libreoffice python 操作word及excel文档的方法


Posted in Python onJuly 04, 2019

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

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

        l += self.__ParseParagraph(element, func)
      elif element.supportsService('com.sun.star.text.TextTable'):

      if portion.TextPortionType == 'Text':
        l += self.__ParsePortionText(portion, self.__Callback(p['paragraph']))
      elif portion.TextPortionType == 'SoftPageBreak':
        pass
      elif portion.TextPortionType == 'TextField':
        l += self.__ParsePortionText(portion, self.__Callback(p['paragraph']))
      else:
        l += self.__ParseTextContent(portion, self.__Callback(p['paragraph']))
    if hasattr(paragraph, 'createContentEnumeration'):
      l += self.__ParseTextContent(paragraph, self.__Callback(p['paragraph']))
    p['length'] = l
    func(p)
    return l

  def __ParseTextContent(self, textcontent, func):
    l = 0
    content_it = textcontent.createContentEnumeration('com.sun.star.text.TextContent')
    while content_it.hasMoreElements():

    pv2 = PropertyValue()
    pv2.Name = 'MimeType'
    pv2.Value = 'image/png'
    gp.storeGraphic(portion_graphic.Graphic, (pv1, pv2))
    stream.getOutputStream().flush()
    stream.seek(0)
    l = stream.getInputStream().available()
    b = uno.ByteSequence(b'')
    stream.seek(0)
    l, b = stream.getInputStream().readBytes(b, l)

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:

        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):

    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

    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'])

        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 = None
            continue
        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())
