libreoffice python 操作word及excel文檔的方法
更新時(shí)間：2019年07月04日 15:10:46 作者：鴨子船長
這篇文章主要介紹了libreoffice python 操作word及excel文檔的方法，文中通過示例代碼介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來一起學(xué)習(xí)學(xué)習(xí)吧
1、開始、關(guān)閉libreoffice服務(wù)；
開始之前同步字體文件時(shí)間，是因?yàn)閯?chuàng)建soffice服務(wù)時(shí)，服務(wù)會(huì)檢查所需加載的文件的時(shí)間，如果其認(rèn)為時(shí)間不符，則其可能會(huì)重新加載，耗時(shí)較長，因此需事先統(tǒng)一時(shí)間。
使用時(shí)如果需要多次調(diào)用，最后每次調(diào)用均開啟后關(guān)閉，否則libreoffice會(huì)創(chuàng)建一個(gè)緩存文檔并越用越大，處理時(shí)間會(huì)增加。
class OfficeProcess(object):
def __init__(self):
self.p = 0
subprocess.Popen('find /usr/share/fonts | xargs touch -m -t 201801010000.00', shell=True)

self.p = subprocess.Popen('soffice --pidfile=sof.pid --invisible --accept="socket,host=localhost,port=2002;urp;"', shell=True)

resolver = local_context.getServiceManager().createInstanceWithContext('com.sun.star.bridge.UnoUrlResolver', local_context)

4、讀取doc文檔中的數(shù)據(jù)

7、從doc文檔數(shù)據(jù)生成pdf的二進(jìn)制數(shù)據(jù)
streamo = self.smgr.createInstanceWithContext('com.sun.star.io.Pipe', self.ctx)
self.doco.storeToURL('private:stream', (PropertyValue('FilterName', 0, 'writer_pdf_Export', 0), PropertyValue('OutputStream', 0, streamo, 0)))

self.VALUE = uno.Enum("com.sun.star.table.CellContentType", "VALUE")
10、替換excel的文本信息
def ImportFromJson(self, data):
doc = json.loads(data)
try:
self.__WriteText(doc['doc'])

if paragraph['length'] > 0:
try:
x = paragraph['x']
y = paragraph['y']
print("getcell:", x, y)
cell = sheet.getCellByPosition(x, y)
print("getcell done")
except:
return
if 'result' in paragraph:
for it in paragraph['result']:
print("cell=", cell.getString())
cell.setString(it['trans_sen'])
print("cell,", cell.getString(), ",done")
11、生成excel文檔二進(jìn)制數(shù)據(jù)
streamo = self.smgr.createInstanceWithContext('com.sun.star.io.Pipe', self.ctx)
self.document.storeToURL('private:stream', (PropertyValue('FilterName', 0, 'Calc MS Excel 2007 XML', 0), PropertyValue('OutputStream', 0, streamo, 0)))
streamo.flush()
_, datao = streamo.readBytes(None, streamo.available())
12、生成excel的pdf文檔
streamo = self.smgr.createInstanceWithContext('com.sun.star.io.Pipe', self.ctx)
self.document.storeToURL('private:stream', (PropertyValue('FilterName', 0, 'calc_pdf_Export', 0), PropertyValue('OutputStream', 0, streamo, 0)))
streamo.flush()
_, datap = streamo.readBytes(None, streamo.available())
