融云2.0的官方文档地址:http://docs.apicloud.com/端API/开放SDK/rongCloud2
项目需要IM模块,最后还是选择了融云.在iOS原生开发中,融云sdk集成了聊天界面,给开发者提供了很大的便利,但是在apicloud平台上,由于开发者应用IM的场景各异,需求不统一,所以官方没有将聊天界面集成到模块中.
因此我选择了AUI这套专门为apicloud提供的前端开发框架进行IM界面的搭建.AUI官方地址:http://www.auicss.com.
这套框架集成了很多手机端的UI,效果不错,而且还在不断的更新中,大家不妨尝试一下.我用过其中的几个,总体感觉还是不错的!
接下来,就具体的说一说RongYun集成的步骤了(本文会不断的更新,若发现不妥之处和需要改进的地方,可以给我留言,谢谢!)
在集成融云2.0之前,首先要到融云官网上进行注册,然后添加应用信息,并且生成两个测试用的targetId并记录下对应的token(这种方法仅为测试使用) 融云的官网:http://www.rongcloud.cn
之后在API调试里面 生成userID对应的token,这些信息在初始化融云时会用到,
之后再次生成一个userID,并记录对应的token.这样,就相当于建立了两个用户,用户A和用户B,,之后便可实现用户A与用户B之间的通信了.
上述内容准备完之后,就要在自己的apicloud应用中添加融云2.0模块了. apicloud中的融云集成之前的准备在此略过,可以参照官方文档.
在详细的介绍之前,先要说一说这个聊天界面使用的框架和模板.
1.doT.js (不熟悉的小伙伴可以参照这篇博客: http://www.cnblogs.com/kuikui/p/3505768.html)
2.AUI 前端UI框架(地址在上面给过了,很实用,小伙伴们可以看一看).
3.UIChatBox, 文档地址: http://docs.apicloud.com/端API/界面布局/UIChatBox#m11
好了,有了这几个,就可以轻松的完成一个简单的聊天界面的集成了!
首先要在config文件里填入一下代码
<feature name="rongCloud2">
<param name="appKey" value="这里填写在融云官网自己app对应的key" />
</feature><span style="font-size:14px;">apiready = function () {

rong.init(function (ret, err) {
if (ret.status == 'error') {
api.toast({msg: err.code});
} else {
api.toast({msg: "success"});
//链接到RongY
rong.connect({
token: '自己的token'
},
function (ret, err) {
// alert(JSON.stringify(ret));
if (ret.status == 'success') {
// api.toast({msg: ret.result.userId});
isConnetced = true;
// alert(isConnetced);
//实时监听收到的消息

});
}
});

// api.toast({ msg: err.code });
}
}
);
}
</span>上面就是我刚才发送的一连串语音消息了.
3.4 消息的接收
消息的接收,要用到 rong.setOnReceiveMessageListener这个方法.也就是这个方法会监听你收到的消息.具体代码如下
var rong = api.require('rongCloud2'); rong.setOnReceiveMessageListener(function (ret, err) { // alert(JSON.stringify(ret)); var tag; var para; if (ret.result.message.objectName == "RC:TxtMsg") { tag = "TxtMsg"; } else if (ret.result.message.objectName == "RC:ImgMsg") { tag = "ImgMsg"; } else if (ret.result.message.objectName == "RC:VcMsg") { tag = "VcMsg"; } else if (ret.result.message.objectName == "RC:LBSMsg") { tag = "LBSMsg"; } para = { firstSendType: "aui-chat-receiver", secondSendType: "aui-chat-receiver-avatar", thirdSendType: "aui-chat-receiver-cont", fourthSendType: "aui-chat-left-triangle", content: ret.result.message.content, tag: tag, receivedTime: getTrueTime(ret.result.message.receivedTime), messageDirection: "RECEIVE" }; if (!timeTag) { para.receivedTime = ""; } msgObj.push(para); var interText = doT.template($("#message-content-template").text()); $("#message-content2").html(interText(msgObj)); $("img.lazy").lazyload(); document.getElementsByTagName('BODY')[0].scrollTop = document.getElementsByTagName('BODY')[0].scrollHeight; //时间戳状态 timeTag = false; });
上面就是三条通过iPhone模拟器发送的消息,一条语音消息,一条图片消息,一天文字消息.
3.4 获取历史消息
获取历史消息也用对应的方法.而且这些消息是存在本地的,所以获取很方便
//获取最近聊天信息
function getRecentConverMsg() {
// alert(num);
var rong = api.require('rongCloud2');
//先获取之前的聊天记录
rong.getHistoryMessages({
conversationType: 'PRIVATE',
targetId: '13644978865',
oldestMessageId: -1,
count: 500
}, function (ret, err) {
// api.refreshHeaderLoadDone();
var arr = [];
arr = ret.result;
// alert(JSON.stringify(arr));
//记录最早的时间戳
$api.setStorage('time', arr[arr.length - 1].receivedTime);
for (var i = arr.length - 1; i >= 0; i--) {
if (arr[i].messageDirection == "SEND") {
arr[i].firstSendType = "aui-chat-sender";
arr[i].secondSendType = "aui-chat-sender-avatar";
arr[i].thirdSendType = "aui-chat-sender-cont";
arr[i].fourthSendType = "aui-chat-right-triangle";
} else {
arr[i].firstSendType = "aui-chat-receiver";
arr[i].secondSendType = "aui-chat-receiver-avatar";
arr[i].thirdSendType = "aui-chat-receiver-cont";
arr[i].fourthSendType = "aui-chat-left-triangle";
}
if (arr[i].objectName == "RC:TxtMsg") {
arr[i].tag = "TxtMsg";
} else if (arr[i].objectName == "RC:ImgMsg") {
arr[i].tag = "ImgMsg";
} else if (arr[i].objectName == "RC:VcMsg") {
arr[i].tag = "VcMsg";
} else if (arr[i].objectName == "RC:LBSMsg") {
}
//如果时间间隔大于五分钟 加上时间戳
if (arr[i].receivedTime - $api.getStorage("time") >= 180000) {
// alert("yes");
$api.setStorage('time', arr[i].receivedTime);
arr[i].receivedTime = getTrueTime(arr[i].receivedTime);
arr[i].sentTime = getTrueTime(arr[i].sentTime);
} else {
arr[i].receivedTime = "";
arr[i].sentTime = "";
}
msgObj.push(arr[i]);
}
var interText = doT.template($("#message-content-template").text());
$("#message-content2").prepend(interText(msgObj));
$("img.lazy").lazyload();
document.getElementsByTagName('BODY')[0].scrollTop = document.getElementsByTagName('BODY')[0].scrollHeight;
});
}
这样,我可以获取到之前3.31的聊天记录.
到这里,最基本的功能介绍完了,后续的功能还有很多,比如图片的查看,保存图片到本地,语音的播放等等,都是小问题了,这些代码就不放上来了.
本文会不断更新,欢希望大家提出更多的意见,一起进步!我的微信656593047,可以加我一起交流!!
