ThinkPHP6使用百度Web Uploader实现视频分片上传

WebUploader是由Baidu WebFE(FEX)团队开发的一个简单的以HTML5为主,FLASH为辅的现代文件上传组件。在现代的浏览器里面能充分发挥HTML5的优势,同时又不摒弃主流IE浏览器,沿用原来的FLASH运行时,兼容IE6+,iOS 6+, android 4+。两套运行时,同样的调用方式,可供用户任意选用。


采用大文件分片并发上传,极大的提高了文件上传效率。

前端代码:

<div class="layui-form-item">
	<label class="layui-form-label"><span class="x-red">*</span>视频</label>
	<div id="uploadfile" class="layui-input-inline">
		<div id="the_2655" class="uploader-list"></div>
		<div id="pick_2655">选择文件</div>  
		<a id="Btn_2655" class="layui-btn  layui-btn-primary">开始上传</a>
	</div>
</div>

样式:

 <style>
.webuploader-container {
display: inline-block;
float: left;
margin-right: 10px;
position: relative;
}
.webuploader-element-invisible {
position: absolute !important;
clip: rect(1px 1px 1px 1px); /* IE6, IE7 */
clip: rect(1px,1px,1px,1px);
}
.webuploader-pick {
position: relative;
display: inline-block;
cursor: pointer;
background: #00b7ee;
padding: 10px 15px;
color: #fff;
text-align: center;
border-radius: 3px;
overflow: hidden;
}
.webuploader-pick-hover {
background: #00a2d4;
}

.webuploader-pick-disable {
opacity: 0.6;
pointer-events:none;
}


</style>

js代码:

<script>
	uploadfiles(2655,"files");
	//上传文件函数
	//ids唯一ID
	//folder文件保存目录
	function uploadfiles(ids,folder) {
		$(function(){

			});
			// 当有文件被添加进队列的时候

			// 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="width: 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="video" value="'+response.filePath+'" />');
				console.log(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();
