1、简介
1.1 node
Node.js 是一个开源的、跨平台的 JavaScript 运行时环境。
Node.js 是一个开源和跨平台的 JavaScript 运行时环境。 它是几乎任何类型项目的流行工具!
Node.js 在浏览器之外运行 V8 JavaScript 引擎(Google Chrome 的内核)。 这使得 Node.js 非常高效。
Node.js 应用在单个进程中运行,无需为每个请求创建新线程。 Node.js 在其标准库中提供了一组异步 I/O 原语,以防止 JavaScript 代码阻塞,并且通常,Node.js 中的库是使用非阻塞范例编写的,这使得阻塞行为成为异常而不是常态。
1.2 Protobuf
Protobuf 是一种用于 序列化 和 反序列化 对象的格式规范(rpc 通信协议)。
Protobuf 与 非结构化格式(如 JSON、XML)最大的区别在于,你必须为 protobufs 定义数据类型,最常用的方式是定义 .proto 文件。
Google Protocol Buffer( 简称 Protobuf) 是 Google 公司内部的混合语言数据标准,目前已经正在使用的有超过 48,162 种报文格式定义和超过 12,183 个 .proto 文件。他们用于 RPC 系统和持续数据存储系统。
Google 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,或者说序列化。它很适合做数据存储或 RPC 数据交换格式。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(即时通讯网注:Protobuf官方工程主页上显示的已支持的开发语言多达10种,分别有:C++、Java、Python、Objective-C、C#、JavaNano、JavaScript、Ruby、Go、PHP,基本上主流的语言都已支持.
2、下载和安装
2.1 node
https://nodejs.org/zh-cn
https://nodejs.org/zh-cn/download
2.2 Protobuf
https://github.com/protocolbuffers/protobuf
https://github.com/protobufjs/protobuf.js
https://protobufjs.github.io/protobuf.js/
protobuf.js是一个纯JavaScript实现,支持Node.js和浏览器的TypeScript,它容易使用速度快速,可以直接反射.proto文件,不需要生成任何文件。
protobuf.js是基于ByteBuffer.js的Protocol Buffers纯JavaScript实现,主要功能是解析.proto文件,构建Message类,编码解码。
2.2.1 安装
npm install protobufjs [--save --save-prefix=~]
npm i -g protobufjs
# The command line utility lives in the protobufjs-cli package and must be installed separately:
npm install protobufjs-cli [--save --save-prefix=~]
2.2.2 工具
https://protobufjs.github.io/protobuf.js/#pbjs-for-javascript
#老版本
##使用pbjs命令将.proto文件转换为.js文件
./node_modules/protobufjs/bin/pbjs -t json msg.proto > msg.json
## 使用pbjs命令将.proto文件转换为.json文件
./node_modules/protobufjs/bin/pbjs -t static_module -w commonjs -o msg.js msg.proto
#新版本
npx pbjs -t json message.proto --es6 "msg.js"
npx pbjs -t json message.proto --ts "msg.ts"
而在node端,也可以打包成js文件来处理。但node端是服务端环境了,完全可以允许.proto的存在,所以其实我们可以有优雅的使用方式:直接解析。
使用pbjs命令将.proto文件转换为.json文件:
./node_modules/protobufjs/bin/pbjs -t json msg.proto > msg.json
./protobuf.js-protobufjs-v7.2.5/cli/bin/pbjs -t json msg.proto > msg.json
- 命令行参数如下:
-t, --target Specifies the target format. Also accepts a path to require a custom target.
json JSON representation
json-module JSON representation as a module
proto2 Protocol Buffers, Version 2
proto3 Protocol Buffers, Version 3
static Static code without reflection (non-functional on its own)
static-module Static code without reflection as a module
-p, --path Adds a directory to the include path.
-o, --out Saves to a file instead of writing to stdout.
--sparse Exports only those types referenced from a main file (experimental).
Module targets only:
-w, --wrap Specifies the wrapper to use. Also accepts a path to require a custom wrapper.
default Default wrapper supporting both CommonJS and AMD
commonjs CommonJS wrapper
amd AMD wrapper
es6 ES6 wrapper (implies --es6)
closure A closure adding to protobuf.roots where protobuf is a global
-r, --root Specifies an alternative protobuf.roots name.
-l, --lint Linter configuration. Defaults to protobuf.js-compatible rules:
eslint-disable block-scoped-var, no-redeclare, no-control-regex, no-prototype-builtins
--es6 Enables ES6 syntax (const/let instead of var)
Proto sources only:
--keep-case Keeps field casing instead of converting to camel case.

