C# Appium/Selenium Derive WindowsElement 抛出错误
如何解决C# Appium/Selenium Derive WindowsElement 抛出错误？
在我的 C# .NET Framework 4.8 项目中，我试图派生 WindowsElement 类以在新类中实现一些附加功能。 例如 ClickInMiddleOfControl、IsVisible 或 SelectedItem（在组合框中）。
public class WindowsElementWrapper : WindowsElement
{
public WindowsElementWrapper(RemoteWebDriver parent,string id) : base(parent,id) { }
public void ClickInMiddleOfControl()
{
var rect = this.Rect;
var offsetx = (int)(0.5 * rect.Width);
var offsety = (int)(0.5 * rect.Height);
new Actions(Helper.Session)
.MovetoElement(this,0)
.MoveByOffset(offsetx,offsety)
.Click()
.Build()
.Perform();
}
}
然后我尝试将 WindowsElement 转换为我的 WindowsElementWrapper。
var element = (WindowsElementWrapper)Session.FindElementByName("ElementName");
element.ClickInMiddleOfControl();
但在运行时我收到以下错误消息：
system.invalidCastException: ''无法转换类型的对象 OpenQA.Selenium.Appium.Windows.WindowsElement'' 输入 ''WEW.WindowsElementWrapper''。''
是否不能从 WindowsElement 类派生？还是我犯了一个根本性的错误？
解决方法
从 WindowsElement 到 WindowsElementWrapper 的转换是沮丧。
为了使向下转型成功，对象的运行时类型必须是目标类型本身，或者是从它派生的类型。
虽然 WindowsElementWrapper 是 WindowsElement，但 WindowsElement 不一定是 WindowsElementWrapper。
换句话说，这种向下转换永远不会成功，除非 SeleniumAPI 实例化对象作为一个 WindowsElementWrapper 开始。
为了实现您想要做的事情，您可以应用以下设计之一：
组成
public class WindowsElementWrapper
{
private readonly WindowsElement element;
public WindowsElementWrapper(WindowsElement element,(int Width,int Height) rect)
{
this.element = element;
Rect = rect;
}
public (int Width,int Height) Rect { get; init; }
public void ClickInMiddleOfControl()
=> new Actions(Helper.Session)
.MoveToElement(element,0)
.MoveByOffset(Rect.Width / 2,Rect.Height / 2)
.Click()
.Build()
.Perform();
}
扩展方法
public static class Extensions
{
public static void ClickInMiddleOfControl(this WindowsElement source,int Height) rect)
=> new Actions(Helper.Session)
.MoveToElement(source,0)
.MoveByOffset(rect.Width / 2,rect.Height / 2)
.Click()
.Build()
.Perform();
}
最好的问候
c# – 是否可以在不安装Selenium Server的情况下使用ISelenium / DefaultSelenium？
我之前使用IWebDriver控制IE进行测试.但是IWebDriver和IWebElement支持的方法非常有限.我发现属于Selenium命名空间的ISelenium / DefaultSelenium非常有用.如何在不安装Selenium Server的情况下使用它们来控制IE？
这是DefaultSelenium的构造函数：
ISelenium sele = new DefaultSelenium(**serveraddr**,**serverport**,browser,url2test); sele.Start(); sele.open(); ...
似乎我必须在创建ISelenium对象之前安装Selenium Server.
我的情况是,我正在尝试使用C#Selenium构建一个.exe应用程序,它可以在不同的PC上运行,并且不可能在所有PC上安装Selenium Server(你永远不知道哪个是下一个运行应用程序).
有没有人知道如何在不安装服务器的情况下使用ISelenium / DefaultSelenium？
谢谢！
解决方法
在不使用RC Server的情况下,Java中有一些解决方案：
1)对于selenium浏览器启动：
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setbrowserName("safari");
CommandExecutor executor = new SeleneseCommandExecutor(new URL("http://localhost:4444/"),new URL("http://www.google.com/"),capabilities);
WebDriver driver = new RemoteWebDriver(executor,capabilities);
2)对于selenium命令：
// You may use any WebDriver implementation. Firefox is used here as an example
WebDriver driver = new FirefoxDriver();
// A "base url",used by selenium to resolve relative URLs
String baseUrl = "http://www.google.com";
// Create the Selenium implementation
Selenium selenium = new WebDriverBackedSelenium(driver,baseUrl);
// Perform actions with selenium
selenium.open("http://www.google.com");
selenium.type("name=q","cheese");
selenium.click("name=btnG");
// Get the underlying WebDriver implementation back. This will refer to the
// same WebDriver instance as the "driver" variable above.
WebDriver driverInstance = ((WebDriverBackedSelenium) selenium).getWrappedDriver();
//Finally,close the browser. Call stop on the WebDriverBackedSelenium instance
//instead of calling driver.quit(). Otherwise,the JVM will continue running after
//the browser has been closed.
selenium.stop();

谷歌在C#中有类似的东西.没有其他方法可以实现这一目标.
http.post请求未收到任何数据
根据文档，Net::HTTP post方法返回一个HTTPResponse对象。由于仅返回一个对象，因此只会为resp提供一个值。
您提到“响应包含预期的数据”。我想知道您是否只需要使用body方法。 resp.body是否会为您提供所需的数据？
