上传30秒后,使用PHP上传的Dropzone.js失败

Question

我正在尝试将"大"文件上传到我的应用程序.用户必须能够上传小于200MB的视频文件,但似乎服务器在4MB或30秒后丢弃连接并且上载失败.

我已经在我的php.ini文件中设置了所有参数:

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

当我上传2MB @ 1Mbps/s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)

可以通过php_info访问live 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";

以下是处理上传的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();

}

所以一切似乎都没问题,但服务器在出错之后断开连接(我认为与PDO查询无关导致2MB的较小文件将起作用).

你能帮忙找出问题所在吗？

编辑做了一些测试我发现脚本在执行30秒时完全丢失,我试图添加set_time_limit(0);到脚本顶部但没有再改变

XHR超时中的问题是指ajax调用配置.

为避免这种情况,必须timeout: 180000在DropZone.jsinit参数中放入(或以ms为单位).

$("#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");
     }
});

30 seconds上传文件时不会导致超时DropZone.js.

UPDATE

作为@Brendon缪尔报道,您还可以插入0作为timeout禁用超时.

DropZone.js文档报告默认超时为0,这是不正确的,默认超时为30秒.值为0将禁用超时.
