使用Selenium 3启动特定的Firefox配置文件 [英] Starting a specific Firefox Profile with Selenium 3

问题描述

我正在尝试从Selenium 2升级到Selenium 3，但是旧的处理方式（非常简单，快速）不再起作用了（而且文档似乎不存在）

I am trying to upgrade from Selenium 2 to Selenium 3 but the old handling, which was pretty easy and fast doesn't work anymore (and the documentation is nonexisting as it seems)

此刻是程序，我想要打开一个配置文件为：SELENIUM的Firefox驱动程序

This is the program at the moment and what I want is to open a Firefox driver with the profile: SELENIUM

不幸的是，它始终无法正常工作因错误而关闭：

Sadly it doesn't work and always shuts down with the Error:

WebDriver.dll中发生了'System.InvalidOperationException'类型的未处理异常

An unhandled exception of type 'System.InvalidOperationException' > occurred in WebDriver.dll

其他信息：腐败的放气流

Additional information: corrupt deflate stream

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），但该配置文件

Without Loading the Profile it works with just new FirefoxDriver(_service) but the profile is mandatory.

在Selenium 2中，我使用以下代码对其进行了处理：

In Selenium 2 I handled it with this code:

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);

快速而简单，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，我不这样做真的不知道如何使它正常工作，将不胜感激

Fast and simple, but as the Driver doesn't support a Constructor with service and profile I don't really know how to get this to work, any help would be appreciated

推荐答案

此异常是由于中的错误所致。网络图书馆。

This exception is due to a bug in the .Net library. The code generating the Zip of the profile is failing to provide a proper Zip.

一种解决此问题的方法是重载 FirefoxOptions

One way to overcome this issue would be to overload FirefoxOptions and use the archiver from .Net framework (System.IO.Compression.ZipArchive) instead of the faulty 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;
    }

}

并按名称获取配置文件的目录：

And to get the directory for a profile by name:

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;
