# Gevent-socketio documentation ## I ntroduction Socket.IO is a WebSocket-like abstraction that enables real-time communication between a browser and a server. gevent-socketio is a Python implementation implementation of the protocol. The reference server implementation of Socket.IO runs on Node.js and was developed by LearnBoost. There are now server implementations in a variety of languages. One aim of this gevent python WSGI server to use gevent-socketio. Namespaces: since you mostly have one websocket/socket.io endpoint per website, it is important to be able to namespace the different real-time activities

## 67 -328 Building Distributed Applications WebSockets ### HTTP / AJAX / WebSockets / Socket.io • Recall that HTTP is request/response protocol • AJAX allows you to do HTTP request/response within message • And send messages to the client ### Socket.io • Library for full-duplex communication between clients and servers - Built on engine.io, socket.io provides an abstraction above whatever transport transport methods are available in the browser: – WebSockets — Long Polling ### Socket.io • Also provides a simple abstraction for event-based programming across the server and multiple clients • Clients

## Supports multiple WebSocket libraries ThinkJS supports some common WebSocket libraries like socket.io and sockjs, and packages them to provide the consistent APIs to developers. ## Plentiful test cases various functions such as chatroom. ThinkJS supports a lot of WebSocket libraries, for instance, socket.io, sockjs etc. Further more, by giving a simple encapsulation to these libraries, ThinkJS provided WebSocket library name, defaults to socket.io allow_origin: '', // origin allowed adapter: undefined, // store adapter for socket, used in socket.io path: "", // url path for

接口，不用写任何的代码即可完成 REST API 的开发。如果想在 REST 接口中过滤字段或者进行权限校验，也很方便处理。 ## 支持多种 WebSocket 库 ThinkJS 支持 socket.io，sockjs 等常见的 WebSocket 库，并且对这些库进行包装，抹平各个库之间接口调用上的差异，给开发者一致的体验。 ## 丰富的测试用例 ThinkJS 含有 1500+ 的测试用例，代码覆盖率达到 Adapter 请参见 Adapter -> 介绍。 ## WebSocket 项目里经常要使用 WebSocket 来实现聊天等功能，ThinkJS 支持多种 WebSocket 库，如：socket.io，sockjs 等，并对这些库进行了一些简单的包装，让使用的接口一致。 ## 开启 WebSocket WebSocket 功能默认是关闭的，项目如果需要开启，可以修改配置文件 src/ 'socket.io', // 使用的 WebSocket 库类型，默认为 socket.io allow_origin: "", // 允许的 origin adapter: undefined, // socket 存储的 adapter, socket.io 下使用 path: "", // url path for websocket

JavaScript 包，将和 Laravel 5.3 一起发布，用于为订阅频 道以及在客户端 JavaScript 应用中监听服务器端事件提供了简单、优美的 API, Echo 包含对 Pusher 和 Socket.io 的支持： Echo.channel('orders.' + orderId) .listen('ShippingStatusUpdated', (e) => socket ID 的用户。 Socket.IO 如果你想配对 Redis 广播和 Socket.IO 服务器，则需要在应用的 HTML 元素 head 中引入 Socket.IO JavaScript 库： 接下来，你需要使用 socket.io 连接器和 host 来实例化 'socket.io', host: 'http://app.dev:6001' }; 最后，需要运行一个与之兼容的 Socket.IO 服务器。Laravel 并未内置一个 Socket.IO 服务器实现，不过，这里有一个第三方实现的 Socket.IO 驱动：tlaverdure/laravel-echo-server。 ## 队列预备知识 在开始介绍广播事件之前，还需要配置并
