融云聊天 WEB端

1.引入融云相关ＪＳ文档，这个不难理解。我建议一定要引最新版本。

<script src="http://cdn.ronghub.com/RongIMLib-2.2.5.min.js"></script>

2.在初次加载融云中我们所要做的事情：

RongIMClient.init("appkey");//这是初始化，需要填参数就是你的APPKEY。这个不难理解。
var token = "";//注册时的token

3.链接融云的服务器。

RongIMClient.connect(token,
         {
                onSuccess: function(userId) {

                console.log("Login successfully." + userId);
        },
        onTokenIncorrect: function() {
            console.log('token无效');
        },
        onError:function(errorCode){
                var info = '';
                switch (errorCode) {
                case RongIMLib.ErrorCode.TIMEOUT:
                    info = '超时';
                    break;
                case RongIMLib.ErrorCode.UNKNOWN_ERROR:
                    info = '未知错误';
                    break;
                case RongIMLib.ErrorCode.UNACCEPTABLE_PaROTOCOL_VERSION:
                    info = '不可接受的协议版本';
                    break;
                case RongIMLib.ErrorCode.IDENTIFIER_REJECTED:
                    info = 'appkey不正确';
                    break;
                case RongIMLib.ErrorCode.SERVER_UNAVAILABLE:
                    info = '服务器不可用';
                    break;
                }
                console.log(errorCode);
            }
      });

4.设置消息监听

// 设置连接监听状态 （ status 标识当前连接状态）
 // 连接状态监听器
 RongIMClient.setConnectionStatusListener({
    onChanged: function (status) {
        switch (status) {
            //链接成功
            case RongIMLib.ConnectionStatus.CONNECTED:
                console.log('链接成功');
                break;
            //正在链接
            case RongIMLib.ConnectionStatus.CONNECTING:
                console.log('正在链接');
                break;
            //重新链接
            case RongIMLib.ConnectionStatus.DISCONNECTED:
                console.log('断开连接');
                break;
            //其他设备登陆
            case RongIMLib.ConnectionStatus.KICKED_OFFLINE_BY_OTHER_CLIENT:
                console.log('其他设备登陆');
                break;
              //网络不可用
            case RongIMLib.ConnectionStatus.NETWORK_UNAVAILABLE:
              console.log('网络不可用');
              break;
            }
    }});

 // 消息监听器
 RongIMClient.setOnReceiveMessageListener({
    // 接收到的消息
    onReceived: function (message) {
        // 判断消息类型
        switch(message.messageType){
            case RongIMClient.MessageType.TextMessage:
                   console.log(message.content.content);
                //发送的消息内容将会被打印
                break;
            case RongIMClient.MessageType.ImageMessage:
                // do something...
                break;
            case RongIMClient.MessageType.DiscussionNotificationMessage:
                // do something...
                break;
            case RongIMClient.MessageType.LocationMessage:
                // do something...
                break;
            case RongIMClient.MessageType.RichContentMessage:
                // do something...
                break;
            case RongIMClient.MessageType.DiscussionNotificationMessage:
                // do something...
                break;
            case RongIMClient.MessageType.InformationNotificationMessage:
                // do something...
                break;
            case RongIMClient.MessageType.ContactNotificationMessage:
                // do something...
                break;
            case RongIMClient.MessageType.ProfileNotificationMessage:
                // do something...
                break;
            case RongIMClient.MessageType.CommandNotificationMessage:
                // do something...
                break;
            case RongIMClient.MessageType.CommandMessage:
                // do something...
                break;
            case RongIMClient.MessageType.UnknownMessage:
                // do something...
                break;
            default:
                // 自定义消息
                // do something...
        }
    }
});

