How do I convert RTF to PDF from my PHP web page using OpenOffice?
提问by user115487
My OS is Windows XP, and I'm using IIS 5.1 and PHP 5.2.9. I'm trying to call a PHP script from my PHP page in order to convert an RTF doc to a PDF, using OpenOffice. The script works just fine when I call it directly from the command line, but I'm not having any success getting the very same script to work when launched from my PHP web page.
我的操作系统是 Windows XP，我使用的是 IIS 5.1 和 PHP 5.2.9。我正在尝试从我的 PHP 页面调用 PHP 脚本，以便使用 OpenOffice 将 RTF 文档转换为 PDF。当我直接从命令行调用该脚本时，它工作得很好，但是当从我的 PHP 网页启动时，我没有成功地使完全相同的脚本工作。
When I call the script from my PHP page, the page hangs, eventually showing an error, and I've noted that I can see in the Task Manager where the soffice.bin and soffice.exe processes are running under my IIS user name.
当我从 PHP 页面调用脚本时，页面挂起，最终显示错误，我注意到我可以在任务管理器中看到 soffice.bin 和 soffice.exe 进程在我的 IIS 用户名下运行。
This is the error:
这是错误：
Fatal error: Uncaught exception 'com_exception' with message 'Failed to create COM object `com.sun.star.ServiceManager': Server execution failed ' in C:\WEB_ROOT\SoftwareContract\WordToPdf.php:14 Stack trace: #0 C:\WEB_ROOT\SoftwareContract\WordToPdf.php(14): com->com('com.sun.star.Se...') #1 C:\WEB_ROOT\SoftwareContract\Index.php(11): word2pdf('file:///C:/web_...', 'file:///C:/web_...') #2 {main} thrown in C:\WEB_ROOT\SoftwareContract\WordToPdf.php on line 14
I've double-checked permissions for my IIS user in these areas:
我已经在这些领域仔细检查了我的 IIS 用户的权限：
C:\PHP
C:\Program Files\OpenOffice.org 3
C:\Program Files\Java
C:\WEB_ROOT ---- location for my php code
In each case, my IIS user has these permissions: Read and Execute, List Folder Contents, Read. And in each case there are no "denys" checked to offset the permissions. I also gave the IIS user write permissions for the Web_Root folder where the php code resides.
在每种情况下，我的 IIS 用户都具有以下权限：读取和执行、列出文件夹内容、读取。并且在每种情况下都没有检查“拒绝”来抵消权限。我还授予 IIS 用户对 php 代码所在的 Web_Root 文件夹的写入权限。
This is the php which calls the conversion function, WordToPdf:
这是调用转换函数 WordToPdf 的 php：
<?php
require_once('WordToPdf.php');
$output_dir = 'C:/web_root/softwarecontract/';
$doc_file = 'C:/web_root/softwarecontract/testdoc.rtf';
$pdf_file = 'output.pdf';
$output_file = $output_dir . $pdf_file;
$doc_file = "file:///" . $doc_file;
$output_file = "file:///" . $output_file;
word2pdf($doc_file,$output_file);
?>
And this is WordToPdf.php:
这是 WordToPdf.php：
<?php
set_time_limit(0);
function MakePropertyValue($name,$value,$osm)
{
$oStruct = $osm->Bridge_GetStruct("com.sun.star.beans.PropertyValue");
$oStruct->Name = $name;
$oStruct->Value = $value;
return $oStruct;
}
function word2pdf($doc_url, $output_url)
{
//Invoke the OpenOffice.org service manager
$osm = new COM("com.sun.star.ServiceManager") or die ("Please be sure that OpenOffice.org is installed.\n");
//Set the application to remain hidden to avoid flashing the document onscreen
$args = array(MakePropertyValue("Hidden",true,$osm));
//Launch the desktop
$oDesktop = $osm->createInstance("com.sun.star.frame.Desktop");
//Load the .doc file, and pass in the "Hidden" property from above
$oWriterDoc = $oDesktop->loadComponentFromURL($doc_url,"_blank", 0, $args);
//Set up the arguments for the PDF output
$export_args = array(MakePropertyValue("FilterName","writer_pdf_Export",$osm));
//Write out the PDF
$oWriterDoc->storeToURL($output_url,$export_args);
$oWriterDoc->close(true);
}
?>
Are there any problems with my permissions, or any additional areas where I need to check permissions for the IIS user? Does anyone have an idea why IIS failed to create the COM object, if not a permissions issue?
我的权限是否有任何问题，或者我需要检查 IIS 用户权限的任何其他区域？如果不是权限问题，有没有人知道为什么 IIS 无法创建 COM 对象？
Thanks!!
谢谢！！

Yay!!!! With the help of a super-duper brainiac here at work, I now have a solution that actually WORKS! Forget all the code I posted earlier, I'm not using any of it anymore. If anyone else needs to convert word docs to PDF from PHP on IIS here's what will work:
好极了！！！！在工作中的超级傻瓜的帮助下，我现在有了一个真正有效的解决方案！忘记我之前发布的所有代码，我不再使用它们了。如果其他人需要在 IIS 上将 Word 文档从 PHP 转换为 PDF，则可以使用以下方法：
1) Install OpenOffice, of course
1）当然要安装OpenOffice
2) Go here:
http://www.artofsolving.com/opensource/pyodconverter, and download DocumentConverter.py
2）去这里：
http://www.artofsolving.com/opensource/pyodconverter，并下载 DocumentConverter.py
3) Place DocumentConverter.py in the same OpenOffice folder where soffice.exe resides, probably C:\Program Files\OpenOffice.org 3\program
3) 将 DocumentConverter.py 放在 soffice.exe 所在的同一个 OpenOffice 文件夹中，可能是 C:\Program Files\OpenOffice.org 3\program
4) Start OpenOffice as a service:
4) 将 OpenOffice 作为服务启动：
a)You can do this from the command line:
a) 您可以从命令行执行此操作：
soffice "-accept=socket,host=localhost,port=8100;urp;StarOffice.ServiceManager" -headless -norestore -nologo -nofirststartwizard
soffice "-accept=socket,host=localhost,port=8100;urp;StarOffice.ServiceManager" -headless -norestore -nologo -nofirststartwizard
b) Or follow the directions on this website and setup OpenOffice as a windows service with the proper parameters: http://www.artofsolving.com/node/10
b) 或者按照本网站上的说明，使用适当的参数将 OpenOffice 设置为 Windows 服务： http://www.artofsolving.com/node/10
5) From PHP run this command:
5) 从 PHP 运行这个命令：
exec('python "C:\Program Files\OpenOffice.org 3\program\DocumentConverter.py" path_to_doc\test.doc path_to_output_pdf\test.pdf"');
exec('python "C:\Program Files\OpenOffice.org 3\program\DocumentConverter.py" path_to_doc\test.doc path_to_output_pdf\test.pdf"');
Yay, what a neat and pretty solution!
是的，多么简洁漂亮的解决方案！

That sounds like open office needs to interact with the desktop and isn't allowed to since it was invoked by a service without the SERVICE_INTERACTIVE_PROCESSflag.
这听起来像是开放式办公室需要与桌面交互并且不允许，因为它是由没有SERVICE_INTERACTIVE_PROCESS标志的服务调用的。
