Close specific WebSocket API Gateway connection. #10

Closed JoseRolles closed 5 years ago

JoseRolles commented 5 years ago

How do we close a specific WebSocket API Gateway client connection from the server side?

JoseRolles commented 5 years ago

Documentation at the following link says it is possible to close a connection from the backend by using @connections endpoint. It points to another documentation page which mentions nothing about closing a connection from the backend: https://docs.aws.amazon.com/apigateway/latest/developerguide/apigateway-websocket-api-route-keys-connect-disconnect.html

Also, I checked the JavaScript SDK reference and the only method is postToConnection without any mention of disconnecting the connectionId. https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/ApiGatewayManagementApi.html

@JoseRolles using @connections, DELETE to it should disconnect the client.

Perhaps the documentation could be updated so that people don't need to search github issues for answers?

Use DeleteConnectionCommand - https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/clients/client-apigatewaymanagementapi/classes/deleteconnectioncommand.html
