基于THINKPHP5 使用webuploader 大文件分片上传合并

今天用到大文件上传，使用了百度的webuploader分片上传

首先引入JQ,以及webuploader插件文件 css及js

<script src="/public/others/jquery.js"></script>
<script src="/public/webuploader/webuploader.js"></script>
<link rel ="slylesheet" type="text/css" href="/public/webuploader/webuploader.css">

　　html代码部分

<div class="demo">
    <div id="uploadfile">
        <!--用来存放文件信息-->
        <div id="the_2655" class="uploader-list"></div>
        <div class="form-group form-inline">
            <div id="pick_2655" style="float:left">选择文件</div>  
            <button id="Btn_2655" class="btn btn-default" style="padding: 5px 10px;border-radius: 3px;">开始上传</button>
        </div>
    </div>
</div>

直接使用uploadfiles方法，如下:

	
uploadfiles(2655,"files");

　　封装JS函数

//上传文件函数
//ids唯一ID
//folder文件保存目录
function uploadfiles(ids,folder) {
    $(function(){
        var $list = $("#the_"+ids);
            $btn = $("#Btn_"+ids);
        var uploader = WebUploader.create({
          resize: false, // 不压缩image
          swf: '__PUBLIC__/ueditor/third-party/webuploader/uploader.swf', // swf文件路径
          server: '{:url("admin/upload/uploadFile")}', // 文件接收服务端。
          pick: "#pick_"+ids, // 选择文件的按钮。可选
          chunked: true, //是否要分片处理大文件上传
          chunkSize:5*1024*1024, //分片上传，每片2M，默认是5M
          //fileSizeLimit: 6*1024* 1024 * 1024,    // 所有文件总大小限制 6G
          fileSingleSizeLimit: 10*1024* 1024 * 1024,    // 单个文件大小限制 5 G
          formData: {
                folder:folder  //自定义参数
          }
          //auto: false //选择文件后是否自动上传
         // chunkRetry : 2, //如果某个分片由于网络问题出错，允许自动重传次数
          //runtimeOrder: 'html5,flash',
          // accept: {
          //   title: 'Images',
          //   extensions: 'gif,jpg,jpeg,bmp,png',
          //   mimeTypes: 'image/*'
          // }
        });
        // 当有文件被添加进队列的时候
        uploader.on( 'fileQueued', function( file ) {
            $list.append( '<div id="' + file.id + '" class="item">' +
                '<h4 class="info">' + file.name + '</h4>' +
                '<p class="state">等待上传...</p>' +
            '</div>' );
        });
        // 文件上传过程中创建进度条实时显示。
        uploader.on( 'uploadProgress', function( file, percentage ) {
            var $li = $( '#'+file.id ),
                $percent = $li.find('.progress .progress-bar');
 
            // 避免重复创建
            if ( !$percent.length ) {
                $percent = $('<div class="progress progress-striped active">' +
                  '<div class="progress-bar" role="progressbar" style=" 0%">' +
                  '</div>' +
                '</div>').appendTo( $li ).find('.progress-bar');
            }
 
            $li.find('p.state').text('上传中');
 
            $percent.css( 'width', percentage * 100 + '%' );
        });
        // 文件上传成功
        uploader.on( 'uploadSuccess', function( file,response) {
            $( '#'+file.id ).find('p.state').text('已上传');
            $list.append('<input type="hidden" name="'+ids+'" value="'+response.filePath+'" />');
            //alert(response.filePath);
        });
 
        // 文件上传失败，显示上传出错
        uploader.on( 'uploadError', function( file ) {
            $( '#'+file.id ).find('p.state').text('上传出错');
        });
        // 完成上传完
        uploader.on( 'uploadComplete', function( file ) {
            $( '#'+file.id ).find('.progress').fadeOut();
        });
 
        $btn.on('click', function () {
            if ($(this).hasClass('disabled')) {
                return false;
            }
            uploader.upload();
            // if (state === 'ready') {
            //     uploader.upload();
            // } else if (state === 'paused') {
            //     uploader.upload();
            // } else if (state === 'uploading') {
            //     uploader.stop();
            // }
        });
    });
}