3、node 代码示例
3.1 HTTP
一旦你已经安装了 Node,让我们尝试构建第一个 Web 服务器。然后使用 node server.js 运行程序,访问 http://localhost:3000,你就会看到一个消息,写着“Hello World”。
- server.js
const http = require('http');
const hostname = '127.0.0.1';
const port = 3000;
const server = http.createServer((req, res) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain;charset=utf-8');
res.end('Hello World, 爱看书的小沐!2023!\n');
});
server.listen(port, hostname, () => {
console.log(`服务器运行在 http://${hostname}:${port}/`);
});
运行脚本:
node server.js
浏览器访问http服务器:
http://127.0.0.1:3000/
var http = require('http');
var hostname = '127.0.0.1';
var port = 3000;
http.createServer(function(req, res) {
res.writeHead(200, {'Content-Type': 'text/html'});
res.write('<head><meta charset="utf-8"/></head>');
res.write('<h1>Node.js</h1>');
res.write('<b>爱看书的小沐!2023!</b>');
res.end('<p>Hello World</p>');
}).listen(port);
console.log("HTTP server is listening at port ${port}.");
console.log(`服务器运行在 http://${hostname}:${port}/`);
3.2 UDP单播
UDP单播例子一
- 制作一个文件 (“demo_dgram.js”) 监听 8080 端口上的消息:
var dgram = require('dgram');
var s = dgram.createSocket('udp4');
s.on('message', function(msg, rinfo) {
console.log('I got this message: ' + msg.toString());
});
s.bind(8080);
- 制作一个向 8080 端口发送消息的文件(“demo_dgram_send.js”) :
var dgram = require('dgram');
var s = dgram.createSocket('udp4');
s.send(Buffer.from('abc'), 8080, 'localhost');
UDP单播例子二
- 服务器:udp_server.js
// 例子:UDP服务端
var PORT = 9090;
var HOST = '127.0.0.1';
var dgram = require('dgram');
var server = dgram.createSocket('udp4');
server.on('listening', function () {
var address = server.address();
console.log('UDP Server listening on ' + address.address + ":" + address.port);
});
server.on('message', function (message, remote) {
console.log(remote.address + ':' + remote.port +' - ' + message);
});
server.bind(PORT, HOST);
- 客户端:udp_client.js
// 例子:UDP客户端
var PORT = 9090;
var HOST = '127.0.0.1';
var dgram = require('dgram');
var message = Buffer.from('This is 爱看书的小沐!');
var client = dgram.createSocket('udp4');
client.send(message, PORT, HOST, function(err, bytes) {
if (err) throw err;
console.log('UDP message sent to ' + HOST +':'+ PORT);
client.close();
});
3.4 UDP广播
- 服务器:boardcast_server.js
var dgram = require('dgram');
var server = dgram.createSocket('udp4');
var port = 8080;
server.on('message', function(message, rinfo){
console.log('server got message from: ' + rinfo.address + ':' + rinfo.port);
});
server.on('listening', function () {
var address = server.address();
console.log('Boardcast Server listening on ' + address.address + ":" + address.port);
});
server.bind(port);
- 客户端:boardcast_client.js
var dgram = require('dgram');
var client = dgram.createSocket('udp4');
var msg = Buffer.from('hello world, 爱看书的小沐!');
var port = 8080;
var host = '255.255.255.255';
client.bind(function(){
client.setBroadcast(true);
// client.send(msg, port, host, function(err){
// if(err) throw err;
// console.log('msg has been sent');
// client.close();
// });
// 循环发送消息
setInterval(function(){
client.send(msg, port, host, function(err){
if(err) throw err;
console.log('msg has been sent');
});
}, 1000);
});
4、Protobuf 代码示例
4.1 例子: awesome.proto
- awesome.proto的内容定义如下:
// awesome.proto
package awesomepackage;
syntax = "proto3";
message AwesomeMessage {
string awesome_field = 1; // becomes awesomeField
string name_field = 2;
}
4.1.1 加载.proto文件方式
- 测试脚本文件:app_proto001.js
var protobuf = require("protobufjs");
protobuf.load("awesome.proto", function(err, root) {
if (err)
throw err;
var AwesomeMessage = root.lookupType("awesomepackage.AwesomeMessage");
var payload = { awesomeField: "AwesomeString" };
var message = AwesomeMessage.create(payload);
var buffer = AwesomeMessage.encode(message).finish();
});
var protobuf = require("protobufjs");
protobuf.load("awesome.proto", function(err, root) {
if (err)
throw err;
// Obtain a message type
var AwesomeMessage = root.lookupType("awesomepackage.AwesomeMessage");
// Exemplary payload
var payload = { awesomeField: "AwesomeString" };
console.log("payload: " + JSON.stringify(payload));
// Verify the payload if necessary (i.e. when possibly incomplete or invalid)
var errMsg = AwesomeMessage.verify(payload);
if (errMsg)
throw Error(errMsg);
// Create a new message
var message = AwesomeMessage.create(payload); // or use .fromObject if conversion is necessary
console.log("create: " + JSON.stringify(message));
// Encode a message to an Uint8Array (browser) or Buffer (node)
var buffer = AwesomeMessage.encode(message).finish();
// ... do something with buffer
console.log("encode: " + JSON.stringify(buffer));
// Decode an Uint8Array (browser) or Buffer (node) to a message
var message = AwesomeMessage.decode(buffer);
// ... do something with message
console.log("decode: " + JSON.stringify(message));
// If the application uses length-delimited buffers, there is also encodeDelimited and decodeDelimited.
