如何在node.js中创建命名管道?

How to create a named pipe in node.js?

P.S .: 现在，我将如下创建一个命名管道.但是我认为这不是最好的方法

P.S.: For now I'm creating a named pipe as follows. But I think this is not best way

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);
    }
});

推荐答案

Node核心不支持名称管道，例如Ben Noordhuis 10/11/11:

Looks like name pipes aren't and won't be supported in Node core - from Ben Noordhuis 10/11/11:

Windows具有命名管道的概念，但是自从您提到mkfifo以来，我 假设您是指UNIX FIFO.

Windows has a concept of named pipes but since you mention mkfifo I assume you mean UNIX FIFOs.

我们不支持它们，可能永远也不会(非阻塞中的FIFO 模式有可能死锁事件循环)，但您可以使用 如果需要类似的功能，请使用UNIX套接字.

We don't support them and probably never will (FIFOs in non-blocking mode have the potential to deadlock the event loop) but you can use UNIX sockets if you need similar functionality.

命名管道和套接字非常相似，但是net模块通过指定path而不是host和port来实现本地套接字:

Named pipes and sockets are very similar however, the net module implements local sockets by specifying a path as opposed to a host and port:

• http://nodejs.org/api/net.html#net_server_listen_path_callback
• http://nodejs.org/api/net.html#net_net_connect_path_connectlistener

• http://nodejs.org/api/net.html#net_server_listen_path_callback
• http://nodejs.org/api/net.html#net_net_connect_path_connectlistener

示例:

var net = require('net');

var server = net.createServer(function(stream) {
  stream.on('data', function(c) {
    console.log('data:', c.toString());
  });
  stream.on('end', function() {
    server.close();
  });
});

server.listen('/tmp/test.sock');

var stream = net.connect('/tmp/test.sock');
stream.write('hello');
stream.end();
