webrtc通过websocket客户端/服务器连接问题

不知道是否有人知道我在这里做错了什么：

我一直在关注：http://blog.felixhagspiel.de/index.php/posts/create-your-own-videochat-application-with-html-and-javascript

正如所解释的，该指南运行得非常好，我已经通过nodejs进行了测试，一切都非常好。

我现在正在尝试将示例移植到groovy中。在grails插件中并遇到一些问题。

所以我现在的处境是：对不起，实际代码的状态让我有一段时间头撞在砖墙上：）

所有者/服务器创建房间-精细

客户端出现并发送报价（收到报价，但客户端上的websocket断开连接）

服务器/所有者收到报价，但在尝试发送回复时-由于客户端断开连接，因此不会发送任何回复。。。。

这是websocket发送到解析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)
                }
            }
        }
    }
}

现在这就是浏览器上发生的情况：

---服务器：

首先在服务器上，我们登录到local.ip和remote.ip所在的位置，比如192.168.1.6，所以在客户端和服务器上都使用相同的ip，以确保其所有部分都属于相同的连接

http://local.ip.address:8080/testwschat/wsChat/

这为我们提供了一个聊天用户，我们以ff的身份登录

然后手动访问webrtc发送器

http://local.ip.address:8080/testwschat/wsChat/webrtcsend?user=ff

---在客户端：

我们首先登录服务器http://remote.ip.address:8080/testwschat/wsChat/

这为我们提供了一个聊天用户，我们在上以cc登录

然后手动访问webrtc接收器

根据上面套接字代码中的printlns，实际的后端websocket日志可以在这里看到：

https://gist.github.com/vahidhedayati/6dbd74a1c4a87d373c05

这次又有一些日志是通过网页来控制台sendServer值的，websocket似乎没有接收到icecandidate json。因为后端没有这方面的日志。。也许它的缓冲区有关。。
