C＃Selenium Webdriver-如何使用代理验证？

Question

当我使用身份验证运行时，该程序会出现错误。

        var options = new FirefoxOptions();

        string proxyInfo = "user:password@host:port";
        var proxy = new Proxy
        {
            HttpProxy = proxyInfo,
            SslProxy = proxyInfo,
            FtpProxy = proxyInfo,
        };
        options.Proxy = proxy;

        var service = FirefoxDriverService.CreateDefaultService();
        service.FirefoxBinaryPath = "C:\\Program Files\\Mozilla Firefox\\firefox.exe";

        WebDriver = new FirefoxDriver(service, options);

当我在没有身份验证的情况下运行它时，该程序可以工作。它仅在打开网站时要求进行身份验证。

        var options = new FirefoxOptions();

        string proxyInfo = "host:port";
        var proxy = new Proxy
        {
            HttpProxy = proxyInfo,
            SslProxy = proxyInfo,
            FtpProxy = proxyInfo,
        };
        options.Proxy = proxy;

        var service = FirefoxDriverService.CreateDefaultService();
        service.FirefoxBinaryPath = "C:\\Program Files\\Mozilla Firefox\\firefox.exe";

        WebDriver = new FirefoxDriver(service, options);
