Question

我在Laravel中编写了一个函数，用于使用用户提供的服务器凭据来测试SFTP连接。此功能运行良好，并显示有关连接状态的适当消息。

    var timeLeft = 3;
    var videoCounter = 2;
    var videoText = 2;
    var elem = document.querySelector('.countdown-content__count');
    var timerId;

    function countdown() {
      if (timeLeft == 0) {
        clearTimeout(timerId);
        $(".countdown-content__timer").fadeOut();
        $(".video-wrapper span").fadeOut();
        var playPromise = $("#video")[0].play();
      } else {
        elem.innerHTML = timeLeft;
        timeLeft--;
      }
    }

    function practiceShot(){
      setTimeout(function(){
        $(".countdown-content__head").slideUp(1000, function(){
              $(".countdown-content__timer").css({
                  opacity: 0,
                  display: 'inline-block'     
              }).animate({opacity:1},600);
              timerId = setInterval(countdown, 1000);
              countdown();
            });
          }, 2000);
    }
    practiceShot();
    document.getElementById('video').addEventListener('ended', function() {
        if (videoCounter == 0) {
            return;
        }
        document.getElementsByClassName("countdown-content__head")[0].innerHTML = "<span>Practice Shot </span>" + videoText;
        videoText++;
        videoCounter--;
        timeLeft = 3;
        elem.innerHTML = "";
        $(".countdown-content__timer").fadeIn();
        $(".video-wrapper span").fadeIn();
        $(".countdown-content__head").slideDown(1000, function(){
              $(".countdown-content__timer").css({
                  opacity:1,
                  display: 'inline-block'     
              }).animate({opacity:0},600);
        });
        practiceShot();
    }, false);

当用户提供无效的主机时，发生内部服务器错误。因此，我无法在返回的消息中显示消息。

如何获取此函数的正确错误消息？

示例（同时提供实际凭据）

.my_section_noload ALIGN(32) (NOLOAD) :
{
  *(.my_section)
} > MEMORY_1

内部服务器错误（输入错误的主机名或IP时）

public function testConnection(Request $request)
{
    $data = $request->all();
    $this->protocol = $data['protocol'];
    $this->host = $data['domain_name'];
    $this->username = $data['username'];
    $this->password = $data['password'];
    $this->port = $data['port'];
    $returnData = $this->checkFtp();
    return response()->json(['status' => true, 'connectionStatus' => $returnData]);
}

public function checkFtp()
{
    // Variable initialization
    $returnData = 'success';

    // SFTP connection test
    if ($this->protocol === 'sftp') {
        $sftp = new SFTP($this->host, $this->port, $this->timeout);
        if ($sftp) {
            if (!$sftp->login($this->username, $this->password)) {
                $returnData = 'Unable to login to the SFTP server';
            }
        } else {
            $returnData = 'Unable to connect to SFTP server';
        }
    }
}

更新：我通过添加try-catch重写了该函数，但仍然出现相同的错误...

{  
   "status":true,
   "connectionStatus":"success"
}

我认为您可以像下面的那样在subscribe（）中处理此问题。 500内部错误消息将显示为“错误”。只需控制台该“错误”即可查看消息

this.service.functionname(this.form.value).subscribe(data => {
    console.log(data);
}, error => {
    console.log(error);
});
