这是 实验性技术
检查 浏览器兼容性表格 要小心谨慎在生产中使用这之前。

The read-only property RTCPeerConnection.remoteDescription 返回 RTCSessionDescription describing the session (which includes configuration and media information) for the remote end of the connection. If this hasn't been set yet, this is null .

The returned value typically reflects a remote description which has been received over the signaling server (as either an offer or an answer) and then put into effect by your code calling RTCPeerConnection.setRemoteDescription() in response.

句法

 var sessionDescription = peerConnection.remoteDescription;
					

On a more fundamental level, the returned value is the value of RTCPeerConnection.pendingRemoteDescription if that property isn't null ; otherwise, the value of RTCPeerConnection.currentRemoteDescription is returned. See Pending and current descriptions in WebRTC connectivity for details on this algorithm and why it's used.

范例

This example looks at the remoteDescription and displays an alert containing the RTCSessionDescription 对象的 type and sdp 字段。

var pc = new RTCPeerConnection();
…
var sd = pc.remoteDescription;
if (sd) {
  alert("Remote session: type='" +
        sd.type + "'; sdp description='" +
        sd.sdp + "'");
}
else {
  alert("No remote session yet.");
}
