c# - 更改每个文件的下载位置和名称

Question

我正在使用 Selenium 和 Chrome WebDriver 进行自动化。该应用程序必须进行一系列下载，这些下载需要以不同的名称(数据 + 报告类型)和与我正在下载的报告类型匹配的文件夹保存。

问题是我在实例化新驱动时只能设置默认目录

var chromeOptions = new ChromeOptions();
chromeOptions.AddUserProfilePreference("download.default_directory", downloadDirectory);
chromeOptions.AddUserProfilePreference("intl.accept_languages", "nl");
chromeOptions.AddUserProfilePreference("disable-popup-blocking", "true");

IWebDriver driver = new ChromeDriver(@"location chromeDriver", chromeOptions);

driver.Navigate().GoToUrl(url);

因此，我无法重命名文件名或选择相应的目录。有谁知道我该怎么做？

您可以将 MS UI 自动化与 TestStack.White 结合使用。这非常困难，但确实有效。

using System.Text.RegularExpressions;
using System.Windows.Automation;
using TestStack.White.InputDevices;
using TestStack.White.UIItems;
using TestStack.White.UIItems.Finders;
using TestStack.White.UIItems.WindowItems;
...
public class SaveAsWindow
{
    AutomationElement _dialog;
    Window _win;

    public SaveAsWindow(string title)
    {
        List<Window> winList = TestStack.White.Desktop.Instance.Windows();
        foreach (Window win in winList)
        {
            Regex r = new Regex(title, RegexOptions.IgnoreCase);
            Match m = r.Match(win.Title);
            if (m.Success)
            {
                _win = win;
            }
        }
        _dialog = _win.GetElement(SearchCriteria.ByControlType(ControlType.Window));
    }

    public void Close()
    {

        Condition condition = new PropertyCondition(AutomationElement.NameProperty, "Cancel");
        AutomationElement noButton = _dialog.FindFirst(TreeScope.Children, condition);

        System.Windows.Point p = noButton.GetClickablePoint();
        Mouse.Instance.Click(p);
    }

    public string FileName
    {
        set
        {
            TextBox fileName =_win.Get<TextBox>(SearchCriteria.ByAutomationId("1001"));
            fileName.Text = value;
        }
    }

    public void Save()
    {
        Condition condition = new PropertyCondition(AutomationElement.AutomationIdProperty, "1");
        AutomationElement saveButton = _dialog.FindFirst(TreeScope.Children, condition);

        System.Windows.Point p = saveButton.GetClickablePoint();
        Mouse.Instance.Click(p);
        System.Threading.Thread.Sleep(1000);
    }
}

//// Usage
IWebDriver driver = new ChromeDriver(@"location chromeDriver", chromeOptions);
driver.Navigate().GoToUrl(url);
// it did something and save as window appears.
var saveWindow = new SaveAsWindow("title of Chrome browser");
saveWindow.FileName = "c:\what-ever.xlsx";
saveWindow.Save();
