    path_wkthmltopdf = r'D:\\Program Files\\wkhtmltopdf\\bin\\wkhtmltopdf.exe'
    config = pdfkit.configuration(wkhtmltopdf=path_wkthmltopdf)
    # Generate a PDF file, TO_FILE is the file path
    pdfkit.from_url(url, to_file, configuration=config)
    print('Finish')

#               URL, convert to PDF
url_to_pdf(r'https://zhuanlan.zhihu.com/p/69869004', 'out_1.pdf')

2. HTML file generation PDF [pdfkit.from_file () function]

#      
import pdfkit

'' 'Generates the HTML file' '' '
def html_to_pdf(html, to_file):
    # Incorporate the WKHTMLTOPDF.EXE program absolute path to config object
    path_wkthmltopdf = r'D:\\Program Files\\wkhtmltopdf\\bin\\wkhtmltopdf.exe'
    config = pdfkit.configuration(wkhtmltopdf=path_wkthmltopdf)
    # Generate a PDF file, TO_FILE is the file path
    pdfkit.from_file(html, to_file, configuration=config)
