使用python pdfminer提取整个pdf数据

Question

我正在使用pdfminer使用python从pdf文件中提取数据。我想提取pdf中存在的所有数据，而不管它是图像还是文本，无论它是什么。我们可以在一行中执行此操作吗（如果需要，可以执行两条操作，而无需进行大量工作）。任何帮助表示赞赏。提前致谢

Answer 1

对于Python 3：点安装pdfminer.sixfrom pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreterfrom pdfminer.converter import TextConverterfrom pdfminer.layout import LAParamsfrom pdfminer.pdfpage import PDFPagefrom io import StringIOdef convert_pdf_to_txt(path, codec='utf-8'):    rsrcmgr = PDFResourceManager()    retstr = StringIO()    laparams = LAParams()    device = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)    fp = open(path, 'rb')    interpreter = PDFPageInterpreter(rsrcmgr, device)    password = ""    maxpages = 0    caching = True    pagenos=set()    for page in PDFPage.get_pages(fp, pagenos, maxpages=maxpages, password=password,caching=caching, check_extractable=True):        interpreter.process_page(page)    text = retstr.getvalue()    fp.close()    device.close()    retstr.close()    return text

对于python3，还有另一个：pip install pdfminer3kfrom pdfminer.pdfinterp import PDFResourceManager, process_pdffrom pdfminer.converter import TextConverterfrom pdfminer.layout import LAParamsfrom io import StringIOimport timefrom functools import wrapsdef fn_timer(function)://this is for calculating the run time(function)    @wraps(function)    def function_timer(*args, **kwargs):        t0 = time.time()        result = function(*args, **kwargs)        t1 = time.time()        print ("Total time running %s: %s seconds" %                ('test', str(t1-t0))                )        return result    return function_timer@fn_timerdef convert_pdf(path, pages):    rsrcmgr = PDFResourceManager()    retstr = StringIO()    laparams = LAParams()    device = TextConverter(rsrcmgr, retstr, laparams=laparams)    fp = open(path, 'rb')    process_pdf(rsrcmgr, device, fp,pages)    fp.close()    device.close()    str = retstr.getvalue()    retstr.close()    return strfile = r'M:\a.pdf'print(convert_pdf(file,[1,]))
