建立连接的日志：
第一步：创建本机的PeerConnection
Created local peer connection object localConnection
main.js:50 Created send data channel
main.js:66 Created remote peer connection object remoteConnection
第而不：获得本机的媒体信息sdp，为了向对方发offer
main.js:113 Offer from localConnection

----------媒体信息交换完成，走完协商第一步，开始交换网络信息--------------
第四步：从ice服务器获得公网ip，发送给对端peer，
main.js:140 remotePeerConnection ICE candidate: candidate:1613033416 1 udp 2113937151 c83d25f9-2ef3-43af-b124-18e2be66ce56.local 54362 typ host generation 0 ufrag bx6n network-cost 999
