Overview

WCS integrates with the back-end server using REST / HTTP calls or REST Methods as we call them.

Therefore, you provide the WCS server with the script API, and WCS sends data on connections, calls, video streams etc. to the API.

 


 REST methods can be used to:

  • Authenticate connections to the server by token or by password
  • Receive real-time information about connects, disconnects, started and ended streams, calls and so on.
  • Redefine data received from the client. For example, you can rename a stream or hide its real name or redirect a call.
  • Implement custom signaling with Websockets transmission of data. For example, send a text message in the chat to all connected clients.

REST methods should be implemented as simple HTTP / HTTPS scripts that work in pair with JSON in the body of an HTTP request and return JSON in the HTTP body of responses.

Disable REST hooks

REST hook sending is enabled by default. To disable it, the following parameter must be set in flashphoner.properties file

disable_rest_requests=true

Backend server response delays handling

Backend server response to WCS requests delays are possible under high load. Maximum di=uration of such delays can be controlled with the following parameter in flashphoner.properties file

rest_request_timeout=15

By default, maximum backend server response delay duration set to 15 seconds. If backend response is not received during this time, the exception will be printed to server logs

09:05:17,012 ERROR           RestClient - API-ASYNC-pool-12-thread-2 Got exception in REST 
java.net.SocketTimeoutException: Read timed out

The error will be handled as set in restClientConfig.

It is stringly recommended to set maximum backend server response delay duration from 1 to 10 seconds. The value

rest_request_timeout=0

fully disables delay control.
