在Selenium Webdriver中將DesiredCapabilities與FirefoxOptions合並

Question

我在C＃中使用Selenium webdriver與代理以及下面的一些其他屬性

FirefoxOptions options = new FirefoxOptions();
options.AddArguments("disable-infobars");

String proxyServer= "192.168.1.8:808";
Proxy proxy = new Proxy();

proxy.HttpProxy = proxyServer;
proxy.FtpProxy = proxyServer;
proxy.SslProxy = proxyServer;

DesiredCapabilities cap = new DesiredCapabilities();
cap.SetCapability(CapabilityType.Proxy, proxy);

var firefoxDriverService = FirefoxDriverService.CreateDefaultService();
firefoxDriverService.HideCommandPromptWindow = true;

Webdriver實例初始化為

IWebDriver driver = new FirefoxDriver(firefoxDriverService, options, TimeSpan.FromSeconds(600));

我唯一無法做的是將DesiredCapabilities與FirefoxOptions合並以使用代理。 所以我想做這樣的事情

options.SetCapability(cap);

有辦法嗎？

你有沒有嘗試過options.AddAdditionalCapability(CapabilityType.Proxy, proxy); ？

從來源 ：

public class FirefoxOptions : DriverOptions
...
        /// <summary>
        /// Provides a means to add additional capabilities not yet added as type safe options
        /// for the Firefox driver.
        /// </summary>
        /// <param name="optionName">The name of the capability to add.</param>
        /// <param name="optionValue">The value of the capability to add.</param>
        /// <exception cref="ArgumentException">
        /// thrown when attempting to add a capability for which there is already a type safe option, or
        /// when <paramref name="optionName"/> is <see langword="null"/> or the empty string.
        /// </exception>
        /// <remarks>Calling <see cref="AddAdditionalFirefoxOption(string, object)"/>
        /// where <paramref name="optionName"/> has already been added will overwrite the
        /// existing value with the new value in <paramref name="optionValue"/>.
        /// Calling this method adds capabilities to the Firefox-specific options object passed to
        /// geckodriver.exe (property name 'moz:firefoxOptions').</remarks>
        public void AddAdditionalFirefoxOption(string optionName, object optionValue)
        {
            this.ValidateCapabilityName(optionName);
            this.additionalFirefoxOptions[optionName] = optionValue;
        }
...

您可以將Proxy添加到FirefoxOptiions而不是DesiredCapabilities ，如下所示：

FirefoxOptions options = new FirefoxOptions();
options.AddArguments("disable-infobars");

String proxyServer= "192.168.1.8:808";
Proxy proxy = new Proxy();

proxy.HttpProxy = proxyServer;
proxy.FtpProxy = proxyServer;
proxy.SslProxy = proxyServer;

options.Profile.SetProxyPreferences(proxy); //this line is crucial

Answer 3

如果您所做的只是使用標准Proxy類型來設置實例化的Firefox實例的代理設置，則現代版本的.NET綁定會提供FirefoxOptions.Proxy屬性，該屬性將集成到您的代碼中，如下所示：

FirefoxOptions options = new FirefoxOptions();
options.AddArguments("disable-infobars");

String proxyServer= "192.168.1.8:808";
Proxy proxy = new Proxy();

proxy.HttpProxy = proxyServer;
proxy.FtpProxy = proxyServer;
proxy.SslProxy = proxyServer;

options.Proxy = proxy;

var firefoxDriverService = FirefoxDriverService.CreateDefaultService();
firefoxDriverService.HideCommandPromptWindow = true;

WebDriver driver = new FirefoxDriver(firefoxDriverService, options, TimeSpan.FromSeconds(600));

應該不需要在用戶配置文件中設置代理屬性，如在接受的答案中那樣。
