[ASP.net教程]在禅道中实现WORD等OFFICE文档转换为PDF进行在线浏览


条件:

  1. 安装好禅道的服务器
  2. 能直接浏览PDF的浏览器(或通过 安装插件实现 )
  3. 文档转换服务程序(建议部署在另一台服务器上)

  

实现 原理:

  1. 修改禅道的文件预览功能(OFFICE文档其使用的是下载打开方式)为向转换服务请求PDF
  2. 转换服务收到URL后,下载该文件并调用后台服务转换为PDF,向请求者返回PDF
  3. 禅道内置的预览PDF功能直接请求浏览器预览PDF

  

需要修改的文件及内容

xampp\zentao\module\file\control.php

xampp\zentao\module\file\view\printfiles.html.php

xampp\zentao\module\group\lang\resource.php

xampp\zentao\module\file\lang\zh-cn.php

  

control.php

  

增加方法

  

public function cloudview($fileID, $mouse = '')

{

$file = $this->file->getById($fileID);

  

/* Judge the mode, down or open. */

$mode = 'view';

$fileTypes = 'txt|jpg|jpeg|gif|png|bmp|

if(stripos($fileTypes, $file->extension) !== false and $mouse == 'left') $mode = 'open';

        if($mode == 'open')

{

if(file_exists($file->realPath))$this->locate($file->webPath);

$this->app->triggerError("The file you visit $fileID not found.", __FILE__, __LINE__, true);

}

        else

if(file_exists($file->realPath))

{

$fileName = $file->title . '.' . $file->extension;

                $fileData = file_get_contents($file->realPath);

                $md5data=md5( $fileData);

$this->locate( 'http://192.168.118.136:9345/?url=' . common::getSysURL() . $file-> webPath . '&' . 'fileName=' . $fileName . '&' . 'md5=' . $md5data );

}

else

{

$this->app->triggerError("The file you visit $fileID not found.", __FILE__, __LINE__, true);

}

  

}

  

  

printfiles.html.php

  

修改方法downloadFile

新增方法viewFile

增加超链接指向

function downloadFile(fileID)

{

if(!fileID) return;

var sessionString = '<?php echo $sessionString;?>';

var url = createLink('file', 'cloudview', 'mfileID=' + fileID + '&mouse=left&mode=open') + sessionString;

      

window.open(url, '_blank');

return false;

}

  

function viewFile(fileID)

{

if(!fileID) return;

var sessionString = '<?php echo $sessionString;?>';

var url = createLink('file', 'cloudview', 'mfileID=' + fileID + '&mouse=left&mode=open') + sessionString;

       

window.open(url, '_blank');

return false;

}

  

增加链接

  

$fileTitle = "<li class='list-group-item'><i class='icon-file-text text-muted icon'></i> &nbsp;" . $file->title .'.' . $file->extension;

echo html::a($this->createLink('file', 'download', "fileID=$file->id") . $sessionString, $fileTitle, '_blank', "onclick='return viewFile($file->id)'");

echo "<span class='right-icon'>";

         common::printLink('file', 'download', "fileID=$file->id", "<i class='icon-download'></i>", '', "class='edit btn-icon' title='{$lang->file->download}'");

common::printLink('file', 'edit', "fileID=$file->id", "<i class='icon-pencil'></i>", '', "class='edit btn-icon' title='{$lang->file->edit}'");

if(common::hasPriv('file', 'delete')) echo html::a('###', "<i class='icon-remove'></i>", '', "class='btn-icon' onclick='deleteFile($file->id)' title='$lang->delete'");

echo '</span>';

echo '</li>';

  

resource.php

  

$lang->resource->file = new stdclass();

$lang->resource->file->download = 'download';

$lang->resource->file->cloudview = 'cloudview';

$lang->resource->file->edit = 'edit';

  

zh-cn.php

  

$lang->file->uploadImages = '多图上传';

$lang->file->cloudview = '云预览';

$lang->file->download = '下载附件';
