1.新建上传页面
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<!--引入CSS-->
<link rel="stylesheet" type="text/css" href="__ROOT__/public/webuploader/webuploader.css">
<title>Document</title>
</head>
<body>
<div id="uploader" class="wu-example">
<!--用来存放文件信息-->
<div id="thelist" class="uploader-list"></div>
<div class="btns">
<div id="picker">选择文件</div>
<button id="ctlBtn" class="btn btn-default">开始上传</button>
</div>
</div>
</body>
</html>
<!--引入JS-->
<script src="https://code.jquery.com/jquery-3.4.1.min.js"></script>
<script type="text/javascript" src="__ROOT__/public/webuploader/webuploader.min.js"></script>
<script>
let uploader = new WebUploader.Uploader({
// swf文件路径
swf: ‘__ROOT__/public/webuploader/Uploader.swf‘,
// 文件接收服务端。
server: ‘__ROOT__/public/upload.php‘,
// 选择文件的按钮。可选。
// 内部根据当前运行是创建，可能是input元素，也可能是flash.
pick: ‘#picker‘,
// 分片上传。
chunked: true,
chunkSize: 2 * 1024 * 1024,
// 不压缩image, 默认如果是jpeg，文件上传前会压缩一把再上传！
resize: false
});
let $list = $(‘#thelist‘);
// 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 ) {
let $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 + ‘%‘ );
});
//开始上传
$(‘#ctlBtn‘).click(function () {
uploader.upload();
});
uploader.on( ‘uploadSuccess‘, function( file, response ) {
if (response.status) {
$( ‘#‘+file.id ).find(‘p.state‘).text(‘已上传‘);
} else {
$( ‘#‘+file.id ).find(‘p.state‘).text(response.msg);
}
});
uploader.on( ‘uploadError‘, function( file ) {
$( ‘#‘+file.id ).find(‘p.state‘).text(‘上传出错‘);
});
uploader.on( ‘uploadComplete‘, function( file ) {
$( ‘#‘+file.id ).find(‘.progress‘).fadeOut();
});
</script>
2.下载 webuploader插件
3.服务器 处理上传文件
<?php //储存分片 服务器目录 $tmp_dir = ‘./upload/tmp_chunk/‘ . $_REQUEST[‘name‘] . ‘/‘; if (! is_dir($tmp_dir)) { mkdir($tmp_dir, 0777, true); } move_uploaded_file($_FILES[‘file‘][‘tmp_name‘], $tmp_dir . $_REQUEST[‘chunk‘]); //合并分片 结果存储目录 if ($_REQUEST[‘chunk‘] == $_REQUEST[‘chunks‘] - 1) { //最后一个分片 $target_file = ‘./upload/results/‘; if (! is_dir($target_file)) { mkdir($target_file, 0777, true); } $target_file .= $_REQUEST[‘name‘]; $handle = fopen($target_file, ‘x+‘); for ($i=0; $i<$_REQUEST[‘chunks‘]; $i++) { fwrite($handle, file_get_contents($tmp_dir . $i)); } fclose($handle); } $msg = [ ‘$_FILES‘ => json_encode($_FILES), ‘$_REQUEST‘ => json_encode($_REQUEST), ]; echo json_encode([‘status‘ => 1, ‘msg‘ => json_encode($msg)]);
4.打开页面 上传文件 测试。
