曾经我尝试做一个类似~~钉钉~~的开源产品。但是在找投资的时候,被告知类似的产品很多,产品并没有太多的意义。所以它在硬盘里又躺了快1年吧,最后我想还是放出来吧。 这是一款IM 产品,它以网页版的形式提供服务,支持手机端 PC端。它的功能包括 直接语音留言, 视频聊天,音频聊天,文字聊天,加好友等基本功能。没错,是利用网页直接进行视频聊天,语音聊天。在webrtc 如此使用广泛的情况下,做到这点很容易。 说说效果,在局域网里,比如在公司内部,我觉得你可以获得不亚于QQ 微信的使用体验。视频聊天都会非常正常,效果也不错。如果是互联网上,你文字和语音留言都不成问题,如果要视频,你需要专门提供一个stun服务器才有可能。stun的速度决定了你的效果。坦白地说,利用网页形式 直接进行视频聊天的条件并不成熟。但是5G时代,我相信这样的应用会更加容易实现 我搭建了一个演示网站,可以直接使用 https://www.meetyoucn.com ![网站首页](https://raw.githubusercontent.com/xiaojiaqi/Venus/master/manual/meetyou.png) 效果大概这样! ![Watch the video](https://raw.githubusercontent.com/xiaojiaqi/Venus/master/manual/Video.jpg)](http://www.iqiyi.com/w_19s8wf4dp5.html) 部署 1. 如果 我在Internet 上部署,我需要做什么? 首先你需要准备SSL证书。然后将证书分别改名为cert.pem 和 key.pem。覆盖项目里原有的证书。 其次,你需要安装一个redis 服务器作为数据库。 下载完源码: 在本地看大概这样 ![Image text](https://raw.githubusercontent.com/xiaojiaqi/Venus/master/manual/5.png) ​ 代码的位置在 /webroot/html/js/domain.js 修改代码里的配置 ![修改代码](https://raw.githubusercontent.com/xiaojiaqi/Venus/master/manual/6.png) 然后分别重新启动 程序即可。 注意 启动离线语音消息服务器的时候,需要 修改域名部分。 启动的样子大概这样, 启动网站 ![运行网站](https://raw.githubusercontent.com/xiaojiaqi/Venus/master/manual/1.png) 启动 信令服务器 ![运行信令](https://raw.githubusercontent.com/xiaojiaqi/Venus/master/manual/2.png) 启动IM服务器 这个需要指定redis服务器的地址 ![运行IM](https://raw.githubusercontent.com/xiaojiaqi/Venus/master/manual/3.png) 启动离线语音消息服务器, 注意 这个需要指定完整的域名 ![运行离线语言](https://raw.githubusercontent.com/xiaojiaqi/Venus/master/manual/4-1.png) ​ 比如你的域名是 www.aaa.com 那么你启动离线语音消息服务器的命令就是 ./upload -hostname=https://www.aaa.com 注意必须是https://www.aaa.com 不是http://www.aaa.com 注意 在Internet 上进行视频通信,需要安装stun,否则视频大概率是会失败的。 比如你和对方在不同地方使用手机,服务器在Internet上,直接文字聊天,语音留言都没有问题,但是你们直接视频聊天大概率会失败。 如果你和对方在同一局域网内,使用的服务器在Internet上,那么无论文字聊天,语音留言,直接视频是没有问题的。 ​ 2. 如果我有自己的域名和证书, 我想在局域网里部署,我需要做什么? 同Internet 部署,没有任何区别 3. 如果你没有自己域名和证书,但是也想试试局域网部署。 首先,确认你会安装服务器程序的IP, 如果 它们的Ip 是如下IP 里的一个,那么你可以用这个程序直接安装。 ![Image text](https://raw.githubusercontent.com/xiaojiaqi/Venus/master/manual/dns.png) ​ 比如我想安装到的服务地址是 192.168.0.1 那么我可以用www01.meetyoucn.com 作为你的局域网里的域名。 ​ 第一步 修改源码 ​ 代码的位置在 /webroot/html/js/domain.js 修改代码里的配置 ![修改代码](https://raw.githubusercontent.com/xiaojiaqi/Venus/master/manual/6.png) ​ 将域名修改成 www01.meetyoucn.com 然后分别重新启动 程序即可。 