Question

想知道是否有人对我在这里做错了什么有任何想法：

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

该指南的解释非常好，我已经通过nodejs进行了测试，并且一切正常。

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

所以这就是我所处的位置：原谅实际代码的状态让我在砖墙上碰了一会儿：）

所有者/服务器创建空间 - 精细

客户端出现并发送报价（收到报价但客户断开连接的websocket）

服务器/所有者收到要约，但在尝试发送回答时 - 由于客户端已断开连接，因此无法发回任何内容....

https://github.com/vahidhedayati/playground/blob/master/grails-wschat-plugin/src/groovy/grails/plugin/wschat/WsCamEndpoint.groovy#L72

这是websocket发送到解析操作的扩展类的地方：

https://github.com/vahidhedayati/playground/blob/master/grails-wschat-plugin/src/groovy/grails/plugin/wschat/ChatUtils.groovy#L244

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登录到local.ip和remote.ip就是192.168.1.6，所以在客户端和服务器上点击这个相同的ip以确保它的所有部分都是相同的连接

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

这为我们提供了一个我们以上面的ff登录的聊天用户

然后手动访问webrtc发件人

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

---在客户端：

首先在服务器上登录 http://remote.ip.address:8080/testwschat/wsChat/

这为我们提供了一个我们以上面的cc登录的聊天用户

然后手动访问webrtc接收器

http://remote.ip.address:8080/testwschat/wsChat/webrtcrec?user=ff

上面的套接字代码中的printlns的实际后端websocket日志可以在这里看到：

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

这次通过登录到通过网页控制sendServer值来记录更多日志，似乎websocket没有收到icecandidate json。因为在后端没有这个日志..也许它的缓冲区相关..

Answer 1

好吧，伙计们，我认为我的上一次调查帮助我回答了我自己的问题，那就是缓冲区大小。

因此，如果您使用Java / Groovy进行编码并希望与webrtc进行交互。你可能会遇到这个问题。修复是增加你的

session.setMaxTextMessageBufferSize(1000000)

当用户打开websocket

时

@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}"
        }
    }

webrtc通过websocket客户端/服务器连接问题
