获取群列表成功后，本地存储群组id(GroupId)。获取历史聊天记录。
//读取群组基本资料-高级接口
getGroupInfo(group_id, cbOK, cbErr) {

group_id

'MemberInfoFilter': [

'Role',
'JoinTime',
'LastSendMsgTime',
'ShutUpUntil'
]
};
webim.getGroupInfo(
options,
function(resp) {
if (resp.GroupInfo[0].ShutUpAllMember == 'On') {
console.log('该群组已开启全局禁言');
}
if (cbOK) {
cbOK(resp);
}
},
function(err) {
console.log(err.ErrorInfo);
}
);
},
获取最新的群历史消息,用于切换群组聊天时，重新拉取群组的聊天消息
getLastGroupHistoryMsgs: function() {

that.getGroupInfo(selToID, function(resp) {
var reqMsgCount = 20;
that.setData({
reqMsgSeq: resp.GroupInfo[0].NextMsgSeq - 1
})
//拉取最新的群历史消息
var options = {
'GroupId': selToID,
'ReqMsgSeq': resp.GroupInfo[0].NextMsgSeq - 1,
'ReqMsgNumber': reqMsgCount,
};
webim.syncGroupMsgs(
options,
function(msgList) {

console.log("该群没有历史消息了:options=" + JSON.stringify(options));
return;
}
var msgLists = [];

接下来处理一下，聊天页面增加一条消息。
上篇中有介绍到监听新消息事件。
//处理消息（私聊(包括普通消息和全员推送消息)，普通群(非直播聊天室)消息） 我这里是只要私聊的
addMsg: function(msg) {
var that = this;
var fromAccount, fromAccountNick, sessType, subType;
fromAccount = msg.getFromAccount();
if (!fromAccount) {
fromAccount = '';
}
fromAccountNick = msg.getFromAccountNick();
if (!fromAccountNick) {
fromAccountNick = fromAccount;
}
//解析消息
//获取会话类型
//webim.SESSION_TYPE.GROUP-群聊，
//webim.SESSION_TYPE.C2C-私聊，
sessType = msg.getSession().type();
//获取消息子类型
//会话类型为群聊时，子类型为：webim.GROUP_MSG_SUB_TYPE
//会话类型为私聊时，子类型为：webim.C2C_MSG_SUB_TYPE
subType = msg.getSubType();
switch (sessType) {
case webim.SESSION_TYPE.GROUP: //私聊消息
switch (subType) {
case webim.GROUP_MSG_SUB_TYPE.COMMON: //c2c普通消息
that.convertMsg(msg); //解析方法
break;
case webim.GROUP_MSG_SUB_TYPE.TIP: //c2c普通消息

break;
}
break;
}
},
convertMsg: function(msg) {
var that = this;
var elems, elem, type, content, isSelfSend;
var loginInfo = that.data.loginInfo; //自己的资料
var friendInfo = that.data.friendInfo; //对方的资料，这里要特别注意一下，消息里面是不会返回双方的头像和昵称的，只能通过指定的方法得到。
elems = msg.getElems();
isSelfSend = msg.getIsSend(); //消息是否为自己发的 true是自己发送，
var sess = msg.sess;
var currentMsg = {}; //设置消息数组，存消息
var currentMsgsArray = that.data.msgList;
var allChatList = that.data.allChatList;
for (var i in elems) {
elem = elems[i];
type = elem.getType();
content = elem.getContent();
switch (type) {
case webim.MSG_ELEMENT_TYPE.TEXT:
var msgContent = content.text;
console.log(content)
var msgTime = msg.getTime(); //得到当前消息发送的时间
//得到当天凌晨的时间戳
var timeStamp = new Date(new Date().setHours(0, 0, 0, 0)) / 1000;

}
//得到月份和天 月份一般是从0开始，所以展示出来要+1
var month = d.getMonth();
var day = d.getDate();
//得到时间 当天时间应该只显示时分 当天以前显示日期+时间
thisdate = ('2019-' +(month + 1) + '-' + day + ' ' + hour + ":" + min);
currentMsg.text = msgContent; //当前消息的内容
currentMsg.type = type;
currentMsg.images = images;
currentMsg.time = thisdate;
currentMsg.isSend = isSelfSend;
currentMsg.name = msg.fromAccountNick;
if (msg.fromAccountHeadurl==null){
var avatarUrl = '../../images/noavatar.png';
}else{
var avatarUrl = msg.fromAccountHeadurl;
}
console.log(currentMsg)
//根据是否自己发送的消息，设置双方的头像
if (isSelfSend == true) {
currentMsg.avatarUrl = avatarUrl;
} else {
currentMsg.avatarUrl = avatarUrl;
}
//然后将每一条聊天消息push进数组
currentMsgsArray.push(currentMsg);
that.setData({
msgList: currentMsgsArray,
})
break;
}
}
},
