从Python调用LibreOffice时出错 [英] Error calling LibreOffice from Python

问题描述

调用LibreOffice将文档转换为文本...

Calling LibreOffice to convert a document to text...

这在linux命令行上可以正常工作:

This works fine from the linux command line:

soffice --headless --convert-to txt:"Text" document_to_convert.doc

但是当我尝试从Python运行相同的命令时出现错误:

But I get an error when I try to run the same command from Python:

subprocess.call(['soffice', '--headless', '--convert-to', 'txt:"Text"', 'document_to_convert.doc'])

错误:请重新验证输入参数...

Error: Please reverify input parameters...

如何获取从Python运行的命令?

How do I get the command to run from Python?

推荐答案

这是您应使用的代码:

subprocess.call(['soffice', '--headless', '--convert-to', 'txt:Text', 'document_to_convert.doc'])

这是您发布的同一行，但在txt:Text周围没有引号.

This is the same line you posted, without the quotes around txt:Text.

为什么会看到错误?简而言之:因为办公室不接受txt:"Text".它仅接受txt:Text.

Why are you seeing the error? Simply put: because soffice does not accept txt:"Text". It only accepts txt:Text.

它为什么在shell上起作用?您的shell隐式删除了参数周围的引号，因此要执行的命令实际上是:

Why is it working on the shell? Your shell implicitly removes quotes around arguments, so that the command that gets executed is actually:

soffice --headless --convert-to txt:Text document_to_convert.doc

尝试运行此命令:

soffice --headless --convert-to txt:\"Text\" document_to_convert.doc

行情不会被删除，您会看到请验证输入参数消息，该消息是通过Python获得的.

Quotes won't be removed and you'll see the Please verify input parameters message you are getting with Python.
