一、连接地址
ws://192.168.0.131:8888/roomId/:roomId
下面示例 roomId = fm2
连接成功授权返回数据

{"type":"authorization","data":{"peerId":"df9bf510-f4ce-4959-a5ab-d8e72fc04a7f","roomId":"fm2"}}

二、创建producer流程
1、join 加入房间

{
    "type": "join",
    "data": {
        "peerId": "df9bf510-f4ce-4959-a5ab-d8e72fc04a7f",
        "roomId": "fm2"
    }
}

2、createTransport 创建传输通道

{
    "type": "createTransport",
    "data": {
        "isConsumer": false,
        "peerId": "df9bf510-f4ce-4959-a5ab-d8e72fc04a7f",
        "roomId": "fm2"
    }
}

3、connectTransport 开始连接通道

{
    "type": "connectWebRtcTransport",
    "data": {
        "transportId": "aee458cc-54bd-48c9-a0a9-d9b86f21c197",
        "dtlsParameters": {
            "role": "client",
            "fingerprints": [
                {
                    "algorithm": "sha-256",
                    "value": "7F:FD:11:53:CF:3E:B1:8F:AB:95:82:5E:C8:9B:81:3D:3A:7F:11:C2:BC:93:57:98:7C:1D:16:78:2F:FB:29:6E"
                }
            ]
        },
        "isConsumer": false,
        "peerId": "df9bf510-f4ce-4959-a5ab-d8e72fc04a7f",
        "roomId": "fm2"
    }
}

4、producer webrtc createOffer 成功之后，将数据提取发送给 mediasoup,数据开始传输

{
    "type": "producer",
    "data": {
        "transportId": "aee458cc-54bd-48c9-a0a9-d9b86f21c197",
        "kind": "video",
        "rtpParameters": {
            "codecs": [
                {
                    "mimeType": "video/VP8",
                    "payloadType": 96,
                    "clockRate": 90000,
                    "parameters": {},
                    "rtcpFeedback": [
                        {
                            "type": "goog-remb",
                            "parameter": ""
                        },
                        {
                            "type": "transport-cc",
                            "parameter": ""
                        },
                        {
                            "type": "ccm",
                            "parameter": "fir"
                        },
                        {
                            "type": "nack",
                            "parameter": ""
                        },
                        {
                            "type": "nack",
                            "parameter": "pli"
                        }
                    ]
                },
                {
                    "mimeType": "video/rtx",
                    "payloadType": 97,
