Dropzone.js 上传 PHP 上传 30 秒后失败

Dropzone.js upload with PHP failed after 30 seconds upload

我正在尝试将 "large" 文件上传到我的应用程序。用户必须能够上传最小小于 200MB 的视频文件,但服务器似乎在 4MB 或 30 秒后断开连接并且上传失败。

我已经在 php.ini 文件中设置了所有参数,如下所示:

max_input_time = 320
max_execution_time = 320
max_file_uploads = 20
memory_limit = 512M
post_max_size = 201M
upload_max_filesize = 200M

当我以 1Mbps/s 的速度上传 2MB 的文件时一切正常(我不知道是否与文件大小或传输时间有关)

可在 php_info

访问实时 php_info() 文件

虽然这里是DropZone.js conf:

$("#dZUpload").dropzone({
     url: "/ajax/admin/admin.acceptVideo.php",
     maxFilesize: 209715200,
     acceptedFiles: "video/*",
     addRemoveLinks: true,
     dataType: "HTML",
     data: { id: '' },
     success: function (file, response, data) {
         var imgName = response;
         file.previewElement.classList.add("dz-success");
         $('#form_video').val(imgName);
     },
     error: function (file, response) {
     file.previewElement.classList.add("dz-error");
     }
});
Dropzone.autoDiscover = false;
Dropzone.prototype.defaultOptions.dictRemoveFile = "Rimuovi file";
Dropzone.prototype.defaultOptions.dictCancelUpload = "Annulla";

这是处理上传的 PHP 脚本:

<?php
require_once '../db.config.php';

header('Content-Type: text/plain; charset=utf-8');

ini_set('upload_max_filesize', '200M');
ini_set('post_max_size', '201M');
ini_set('max_input_time', 320);
ini_set('memory_limit', '256M'); 


try {
    if (
        !isset($_FILES['file']['error']) ||
        is_array($_FILES['file']['error'])
    ) {
        throw new RuntimeException('Invalid parameters.');
    }

    switch ($_FILES['file']['error']) {
    case UPLOAD_ERR_OK:
        break;
    case UPLOAD_ERR_NO_FILE:
        throw new RuntimeException('No file sent.');
        break;
    case UPLOAD_ERR_INI_SIZE:
        break;
    case UPLOAD_ERR_FORM_SIZE:
        throw new RuntimeException('Exceeded filesize limit.');
        break;
    default:
        throw new RuntimeException('Unknown errors.');
        break;
}

    // check filesize. 
    if ($_FILES['file']['size'] > 209715200) {
        throw new RuntimeException('Exceeded filesize limit.');
    }

    // Check MIME Type.
    $finfo = new finfo(FILEINFO_MIME_TYPE);
    if (false === $ext = array_search(
            $finfo->file($_FILES['file']['tmp_name']),
            array(
                'mp4' => 'video/mp4',
                'mov' => 'video/mov',
                'avi' => 'video/avi',
            ),
            true
        )) {
        throw new RuntimeException('Invalid file format.');
    }

    // name uniquely.
    $fileName = sha1_file($_FILES['file']['tmp_name']);
    if (!move_uploaded_file($_FILES['file']['tmp_name'], sprintf('/var/www/html/beta.vedocompro.it/web/webtemp/%s.%s', $fileName, $ext ))) {
        throw new RuntimeException('Failed to move uploaded file.');
    }

    try {

        $PDO = new PDO('mysql:host=' . $DB_HOST . ';dbname=' . $DB_NAME,$DB_USER,$DB_PASS);
        $insert = $PDO->prepare("INSERT INTO `videos` (`id`, `aid`, `accepted`, `uid`, `dir`) VALUES (NULL, '0', '0', '0', $fileName);");
        $insert->execute();

        echo $fileName;

    } catch(PDOException $exception) {
        echo $exception;
    }



} catch (RuntimeException $e) {

    echo $e->getMessage();

}

所以一切似乎都正常,但服务器在出现错误后断开连接(我不认为与 PDO 查询有关,因为 2MB 的较小文件可以工作)。

能否请您帮助确定问题所在?

EDIT 做一些测试我发现脚本恰好在执行 30 秒时下降,我尝试在脚本顶部添加 set_time_limit(0);但什么也没有改变

问题出在参考 ajax 调用配置的 XHR 超时中。

为避免这种情况,必须在 DropZone.js 初始化参数中放入 timeout: 180000(或您想要的毫秒数)。

$("#dZUpload").dropzone({
     url: "/ajax/admin/admin.acceptVideo.php",
     maxFilesize: 209715200,
     acceptedFiles: "video/*",
     addRemoveLinks: true,
     dataType: "HTML",
     timeout: 180000,
     success: function (file, response, data) {
         // Do things on Success
     },
     error: function (file, response) {
     file.previewElement.classList.add("dz-error");
     }
});

这不会导致 30 seconds 使用 DropZone.js 上传文件时超时。

更新

正如@Brendon Muir 报道的那样,您还可以将 0 作为 timeout 插入以禁用超时。

The DropZone.js Documentation reports that the default timeout is 0, that's incorrect, the default timeout is 30 seconds. A value of 0 will disable the timeout.

我意识到这个问题有点陈旧,但我在捕获超时行为时遇到了问题,并发现了这个解决方案,而不是在发送函数上捕获超时,如下所示:

$("#dZUpload").dropzone({
     url: "/ajax/admin/admin.acceptVideo.php",
     maxFilesize: 209715200,
     acceptedFiles: "video/*",
     addRemoveLinks: true,
     dataType: "HTML",
     data: { id: '' },
     success: function (file, response, data) {
         var imgName = response;
         file.previewElement.classList.add("dz-success");
         $('#form_video').val(imgName);
     },
     error: function (file, response) {
         file.previewElement.classList.add("dz-error");
     },
     //Called just before each file is sent
     sending: function(file, xhr, formData) {
         //Execute on case of timeout only
         xhr.ontimeout = function(e) {
             //Output timeout error message here
             console.log('Server Timeout');

         };
     }
});
