How is GMail Chat able to make AJAX requests without client interaction?

我是研究僧i 提交于 2019-11-28 15:14:50
All HTTP responses require the client to initiate them, even those made using AJAX. But GMail's chat feature is able to receive messages from other users, even when I'm just sitting in my comfy computer chair watching but not interacting with the browser. How did they do it? Pablo Fernandez That tech is known as "comet", but also as "server push", "reverse ajax", etc. It's about pushing data from the server to the browser, keeping an http connection alive. Find more info on it on the wikipedia article ( English version ). Also here's a pretty good presentation with Joe Walker from DWR, where

Android - Firebase - Send Users to Chat Room

荒凉一梦 提交于 2019-11-28 14:34:56
Aim Allowing the Users to access their selected Group Chat. Once the user clicks on the Group Chat name, they will be entered into that Group Chat. Database Tree As shown in the Database Tree, the Currently Signed In user will be shown a list of Group Chat names that have been created. I have an Admin Account to create these Group Chats for the users. The Android, Asia, and Europe group chats that are seen within the Database ARE NOT fixed variables. They are names. A newly Group Chat name could be "Earth". Therefore there is no way of calling it by a variable other than calling it by the Node

Firebase Hosting on own server

时光毁灭记忆、已成空白 提交于 2019-11-28 13:29:04
I am looking for a solution for developing iOS and Android chat to replace our current (unreliable, maybe poorly written by previous devs) XMPP/OpenFire chat. I came across Firebase which looks good. However, I don't quite get the setup for it. Can I host Firebase on my own server and not have to subscribe to any of Firebase's plans? Firebase offers a few products: the Firebase realtime database Firebase hosting (for hosting static resources) Firebase authentication I think you are looking for the Firebase realtime database. There is no way currently to host the Firebase realtime database on

Socket io chat - disconnecting clients randomly ping timeout and transport close errors ver 2.2.0

前提是你 提交于 2019-11-28 10:59:52
问题 I have a chat app running on Node JS express with Socket io. Previously clients were getting disconnected when they send a large picture over 4 MB, i found out socket io cannot handle/stream/send such large data in Base64 over socket emit events. So I ended up using this socket io file upload module. Now I am using socket io file upload module to let users upload pics/files during their chats. Now even if i upload biggest images/files chat doesn't get disconnect. However, clients are still

Using memcached as a database buffer for chat messages

大兔子大兔子 提交于 2019-11-28 09:28:14
I am playing around with building a chat application using PHP and CodeIgniter. For this, I am implementing a cache 'buffer' with memcached to hold the most recent chat messages in memory, reducing load on the database. What I want to do is this: When a message arrives, I save it in memcached using the current minute (YYYY-MM-DD-HH-MM) as the key. No database I/O involved. The idea being that all messages from the same minute are collected under the same key. Users receive new chat messages also fetched from memcached (for now I'm using long-polling, but this will move to WebSockets under Node

This chat application is for sending messages from one device to another using internet(GPRS,3G,etc) from this application. please tell me a way to implement this.
