我正在尝试使用 HTML Converter 将 PDF 文件转换为 HTML 格式。下面提供的是我正在使用的代码。

from django.conf import settings
settings.configure(PDF_MINER_IS_STRICT = True)
from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import HTMLConverter
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfpage import PDFPage
from cStringIO import StringIO
import re
import csv
def convert_pdf_to_html(path):
    rsrcmgr = PDFResourceManager()
    retstr = StringIO()
    codec = 'utf-8'
    laparams = LAParams()
    device = HTMLConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
    fp = file(path, 'rb')
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    password = ""
    maxpages = 0 #is for all
    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)
    fp.close()
    device.close()
    str = retstr.getvalue().encode('utf-8')
    retstr.close()
    return str.encode('utf-8')

但是在运行时，我收到以下错误：

Traceback (most recent call last):
  File "convertPDFToHTML.py", line 32, in <module>
    print convert_pdf_to_html(path)
  File "convertPDFToHTML.py", line 18, in convert_pdf_to_html
    device = HTMLConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
  File "C:\Python27\lib\site-packages\pdfminer\converter.py", line 247, in __init__
    PDFConverter.__init__(self, rsrcmgr, outfp, codec=codec, pageno=pageno, laparams=laparams)
  File "C:\Python27\lib\site-packages\pdfminer\converter.py", line 167, in __init__
    self.outfp.write(u"é")
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 0: ordinal not in range(128)

我不确定如何使 HTMLConverter 的“converter.py”遵循 unicode 编码。

请帮忙！

我设法通过使用 utf-8 编码来解释输出字符串来.decode('utf-8')代替.encode('utf-8')

from django.conf import settings
settings.configure(PDF_MINER_IS_STRICT = True)
from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import HTMLConverter
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfpage import PDFPage
from cStringIO import StringIO
import re
import csv
def convert_pdf_to_html(path):
    rsrcmgr = PDFResourceManager()
    retstr = StringIO()
    codec = 'utf-8'
    laparams = LAParams()
    device = HTMLConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
    fp = file(path, 'rb')
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    password = ""
    maxpages = 0 #is for all
    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)
    fp.close()
    device.close()
    str = retstr.getvalue().decode('utf-8')
    retstr.close()
    return str # no need to encode
