vue发送websocket请求和http post请求的实例代码

先给大家介绍下vue发送websocket请求和http post请求

直接上代码：

              alert("合闸成功！");
            }else{
              alert("合闸失败！请联系管理员");
            }379           })
          .catch(error => {
            console.log(error)
          })
      },
      fenzha() {
        alert("分闸"); //3#楼3AA-4_分闸
      }
    },
    mounted() {
      this.initWebSocket();
    },
    beforeDestroy: function() { // 页面离开时断开连接,清除定时器
      this.disconnect();
      clearInterval(this.timer);
    },
    created() {

    }
  }
</script>

在main.js设置全局http地址：

Axios.defaults.baseURL = 'http://XXX.XXX.XX.XXX:9001';
Axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';

在main.js中设置header中token值：

// 添加请求拦截器
Axios.interceptors.request.use(function(config) {
  config.headers.access_token = "add7c097-f12b-40fe-8e48-6fe1f2120fa5";
  //  config.headers.Authorization = localStorage.token; //将token设置成请求头
  console.log("请求============" + config);
  // 在发送请求之前做些什么
  return config;
}, function(error) {
  // 对请求错误做些什么
  return Promise.reject(error);
});

数据刷起来！

ps：下面给大家介绍下vue websocket 请求

首先写一个公共方法

socket.js

function getSocket(url, params, callback) {
  let socket;
  if (typeof (WebSocket) === 'undefined') {
    console.log('您的浏览器不支持WebSocket');
  } else {
    console.log('您的浏览器支持WebSocket');
    // 初始化 WebSocket 对象，指定要连接的服务器地址与端口建立连接
    socket = new WebSocket(url);
    // 打开事件
    socket.onopen = function() {
      console.log('Socket 已打开');
      socket.send(params);
    };
    // 获得消息事件
    socket.onmessage = function(msg) {
      // 发现消息进入, 开始处理前端触发逻辑
      callback(msg, socket);
    };
    // 关闭事件
    socket.onclose = function() {
      console.log('Socket 已关闭');
    };
    // 发生了错误事件
    socket.onerror = function() {
      console.log('Socket 发生了错误,请刷新页面');
      // 此时可以尝试刷新页面
    };
  }
}
export {
  getSocket
};

使用

test.vue

<script>
import {getSocket} from '@/utils/socket.js';
export default {
  data() {
    return {
      wsData: {}, // 保存 websocket 数据对象
      form: { // 表单
        name: '',
        age: ''
      }
    }
  },
  beforeDestroy() {
    this.wsData.close(); // 关闭 websocket
  },
  created() {
    this.getSocketData();
  },
  methods: {
    // 获取数据
    getSocketData() {
      let params = this.form;
      getSocket(
        `ws://path`,
        JSON.stringify(params),
        (data, ws) => {
          console.log(data, ws);
          // 保存数据对象, 以便发送消息
          this.wsData = ws;
        }
      );
    },
    // 发送数据
    sendSocketData() {
      let params = this.form;
      params.name = 'xx';
      params.age= '18';
      this.wsData.send(JSON.stringify(params));
    }
  }
}
</script>
