我试图在 openoffice 文档中定义“变量”，但我一定做错了什么，因为当我尝试使用字段显示变量的值时，我只得到一个空字符串。
这是我正在使用的代码（使用 Python UNO 桥）。有趣的是第二个功能。
import time
import subprocess
import logging
import os
import sys
import uno
from com.sun.star.text.SetVariableType import STRING
def get_uno_model(): # helper function to connect to OOo. Only interesting
# if you want to reproduce the issue locally,
# don't spend time on this one
try:
model = XSCRIPTCONTEXT.getDocument()
except NameError:
pass # we are not running in a macro
# get the uno component context from the PyUNO runtime
localContext = uno.getComponentContext()
# create the UnoUrlResolver
resolver = localContext.ServiceManager.createInstanceWithContext(
"com.sun.star.bridge.UnoUrlResolver", localContext )
# connect to the running office
try:
ctx = resolver.resolve("uno:socket,host=localhost,port=2002;"
"urp;StarOffice.ComponentContext")
except:
cmd = ['soffice', '--writer', '-accept=socket,host=localhost,port=2002;urp;']
popen = subprocess.Popen(cmd)
time.sleep(1)
ctx = resolver.resolve("uno:socket,host=localhost,port=2002;"
"urp;StarOffice.ComponentContext")
smgr = ctx.ServiceManager
# get the central desktop object
desktop = smgr.createInstanceWithContext("com.sun.star.frame.Desktop", ctx)
# access the current writer document
model = desktop.getCurrentComponent()
return model
def build_variable(model, name, value):
# find or create a TextFieldMaster with the correct name
master_prefix = u"com.sun.star.text.fieldmaster.SetExpression"
variable_names = set([_name.split('.')[-1]
for _name in model.TextFieldMasters.ElementNames
if _name.startswith(master_prefix)])
master_name = u'%s.%s' % (master_prefix, name)
if name not in variable_names:
master = model.createInstance(master_prefix)
master.Name = name
else:
master = model.TextFieldMasters.getByName(master_name)
# create the SetExpression field
field = model.createInstance(u'com.sun.star.text.textfield.SetExpression')
field.attachTextFieldMaster(master)
field.IsVisible = True
field.IsInput = False
field.SubType = STRING
field.Content = value
return field
model = get_uno_model() # local function to connect to OpenOffice
text = model.Text
field = build_variable(model, u'Toto', 'nice variable')
text.insertTextContent(text.getEnd(), field, False)
这段代码以某种方式工作（除非我删除了太多），但是如果我手动插入一个字段来显示 Toto 的值，我不会得到我期望的“nice variable”字符串，并且插入的字段没有值
