脚本宝典收集整理的这篇文章主要介绍了关于在TP中使用webupload切片上传文件与CI框架中切片上传文件，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
一、在TP框架中使用切片上传
<head> <link href="/webuploader/webuploader.css" rel="stylesheet"> </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> <script tyPE="text/javascript" src="/webuploader/webuploader.js"></script> <script type="text/javascript"> VAR $btn = $(‘#ctlBtn‘); var uploader = WebUploader.create({ // swf文件路径 swf: ‘/webuploader/Uploader.swf‘,// 文件接收服务端。 server: ‘uploaDFile‘,// 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‘,chunked: true,//是否要分片处理大文件上传 chunkSize:2*1024*1024,//分片上传，每片2M，默认是5M fileSingleSizeLimIT: 10*1024* 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 }); // 当有文件被添加进队列的时候 uploader.on( ‘fileQueued‘,function( file ) { var $list = $(‘#thelist‘); $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="width: 0%">‘ + ‘</div>‘ + ‘</div>‘).appendTo( $li ).find(‘.progress-bar‘); } $li.find(‘p.state‘).text(‘上传中‘); $percent.css( ‘width‘,percentage * 100 + ‘%‘ ); }); uploader.on( ‘uploadSuccess‘,function( file ) { $( ‘#‘+file.id ).find(‘p.state‘).text(‘已上传‘); }); 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(); }); $btn.on(‘click‘,function(){ if ($(this).hasClass(‘disabled‘)) { return false; } uploader.upload(); }); </script> </body>
public function sourceSave(){ header("Expires: Mon,26 Jul 1997 05:00:00 GMT"); header("Last-Modified: " . gmdate("D,d M Y H:i:s") .

DIRECTORY_SEPARATOR . $fileName; // $uploadPath = $uploadDir . DIRECTORY_SEPARATOR . $fileName; // Chunking might be enabled $chunk = isset($_REQUEST["chunk"]) ? intval($_REQUEST["chunk"]) : 0; $chunks = isset($_REQUEST["chunks"]) ? intval($_REQUEST["chunks"]) : 1; // Remove old temp files if ($cleanupTargetDir) { if (!is_dir($targetDir) || !$dir = opendir($targetDir)) { die(‘{"jsonrpc" : "2.0","error" : {"code": 100,"message": "Failed to open temp directory111."},"id" : "id"}‘); } while (($file = readdir($dir)) !== false) { $tmpfilePath = $targetDir . DIRECTORY_SEPARATOR . $file; // If temp file is current file proceed to the next if ($tmpfilePath == "{$filePath}_{$chunk}.part" || $tmpfilePath == "{$filePath}_{$chunk}.parttmp") { continue; } // Remove temp file if it is older than the max age and is not the current file if (preg_match(‘/\.(part|parttmp)$/‘,$file) && (filemtime($tmpfilePath) < time() - $maxFileAge)) { unlink($tmpfilePath); } } closedir($dir); } // Open temp file if (!$out = fopen("{$filePath}_{$chunk}.parttmp","wb")) { die(‘{"jsonrpc" : "2.0","error" : {"code": 102,"message": "Failed to open output stream222."},"id" : "id"}‘); } if (!empty($_FILES)) { if ($_FILES["file"]["error"] || !is_uploaded_file($_FILES["file"]["tmp_name"])) { die(‘{"jsonrpc" : "2.0","error" : {"code": 103,"message": "Failed to move uploaded file333."},"id" : "id"}‘); } // Read binary input stream and append it to temp file if (!$in = fopen($_FILES["file"]["tmp_name"],"rb")) { die(‘{"jsonrpc" : "2.0","error" : {"code": 101,"message": "Failed to open input stream444."},"id" : "id"}‘); } } else { if (!$in = fopen("PHP://input","message": "Failed to open input stream555."},"id" : "id"}‘); } } while ($buff = fread($in,4096)) { fwrite($out,$buff); } fclose($out); fclose($in); rename("{$filePath}_{$chunk}.parttmp","{$filePath}_{$chunk}.part"); $index = 0; $done = true; for( $index = 0; $index < $chunks; $index++ ) { if ( !file_exists("{$filePath}_{$index}.part") ) { $done = false; break; } } if ($done) { $pathInfo = pathinfo($fileName); $hashStr = substr(md5($pathInfo[‘basename‘]),8,16); $hashName = time() . $hashStr . ‘.‘ .$pathInfo[‘extension‘]; $uploadPath = $uploadDir . DIRECTORY_SEPARATOR .$hashName; if (!$out = fopen($uploadPath,"wb")) { die(‘{"jsonrpc" : "2.0","message": "Failed to open output stream666."},"id" : "id"}‘); } //flock($hander,LOCK_EX)文件锁 if ( flock($out, LOCK_EX) ) { for( $index = 0; $index < $chunks; $index++ ) { if (!$in = fopen("{$filePath}_{$index}.part","rb")) { break; } while ($buff = fread($in,4096)) { fwrite($out,$buff); } fclose($in); unlink("{$filePath}_{$index}.part"); } flock($out, LOCK_UN); } fclose($out); $response = [ ‘success‘=>true,‘oldName‘=>$oldName,‘filePath‘=>$uploadPath,// ‘fileSize‘=>$data[‘size‘], ‘fileSuffixes‘=>$pathInfo[‘extension‘],//文件后缀名 // ‘file_id‘=>$data[‘id‘], ]; return json($response); } // Return Success JSON-RPC response die(‘{"jsonrpc" : "2.0","result" : null,"id" : "id"}‘); }
