概述

metaRTC除了实现流媒体功能之外，信令功能支持为websocket，metaRTC新版本支持纯C版的websocket。

第三方类库

第三方类库使用的是纯C版的libwebsockets

libwebsockets: canonical libwebsockets.org websocket libraryhttps://gitee.com/commanderZY/libwebsockets

编程代码

初始化代码

//接收数据回调函数
int g_websocket_receive(void* context,YangSample* data){
    ......
    return Yang_Ok;
}    


YangWebsocket websock=(YangWebsocket*)calloc(sizeof(YangWebsocket),1);
YangWebsocketCallback callback;
callback.context=this;
callback.receive=g_websocket_receive;
yang_create_websocket(websock,&callback);

连接websocket服务器

 char* url=(char*)"ws://127.0.0.1:8082/test";
 websock->connectServer(websock->context,url);
//发送数据
sprintf((char*)test,"this is %d test!",testcount++);
websock->sendData(websock->context,(uint8_t*)test,strlen(test));

删除代码

yang_destroy_websocket(websock);
yang_free(websock);
