使用pyqt5将html转换为pdf而不显示屏幕

import sys
from PyQt5.QtWidgets import QApplication
from PyQt5.QtWebEngineWidgets import QWebEngineView
from PyQt5.QtPrintSupport import QPrinter
from PyQt5.QtCore import QUrl

app = QApplication(sys.argv)

# 创建一个QWebEngineView对象
web_view = QWebEngineView()

# 加载HTML文件
web_view.load(QUrl.fromLocalFile('path/to/your/html/file.html'))

# 等待页面加载完成
web_view.loadFinished.connect(lambda: print_to_pdf(web_view))

# 打印为PDF
def print_to_pdf(web_view):
    printer = QPrinter()
    printer.setOutputFormat(QPrinter.PdfFormat)
    printer.setOutputFileName('path/to/your/output/file.pdf')
    web_view.print(printer)
    app.quit()

# 运行应用程序
sys.exit(app.exec_())
