问题 I'm working on react native push notifications. i'm looking for some answers before i make a purchase to any third party notification provider Why do third party notifications providers such as OneSignal, Pusher & PubNub are based on Firebase Cloud Messaging?

问题 I'm designing an application that using PubNub for real-time message. I'm facing with an issue about 1-to-1 chatting. This is my scenario : I have an user A, so if A wants to receive all messages from another, A must subscribe a public channel, called PUB channel. User B know the public channel of A, so B or another can send messsage to this channel. Right now that fine. BUT when i open the app, i want to display the list of users that i've messaged or offline messages that a NEW person sent

问题 I am using PubNub for an IOS app (IOS SDK 8.0). When I am trying to unsubscribe from a channel on "applicationDidEnterBackground" event, I get the following console output. It says the channel is unsubscribed, but when I check from admin console I am still on the channel. Can you give some advice on this ? Here is the line I am using in "applicationDidEnterBackground": PubNub.unsubscribeFromChannel(channelToReceive,{(list, err:PNError!)-> Void in if(err != nil){ println(err

问题 I'd like to list all channels associated with a subscribe key that have active subscribers. Is there a way to do that with pubnub? I am using the JavaScript API if that makes any difference. 回答1: PubNub Where Now API Return a list of channels, associated with a subscribe key, where subscribers exist. PUBNUB.where_now( { uuid : 'optional-uuid' }, function(data) { console.log(data); } ); Note at the time of this posting, where_now() is only available in +3.6 SDK versions. 来源： https:/

问题 Has anyone managed to integrate pubnub and head.js properly? Pubnub expect me to put their script at the bottom of the page with a <div> tag just before it. This ensures that the ` tag is completely loaded by the time the javascript is called last. The thing is, the rest of my application and pubnub are loaded through head.js so it keeps happening that the JS files are loaded before the pubnub subscribe/publish key and its subscribing/publishing to 'demo' rather than my own area of pubnub...

问题 For example, the Java API for pubnub is at https://github.com/pubnub/pubnub-api/tree/master/java I want to create a single jar file from all the java files in the subfolders. What is the most straight-forward way to do that? 回答1: Since Pubnub provided no build file, you need to create a new java project in your favourite IDE and then import the downloaded java code. Next, you can compile and package the project into jar file using the IDE. Note: it is also possible to create a build script

问题 I recently began using PubNub in my iOS app, and am very happy with it. However, I have been looking at the other options available, such as Pusher and Realtime.co, which use Websockets. PubNub, on the other hand, uses long polling. I have done my own little speed comparisons and for my purposes, I find that they are all fast enough. PubNub offers some nice features like message history and a list of everyone in the channel , so barring everything else I am leaning toward them. My question is

问题 I am doing R&D on how to implement a pubnub access manager in swift, and after some research, I come to know : Swift SDK does not include pubnub.grant I need to achieve this using a pubnub function for serverless computing I have created one function in the pubnub dashboard and created a module PubNub, also created a function with event type "On Request" and added code of grant. export default (request, response) => { const pubnub = require('pubnub'); const kvstore = require('kvstore'); let

问题 I am trying to understand the pricing shceme of Pusher. According to their pricing, the Boostrap allows 100 max. Connections . My question is this: if I have 10,000 daily visitors to my page, each one subscribed to a different channel to receive messages, how much I need to pay. With realtime.co it's easier to understand because I know that I pay $1.00 per 1,000,000 messages without any other limitations. So I need to know how to calculate and estimate the total cost for my application,