// Maybe convert the message back to a plain object
var object = AwesomeMessage.toObject(message, {
longs: String,
enums: String,
bytes: String,
// see ConversionOptions
});
console.log("toObject: " + JSON.stringify(object));
});
执行运行命令如下:
node app_proto001.js
4.1.2 加载.json文件方式
执行如下命令,将awesome.proto转为awesome.json:
./node_modules/protobufjs/bin/pbjs -t json awesome.proto > awesome.json
自动生成的awesome.json如下:
{
"nested": {
"awesomepackage": {
"nested": {
"AwesomeMessage": {
"fields": {
"awesomeField": {
"type": "string",
"id": 1
},
"nameField": {
"type": "string",
"id": 2
}
}
}
}
}
}
}
编写脚本代码如下:
var protobuf = require("protobufjs");
var jsonDescriptor = require("./awesome.json"); // exemplary for node
var root = protobuf.Root.fromJSON(jsonDescriptor);
// Obtain a message type
var AwesomeMessage = root.lookupType("awesomepackage.AwesomeMessage");
// Exemplary payload
var payload = { awesomeField: "AwesomeString", nameField: "AwesomeName"};
console.log("payload: " + JSON.stringify(payload));
// Verify the payload if necessary (i.e. when possibly incomplete or invalid)
var errMsg = AwesomeMessage.verify(payload);
if (errMsg)
throw Error(errMsg);
// Create a new message
var message = AwesomeMessage.create(payload); // or use .fromObject if conversion is necessary
console.log("create: " + JSON.stringify(message));
// Encode a message to an Uint8Array (browser) or Buffer (node)
var buffer = AwesomeMessage.encode(message).finish();
// ... do something with buffer
console.log("encode: " + JSON.stringify(buffer));
// Decode an Uint8Array (browser) or Buffer (node) to a message
var message = AwesomeMessage.decode(buffer);
// ... do something with message
console.log("decode: " + JSON.stringify(message));
// If the application uses length-delimited buffers, there is also encodeDelimited and decodeDelimited.
// Maybe convert the message back to a plain object
var object = AwesomeMessage.toObject(message, {
longs: String,
enums: String,
bytes: String,
// see ConversionOptions
});
console.log("toObject: " + JSON.stringify(object));
运行结果如下:
4.1.3 加载.js文件方式
通过如下命令转为.proto为对应的.js文件
C:\Users\tomcat\Desktop\test>C:\Users\tomcat\Desktop\protobuf.js-protobufjs-v7.2.5\node_modules\.bin\pbjs -t static-module -w commonjs -o awesome.js awesome.proto
生成的awesome.js 部分内容如下:
编写测试脚本代码如下:
var protobuf = require("protobufjs");
var awesomeProto = require("./awesome.js"); // exemplary for node
var AwesomeUtils = awesomeProto.awesomepackage.AwesomeMessage;
// Exemplary payload
var payload = { awesomeField: "AwesomeString", nameField: "AwesomeName"};
console.log("payload: " + JSON.stringify(payload));
// Verify the payload if necessary (i.e. when possibly incomplete or invalid)
var errMsg = AwesomeUtils.verify(payload);
if (errMsg)
throw Error(errMsg);
// Create a new message
var message = AwesomeUtils.create(payload); // or use .fromObject if conversion is necessary
console.log("create: " + JSON.stringify(message));
// Encode a message to an Uint8Array (browser) or Buffer (node)
var buffer = AwesomeUtils.encode(message).finish();
// ... do something with buffer
console.log("encode: " + JSON.stringify(buffer));
// Decode an Uint8Array (browser) or Buffer (node) to a message
var message = AwesomeUtils.decode(buffer);
// ... do something with message
console.log("decode: " + JSON.stringify(message));
// If the application uses length-delimited buffers, there is also encodeDelimited and decodeDelimited.
