licode服务端总结

1.系统架构

2.nuve模块

(修改：https://blog.csdn.net/u012908515/article/details/53940787)

app.post(‘/rooms‘, roomsResource.createRoom);
app.get(‘/rooms‘, roomsResource.represent);

app.get(‘/rooms/:room‘, roomResource.represent);
app.put(‘/rooms/:room‘, roomResource.updateRoom);
app.patch(‘/rooms/:room‘, roomResource.patchRoom);
app.delete(‘/rooms/:room‘, roomResource.deleteRoom);

app.post(‘/rooms/:room/tokens‘, tokensResource.create);

app.post(‘/services‘, servicesResource.create);
app.get(‘/services‘, servicesResource.represent);

app.get(‘/services/:service‘, serviceResource.represent);
app.delete(‘/services/:service‘, serviceResource.deleteService);

app.get(‘/rooms/:room/users‘, usersResource.getList);

app.get(‘/rooms/:room/users/:user‘, userResource.getUser);
app.delete(‘/rooms/:room/users/:user‘, userResource.deleteUser);

2.1签名验证

app.get(‘*‘, nuveAuthenticator.authenticate);
app.post(‘*‘, nuveAuthenticator.authenticate);
app.put(‘*‘, nuveAuthenticator.authenticate);
app.patch(‘*‘, nuveAuthenticator.authenticate);
app.delete(‘*‘, nuveAuthenticator.authenticate);

每一次客户端请求都会进行签名验证。

2.2cloudHandle.js

cloudHandler提供了nuve对EC的调用：获取房间中的所有用户，删除房间，删除指定用户；以及EC对nuve的调用：删除token，EC的添加、状态更新，删除以及保活。

调用方法通过RPCMQ实现，他们共同维护了两个队列，队列A用来传递调用消息，Nuve发布调用消息后，并且会维护一个调用方法和回调函数的字典；EC从队列A中获取调用消息后执行调用方法，并将结果消息push进队列B；Nuve从队列B中获取调用结果消息，并从字典中得到回调函数并执行callback，删除对应字典值。

2.3服务、房间、用户管理
