使用Selenium 3启动特定的Firefox配置文件

selenium

我正在尝试从Selenium 2升级到Selenium 3,但是旧的处理方式(既简单又快速)不再起作用了(而且似乎不存在该文档)

这是当前的程序,我要打开带有以下配置文件的Firefox驱动程序:SELENIUM

遗憾的是,它无法正常工作,并始终因错误而关闭:

WebDriver.dll中发生类型为’System.InvalidOperationException’>的未处理异常

附加信息:损坏的放气流

这是我目前的程序:

public Program()
{
    FirefoxOptions _options = new FirefoxOptions();
    FirefoxProfileManager _profileIni = new FirefoxProfileManager();
    FirefoxDriverService _service = FirefoxDriverService.CreateDefaultService(@"C:\Programme\IMaT\Output\Release\Bin");
    _service.FirefoxBinaryPath = @"C:\Program Files (x86)\Mozilla Firefox\firefox.exe";
    try
    {
        if ((_options.Profile = _profileIni.GetProfile("SELENIUM")) == null)
        {
            Console.WriteLine("SELENIUM PROFILE NOT FOUND");
            _profile.SetPreference("network.proxy.type", 0); // disable proxy
            _profile = new FirefoxProfile();
        }
    }
    catch
    {
        throw new Exception("Firefox needs a Profile with \"SELENIUM\"");
    }
    IWebDriver driver = new FirefoxDriver(_service,_options,new System.TimeSpan(0,0,30));        
    driver.Navigate().GoToUrl("ld-hybrid.fronius.com");
    Console.Write("rtest");
}

static void Main(string[] args)
{
    new Program();
}

在不加载配置文件的情况下,它仅适用于新的FirefoxDriver(_service),但配置文件是必需的。

在Selenium 2中,我使用以下代码进行了处理:

FirefoxProfileManager _profileIni = new FirefoxProfileManager();
// use custom temporary profile
try { 
    if ((_profile = _profileIni.GetProfile("SELENIUM")) == null)
    {
        Console.WriteLine("SELENIUM PROFILE NOT FOUND");
        _profile.SetPreference("network.proxy.type", 0); // disable proxy
        _profile = new FirefoxProfile();
    }
}
catch
{
    throw new Exception("Firefox needs a Profile with \"SELENIUM\"");
}

_profile.SetPreference("intl.accept_languages", _languageConfig);
_driver = new FirefoxDriver(_profile);

快速简单,但是由于驱动程序不支持带有服务和配置文件的构造方法,我真的不知道如何使它正常工作,因此不胜感激

此异常是由于.Net库中的错误所致。生成配置文件的Zip的代码无法提供适当的Zip。

解决此问题的一种方法是重载FirefoxOptions并使用.Net框架(System.IO.Compression.ZipArchive)中的存档器,而不是出现故障ZipStorer

var options = new FirefoxOptionsEx();
options.Profile = @"C:\Users\...\AppData\Roaming\Mozilla\Firefox\Profiles\ez3krw80.Selenium";
options.SetPreference("network.proxy.type", 0);

var service = FirefoxDriverService.CreateDefaultService(@"C:\downloads", "geckodriver.exe");

var driver = new FirefoxDriver(service, options, TimeSpan.FromMinutes(1));



class FirefoxOptionsEx : FirefoxOptions {

    public new string Profile { get; set; }

    public override ICapabilities ToCapabilities() {

        var capabilities = (DesiredCapabilities)base.ToCapabilities();
        var options = (IDictionary)capabilities.GetCapability("moz:firefoxOptions");
        var mstream = new MemoryStream();

        using (var archive = new ZipArchive(mstream, ZipArchiveMode.Create, true)) {
            foreach (string file in Directory.EnumerateFiles(Profile, "*", SearchOption.AllDirectories)) {
                string name = file.Substring(Profile.Length + 1).Replace('\\', '/');
                if (name != "parent.lock") {
                    using (Stream src = File.OpenRead(file), dest = archive.CreateEntry(name).Open())
                        src.CopyTo(dest);
                }
            }
        }

        options["profile"] = Convert.ToBase64String(mstream.GetBuffer(), 0, (int)mstream.Length);

        return capabilities;
    }

}

并通过名称获取配置文件的目录:

var manager = new FirefoxProfileManager();
var profiles = (Dictionary<string, string>)manager.GetType()
    .GetField("profiles", BindingFlags.Instance | BindingFlags.NonPublic)
    .GetValue(manager);

string directory;
if (profiles.TryGetValue("Selenium", out directory))
    options.Profile = directory;