5.发送消息

// 定义消息类型,文字消息使用 RongIMLib.TextMessage
var msg = new RongIMLib.TextMessage({content:"hello",extra:"附加信息"});
 //或者使用RongIMLib.TextMessage.obtain 方法.具体使用请参见文档
 //var msg = RongIMLib.TextMessage.obtain("hello");
 var conversationtype = RongIMLib.ConversationType.PRIVATE; // 私聊
 var targetId = "xxx"; // 目标 Id
 RongIMClient.getInstance().sendMessage(conversationtype, targetId, msg, {
                // 发送消息成功
                onSuccess: function (message) {
                    //message 为发送的消息对象并且包含服务器返回的消息唯一Id和发送消息时间戳
                    console.log("Send successfully");
                },
                onError: function (errorCode,message) {
                    var info = '';
                    switch (errorCode) {
                        case RongIMLib.ErrorCode.TIMEOUT:
                            info = '超时';
                            break;
                        case RongIMLib.ErrorCode.UNKNOWN_ERROR:
                            info = '未知错误';
                            break;
                        case RongIMLib.ErrorCode.REJECTED_BY_BLACKLIST:
                            info = '在黑名单中，无法向对方发送消息';
                            break;
                        case RongIMLib.ErrorCode.NOT_IN_DISCUSSION:
                            info = '不在讨论组中';
                            break;
                        case RongIMLib.ErrorCode.NOT_IN_GROUP:
                            info = '不在群组中';
                            break;
                        case RongIMLib.ErrorCode.NOT_IN_CHATROOM:
                            info = '不在聊天室中';
                            break;
                        default :
                            info = x;
                            break;
                    }
                    console.log('发送失败:' + info);
                }
            }
        );

7.融云不提供聊天的样式所以聊天框还是需要我们自己去设置的

CSS:

div.speech {
    margin: 10px 0;
    padding: 8px;
    table-layout: fixed;
    word-break: break-all;
    position: relative;
    background: -webkit-gradient( linear, 50% 0%, 50% 100%, from(#ffffff), color-stop(0.1, #ececec), color-stop(0.5, #dbdbdb), color-stop(0.9, #dcdcdc), to(#8c8c8c) );
    border: 1px solid #989898;
    -webkit-border-radius: 8px;
    -moz-border-radius: 8px;
    border-radius: 8px;
  }
  div.speech:before {
    content: '';
    position: absolute;
    width: 0;
    height: 0;
    left: 15px;
    top: -20px;
    border: 10px solid;
    border-color: transparent transparent #989898 transparent;
  }
  div.speech:after {
    content: '';
    position: absolute;
    width: 0;
    height: 0;
    left: 17px;
    top: -16px;
    border: 8px solid;
    border-color: transparent transparent #ffffff transparent;
  }
  div.speech.right {
    box-shadow: -2px 2px 5px #CCC;
    margin-right: 10px;
    width: 75%;
    float: right;
    background: -webkit-gradient( linear, 50% 0%, 50% 100%, from(#e4ffa7), color-stop(0.1, #bced50), color-stop(0.4, #aed943), color-stop(0.8, #a7d143), to(#99BF40) );
  }
  div.speech.right:before {
    content: '';
    position: absolute;
    width: 0;
    height: 0;
    top: 9px;
    bottom: auto;
    left: auto;
    right: -10px;
    border-width: 9px 0 9px 10px;
    border-color: transparent #989898;
  }
  div.speech.right:after {

    left: auto;
    right: -8px;
    border-width: 8px 0 8px 9px;
    border-color: transparent #bced50;
  }
  div.speech.left {
    box-shadow: 2px 2px 2px #CCCCCC;
    margin-left: 10px;
    width: 75%;
    float: left;
    background: -webkit-gradient( linear, 50% 0%, 50% 100%, from(#ffffff), color-stop(0.1, #eae8e8), color-stop(0.4, #E3E3E3), color-stop(0.8, #DFDFDF), to(#D9D9D9) );
  }
  div.speech.left:before {
    content: '';
    position: absolute;
    width: 0;
    height: 0;
    top: 9px;
    bottom: auto;
    left: -10px;
    border-width: 9px 10px 9px 0;
    border-color: transparent #989898;
  }
  div.speech.left:after {

    position: absolute;
    width: 0;
    height: 0;
    top: 10px;
    bottom: auto;
    left: -8px;
    border-width: 8px 9px 8px 0;
    border-color: transparent #eae8e8;
  }
  .leftimg {
    float: left;
    margin-top: 10px;
  }
  .rightimg {
    float: right;
    margin-top: 10px;
  }
  .leftd {
    clear: both;
    float: left;
    background: url(../img/ueser3.jpg) 0px 10px no-repeat;
    padding-left: 40px;
  }
  .rightd {
    clear: both;
    float: right;
    background: url(../img/ueser3.jpg) right 10px no-repeat;
    padding-right: 40px;
  }
  .clear {
    clear: both;
  }

HTML:

<div class="leftd">
<div class="speech left"> 你在吗？ </div>
</div>
