过时
This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

非标
此特征是非标准的，且不在标准轨道中。不要在面向 Web 的生产站点中使用它：它不适用于每个用户。实现之间可能存在大的不兼容性，且行为将来可能改变。

The deprecated (and never part of the official specification) read-only RTCDataChannel property stream returns an ID number (between 0 and 65,535) which uniquely identifies the RTCDataChannel . This ID is set at the time the data channel is created, either by the user agent (if RTCDataChannel.negotiated is false ) or by the site or app script (if negotiated is true ).

This property has been replaced with the RTCDataChannel.id property. If you have code that uses stream , you will need to update, since browsers have begun to remove support for stream .

句法

var stream = aDataChannel.stream;
					

值

An unsigned short value (that is, an integer between 0 and 65,535) which uniquely identifies the data channel.

范例

var dataChannel = pc.createDataChannel("SampleChannel");

console.log("Data channel stream ID: " + dataChannel.stream);
