Ask a question: about WEBRTC communication

In the next is WEBRTC development novice, at present encountered a problem, turned over to have not understood. Maybe English is not good, look at the document to see blindfolded, so has not found a solution.

Development environment:

node. JS Server built

I'm using Socket.io to do communications now.

Development Purpose:

A classmate to B students to initiate a request, B received after the two sides live video.

If there is a clear classmate trouble tell me ha, really trouble everyone O (∩_∩) o~~

Problem Description:

Currently in the two-person video demo, but on both sides of the signal exchange information problems. The console prints it out like this:

The code is as follows:

1   varServers =NULL;2 3   functionTrace (text) {4Console.log ((Performance.now ()/+). ToFixed (3) + ":" +text);5   }6 7 //Creating an Peerconnection instance8Localpeerconnection =Newrtcpeerconnection (servers);9Trace ("Created local Peer Connection object Localpeerconnection");Ten  ALocalpeerconnection.onicecandidate =function(evt) { -      -Socket.send (json.stringify ({"Candidate": Evt.candidate}); the  -Trace ("Local ICE candidate: \ n" +evt.candidate.candidate); -  -   } + -Localpeerconnection.onaddstream =function(evt) { +REMOTEVIDEO.SRC =Url.createobjecturl (evt.stream); ATrace ("Add remote stream to other peer") at   }; -  - Localpeerconnection.addstream (localstream); -Trace ("Added Localstream to Localpeerconnection"); -  -   if(iscaller) { in Localpeerconnection.createoffer (gotdescription, handleError); -  to   } +   Else{ - Localpeerconnection.createanswer (localpeerconnection.remotedescription, gotdescription); the   } *  $ }Panax Notoginseng  - functiongotdescription (evt) { the  + localpeerconnection.setlocaldescription (evt); ASocket.send (json.stringify ({"SDP": evt}); the } +  -Socket.on (' Pushmessagedone ',function(evt) { $  $     if(!localpeerconnection) { -Console.log (1); -Callfalse); the     } - Wuyi     varSignal =Json.parse (evt); the  -     if(SIGNAL.SDP) { Wu  -Localpeerconnection.setremotedescription (Newrtcsessiondescription (SIGNAL.SDP)); About}Else { $  -Localpeerconnection.addicecandidate (Newrtcicecandidate (signal.candidate)); -       } - }); A  +  the functionHandleError () {}
