先给大家介绍下vue发送websocket请求和http post请求

直接上代码:

pdf.vue

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>
