如果您不使用 HTTP(例如写入磁盘、直接 TCP/IP 链接、Websockets、MQTT 等),则这不适用。 话虽如此,我相信这个例子可能有点夸大了 Protobuf 的好处,因为大量的 HTTP 流量被压缩了(这篇文章报告了他们的测试中有 9% 的差异)。
Google Protocol Buffer 的使用和原理 简介:Protocol Buffers 是一种轻便高效的结构化数据存储格式,可以用于结构化数据串行化,很适合做数据存储或 RPC 数据交换格式。它可用于通讯协议、数据存储等领域的语言无关、平台无关、可扩展的序列化结构数据格式。目前提供了 C++、Java、Python 三种语言的 API。 Protobuf 的优...
