在Windows上使用NodeJS的Protobuf [英] Protobuf with NodeJS on Windows

问题描述

我想从Windows上的NodeJS脚本向设备（Karotz）发送简单的TCP消息。

I would like to send simple TCP message to a device (Karotz) from NodeJS Script on Windows.

• NodeJS正确安装工作


• TCP连接正常工作


• 这是我的.proto文件（http://wiki.karotz.com/index.php/Voos-message。 proto）


• 我使用google的protoc将其编译为.desc

• NodeJS correctly installed an working
• TCP connection working
• Here is my .proto file (http://wiki.karotz.com/index.php/Voos-message.proto)
• I compile it to .desc using google's protoc

我不知道如何构建我的消息以将其发送到设备？

I don't know how to build my message to send it to the device ?

• 我读了 Google说明


• 并且 protobuff_for_node 和其他fork

• I read Google Description
• And protobuff_for_node and other fork

但我不明白如何安装它在窗户上。由于原生图书馆，似乎很复杂。

But I don't understand how to install it on windows. Seems complicated because of native librarie.

是否有简单的javascript图书馆读取.desc Schema并构建消息？没有本机代码或复杂的东西？

Is there dead simple javascript librarie that read the .desc Schema and build the message ? Without native code or complicated stuff ?

推荐答案

如果您正在使用Node.js，那么只使用NPM包版本更简单protobuf库它会为你构建它，假设你的机器上有一个C ++编译器：

If you're using Node.js it's simpler to just use the NPM package version of the protobuf library it'll build it for you, assuming you have a C++ compiler on your machine:

> npm install protobuf

建立你的信息&解析和现有消息：

To build your message & parse and existing message:

var Schema    = require('protobuf').Schema;
var readFile  = require('fs').readFileSync;
var schema = new Schema(readFile(__dirname+'/Voos-message.desc'));
var VooMsg = schema['net.violet.voos.message.VoosMsg'];

// Convert to protobuf format
var msg = VooMsg.serialize({id:1, correlationId: 'hello'});

// Read it back
var outMsg = VooMag.parse(msg);

protobuf库运行良好且易于使用。但如果您想要一个纯JS版本，请查看： ProtoBufJS

The protobuf library works very well and is easy to use. But if you want a pure JS version, have a look at: ProtoBufJS
