问题 I need to implement long polling in my application to retrieve the events. But I have no idea how to do it. I know the concept of long polling, i.e to leave the connection open, until an event occurs. But how do I do implement this in my project. If you could give me a simple long polling example of client side and the views i guess, I would really appreciate. Thank you! 回答1: very simple example: import time def long_polling_view(request): for i in range(30): #e.g. reopen connection every 30

Cometd javascript client doesn't subscribe to broadcast channel

孤者浪人 提交于 2020-01-06 23:44:28
问题 It seems that the javascript client cannot subscribe to the broadcast channel or receive the message from it. Below is the spring-cometd service code that broadcast the message on the notification channel after receiving message from external event. The java-cometd client can receive the broadcast messages sucessfuly. Even the javascript client can publish and subscribe the messages on service channels but not on broadcast channel. The subscription is done after the handshake. JavaScript Code

问题 Is it possible to connect cometD client with Kafka producer? Any suggestions? Currently I am having a CometD client in python which is extracting data real time from a Salesforce object.

How can I connect GWT to CometD/Bayeux events?

旧城冷巷雨未停 提交于 2019-12-23 17:07:00
问题 I've got a GWT application, which periodically needs to update the screen with new tick items as they come in. We also have messages published by a CometD/Bayeux server (for a different AJAX application) and I'd like to consume them in my GWT. Of course, I can drop into JavaScript, hook up Dojo, and receive callbacks in the JavaScript layer - and from there, route a call into GWT Java code via a JSNI - but there doesn't appear to be any support in GWT directly for using long push or async
