本文通過例項為大家分享了微信小程式實現聊天室的具體程式碼，供大家參考，具體內容如下

1.實現效果展示

2.room.wxml

<view class="container" style="{{containerStyle}}">
  <chatroom
    style="width: 100%; height: 100%YAapD"
    envId="{{chatRoomEnvId}}"
    collection="{{chatRoomCollection}}"
    groupId="{{chatRoomGroupId}}"
    groupName="{{chatRoomGroupName}}"
    userInfo="{{userInfo}}"
    onGetUserInfo="{{onGetUserInfo}}"
    getOpenID="{{getOpenID}}"
  ></chatroom>
</view>

3.room.js

const app = getApp()

Page({
  data: {
    avatarUrl: './user-unlogin.png',userInfo: null,logged: false,takeSession: false,requestResult: '',// chatRoomEnvId: 'release-f8415a',chatRoomCollection: 'chatroom',chatRoomGroupId: 'demo',chatRoomGroupName: '聊天室',// functions for used in chatroom components
    onGwww.cppcns.com
 
etUserInfo: null,getOpenID: null,},onLoad: function() {
    // 獲取使用者資訊
    wx.getSetting({
      success: res => {
        if (res.authSetting['scope.userInfo']) {
          // 已經授權，可以直接呼叫 getUserInfo 獲取頭像暱稱，不會彈框
          wx.getUserInfo({
            success: res => {
              this.setData({
                avatarUrl: res.userInfo.avatarUrl,userInfo: res.userInfo
              })
            }
          })
        }
      }
    })

    this.setData({
      onGetUserInfo: this.onGetUserInfo,getOpenID: this.getOpenID,})

    wx.getSystemInfo({
      success: res => {
        console.log('system info',res)
        if (res.safeArea) {
          const { top,bottom } = res.safeArea
          this.setData({
            containerStyle: `padding-top: ${(/ios/i.test(res.system) ? 10 : 20) + top}px; padding-bottom: ${

        }
      },})
  },getOpenID: async functiohttp://www.cppcns.comn() {

    const { result } = await wx.cloud.callFunction({
      name: 'login',})

    return result.openid
  },onGetUserInfo: function(e) {

    }
  },onShareAppMessage() {
    return {
      title: '即時通訊 Demohttp://www.cppcns.com',path: '/pages/im/room/room',}
  },})

4.room.json

{
  "usingComponents": {
    "chatroom": "/components/chatroom/chatroom"
  }
}

5.room.wxss

.container {
  height: 100%;
