3. createWebRtcTransport
<h5>简要描述</h5>
<ul>
<li>创建数据传输通道
mediasoup-client和libmediasoupclient都需要单独的WebRTC-“transports"进行发送和接收。
通常，客户端应用程序甚至在希望发送或接收媒体之前都会预先创建那些"transports”。
For sending media: 发送媒体</li>
</ul>
<p>创建数据通道流程在创建mediasoup::Device设备之后进行。
通常会创建2条数据通道，区别只是producing不同，一条生产数据一条不生产数据</p>
<h5>请求方式</h5>
<ul>
<li>Websocket.Send </li>
