python - Qt WebEngine中QWebInspector的替代方法是什么？

代码段的示例在这里：

from PySide2 import QtCore, QtGui, QtWidgets, QtWebChannel
from PySide2.QtWebEngineWidgets import QWebEngineView, QWebEngineSettings

class AppWindow(QtWidgets.QMainWindow):

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.view = WebView(self)
        self.setCentralWidget(self.view)
        self.view.settings().setAttribute(QWebEngineSettings.JavascriptEnabled, True)
        self.view.settings().setAttribute(QWebEngineSettings.PluginsEnabled, True);
        self.page = self.view.page()
        self.page.setDevToolsPage(self.page)

        #self.inspector = QWebInspector(self) # Crash is here!!!
        #self.inspector.setPage(self.page)
        #self.inspector.hide()

上面的三行在以前的版本中运行良好。

PySide2中QWebInspector的替代方法是什么？

最佳答案

QWebEngine没有等效的QWebInspector类，因为开发工具是由基础Chrome浏览器提供的。需要设置环境变量以启用工具，然后您可以通过单独的基于Chrome的浏览器访问它们-有关完整的详细信息，请参阅Qt5文档中的Qt WebEngine Developer Tools。

以下是基于示例代码的简单演示：

import sys, os

DEBUG_PORT = '5588'
DEBUG_URL = 'http://127.0.0.1:%s' % DEBUG_PORT
os.environ['QTWEBENGINE_REMOTE_DEBUGGING'] = DEBUG_PORT

from PySide2 import QtCore, QtGui, QtWidgets, QtWebChannel
from PySide2.QtWebEngineWidgets import QWebEngineView, QWebEngineSettings

class AppWindow(QtWidgets.QMainWindow):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.view = QWebEngineView(self)
        self.setCentralWidget(self.view)
        self.view.settings().setAttribute(QWebEngineSettings.JavascriptEnabled, True)
        self.view.settings().setAttribute(QWebEngineSettings.PluginsEnabled, True)

        self.view.loadFinished.connect(self.handleLoaded)
        self.view.load('https://google.com/')

        self.inspector = QWebEngineView()
        self.inspector.setWindowTitle('Web Inspector')
        self.inspector.load(QtCore.QUrl(DEBUG_URL))

    def handleLoaded(self, ok):
        if ok:
            self.view.page().setDevToolsPage(self.inspector.page())
            self.inspector.show()

app = QtWidgets.QApplication(sys.argv)
win = AppWindow()
win.setGeometry(600, 100, 600, 480)
win.show()
app.exec_()
