libreoffice python 操作word及excel文档的方法
1、开始、关闭libreoffice服务；
开始之前同步字体文件时间，是因为创建soffice服务时，服务会检查所需加载的文件的时间，如果其认为时间不符，则其可能会重新加载，耗时较长，因此需事先统一时间。
使用时如果需要多次调用，最后每次调用均开启后关闭，否则libreoffice会创建一个缓存文档并越用越大，处理时间会增加。
class OfficeProcess(object):
def __init__(self):
self.p = 0
subprocess.Popen('find /usr/share/fonts | xargs touch -m -t 201801010000.00', shell=True)
def start_office(self):
self.p = subprocess.Popen('soffice --pidfile=sof.pid --invisible --accept="socket,host=localhost,port=2002;urp;"', shell=True)
while True:
try:
local_context = uno.getComponentContext()
resolver = local_context.getServiceManager().createInstanceWithContext('com.sun.star.bridge.UnoUrlResolver', local_context)
resolver.resolve('uno:socket,host=localhost,port=2002;urp;StarOffice.ComponentContext')
return
except:
print(ts(), "wait for connecting soffice...")
time.sleep(1)
continue
def stop_office(self):
with open("sof.pid", "rb") as f:
try:
os.kill(int(f.read()), signal.SIGTERM)
self.p.wait()
except:
pass
2、init service manager
local_context = uno.getComponentContext()
service_manager = local_context.getServiceManager()
resolver = service_manager.createInstanceWithContext('com.sun.star.bridge.UnoUrlResolver', local_context)
self.ctx = resolver.resolve('uno:socket,host=localhost,port=2002;urp;StarOffice.ComponentContext')

3、从二进制数据中读取doc文档

istream = self.smgr.createInstanceWithContext('com.sun.star.io.SequenceInputStream', self.ctx)
istream.initialize((uno.ByteSequence(data), ))

y = paragraph['y']
print("getcell:", x, y)
cell = sheet.getCellByPosition(x, y)

print("cell,", cell.getString(), ",done")
11、生成excel文档二进制数据
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文档
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)))
