Qt WebEngine设置socks5代理

Question

我想为我的 Qt WebEngine 应用程序设置 socks5 代理。我用 PyQt5.8 , QT5.8.

我通过 danted v1.4.1 设置了一个 socks5 服务器。我测试了我的 socks5 服务器，它运行良好。但是当我在我的应用程序中使用它时，danted 记录错误：

error after reading 3 bytes in 0 seconds: client offered no acceptable authentication method

这是我的代码：

def set_proxy():
    from PyQt5.QtNetwork import QNetworkProxy
    proxy = QNetworkProxy()

    from six.moves.urllib import parse as urlparse
    string_proxy = "socks5://username:password@ip:port"
    urlinfo = urlparse.urlparse(string_proxy)
    proxy = QNetworkProxy()
    if urlinfo.scheme == 'socks5':
        proxy.setType(QNetworkProxy.Socks5Proxy)
    else:
        proxy.setType(QNetworkProxy.NoProxy)
    if urlinfo.hostname != None:
        proxy.setHostName(urlinfo.hostname)
    if urlinfo.port != None:
        proxy.setPort(urlinfo.port)
    if urlinfo.username != None:
        proxy.setUser(urlinfo.username)
    else:
        proxy.setUser('')
    if urlinfo.password != None:
        proxy.setPassword(urlinfo.password)
    else:
        proxy.setPassword('')
    QNetworkProxy.setApplicationProxy(proxy)

谁能帮帮我？

添加 proxyAuthenticationRequired 信号

def set_proxy(string_proxy):
    proxy = QNetworkProxy()
    urlinfo = urlparse.urlparse(string_proxy)
    if urlinfo.scheme == 'socks5':
        proxy.setType(QNetworkProxy.Socks5Proxy)
    elif urlinfo.scheme == 'http':
        proxy.setType(QNetworkProxy.HttpProxy)
    else:
        proxy.setType(QNetworkProxy.NoProxy)
    proxy.setHostName(urlinfo.hostname)
    proxy.setPort(urlinfo.port)
    proxy.setUser(urlinfo.username)
    proxy.setPassword(urlinfo.password)
    QNetworkProxy.setApplicationProxy(proxy)

def handleProxyAuthReq(url, auth, proxyhost):
    auth.setUser(username)
    auth.setPassword(password)

webView = QtWebEngineWidgets.QWebEngineView()
#proxy_string = "http://username:password@ip:port"
proxy_string = "socks5://username:password@ip:port"
set_proxy(proxy_string)
webView.page().proxyAuthenticationRequired.connect(handleProxyAuthReq)

我用我的 Http 代理 测试了它，它的措辞。但是当我使用Socks5代理时，无法发出proxyAuthenticationRequired信号。

QtWebEngine does not handle 来自 QNetworkProxy 的 username/password 信息：

All other proxy settings such as QNetworkProxy::rawHeader(), QNetworkProxy::user(), or QNetworkProxy::password() are ignored.

您需要在那里处理 proxyAuthenticationRequired 和身份验证。

看起来像 Chromium does not support 使用 SOCKS 代理进行身份验证。
