How the java client in cumulocity listens to events?

独自空忆成欢 提交于 2019-12-02 08:46:18
Aim is to build a java client that subscribe and listen to a channel. Then process the arriving events from the cumulocity server to hadoop. First it was difficult to connect(subscribe) to the cumulocity server using the java client. However, now we have subscriber in place( as we are able to get some value against it as explained in the code comments). Next we want is the subscriber listen to the channel that we have defined in cumulocity server. But we could not get any method or anything useful in the cumulocity java docs that will help to achieve this step. Here is the code. I have

一:js端使用方式 =================================================== 第一步 :初始化cometd配置, $.cometd.configure({ url: cometdURL, logLevel: 'debug' }); 有两种方式: =================================================== 一:通过 URL string cometd.configure('http://localhost:8080/cometd'); 二:通过配置对象的方式: cometd.configure({ url: 'http://localhost:8080/cometd' }); 通过第二种方式配置cometd时,对象属性如下: url:连接URL logLevel:日志级别,默认为info,可支持warn、info、debug maxConnections:客户端连接到cometd服务端最大连接数量,默认为2,根据浏览器的不同,可以更改浏览器默认支持最大连接的相应值 backoffIncrement:与服务器连接失败后,等待重连的增量时间,默认为1000,单位为毫秒。如:第一次重连为1s,则第二次重连为2s以后,第三次3s,以此类推 maxBackoff:最大重连增量时间,默认为60000ms

Python Comet Server

懵懂的女人 提交于 2019-11-26 18:21:41
I am building a web application that has a real-time feed (similar to Facebook's newsfeed) that I want to update via a long-polling mechanism. I understand that with Python, my choices are pretty much to either use Stackless (building from their Comet wsgi example) or Cometd + Twisted. Unfortunately there is very little documentation regarding these options and I cannot find good information online about production scale users of comet on Python. Has anyone successfully implemented comet on Python in a production system? How did you go about doing it and where can I find resources to implement
