RESTful API Path Rule for WSNManage
This document is about EIS RESTful API service of Wireless Sensor Manage (WSNManage). There are two major classes in WSNManage service one is "Connectiviy" another is "SenHub". Connectivity is wireless interfaces information in the EIS IoT Gateway solution. "SenHub" is short of sensor hub.

Socket.io
EIS socket.io Protocol
There are two methods ( 1. request / response, 2. auto push message to client ) to get information by Socket.io.
Request
Direction: Client -> Socket.io Server
Event: request
Format: {"n":"<Action>", "data":{obj}, "sessionId":<#>}
Action:
- service: To qurey what services provided by Socket.io server.
- subscribe: To subscribe service that you interested (ex:WSNManage). Server will auto push event and message after success to joint service.
- unsubscribe: To unsubscribe service if you don't want to interested it. Server will stop to push event and message to this client.
"data": data of request in JSON object.
"sessionId": Unique interger number of each request for distinguish. Server would response and fill the same sessionId.
Response
Direction: Server -> Client
Event: response
Format: {"status":<#>, "data":{obj}, "sessionId":<#>}
"status": Refer to HTTP Status Code ( 200 -> OK , 404 -> Not Found )
"data": data of reply information in JSON object
"sessionId": Server need reply the same sessionId with client's request.
Example of Action
service: Client query which event services provided by Socket.io Server
C->S <Request>: {"n":"service", "data":"", "sessionId":8954}
S-> C <Response>: {"status":200,"data":{"service":{ "e":[{"n":"WSNManage"},{"n":"SUSIManage"}]}},"sessionId":8954}
subscribe:Client subscibe in to join to receive which event Socket.io service
C->S <Request>: {"n":"subscribe", "data":"WSNManage", "sessionId":54774}
S-> C <Response>: {"status":200,"data":[{"event":"eConnectivity_Capability"},{"event":"eConnectivity_UpdateData"}, {"event":"eSenHub_Connected"},{"event":"eSenHub_Disconnect"},
{"event":"eSenHub_Capability"}, {"event":"eSenHub_UpdateData"}]"sessionId":8954}
unsubscribe: Clinet unsubscribe to leave which event Socket.io Service
C->S <Request>: {"n":"unsubscribe", "data":"WSNManage", "sessionId":6666}
S-> C <Response>: {"status":200,"sessionId":6666}
Message
Direction: Server -> Client
Event: message
Format: {"n":"<ServiceName>", "event":"<eventType>", "data":{obj})
"ServiceName": Service Name
"event": event type of this push message
"data": push data message in JSON object.
WebSocket Service
WebSocket is a computer communications protocol, providing full-duplex communication channels over a single TCP connection. The WebSocket protocol was standardized by the IETF as RFC 6455 in 2011, and the WebSocket API in Web IDL is being standardized by the W3C.
WebSocket is designed to be implemented in web browsers and web servers, but it can be used by any client or server application. The WebSocket Protocol is an independent TCP-based protocol. Its only relationship to HTTP is that its handshake is interpreted by HTTP servers as an Upgrade request.[1] The WebSocket protocol makes more interaction between a browser and a web server possible, facilitating the real-time data transfer from and to the server. This is made possible by providing a standardized way for the server to send content to the browser without being solicited by the client, and allowing for messages to be passed back and forth while keeping the connection open. In this way, a two-way (bi-directional) ongoing conversation can take place between a browser and the server. The communications are done over TCP port number 80, which is of benefit for those environments which block non-web Internet connections using a firewall. Similar two-way browser-server communications have been achieved in non-standardized ways using stopgap technologies such as Comet.
Websocket of WSNManage
Endpoint: ws://ServerIP:Port/WSNManage
Client request Server by this Endpoint to require "WSNManage" service. Server will auto push WSNManage event to client.
Please refer to "WSNManage evnent message" Events and data of WSNManage service.
