不使用证书的情况下调用ssl的url，服务无法连接

先从 Node 客户端构造函数及其 tlsAllowInsecureConnection 和 tlsValidateHostname 选项开始，然后在启用客户端日志记录的情况下，针对 pulsar+ssl 服务 URL 重现提供的订阅示例。将连接失败和分区元数据失败与 Java 的行为进行比较；当禁用证书验证后，Node 客户端能够连接并创建消费者而不出现 ConnectError 时，即表示完成。

以下是node代码，在java中是可以通过```
PulsarClient client = PulsarClient.builder().serviceUrl(brokerServerUrl).allowTlsInsecureConnection(true)
.authentication(new IoTAuthentication(iotAccessId, iotSecretKey)).build();
Consumer consumer = client.newConsumer(Schema.STRING).topic(String.format("%s/iot/event", iotAccessId))
.subscriptionName(subscriptionName).subscriptionType(SubscriptionType.Failover)
.autoUpdatePartitions(Boolean.FALSE).subscribe();

这种方式来跳过ssl证书的，在下面node中我也加入了tlsAllowInsecureConnection: true,
            tlsValidateHostname: false,这两个参数但是无法连接到服务



`const Pulsar = require('pulsar-client');
const crypto = require('crypto');
const iotAccessId = "yGmZyJnpqPPIGwzj1564";
const iotSecretKey="b9fab8817fa64f4ab6424d6a7035d2e7";
const brokerSSLServerUrl = "pulsar+ssl://iot-north-mq.heclouds.com:6651/";
const iotSubscriptionName="yGmZyJnpqPPIGwzj1564-sub";

const token = JSON.stringify({
    tenant: iotAccessId,
    password: sha256(iotAccessId + sha256(iotSecretKey)).substring(4, 20)
});

(async () => {
    try {
        console.log("token:", token);
        // Create a client
        let authenticationToken = new Pulsar.AuthenticationToken({
            token: token
        });

        Pulsar.Client.setLogHandler((level, file, line, message) => {
            console.log('[%s][%s:%d] %s', Pulsar.LogLevel.toString(level), file, line, message);
        });

        const client = new Pulsar.Client({
            serviceUrl: brokerSSLServerUrl,
            authentication: authenticationToken,
            tlsAllowInsecureConnection: true,
            tlsValidateHostname: false,
        });


        console.log("client:", client);

        // Create a consumer
        const consumer = await client.subscribe({
            topic: `${iotAccessId}/iot/event`,
            // topic: 'persistent://yGmZyJnpqPPIGwzj1564/iot/event-partition-0',
            subscription: iotSubscriptionName,
            subscriptionType: 'Failover'
        });

        console.log("consumer:", consumer);

        // Receive the message
        const msg = await consumer.receive();
        console.log(msg.getData().toString());
        consumer.acknowledge(msg);

        await consumer.close();
        await client.close();
    } catch (error) {
        console.error("An error occurred:", error.message);
        console.error(error.stack);
    }
})();

function sha256(data) {
    return crypto.createHash('sha256').update(data, 'utf8').digest('hex');
}`


最下面是报错信息```
