackTrace();
        }
    }

    public void sendMessageToAPN() throws CommunicationException,
            KeystoreException, JSONException,
            javapns.communication.exceptions.CommunicationException {
        String regId1 = "6f9d340ab4d0f81206f7d8c1ab7b8994d90d139e0d1d2b99999b02887e60d54f";
        List<PushedNotification> notifications = Push.alert("hello","C:/Program Files (x86)/Java/jdk1.7.0_21/jre/lib/security/gameover.p12", "gameover",
                false, regId1);
        for (PushedNotification notification : notifications) {
            if (notification.isSuccessful()) {
                System.out.println("Push notification sent successfully to: " + notification.getDevice().getToken());

            } else {
                String invalidToken = notification.getDevice().getToken();
                System.err.println("Invalid Token " + invalidToken);

                System.out.println(" The problem was");
                Exception theProblem = notification.getException();
                theProblem.printStackTrace();

                ResponsePacket theErrorResponse = notification.getResponse();
                if (theErrorResponse != null) {
                    System.out.println(theErrorResponse.getMessage());
                }
            }
        }
    }
}

当我运行代码时，我收到以下异常消息：handshake to ssl failed as connection to remote host failed during handshake。

log4j:WARN No appenders could be found for logger (javapns.notification.Payload).
log4j:WARN Please initialize the log4j system properly.

我不知道为什么我收到这条消息。

Answer 1

javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
Caused by: java.io.EOFException: SSL peer shut down incorrectly

Above Exception is a generic exception we get in the client if there is any of below scenario:

If Server and Client support different version of TLS e.g. server support TLS2 while Client support only TLS1. This issue can be resolved by setting below property in Client side :

System.setProperty("https.protocols", "TLSv1,TLSv1.1,TLSv1.2");

If the server is not able to validate the certificate chain of the client, then also it will close the conection.

Certificate chain qtp510727907-31, fatal error: 42: null cert chain javax.net.ssl.SSLHandshakeException: null cert chain %% Invalidated: [Session-3, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA]
qtp510727907-31, SEND TLSv1 ALERT: fatal, description = bad_certificate qtp510727907-31, WRITE: TLSv1 Alert, length = 2
main, WRITE: TLSv1 Change Cipher Spec, length = 1 qtp510727907-31, fatal: engine already closed. Rethrowing
javax.net.ssl.SSLHandshakeException: null cert chain

To know the exact cause of failure, we need to enable -Djavax.net.debug=all while executing the client call towards the server.

Answer 2

我相信你错过了证书。

您可以使用InstallCerts应用生成它们。（http://miteff.com/install-cert）

或http://opentox.ntua.gr/blog/77-ssl-certificates

获得证书后，您需要将其放在jdk家中的安全目录下，例如：

C：\ Program Files \ Java \ jdk1.6.0_45 \ jre \ lib \ security

希望这可以解决您的问题

发生此问题是由于Internet连接问题/ Internet连接不良。请检查您的互联网连接。
