我正在尝试让 perl 生产者与 ActiveMq 交谈。请找到我尝试过的代码。它给了我一个错误 “* Net::STOMP::Client::IO::receive_data(): cannot sysread(): EOF”**

调试错误后，$stomp->connect(); 请让我知道为什么此时出现此错误...我无法在线找到有关此问题的太多帮助..

提前致谢

我试图远程登录到我试图连接的 url。首先它正在连接，最后它是一些错误消息，如下所示：

CacheEnabledSizePrefixDisabled MaxInactivityDurationInitalDelay'TcpNoDelayEnabledMaxInactivityDurationu0TightEncodingEnabledStackTraceEnabledPuTTY
Connection closed by foreign host.

这意味着连接正在关闭。

这些是我怀疑有错误的代理日志：

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因该错误而失败。

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。
