在MVC C#环境中将文档转换为pdf [英] Converting a doc to a pdf in a mvc c# environment
问题描述
我有一个在特定用户(app.pool用户)下运行的c#MVC应用程序. 我需要将doc或docx文件转换为pdf.
Hi I've got a c# MVC application running under a particular user (app.pool user). I need to convert a doc or docx file to a pdf.
我认为一个不错的选择是使用libreoffice触发将启动此过程的进程.
I thought a good option would be to use libreoffice to fire a process that would start this.
为了使自己的生活更轻松(如果libreoffice无法正常工作)，我使用了一个批处理文件.
To make life easier for myself (and if libreoffice shouldn't work) I used a batch file.
echo on
SET var1=%2
IF "%var1:~-1%"=="\" SET var1=%var1:~0,-1%
cd %var1%
echo %1
echo %var1%
start /wait "" "C:\Program Files (x86)\LibreOffice 4\program\soffice" -headless -convert-to pdf %1 -outdir %var1%
我的启动代码如下.
var ba = @"C:\inetpub\wwwroot\apps\xxxxxxxxx\Services\convert.bat";
fullPath = @"C:\inetpub\wwwroot\apps\xxxxxxxxx\Files\Temp\636295920370843147.doc";
var tempPath = @"C:\inetpub\wwwroot\apps\xxxxxxxxx\Files\Temp";
string command = ba;
//Process.Start(command, fullPath + " " + tempPath);
var processInfo = new ProcessStartInfo("cmd.exe", "/c " + command + " "+ fullPath+ " "+ tempPath);
processInfo.CreateNoWindow = false;
processInfo.UseShellExecute = false;
processInfo.RedirectStandardError = true;
processInfo.RedirectStandardOutput = true;
var process = Process.Start(processInfo);
process.OutputDataReceived += (object sender, DataReceivedEventArgs e) =>
Trace.WriteLine("output>>" + e.Data);
process.BeginOutputReadLine();
process.ErrorDataReceived += (object sender, DataReceivedEventArgs e) =>
Trace.WriteLine("error>>" + e.Data);
process.BeginErrorReadLine();
process.WaitForExit();
Trace.WriteLine("ExitCode: {0}", process.ExitCode.ToString());
process.Close();
这似乎确实可以手动运行，但是当我运行代码时，我可以看到整个过程停滞在转换过程中.查看线程，似乎加载了gdiplus.dll，我认为这是一个图形模块，看起来似乎不正确.
This does seem to work manually but when I run the code I can see the whole thing just stalls around the conversion. Looking at the threads and it seems to load the gdiplus.dll which I think is a graphics module which doesn't seem right.
但是，当我将其复制并粘贴到Windows中的运行"框中时，该过程运行正常，并且生成了pdf.
The process though when I copy and paste that into my 'run' box in windows works fine and the pdf is made.
我检查了app.pool用户是否可以访问libreoffice以及包含文件的文件夹.
我以app.pool用户的身份运行它，在C#中它停在process.WaitForExit();上
线.直到我终止该过程.
I've checked that the app.pool user has access to both libreoffice and also the folder with the files.
I've ran this as the app.pool user, in the c# it just stalls on the process.WaitForExit();
line. Until I kill the process.
有什么想法吗?
我还尝试了许多不同的方式来执行办公室转换.刚好从C#开始-libreoffice 4,5.
I've also tried many different ways of executing the soffice conversion. just straight from the c# - libreoffice 4,5.
我已经看到有些人将libreoffice用作服务，这是一个选择吗?如果可以，怎么办? 理查德
I've seen some people use libreoffice as a service, is this an option? If so how? Richard
编辑 嗯，只是将应用程序池用户更改为我自己，现在可以使用，因此标准应用程序池用户具有权限.如何找出什么......
EDIT Ah, just changed the app Pool user to myself and now it works, so there is a permissions thing with the standard app pool user. How to find out what....
推荐答案
我将用户添加到计算机上的Administrators组中，并重新启动了计算机，然后计算机正常工作.
I added the user into the administrators group on the computer and restarted the machine, then it worked.
这可能不是最好的解决方案，但是经过2天的尝试，我不再争论了.
It might not be the best solution but after 2 days of trying to get this to work I'm not going to argue.
