我使用 Chilkat php 扩展。而且我注意到 chilkat 方法 Connect 永远挂起。put_ReadTimeout()并且put_ConnectTimeout()不修复它。

我也通过 ssh 使用它。代码很简单，如下所示：

// $this->imap is a CKImap class

$this->imap->put_ConnectTimeout(10);
$this->imap->put_Ssl(true);
$this->imap->put_PeekMode(true);
$this->imap->put_Utf8(true);
$this->imap->put_VerboseLogging(true);
$this->imap->put_DebugLogFilePath('/var/www/logs/log_chilkat.txt');
$this->imap->SshOpenTunnel($proxy->ip, $proxy->port);
$this->imap->SshAuthenticatePw($proxy->username,$proxy->password);

// At this point it hangs forever
$this->imap->Connect($account->imap_server);
$this->imap->login($account->email, $account->password);

我错过了任何无用的条件和其他代码。它是工作代码，有时它挂在 Connect 行。也许问题出在 SSH 中，也许 SSH 挂起？

如何解决？我还没有找到用 chilkat 函数解决的方法。另外我不想使用信号来停止 fetch 函数的执行。

我已经想通了。我做了很多测试，它挂在下一行： $this->imap->Connect($account->imap_server);

Chilkat 详细日志如下：

日志结束于Received EOF on SSH channel.如你所见，我使用最后一个 Chilkat 版本。我的环境是 Ubuntu 服务器 18.04 64bit。PHP 7.2.2 ZTS。我在 Windows 上也遇到了同样的问题。

！！！同样重要的一点是，应用程序运行在多线程中，45 个线程。每个线程都有自己的 CkImap 对象并通过 ssh 连接到 imap。有时一些线程挂在连接到 imap 点。

这个挂怎么解决？

我找到了一些方法put_AbortCurrent。我可以用它来中止 Connect 方法吗？在我看来，下一个代码必须在连接超时后中止连接：

        $this->imap->put_AbortCurrent(true);
        $connectedToImap = $this->imap->Connect($account->imap_server);
        $this->imap->put_AbortCurrent(false);

使用 VerboseLogging 和 DebugLogFilePath 找出发生了什么。重现带有这些属性集的挂起。然后查看日志文件以了解挂起的位置（请参见下面的示例代码）。

此外，使用最新版本的 Chilkat 进行测试。如果您使用的是旧版本，也许很久以前就已经修复了。发行说明可在以下网址获得： http: //cknotes.com/chilkat-v9-5-0-78-release-notes/


    $imap = new CkImap();

    $imap->put_VerboseLogging(true);
    $imap->put_DebugLogFilePath('someDir/imapDebugLog.txt');
    $imap->put_ReadTimeout(10);

    // ...

    // Some UID...
    $msgId = 123;
    $bUid = true;
    $strMime = $imap->fetchSingleAsMime($msgId,$bUid);
    if ($imap->get_LastMethodSuccess() != true) {
        print $imap->lastErrorText() . "\n";
        exit;
    }

    print $strMime . "\n";