二、在CI框架中使用切片上传
（1）.这里直接写控制器里面的方法
public function uploadFile(){ header("Access-Control-Allow-origin:*"); //header("Access-Control-Allow-Credentials:true"); //header(‘Access-Control-Allow-Headers:x-requested-with,content-type‘); header("Expires: Mon,d M Y H:i:s") . " GMT"); header("Cache-Control: no-store,false); header("Pragma: no-cache"); // Support CORS // header("Access-Control-Allow-Origin: *"); // other CORS headers if any... if ($_SERVER[‘REQUEST_METHOD‘] == ‘OPTIONS‘) { exit; // finish preflight CORS requests here } if ( !empty($_REQUEST[ ‘debug‘ ]) ) { $random = rand(0,intval($_REQUEST[ ‘debug‘ ]) ); if ( $random === 0 ) { header("HTTP/1.0 500 Internal Server Error"); exit; } } // //var_dump($_REQUEST); // // header("HTTP/1.0 500 Internal Server Error"); // exit; // 5 minutes execution time @set_time_limit(5 * 60); $targetDir = ‘./uploads/yinshua/upload_tmp‘; $uploadDir = ‘./uploads/yinshua‘; $cleanupTargetDir = true; // Remove old files $maxFileAge = 5 * 3600; // Temp file age in seconds // Create target dir if (!file_exists($targetDir)) { @mkdir($targetDir); } // Create target dir if (!file_exists($uploadDir)) { @mkdir($uploadDir); } // Get a file name if (isset($_REQUEST["name"])) { $fileName = $_REQUEST["name"]; } elseif (!empty($_FILES)) { $fileName = $_FILES["file"]["name"]; } else { $fileName = uniqid("file_"); } $time = time(); $filePath = $targetDir . DIRECTORY_SEPARATOR . $fileName; $uploadPath = $uploadDir . DIRECTORY_SEPARATOR .$time. $fileName; // Chunking might be enabled $chunk = isset($_REQUEST["chunk"]) ? intval($_REQUEST["chunk"]) : 0; $chunks = isset($_REQUEST["chunks"]) ? intval($_REQUEST["chunks"]) : 1; // Remove old temp files if ($cleanupTargetDir) { if (!is_dir($targetDir) || !$dir = opendir($targetDir)) { die(‘{"jsonrpc" : "2.0","message": "Failed to open temp directory."},"id" : "id"}‘); } while (($file = readdir($dir)) !== false) { $tmpfilePath = $targetDir . DIRECTORY_SEPARATOR . $file; // If temp file is current file proceed to the next if ($tmpfilePath == "{$filePath}_{$chunk}.part" || $tmpfilePath == "{$filePath}_{$chunk}.parttmp") { continue; } // Remove temp file if it is older than the max age and is not the current file if (preg_match(‘/\.(part|parttmp)$/‘,$file) && (@filemtime($tmpfilePath) < time() - $maxFileAge)) { @unlink($tmpfilePath); } } closedir($dir); } // Open temp file if (!$out = @fopen("{$filePath}_{$chunk}.parttmp","message": "Failed to open output stream."},"id" : "id"}‘); } if (!empty($_FILES)) { if ($_FILES["file"]["error"] || !is_uploaded_file($_FILES["file"]["tmp_name"])) { die(‘{"jsonrpc" : "2.0","message": "Failed to move uploaded file."},"id" : "id"}‘); } // Read binary input stream and append it to temp file if (!$in = @fopen($_FILES["file"]["tmp_name"],"rb")) { die(‘{"jsonrpc" : "2.0","message": "Failed to open input stream."},"id" : "id"}‘); } } else { if (!$in = @fopen("PHP://input","id" : "id"}‘); } } while ($buff = fread($in,$buff); } @fclose($out); @fclose($in); rename("{$filePath}_{$chunk}.parttmp","{$filePath}_{$chunk}.part"); $index = 0; $done = true; for( $index = 0; $index < $chunks; $index++ ) { if ( !file_exists("{$filePath}_{$index}.part") ) { $done = false; break; } } if ( $done ) { if (!$out = @fopen($uploadPath,"id" : "id"}‘); } if ( flock($out, LOCK_EX) ) { for( $index = 0; $index < $chunks; $index++ ) { if (!$in = @fopen("{$filePath}_{$index}.part","rb")) { break; } while ($buff = fread($in,$buff); } @fclose($in); @unlink("{$filePath}_{$index}.part"); } flock($out, LOCK_UN); } @fclose($out); } $data = array( ‘jsonrpc‘=>"2.0",‘path‘ =>$uploadPath ); echo json_encode($data,true);die; // Return Success JSON-RPC response $uploadPath //die(‘{"jsonrpc" : "2.0","result" : $data,"id" : "id"}‘); }
