我正在尝试从Selenium 2升级到Selenium 3但旧的处理非常容易和快速不再起作用(并且文档似乎不存在)
这是目前的程序,我想要的是打开一个带有配置文件的Firefox驱动程序:SELENIUM
可悲的是,它无法正常工作并始终因错误:
而关闭未处理的类型' System.InvalidOperationException' >发生在WebDriver.dll
中其他信息:腐败的deflate流
这是我目前的计划:
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();
}
如果不加载配置文件,它只适用于新的FirefoxDriver(_service),但配置文件是必需的。
在Selenium 2中,我使用以下代码处理了它:
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,但由于驱动程序不支持带有服务和配置文件的构造函数,我真的不知道如何使其工作,任何帮助都将不胜感激

此异常是由.Net库中的错误引起的。生成配置文件的Zip的代码无法提供正确的Zip。
解决此问题的一种方法是重载FirefoxOptions
并使用.Net框架中的归档程序(System.IO.Compression.ZipArchive)而不是错误的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;
}
}
并按名称获取个人资料的目录:
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;
