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。

classOfficeProcess(object):def __init__(self):self.p=0subprocess.Popen('find /usr/share/fonts | xargs touch -m -t 201801010000.00', shell=True)defstart_office(self):self.p= subprocess.Popen('soffice --pidfile=sof.pid --invisible --accept="socket,host=localhost,port=2002;urp;"', shell=True)whileTrue: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')returnexcept:print(ts(), "wait for connecting soffice...")time.sleep(1)continuedefstop_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')self.smgr=self.ctx.ServiceManagerself.desktop= self.smgr.createInstanceWithContext('com.sun.star.frame.Desktop', self.ctx)

3、从二进制数据中读取doc文档

defImportFromMemory(self, data):istream= self.smgr.createInstanceWithContext('com.sun.star.io.SequenceInputStream', self.ctx)istream.initialize((uno.ByteSequence(data), ))pv=PropertyValue()pv.Name= 'InputStream'pv.Value=istreamself.doc= {'doc': []}try:self.document= self.desktop.loadComponentFromURL('private:stream/swriter', '_blank', 0, (pv, ))self.text=self.document.getText()except:self.text= None

4、读取doc文档中的数据
