Google Protocol Buffers: JavaScript Example
提问by nikolakoco
Is it a good choice to use Google Protocol Buffers in JavaScript or is it better to do it with JSON?
在 JavaScript 中使用 Google Protocol Buffers 是一个不错的选择，还是使用 JSON 更好？
Also it'd be great if someone can give me a simple example about Protocol Buffers implementation in JavaScript. The documentation on the Google's site is scarce.
另外，如果有人能给我一个关于 JavaScript 中协议缓冲区实现的简单示例，那就太好了。Google 网站上的文档很少。

[edit] Google's open source implementation of protocol buffers is available on github

The official protobuf project support only Java, C++, and Python. Not Javascript.
官方 protobuf 项目仅支持 Java、C++ 和 Python。不是 JavaScript。
According to the Wiki of the project, there are three projects porting protocol buffers to Javascript.
根据该项目的 Wiki，有三个项目将协议缓冲区移植到 Javascript。
- Protobuf.js: https://github.com/dcodeIO/ProtoBuf.js
- protobuf-js: http://code.google.com/p/protobuf-js/
- protojs: http://github.com/sirikata/protojs
- Protobuf.js：https: //github.com/dcodeIO/ProtoBuf.js
- protobuf-js：http: //code.google.com/p/protobuf-js/
- protojs：http://github.com/sirikata/protojs
Protobuf.js is up-to-date. protobuf-js has not been updated for two years, so I would favor Protobuf.js.
Protobuf.js 是最新的。protobuf-js 已经两年没有更新了，所以我更喜欢 Protobuf.js。
The question still is "Why"?: protobuf may be a bit smaller, especially when a lot of numeric values are transferred, but JSON is simply the more common protocol in the JS space and probably better supported and easier to integrate into other tools.
问题仍然是“为什么”？：protobuf 可能更小一些，尤其是在传输大量数值时，但 JSON 只是 JS 空间中更常见的协议，并且可能得到更好的支持并且更容易集成到其他工具中。

Try Protostuff!
试试Protostuff吧！
I had a bit of hard time configuring but I'm sure that was more of my issue. You can serialize/deserialize a protobuff/protostuff message to/from JSON. I'm at the early stages of using this but it looks promising so far.
我在配置时遇到了一些困难，但我确信那更多是我的问题。您可以将 protobuff/protostuff 消息序列化/反序列化到/从 JSON。我正处于使用它的早期阶段，但到目前为止它看起来很有希望。
