問題描述

我正在構建一個從 Python 調用的簡單 Web 應用程序.我正在使用下面的代碼.以編程方式授予對 Cam & 的訪問權限的最簡單方法是什么?加載此頁面時的麥克風?我只在網上找到了 C++ 示例，在 Python 代碼中找不到這樣做的方法.

I am building a simple web app called from Python. I am using the below code. What is the easiest way to programatically grant access to the Cam & Mic when this page is loaded? I have only found C++ examples on the web and cannot find a way to do this within Python code.

from PyQt5.QtWidgets import QApplication
from  PyQt5.QtWebEngineWidgets import QWebEngineView
from PyQt5.QtCore import QUrl

app = QApplication([])

view = QWebEngineView()
view.load(QUrl("https://test.webrtc.org/"))
view.show()
app.exec_()

推薦答案

要授予權限，您必須使用 QWebEnginePage 的 ="noreferrer">setFeaturePermission 方法，但必須當視圖發出 featurePermissionRequested 時要求您這樣做信號，這將指示 url 和 feature.p>

To give permission you must use the setFeaturePermission method of QWebEnginePage, but you must do it when the view asks you to do so when it emits the featurePermissionRequested signal, this will indicate the url and the feature.

from PyQt5.QtWidgets import QApplication
from PyQt5.QtWebEngineWidgets import QWebEngineView, QWebEnginePage
from PyQt5.QtCore import QUrl

class WebEnginePage(QWebEnginePage):
    def __init__(self, *args, **kwargs):
        QWebEnginePage.__init__(self, *args, **kwargs)
        self.featurePermissionRequested.connect(self.onFeaturePermissionRequested)

    def onFeaturePermissionRequested(self, url, feature):
        if feature in (QWebEnginePage.MediaAudioCapture, 
            QWebEnginePage.MediaVideoCapture, 
            QWebEnginePage.MediaAudioVideoCapture):
            self.setFeaturePermission(url, feature, QWebEnginePage.PermissionGrantedByUser)
        else:
            self.setFeaturePermission(url, feature, QWebEnginePage.PermissionDeniedByUser)

app = QApplication([])

view = QWebEngineView()
page = WebEnginePage()
view.setPage(page)
view.load(QUrl("https://test.webrtc.org/"))
view.show()
app.exec_()
