通过websocket客户端/服务器连接问题webrtc
不知道是否有人有什么我在做什么错误在这里：
我一直在： http : //blog.felixhagspiel.de/index.php/posts/create-your-own-videochat-application-with-html-and-javascript
该指南工作得很好，我已经通过nodejs进行了testing，所有工作都非常好。
我现在试图把这个例子转换成groovy。 在一个Grails插件中，并遇到一些问题。
所以这就是我所在的地方：打扰一下我的头撞砖墙的实际代码的状态:)
所有者/服务器创build空间 – 很好
客户来了，发送报价（收到的报价，但客户端断开WebSocket）
服务器/所有者收到报价，但试图发送回答 – 因为客户端断开连接没有发送回….

这是websocket发送到parsing操作的扩展类的地方：

呼叫：

private void jsonmessageUser(Session userSession,String msg) { userSession.getBasicRemote().sendText(msg as String) } private void jsonmessageOther(Session userSession,String msg) { Iterator<Session> iterator=camsessions?.iterator() if (iterator) { while (iterator?.hasNext()) { def crec=iterator?.next() if (crec.isOpen()) { def cuser=crec.getUserProperties().get("camuser").toString() def cmuser=crec.getUserProperties().get("camusername").toString() println "OM ACTIVE USER : ------- ${cuser}" if (!cuser.toString().endsWith(cmuser)) { println "----OTHER ||| ${cmuser} :: ${msg}" crec.getBasicRemote().sendText(msg as String) } } } } } private void jsonmessageOwner(Session userSession,String msg) { Iterator<Session> iterator=camsessions?.iterator() if (iterator) { while (iterator?.hasNext()) { def crec=iterator?.next() if (crec.isOpen()) { def cuser=crec.getUserProperties().get("camuser").toString() def cmuser=crec.getUserProperties().get("camusername").toString() if (cuser.toString().endsWith(cmuser)) { println "----OWNER ||| ${cuser} :: ${msg}" crec.getBasicRemote().sendText(msg as String) } } } } } 现在这是浏览器上发生的事情：
—服务器：
首先在服务器上我们loginlocal.ip和remote.ip可以说192.168.1.6所以客户端和服务器都击中这个相同的IP，以确保它的所有部分相同的连接
HTTP：//local.ip.address：8080 / testwschat / wsChat /
这给了我们一个聊天用户，我们以上面的fflogin
然后手动访问webrtc发件人
HTTP：//local.ip.address：8080 / testwschat / wsChat / webrtcsend用户= FF

—在客户端：
首先在服务器上，我们login到http：//remote.ip.address：8080 / testwschat / wsChat /
这给了我们一个聊天用户，我们以上面的cclogin
然后手动访问webrtc接收器
HTTP：//remote.ip.address：8080 / testwschat / wsChat / webrtcrec用户= FF

在上面的套接字代码中，根据printlns的实际后端websocket日志可以在这里看到：
https://gist.github.com/vahidhedayati/6dbd74a1c4a87d373c05
这次通过日志logging来控制sendServer的值通过网页，这似乎icecandidate json没有被websocket接收。 因为在后端没有这个日志..也许它的缓冲相关..
https://gist.github.com/vahidhedayati/918b731788118de348d0 – 服务器或所有者浏览器日志
https://gist.github.com/vahidhedayati/a51796f3dcbb14088a31 – 客户端/其他用户浏览器日志。
那么我认为我最近的调查帮助我回答了我自己的问题，那就是缓冲区大小。
所以，如果你在Java / Groovy编码，并想与webrtc交互。 你可能会遇到这个问题。 解决的办法是增加你的
session.setMaxTextMessageBufferSize(1000000)
当用户打开websocket
@OnOpen public void whenOpening(Session userSession,EndpointConfig c,@PathParam("user") String user,@PathParam("viewer") String viewer) { if (loggedIn(user)) { userSession.setMaxBinaryMessageBufferSize(1024*512) userSession.setMaxTextMessageBufferSize(1000000) //userSession.setmaxMessageSize(-1L) if (viewer.equals(user)) { userSession.getUserProperties().put("camuser", user+":"+user); }else{ userSession.getUserProperties().put("camuser", user+":"+viewer); } if (!camLoggedIn(user)) { userSession.getUserProperties().put("camusername", user); camsessions.add(userSession) } }else{ log.info "could not find chat user ! ${user}" } }
