部分代码如下所示:

if (message.type === 'offer') {
    console.log("got offer");
    console.log(message);
    pc.setRemoteDescription(new SessionDescription(message));
    console.log(pc);
    createAnswer();
}
else if (message.type === 'answer') {
    console.log("got answer");
    console.log(message);
    pc.setRemoteDescription(new SessionDescription(message));
    console.log(pc);
}


Calee成功设置了远程描述,pc.remoteDescription已填写。但是,呼叫者...收到与被呼叫者相同的消息,但在pc.setRemoteDescription(new SessionDescription(message));变为pc.remoteDescription为空并且注意到发生之后。被叫方准备接收流,但被叫方卡住。

最佳答案

我认为问题是因为setRemoteDescription失败,或者在与createAnswer之间存在竞争条件,因此请将其添加到成功回调中,并且为了清楚起见,也添加错误回调...

就像是:

if (message.type === 'offer') {
    console.log("got offer");
    console.log(message);
    pc.setRemoteDescription(new SessionDescription(message), function(){
        console.log(pc);
        createAnswer();
    }, console.error.bind(console));
}
else if (message.type === 'answer') {
    console.log("got answer");
    console.log(message);
    pc.setRemoteDescription(new SessionDescription(message), console.log.bind(console, 'success'), console.error.bind(console));
}


如果支持Promise和ES6:

if (message.type === 'offer') {
    console.log("got offer");
    console.log(message);
    pc.setRemoteDescription(new SessionDescription(message))
      .then(() =>{
        console.log('success...', pc);
        createAnswer();
      }).catch(e => console.error(e));
}
else if (message.type === 'answer') {
    console.log("got answer");
    console.log(message);
    pc.setRemoteDescription(new SessionDescription(message))
      .then(() => console.log('success...', pc))
      .catch(e => console.error(e));
}
