<?php/* Description: FlashPaper文档转换,转换可打印的文档为FLASH格式并保存转换的相关信息到log_swfread表 * 使用FlashPaper服务需求 1. 运行在Windows(xp/2003)服务器下 2. 能调用系统命令exec 3. 调用的文件目录必须可读可写 4. 需要转换的文件类型，服务器必须安装相应的转换软件pdf安装 pdf 9.0, office安装2007,且必须是正版 5. 服务器需要支持虚拟打印机功能 6. 服务器的内容要足够大，最少4GB 7. 在系统管理-站点管理-设置网站URL和访问URL一致 * 测试FlashPaer 1.运行初始化中 初始化.bat文件 无任何错误即可(xp/2003) 2.查看打印机文档中是否有打印机FlashPaer 3.运行FlashPrinter.exe直接讲要转换的文件拖到此，如果能转换则软件安装无问题 * API调用方法 1. 同步调用 -支持多文件同时转换，不支持执行时间检测和转换状态检测 $flashPaper = A('Api.FlashPaper'); $flashPaper->convertFile($uploadlist); 2. 异步调用 -多文件上传需调用多次,支持执行时间检测和转换状态更新 $url = $this->config['site_url'].'Api/FlashPaper/convertFile'; foreach($uploadList as $data){ post($url,$data); } * 注意 1. 多文件同时转换 - FlashPaper产生多个独立的进程,转换完毕后自动关闭经常和被调用的程序(尚未支持) 2. 使用pptx/docx/xlsx转换速度快于2003格式 * 保持转换信息 - 系统默认保存转换的文件名称,文件大小,文件类型,转换后保持地址,转换时间,转换运行时间和转换失败的错误信息 - 默认保存的数据库表是log_swfread 保存的方式是execSaveInfo*/class FlashPaperAction extends Action{ public $flashpaper_url = '/Public/FlashPaper/FlashPrinter.exe'; // 应用程序路径 public $allow_file_ext = 'doc|docx|ppt|pptx|xls|xlsx|pdf|jpg|bmp|gif|png|txt'; // 允许转换的文件格式(可打印的文件) public $swf_savepath = '/Data/swfscorce/'; // SWF保存虚拟路径 public $time_limit = 1000; // 程序最大运行时间 private $socket = false; // 是否socket请求 private $scorce_file_path; // 上传文件物理路径 private $scorce_save_path; // 上传文件的保存路径 private $score_file_name; // 上传文件保存名称 private $scorce_file_ext; // 上传文件扩展名 private $scorce_file_size; // 文件大小 private $exec_error; // 转换文件错误提示 private $exec_start_time; // 转换开始时间 private $exec_end_time; // 转换结束时间 private $scorce_attch_id; // 附件信息ID号 private $swf_file_path = ''; // 转换swf文件保存物理路径 public function test(){ // 测试各种格式的文件转换 // 支持的文件: txt pdf ppt pptx jpg gif png bmp xls // 正在测试的文件: docx,xlsx,rtf pps pot doc $command = 'D:/yjoa/Public/FlashPaper/FlashPrinter.exe -o D:/yjoa/Data/swfScorce/201110/1.docx.swf D:/yjoa/Data/flashpaper/201110/1.xlsx'; $command = str_replace("/","\\",$command); $exec_start_time = $this->exectime(); exec($command, $return_array); $exec_end_time = $this->exectime(); echo 'Execue Time:'.round($exec_end_time - $exec_start_time, 6).'<br/>'; echo $command; } // 转换DEMO页面 public function _empty() { $fconfig = F('Config'); $upload_allow_ext = ''; $upload_allow_desc = ''; $upload_allow_extsarr = explode(',', $fconfig['upload_allow_exts']); foreach ($upload_allow_extsarr as $v) { $upload_allow_ext = $upload_allow_ext.
