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
