PDF 抓取不会使用 PyPDF2 加载文本

如何解决PDF 抓取不会使用 PyPDF2 加载文本

我正在尝试从 PDF 列表中提取所有文本，但在从对象中提取文本时遇到错误。知道是什么原因造成的吗？

ls = os.listdir(resumes)
pdf = [s for s in ls if '.pdf' in s]
print(pdf)

for p in pdf:
    pdfFileObj = open(os.path.join(resumes,p),'rb') 
    pdfReader = PyPDF2.PdfFileReader(pdfFileObj)
    print(pdfReader.numPages)
    pageObj = pdfReader.getPage(0) 
    print(pageObj.extractText()) 
    pdfFileObj.close() 

错误：

  File "C:\Program Files\Python39\lib\encodings\cp1252.py",line 19,in encode
    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
UnicodeEncodeError: 'charmap' codec can't encode character '\u0141' in position 305: character maps to <undefined>

解决方法

用 pdfplumber 试试这个：

import pdfplumber
import os 

resumes = "C:\\path\\to\\resumes\\"
ls = os.listdir(resumes)
pdf_files = [s for s in ls if '.pdf' in s]
alltext = ""

for pdf_file in pdf_files:
    pdf_path = resumes + pdf_file
    pdf = pdfplumber.open(pdf_path)
    nb_pages = len(pdf.pages)
    print(nb_pages)

    for n in range(0,nb_pages): # if you want to extract text from all the document
        p = pdf.pages[n]
        text = p.extract_text()

        if text is None:
            continue 

        alltext += text

    print(alltext) # This is will print all the text
    alltext = "" # reinitialize this variable
