HarmonyOS tls协议支持使用系统默认ca证书代码示例

import { connection, socket } from '@kit.NetworkKit';
import { util } from '@kit.ArkTS';

//tlsSocket连接
tlsSocketConnect() {
  //host地址当前为参考样例，需要根据实际请求替换地址
  let host: string = '192.168.5.14';
  //port当前为参考样例端口号，需要根据实际请求替换
  let port: number = 993;
  let net = connection.hasDefaultNetSync();
  if (!net) {
    //没有连接网络时，打印日志提示
    AlertDialog.show({
      title: '网络连接失败',
      message: '网络连接失败，请检查网络连接状态',
    })
    return;
  }
  let tlsSocket = socket.constructTLSSocketInstance();
  let tlsConnectOptions: socket.TLSConnectOptions = {
    address: {
      address: host,
      port: port
    },
    secureOptions: {
    }
  }
  tlsSocket.on('message', (msgFromServer) => {
    let uint8Array = new Uint8Array(msgFromServer.message);
    let textDecoder = util.TextDecoder.create();
    let res = textDecoder.decodeWithStream(uint8Array);
    console.log(' get data from server : ' + JSON.stringify(res));
    // 业务处理完毕,关闭tlsSocket通道
    tlsSocket.close().then(() => {
      console.log('tlsSocket close success');
    })
  })
  // 注册连接事件
  tlsSocket.on('connect', () => {
    console.log('tlsSocket start connect');
  })
  // 开始连接服务器
  tlsSocket.connect(tlsConnectOptions).then(() => {
    console.log('tlsSocket connect success');
    // 发送业务数据
    tlsSocket.send("test msg").then(() => {
      console.log('tlsSocket send success');
    })
  })
}