// Maybe convert the message back to a plain object
var object = AwesomeUtils.toObject(message, {
longs: String,
enums: String,
bytes: String,
// see ConversionOptions
});
console.log("toObject: " + JSON.stringify(object));
运行脚本文件如下:
node app_awesome.js
4.2 例子:account.proto
- account.proto
// account.proto
package yxy;
syntax = "proto3";
message Account{
required string name = 1; //帐号名

required int32 index = 1;
repeated Account list = 2;
}
4.2.1 create(…)创建对象
- app_account.js
var ProtoBufJs = require("protobufjs");
var root = ProtoBufJs.loadSync("./account.proto");
var AccountList = root.lookupType("yxy.AccountList");
var Account = root.lookupType("yxy.Account");
var accountListObj = AccountList.create();
for(var i = 0; i < 10; i++){
var accountObj = Account.create();
accountObj.name = "杨小羊_"+i;
accountObj.pwd = "pwd_"+i;
accountListObj.list.push(accountObj);
}
var buffer = AccountList.encode(accountListObj).finish();
console.log("data: " + JSON.stringify(accountListObj));
console.log("encode: " + JSON.stringify(buffer));
执行命令如下:
node app_account.js
4.2.2 fromObject(…)创建对象
var ProtoBufJs = require("protobufjs");
var root = ProtoBufJs.loadSync("./account.proto");
var AccountList = root.lookupType("yxy.AccountList");

var accountObj1 = Account.fromObject({pwd:"666", name:"杨小羊"});
var accountObj2 = Account.fromObject({pwd:"777", name:"杨大羊"});
var accountObj3 = Account.fromObject({pwd:"888", name:"杨胖羊"});
var accountListObj = AccountList.fromObject({index:"0", list:[accountObj1,accountObj2,accountObj3]});
var buffer = AccountList.encode(accountListObj).finish();
console.log("data: " + JSON.stringify(accountListObj));
console.log("encode: " + JSON.stringify(buffer));
执行结果如下:

var HOST = '127.0.0.1';
var server = dgram.createSocket('udp4');
var root = ProtoBuf.loadSync("./hello.proto");

4.5 例子:user.proto + websocket
WebSocket是HTML5新增的协议,它的目的是在浏览器和服务器之间建立一个不受限的双向通信的通道,比如说,服务器可以在任意时刻发送消息给浏览器。任何一方都可以主动发消息给对方。
HTTP协议是一个请求-响应协议,请求必须先由浏览器发给服务器,服务器才能响应这个请求,再把数据发送给浏览器。换句话说,浏览器不主动请求,服务器是没法主动发数据给浏览器的。
WebSocket并不是全新的协议,而是利用了HTTP协议来建立连接。
安装ws库:
npm i ws
- user.proto
syntax = "proto3";
package yxy;
message Login {
required string name = 1;
required string pwd = 2;
}
message Address{
string province = 1;
string city = 2;
string country = 3;
}
4.5.1 服务端:yxy_wsserver.js
- yxy_wsserver.js
const protobuf = require("protobufjs");
const PORT = 3000;
const HOST = '127.0.0.1';
protobuf.load("./user.proto", (err, root) => {
if (err) throw err;
const LoginMessage = root.lookupType("yxy.Login");
const WebSocket = require('ws')
const WebSocketServer = WebSocket.Server;
const wss =new WebSocketServer({
port:PORT
})
//如果有WebSocket请求接入,wss对象可以响应connection事件来处理这个WebSocket:
wss.on('connection',function(ws){ //在connection事件中,回调函数会传入一个WebSocket的实例,表示这个WebSocket连接。
console.log(`[SERVER] connection()`);
ws.on('message',function(message){
console.log(`[SERVER] Received:${message}`);
// 解码数据
const payload = LoginMessage.decode(message);
// 在这里处理消息
console.log(payload);
// 编码响应
const responseData = LoginMessage.encode({
name: "杨小羊",
pwd: "111111"
}).finish();
const msg = responseData.toString();
ws.send(`ECHO:${msg}` ,(err)=>{
if(err){
console.log(`[SERVER] error:${err}`);
}
})
})
})
});
- 运行结果如下:
4.5.2 客户端:yxy_wsclient.js
- yxy_wsclient.js
const ws = require('nodejs-websocket');
const protobuf = require("protobufjs");
const PORT = 3000;
const HOST = '127.0.0.1';
protobuf.load("./user.proto", (err, root) => {
if (err) throw err;
const LoginMessage = root.lookupType("yxy.Login");
const WebSocket = require('ws')
let ws = new WebSocket('ws://localhost:3000');
// 打开WebSocket连接后立刻发送一条消息:
ws.on('open', function () {
console.log(`[CLIENT] open()`);
//每隔一秒向服务器发送消息,以便后面每隔一秒收到消息
setInterval(function(){
// 编码数据
const data = LoginMessage.encode({
name: "爱看书的小沐",
pwd: "222222"
}).finish();
// 将数据写到连接
ws.send(data);
console.log(`[CLIENT] Send: ${data}`);
},1000)
});
// 响应收到的消息:
ws.on('message', function (message) {
console.log(`[CLIENT] Received: ${message}`);
const loginResponse = LoginMessage.decode(message);
console.log(loginResponse);
})
});
- 运行结果如下:
