WebSockets 还是带有 phonegap 的替代方案? [英] WebSockets or an alternative with phonegap?

问题描述

如何使用 phonegap 将低延迟数据发送到服务器并返回?

How can I send low latency data to a server and back with phonegap?

考虑到我无法在本地访问 php 文件，并且没有使用 node.js 或 WebSockets 的经验，我不知道应该使用哪些.

Considering I don't have access to php files locally, and don't have experience with node.js or WebSockets I don't know which ones I should use.

推荐答案

Android 或 iOS 下旧版本的 Cordova，这意味着如果你想使用 PhoneGap 插件在客户端上使用它们.

WebSockets aren't natively supported by the browsers in Android or older versions of Cordova under iOS, which means you'll need to use a PhoneGap plugin if you want to use them on the client.

但是，我不确定(即使使用插件)当设备在网络连接(WiFi -> 3G -> WiFi)之间移动时 WebSockets 的弹性可能如何，因此使用简单的轮询 Web 服务可能是一个如果您的应用需要在用户四处走动时继续接收数据，则这是更可靠的选择.

However, I'm not sure (even with the plugin) how resilient WebSockets are likely to be when the device moves between network connections (WiFi -> 3G -> WiFi), so using a simple polling web service may be a more reliable option if your app needs to continue receiving data as your users move around.

如果您需要接收服务器发起的数据，请考虑改用推送通知:iOS (APN) 和 Android (C2DM) 都提供 API 来执行此操作，这比让您的应用轮询服务器更有效地利用电池不断.

If you need to receive data initiated by the server, consider using push notifications instead: both iOS (APN) and Android (C2DM) provide APIs to do this which make more efficient use of the battery than having your app poll your server constantly.