注意 启动离线语音消息服务器的时候,需要 修改域名部分。 启动的样子大概这样, 启动网站 ![运行网站](https://raw.githubusercontent.com/xiaojiaqi/Venus/master/manual/1.png) 启动 语音聊天的信令服务器 ![运行信令](https://raw.githubusercontent.com/xiaojiaqi/Venus/master/manual/2.png) 启动IM服务器 这个需要指定redis服务器的地址 ![运行IM](https://raw.githubusercontent.com/xiaojiaqi/Venus/master/manual/3.png) 启动离线语音消息服务器, 注意 这个需要指定完整的域名 启动命令将改成 ./upload -hostname=https://www01.meetyoucn.com ![运行离线语音](https://raw.githubusercontent.com/xiaojiaqi/Venus/master/manual/4-1.png) 然后你使用 电脑 手机 ipad 打开 https://www01.meetyoucn.com 就可以注册,运行产品了。 浏览器版本要求 | | 文字聊天 | 视频聊天 | 操作系统 | | :---------: | ----- | --------------- | ---- | | PC | 所有浏览器 | Firefox, Chrome | 无要求 | | Ipad/Iphone | 所有浏览器 | Safari | 12.0 | | Android | 所有浏览器 | Chrome | 无要求 | 服务器一共有5个。我发现虽然开源过代码,但是我发现大家并没什么兴趣,看来一个可用的产品才是最重要了。 - 第一个 是 网页部分,这个部分是基于一个Layim的产品构建的。我已经购买了源码,你可以放心在上面继续开源使用。 - 第二个 是一个Web服务器, 这个你完全可以用一个nginx服务代理。 - 第三个 是语音留言服务器, 当你进行语音留言的时候,它会帮你将数据存储在web服务器上。 - 第四个 是信令服务器, 主要用于视频聊天时管理双方的信令交互。 - 第五个 是IM服务器,主要负责好友关系处理,聊天这样的服务。 如何使用docker 运行? docker 的使用很简单。 使用 docker push xiaojiaqi/venus:0.1.0 下载镜像! https://cloud.docker.com/repository/registry-1.docker.io/xiaojiaqi/venus 3 种情况 第一种, 我就是用镜像测试一下 首先,假设你没有域名,那么你需要找一个 上图里的 ip,作为你的服务器。 比如你本地服务器 ip 是 192.168.2.2 那么 www22.meetyoucn.com 就是你可以用的域名 运行一下命令 就 ok 了 sudo docker run --env WEBHOST=www22.meetyoucn.com -p 80:80 -p 443:443 -p 8888:8888 -p 8090:8090 -p 8091:8091 -d xiaojiaqi/venus:0.1.0 这种玩法的缺点在于,容器重启 资料就没了。 第二种情况, 我本地有一个 redis 服务器,我想把数据保留下来 假设我的 redis 是 192.168.1.1 我的本地服务器还是 192.168.2.2, 那么域名就仍然是 www22.meetyoucn.com 运行以下命令 sudo docker run --env WEBHOST=www22.meetyoucn.com --env REDIS=192.168.1.1:6379 -p 80:80 -p 443:443 -p 8888:8888 -p 8090:8090 -p 8091:8091 -d xiaojiaqi/venus:0.1.0 第三种情况, 我有一个自己的证书, 我想用自己的域名 那么你需要把 cert.pem key.pem 两个挂载进系统 差不多就是这样 sudo docker run -v /local/cert.pem:/app/cert.pem -v /local/key.pem:/app/key.pem --env WEBHOST=www.myhost.com --env REDIS=192.168.2.30:6379 -p 80:80 -p 443:443 -p 8888:8888 -p 8090:8090 -p 8091:8091 -d xiaojiaqi/venus:0.1.0 源码的话,看大家反应吧,如果星多就逐步发布吧。 有任何问题 都可以邮件 xiaojiaqi.cn#gmail.com
