一、TCPSocket.js 封装TCP协议

class socket {
  constructor() {
    this.connection = {};
  }
  // 创建一个TCP实例
  establish(monitor) {
    this.connection = wx.createTCPSocket();
    this.connection.connect({ address: "000.000.0.0", port: 6800 });
  }
  // 发送消息
  connect(message) {
    this.connection.onConnect(() => {
      this.connection.write(message);
    });
  }
  // 监听端口函数
  onMessage(success, failure) {
    this.connection.onMessage((res) => {
      success(res)
    });
    this.connection.onError((err) => {
      failure(err);
    });
  }

  // 关闭搜索事件
  TCPclose() {
    setTimeout(() => {
      // 3S后，关闭socket
      this.connection.close(() => {
        console.log("TCP关闭");
      });
    }, 3000);
  }
}
const TCPSocket = new socket();
export default TCPSocket;

二、vue文件中使用TCP文章来源地址https://www.toymoban.com/news/detail-838404.html

<template>
  <view class="zai-box">
        <view class="container">
          <text class="textName">{{ wifiSSID }}</text>
          <input type="text" placeholder="请输入WLAN密码" v-model="password" />
        </view>
        <button
          class="loginButton"
          :loading="loadingWIfi"
          :disabled="JSON.stringify(password.length) < 8 || loadingWIfi"
          @click="settiing"
        >
          {{ loadingWIfi ? "连接中" : "连接" }}
        </button>
  </view>
</template>

<script>
import TCP from "@/common/util/TCPSocket.js";
export default {
  data() {
    return {
      wifiSSID: "WIFI name",
      password: "",

      wifiCountInterval: null,
      wifiCountDown: 0,
      loadingWIfi: false,
    };
  },
  onHide() {
    this.clearInterval();
  },
  methods: {
    settiing() {
      this.loadingWIfi = true;
      this.onConfirm();
    },
    onConfirm() {
      this.wifiCountDown = 60;
      this.startSMSTimer();
      if (this.isFirst) {
        // TCP实例创建
        // 连接端口
        TCP.establish();
        this.isFirst = false;
      }

      // 请求设备上报状态
      this.udpsend();
      // 开始监听
      TCP.onMessage(
        (res) => {
          if (!res) return;
          // 关闭TCP连接
          TCP.TCPclose();
          console.log(res) // 查看返回数据
          
        },
        (err) => {
          // debug
          console.log(err, "err");
        }
      );
    },
    udpsend() {
      const msgData = {
        event: "network",
        data: {
          ssid: this.wifiSSID,
          password: this.password,
        },
      };
      TCP.connect(JSON.stringify(msgData));
    },
    startSMSTimer() {
      this.wifiCountInterval = setInterval(() => {
        this.wifiCountDown--;
        if (this.wifiCountDown <= 0) {
          clearInterval(this.wifiCountInterval);
          this.wifiCountInterval = null;
          // 响应超过60秒后的操作
          // ........
        }
      }, 1000);
    },

        this.wifiCountInterval = null;
