websocket

问题 Our application is entirely built on websockets. We don't do any HTTP request-reply. However, we are stuck with file download. If i receive file content via websockets can I wrote to local folder on user computer ? If it makes a difference, we are only supporting Chrome so not issue if it doesn't work on other browsers. Also, I know i can do this via HTTP. Trying to avoid it and stick to websockets since thats how the entire app is. Thanks a lot in advance! 回答1: The solution depends on size

问题 I have an exisiting Java application which is exposing REST services. I want to add a new feature in the same application to handle web socket requests (using netty) along with the exisiting REST services. How can I do that without changing my REST services? 回答1: There are two ways to do this without changing your REST service: I would suggest you setup a normal netty websocket server and run it parallel on another port (this can happen in the same application). A more complicated an

How to keep my Lamda function running forever? Thanks! Right now I'm running my crawler inside a Linux
