1.tomcat版本：apache-tomcat-7.0.32 2.如果你想實現(xiàn)WebSocket必須得用Tomcat7及以上版本，并且引入：catalina.jar，tomcat-coyote.jar兩個JAR包， 部署到Tomcat7之后得要去webapps/應(yīng)用下面去刪除這兩個AR包否則無法啟動 3.var mediaConstraints = { 'has_audio' : true, 'has_video' : true };這個變量在瀏覽器里報錯，替換成下面的寫法 var mediaConstraints = { "mandatory": { "OfferToReceiveAudio": true, "OfferToReceiveVideo": true } }; 4.把stream.videoTracks和stream.audioTracks都換成get*****Tracks()，注意首字母大寫。 5.pc.createAnswer(setLocalAndSendMessage, null, mediaConstraints); pc.createOffer(setLocalAndSendMessage, null, mediaConstraints); 以上兩行中的null替換成存在的回調(diào)函數(shù)，新建回調(diào)函數(shù) function setRemoteAndSendMessage(sessionDescription){ pc.setRemoteDescription(sessionDescription); }
