Socket连接

代码实现

import socket from '@ohos.net.socket';@Entry@Componentstruct SocketPage {  build() {    Row() {      Column() { Text( '启动服务端')   .fontSize(30)   .backgroundColor(Color.Red)   .width('80%')   .height(80)   .fontWeight(FontWeight.Bold)   .onClick(() => {     let udp = socket.constructUDPSocketInstance();     udp.bind({ address: 'localhost', port: 8088 }, err =>{if (err){  console.log('server bind fail:' + JSON.stringify(err));}console.log('server bind success');     });     udp.on("message", value =>{console.log("server message:" + value.message + ", remoteInfo:" + JSON.stringify(value.remoteInfo));     })   }) Text( '启动客户端')   .fontSize(30)   .width('80%')   .height(80)   .margin({top : 50})   .fontWeight(FontWeight.Bold)   .onClick(() => {     let udp = socket.constructUDPSocketInstance();     //TODO 如果bind 则send fail:{"code":22},反之send fail:{"code":88}     udp.bind({address:'localhost'})     let send = udp.send({data: 'Hello, server!',address: {  address: 'localhost',  port : 8088}     })     send.then(() => {console.log('client send success');     }).catch(err => {console.log('client send fail:' + JSON.stringify(err));     });     udp.on("message", value =>{console.log("client message:" + value.message + ", remoteInfo:" + JSON.stringify(value.remoteInfo));     })   })      }      .width('100%')    }    .height('100%')  }}
