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')    self.smgr = self.ctx.ServiceManager    self.desktop = self.smgr.createInstanceWithContext('com.sun.star.frame.Desktop', self.ctx)

3、从二进制数据中读取doc文档

def ImportFromMemory(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 = istream    self.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

5、写doc文档

self.doco = self.desktop.loadComponentFromURL('private:factory/swriter', '_blank', 0, ())    self.texto = self.doco.getText()    self.cursoro = self.texto.createTextCursor()    self.cursoro.ParaBottomMargin = 500

def __WriteText(self, text, texto, cursoro):    for it in text:      if 'paragraph' in it:        self.__WriteParagraph(it, texto, cursoro)      elif 'image' in it:        self.__WritePortionGraphic(it, texto, cursoro)      elif 'table' in it:        self.__WriteTable(it, texto, cursoro)  def __WriteParagraph(self, paragraph, texto, cursoro):    if paragraph['length'] > 0:      if 'result' in paragraph:        for it in paragraph['result']:          texto.insertString(cursoro, it['trans_sen'], False)      else:        texto.insertString(cursoro, paragraph['paragraph'], False)      texto.insertControlCharacter(cursoro, ControlCharacter.PARAGRAPH_BREAK, False)  def __WritePortionGraphic(self, portion_graphic, texto, cursoro):    png_base64 = portion_graphic['image']    png = base64.b64decode(png_base64)    gp = self.smgr.createInstanceWithContext('com.sun.star.graphic.GraphicProvider', self.ctx)    istream = self.smgr.createInstanceWithContext('com.sun.star.io.SequenceInputStream', self.ctx)    istream.initialize((uno.ByteSequence(png), ))    pv = PropertyValue()    pv.Name = 'InputStream'    pv.Value = istream    actualsize = uno.createUnoStruct('com.sun.star.awt.Size')    actualsize.Height = portion_graphic['actualheight'] if 'actualheight' in portion_graphic else portion_graphic['height']    actualsize.Width = portion_graphic['actualwidth'] if 'actualwidth' in portion_graphic else portion_graphic['width']    graphiccrop = uno.createUnoStruct('com.sun.star.text.GraphicCrop')    graphiccrop.Top = portion_graphic['croptop'] if 'croptop' in portion_graphic else 0    graphiccrop.Bottom = portion_graphic['cropbottom'] if 'cropbottom' in portion_graphic else 0    graphiccrop.Left = portion_graphic['cropleft'] if 'cropleft' in portion_graphic else 0    graphiccrop.Right = portion_graphic['cropright'] if 'cropright' in portion_graphic else 0    image = self.doco.createInstance('com.sun.star.text.TextGraphicObject')    image.Surround = NONE    image.Graphic = gp.queryGraphic((pv, ))    image.Height = portion_graphic['height']    image.Width = portion_graphic['width']    image.setPropertyValue('ActualSize', actualsize)    image.setPropertyValue('GraphicCrop', graphiccrop)    texto.insertTextContent(cursoro, image, False)    texto.insertControlCharacter(cursoro, ControlCharacter.PARAGRAPH_BREAK, False)  def __WriteTable(self, table, texto, cursoro):    tableo = self.doco.createInstance('com.sun.star.text.TextTable')    tableo.initialize(table['row'], table['column'])    texto.insertTextContent(cursoro, tableo, False)#    texto.insertControlCharacter(cursoro, ControlCharacter.PARAGRAPH_BREAK, False)    tcursoro = tableo.createCursorByCellName("A1")    hitbug = False    if table['row'] > 1:      tcursoro.goDown(1, True)      hitbug = tcursoro.getRangeName() == 'A1'    for ri in sorted([int(r) for r in table['table'].keys()]):      rs = table['table'][str(ri)]      for ci in sorted([int(c) for c in rs.keys()]):        cell = rs[str(ci)]        if hitbug == False and (cell['rowspan'] > 1 or cell['colspan'] > 1):          tcursoro.gotoCellByName(cell['name'], False)          if cell['rowspan'] > 1:tcursoro.goDown(cell['rowspan'] - 1, True)          if cell['colspan'] > 1:tcursoro.goRight(cell['colspan'] - 1, True)          tcursoro.mergeRange()        ctexto = tableo.getCellByName(cell['name'])        if ctexto == None:          continue        ccursoro = ctexto.createTextCursor()        ccursoro.CharWeight = FontWeight.NORMAL        ccursoro.CharWeightAsian = FontWeight.NORMAL        ccursoro.ParaAdjust = LEFT        self.__WriteText(cell['content'], ctexto, ccursoro)

