使用python3的pdfminer库提取pdf文件的第一页

from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfpage import PDFPage
from io import StringIO

def extract_text_from_pdf(pdf_path):

    return_string = StringIO()
    codec = 'utf-8'
    laparams = LAParams()
    device = TextConverter(resource_manager, return_string, codec=codec, laparams=laparams)
    interpreter = PDFPageInterpreter(resource_manager, device)

    with open(pdf_path, 'rb') as file:
        for page in PDFPage.get_pages(file, check_extractable=True):
            interpreter.process_page(page)

    text = return_string.getvalue()
    return_string.close()
    return text

pdf_path = 'path/to/your/pdf/file.pdf'
first_page_text = extract_text_from_pdf(pdf_path)
print(first_page_text)
