php - 通过 UNIX 套接字连接 Node.JS 和 PHP - EPIPE 写入错误

Question

我正在尝试在 PHP 和 Node.JS 创建的应用程序之间建立一座桥梁。

Node.JS 创建套接字并监听它，我的代码:

var net = require('net'),
    fs = require('fs');
var path = '/tmp/echo.sock';

fs.unlink(path, function () {
  var server = net.createServer(function(c) {

    console.log('server connected');

    c.on('close', function() {
      console.log('server disconnected');
    });
    c.write('hello\r\n');

    c.on('data', function(data) {
        console.log('Response: "' + data + '"');
        c.write('You said "' + data + '"');
    });

  });
  server.listen(path, function(e) {
    console.log('server bound on %s', path);
  });
});

process.on('uncaughtException', function (err) {
    console.log( "UNCAUGHT EXCEPTION " );
    console.log( "[Inside 'uncaughtException' event] " + err.stack || err.message );
});

我的 PHP 代码只是与现有套接字连接并发送一些数据:

$fp = fsockopen("unix:///tmp/echo.sock", -1, $errno, $errstr);
if (!$fp) {
   return "ERROR: $errno - $errstr<br />\n";
} else {
   fwrite($fp, "Hello World <3");
   $out = fread($fp, 8192);
   fclose($fp);
   return $out; // That code is in function.
}

一切都应该正常，但在 Node.JS 控制台中我看到响应:

server bound on /tmp/echo.sock
server connected
Response: "Hello World <3"
UNCAUGHT EXCEPTION
[Inside 'uncaughtException' event] Error: write EPIPE
    at exports._errnoException (util.js:745:11)
    at Object.afterWrite (net.js:763:14)
server disconnected

在 PHP 中我只看到第一条消息，hello。为什么以及如何解决这个问题？

试试这个；

<?php
$fp = fsockopen("unix:///tmp/echo.sock", -1, $errno, $errstr);
if (!$fp) {
   return "ERROR: $errno - $errstr<br />\n";
} else {
   $out = fread($fp, 8192);
   fwrite($fp, "Hello World <3");
   $out2 = fread($fp, 8192);
   fclose($fp);
   echo  $out; // That code is in function.
   echo  $out2; // That code is in function.
}
?>