6、生成二进制的doc文档数据

    streamo = self.smgr.createInstanceWithContext('com.sun.star.io.Pipe', self.ctx)    self.doco.storeToURL('private:stream', (PropertyValue('FilterName', 0, 'MS Word 2007 XML', 0), PropertyValue('OutputStream', 0, streamo, 0)))    streamo.flush()    _, datao = streamo.readBytes(None, streamo.available())

7、从doc文档数据生成pdf的二进制数据

    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)))    streamo.flush()    _, datap = streamo.readBytes(None, streamo.available())

8、读取excel二进制数据

　　def ImportFromMemory(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 = istream    self.doc = {'doc': []}    try:      print("before loadComponentFromURL")      self.document = self.desktop.loadComponentFromURL('private:stream/scalc', '_blank', 0, (pv, ))      self.sheets = self.document.getSheets()      print("ImportFromMemory done")    except:      print("ImportFromMemory failed")      self.sheets = None

9、读取excel的文本数据

  def ExportToJson(self):    try:      l = self.__ParseText(self.sheets, self.__Callback(self.doc['doc']))      self.doc['length'] = l    except:      self.doc = {'doc': [], 'length': 0}    return json.dumps(self.doc)

  def __ParseText(self, sheets, func):    l = 0    sheets_it = sheets.createEnumeration()    while sheets_it.hasMoreElements():      element = sheets_it.nextElement()      if element.supportsService('com.sun.star.sheet.Spreadsheet'):        l += self.__ParseSpreadsheet(element, func)    return l  def __ParseSpreadsheet(self, spreadsheet, func):    l = 0    p = {'spreadsheet': []}    visible_cells_it = spreadsheet.queryVisibleCells().getCells().createEnumeration()    while visible_cells_it.hasMoreElements():      cell = visible_cells_it.nextElement()      type = cell.getType()      if type == self.EMPTY:        print("cell.type==empty")      elif type == self.VALUE:        print("cell.type==VALUE", "value=", cell.getValue(), cell.getCellAddress ())      elif type == self.TEXT:        print("cell.type==TEXT","content=", cell.getString().encode("UTF-8"), cell.getCellAddress ())        l += self.__ParseCellText(spreadsheet, cell, self.__Callback(p['spreadsheet']))        print("__ParseCellText=", p)      elif type == self.FORMULA:        print("cell.type==FORMULA", "formula=", cell.getValue())    p['length'] = l    func(p)    return l  def __ParseCellText(self, sheet, cell, func):    try:      x = cell.getCellAddress().Column      y = cell.getCellAddress().Row      sheetname = sheet.getName()    except:      x = -1      y = -1      sheetname = None    func({'celltext': cell.getString(), 'x': x, 'y': y, 'sheetname': sheetname, 'length': len(cell.getString())})    return len(cell.getString())

　　　　　self.EMPTY = uno.Enum("com.sun.star.table.CellContentType", "EMPTY")    self.TEXT = uno.Enum("com.sun.star.table.CellContentType", "TEXT")    self.FORMULA = uno.Enum("com.sun.star.table.CellContentType", "FORMULA")    self.VALUE = uno.Enum("com.sun.star.table.CellContentType", "VALUE")

10、替换excel的文本信息

  def ImportFromJson(self, data):    doc = json.loads(data)    try:      self.__WriteText(doc['doc'])    except:      pass

def __WriteText(self, text):    print("__WriteText begin:", text)    sheet = None    for it in text:      if 'paragraph' in it and 'sheetname' in it:        if sheet == None or sheet.getName() != it['sheetname']:          try:sheet = self.sheets.getByName(it['sheetname'])print("getsheet:", it['sheetname'], "=", sheet.getName())          except:sheet = Nonecontinue        self.__WriteParagraph(it, sheet)  def __WriteParagraph(self, paragraph, sheet):    print("__WriteParagraph")    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)))    streamo.flush()    _, datap = streamo.readBytes(None, streamo.available())
