HarmonyOS socket.TLSSocket发送Uint8Array对象

接收消息可以参考demo：

import socket from "@ohos.net.socket";
import { BusinessError } from '@ohos.base';
let tls: socket.TLSSocket = socket.constructTLSSocketInstance();
class SocketInfo {
  message: ArrayBuffer = new ArrayBuffer(1);
  remoteInfo: socket.SocketRemoteInfo = {} as socket.SocketRemoteInfo; }
let messageView = '';
tls.on('message', (value: SocketInfo) => {
  for (let i: number = 0; i < value.message.byteLength; i++) {
    let uint8Array = new Uint8Array(value.message)
    let messages = uint8Array[i] let message = String.fromCharCode(messages);
    messageView += message; }
  console.log('on message message: ' + JSON.stringify(messageView));
  console.log('remoteInfo: ' + JSON.stringify(value.remoteInfo)); });

监听到的message，就是arrayBuffer类型，只是为了输出messageView这个String类型，再收到arrayBuffer类型之后，显示转了uint8Array，然后转String。
