Question

我正在尝试与perl制作人交谈ActiveMq。请找到我尝试过的代码。它给了我一个错误“* Net :: STOMP :: Client :: IO :: receive_data（）：不能sysread（）：EOF”**

调试后错误发生在$stomp->connect(); 请让我知道为什么这个错误...我无法在网上找到这方面的帮助..

提前致谢

我试图telnet到我想要连接的网址。首先它是连接的，最后是一些错误信息，如下所示：

CacheEnabledSizePrefixDisabled MaxInactivityDurationInitalDelay'TcpNoDelayEnabledMaxInactivityDurationu0TightEncodingEnabledStackTraceEnabledPuTTY
Connection closed by foreign host.

这表示连接已关闭。

这些是代理日志，我怀疑有些错误：

代码：

#! /usr/bin/perl

use strict;
use warnings;

use Net::STOMP::Client;
my $stomp = Net::STOMP::Client->new(uri => "tcp://$url:$port");
my $peer = $stomp->peer();
  printf("connected to broker %s (IP %s), port %d\n",
      $peer->host(), $peer->addr(), $peer->port());
  $stomp->connect();
  printf("speaking STOMP %s with server %s\n",
      $stomp->version(), $stomp->server() || "UNKNOWN");
  printf("session %s started\n", $stomp->session());
  $stomp->disconnect();
  printf("session ended\n");

如果您告诉我们错误发生在哪一行，那会有所帮助，因为这会指出哪个调用失败了该错误。

Perl的STOMP库有一些非常错误的版本。确保您使用的是CPAN的最新版本，而不是系统上预装的旧版本。
