websocket

问题 I have an issue that I cannot solve. I implemented a node js WebSockets server on an openshift cartridge using socket.io or WebSockets node js libraries. With any of them the result is the same. With a node js client running on the same openshift platform everything works ok. When the client is moved on my local pc the client connects and suddenly disconnects giving a 1011 internal server error. I tried using other well known clients like the echo service on WebSockets.Org or jsfiddle but the

问题 I am building an AngularJS application and using the Paho JavaScript client to connect to an MQTT broker (test.mosquitto.org) via web sockets. This works just fine. I wanted to connect to the MQTT broker via direct MQTT (for sake of completeness to support brokers that do not have websockets enabled). Since the Paho client does not support direct MQTT, I tried the browserified version of mqtt.js (browserMqtt.js). Here's the main lines from my code: //var options = { host: "test.mosquitto.org"

问题 I am gonna develop a real time game for andriod/ios and i need a server which transmit data with client real time. Can i use socket.io with Spring boot? Or if the answer is no , using websockets with Spring boot is the solution? 回答1: Probably this library could be useful for your needs. By the way Socket.io will try to use WebSocket API. In case if it's not supported by the browser then Socket.io will gracefully fallback to something else. 回答2: The original Socket.IO server is designed to be
