微信小程序接入腾讯云IM即时通讯(会话列表)

会话列表功能概述:

  • 登录 :先用自己的账号登录腾讯云;
  • 获取会话列表 :登录之后再获取会话列表;
  • 更新未读消息数量 :获取会话列表之后更新未读消息数量

WXML代码(自己写的将就看一下)

    登录主要信息配置

    (我这里是写在app.js里面,这些配置信息是后台服务器端对接完之后返回给前端的,登录的时候要用到)
    var cache = require('./utils/cache.js');
    var login = require('./utils/login.js');
    App({
    data: {
    Config :{
    sdkappid: 1400129031,//
    accountType: 35602,
    accountMode: 0 //帐号模式,0-表示独立模式
    }, },
