node.js - Node-Redis psubscribe with custom messages -


i under impression using library:

https://github.com/mranney/node_redis

could this:

var redis = require('redis');  var pub = redis.createclient(); var sub = redis.createclient();  sub.psubscribe('channel');  sub.on('message channel', function(){});  pub.publish('channel','a message xyz');

the problem can't seem sub.on() receive specific custom message. entry point seems fired sub.on('message') or sub.on('pmessage'), how can sub.on('my custom message') invoked? hope makes sense.

this how node redis client works. reserves message , pmessage emit events notifying of subscribe , psubscribe events respectively.

https://github.com/mranney/node_redis#publish--subscribe

but if want syntax have in code can define own message format , eventemitter, maybe:

var events = require('events'); var redis = require('redis'); var pub = redis.createclient(); var sub = redis.createclient();  var ee = new events.eventemitter();  ee.on('aweomseevent', function() {     console.log('party!'); });  sub.on('subscribe', function() {     var message = {         type: 'aweomseevent',         isawesome: true     };     pub.publish('mychannel', json.stringify(message)); });  sub.subscribe('mychannel'); sub.on('message', function(channel, message) {     var deserialized = json.parse(message);     if (deserialized.type) {         ee.emit(deserialized.type, deserialized);     } });

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
