在禪道中實現WORD等OFFICE文檔轉換爲PDF進行在線瀏覽

條件：

1. 安裝好禪道的服務器
2. 能直接瀏覽PDF的瀏覽器（或經過 安裝插件實現 ）
3. 文檔轉換服務程序（建議部署在另外一臺服務器上）

   

實現 原理：

1. 修改禪道的文件預覽功能（OFFICE文檔其使用的是下載打開方式）爲向轉換服務請求PDF
2. 轉換服務收到URL後，下載該文件並調用後臺服務轉換爲PDF，向請求者返回PDF
3. 禪道內置的預覽PDF功能直接請求瀏覽器預覽PDF

}

        else

修改方法downloadFile

新增方法viewFile

增長超連接指向

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

        

window.open(url, '_blank');

return false;

}

   

增長連接

   

$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)'");
