Android JavaMail CertPathValidatorException

Question

我的发送电子邮件去年可以正常工作，但我想知道为什么它现在给了我一个 CertPathValidatorException

更新：我尝试使用 Mkyong 的教程 (TLS) + Overriding socketfactory。但是它给了我一个不同的例外。

堆栈：

这是我的新 sendEmail()：

 private boolean sendEmail(String from, String to, String subject, String body){
        final String username = activity.getResources().getString(R.string.feedback_sender_email);
        final String password = activity.getResources().getString(R.string.feedback_sender_password);

        Properties props = new Properties();
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.host", "smtp.gmail.com");
        props.put("mail.smtp.port", "587");
        props.put("mail.smtp.socketFactory.class",
                "com.sblive.connector.MySSLSocketFactory");

        Session session = Session.getInstance(props,
                new javax.mail.Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication(username, password);
                    }
                });

        try {

            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress(from));
            message.setRecipients(Message.RecipientType.TO,
                    InternetAddress.parse(to));
            message.setSubject(subject);
            message.setText(body);
            Transport.send(message);
            return true;
        } catch (MessagingException e) {
            e.printStackTrace();
            return false;
        }

Answer 1

您不信任服务器证书。先看看那里

Send Email in Service (without prompting user)

它对我有用。

其他解决方案：

信任服务器证书

将其导入您的信任存储区，然后使用 javax.net.ssl.trustStore* 系统属性指定信任策略（全局 jre 应该可以）。

通过属性忽略服务器身份

 props.put("mail.transport.protocol", "smtps");
 props.put("mail.smtps.ssl.checkserveridentity", "false");
 props.put("mail.smtps.ssl.trust", "*");

或 how to ignore server cert error in javamail

重写 SocketFactory 以忽略服务器证书

使用

 props.put("mail.smtp.socketFactory.class", "MySSLSocketFactory ");

和

public class MySSLSocketFactory extends SSLSocketFactory {
    SSLContext sslContext = SSLContext.getInstance("TLS");

    public MySSLSocketFactory(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
        super(truststore);

        TrustManager tm = new X509TrustManager() {
            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };

        sslContext.init(null, new TrustManager[] { tm }, null);
    }

    @Override
    public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException, UnknownHostException {
        return sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);
    }

    @Override
    public Socket createSocket() throws IOException {
        return sslContext.getSocketFactory().createSocket();
    }
}
