node.js - 如何在 node.js 中创建命名管道？

Question

如何在 node.js 中创建命名管道？

附:现在我正在创建一个命名管道，如下所示。但我认为这不是最好的方法

var mkfifoProcess = spawn('mkfifo',  [fifoFilePath]);
mkfifoProcess.on('exit', function (code) {
    if (code == 0) {
        console.log('fifo created: ' + fifoFilePath);
    } else {
        console.log('fail to create fifo with code:  ' + code);
    }
});

Answer 1

在 Windows 上使用命名管道

Node v0.12.4

var net = require('net');

var PIPE_NAME = "mypipe";
var PIPE_PATH = "\\\\.\\pipe\\" + PIPE_NAME;

var L = console.log;

var server = net.createServer(function(stream) {
    L('Server: on connection')

    stream.on('data', function(c) {
        L('Server: on data:', c.toString());
    });

    stream.on('end', function() {
        L('Server: on end')
        server.close();
    });

    stream.write('Take it easy!');
});

server.on('close',function(){
    L('Server: on close');
})

server.listen(PIPE_PATH,function(){
    L('Server: on listening');
})

// == Client part == //
var client = net.connect(PIPE_PATH, function() {
    L('Client: on connection');
})

client.on('data', function(data) {
    L('Client: on data:', data.toString());
    client.end('Thanks!');
});

client.on('end', function() {
    L('Client: on end');
})

输出:

Server: on listening
Client: on connection
Server: on connection
Client: on data: Take it easy!
Server: on data: Thanks!
Client: on end
Server: on end
Server: on close

关于管道名称的注意事项:

C/C++ / Nodejs:
\\.\pipe\PIPENAME CreateNamedPipe

.Net / Powershell:
\\.\PIPENAME NamedPipeClientStream / NamedPipeServerStream

Both will use file handle:
\Device\NamedPipe\PIPENAME
