Blueimp PHP和jQuery文件上传分块在第一个块之后失败

Question

我在Blueimp中实现分块功能时遇到了麻烦。 我需要分块功能将大文件上传到我的服务器，但我无法提升post_max_size和upload_max_filesize。 该文档声明它默认支持，只需要下面的代码来激活它。

$('#fileupload').fileupload({
    maxChunkSize: 10000000 // 10 MB
});

哪个公平并没有错，但是在上传第一个块之后上传失败了。

文档中是否还有其他内容无法成功使用？

我使用的代码与演示版Basic Plus完全相同，但无论如何我都将它包含在下面

的jQuery

/*jslint unparam: true, regexp: true */
/*global window, $ */
$(function () {
'use strict';
// Change this to the location of your server-side upload handler:
var url = window.location.hostname === 'example.com' ? '//classes/' : 'classes/',
    uploadButton = $('<button/>')
        .addClass('btn btn-primary')
        .prop('disabled', true)
        .text('Processing...')
        .on('click', function () {
            var $this = $(this),
                data = $this.data();
            $this
                .off('click')
                .text('Abort')
                .on('click', function () {
                    $this.remove();
                    data.abort();
                });
            data.submit().always(function () {
                $this.remove();
            });
        });
$('#fileupload').fileupload({

    url: url,
    dataType: 'json',
    autoUpload: false,
    //multipart: false,
    acceptFileTypes: /(\.|\/)(mp4|mpeg4)$/i,
    maxFileSize: 2000000000, // 2 GB
    maxChunkSize: 2000000, // 2 MB
    // Enable image resizing, except for Android and Opera,
    // which actually support image resizing, but fail to
    // send Blob objects via XHR requests:

        progress + '%'
    );

            var link = $('<a>')
                .attr('target', '_blank')
                .prop('href', file.url);
            $(data.context.children()[index])
                .wrap(link);
        } else if (file.error) {
            var error = $('<span class="text-danger"/>').text(file.error);

HTML表单

<!-- The fileinput-button span is used to style the file input field as button -->
<span class="btn btn-success fileinput-button">
    <i class="glyphicon glyphicon-plus"></i>
    <span>Add files...</span>
    <input id="fileupload" class="adminFields" type="file" name="files[]" multiple>
</span>
