不使用证书的情况下调用ssl的url，服务无法连接

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```

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。
