我使用Selenium和java来自动化基于Web的应用程序.我无法与浏览按钮交互

Question

尝试单击浏览按钮时，显示Web驱动程序无效参数异常。该文件只能通过发送密钥附加，请帮助

显示运行时异常 这是我的 XPath

@FindBy(how=How.XPATH,using="//input[@type='file']")
private WebElement eleAttachDoc;

Answer 1

您正在尝试单击并上传文件。 单击时应显示一个窗口弹出窗口，硒无法处理，因此 可以使用带有文件位置(绝对路径(参数的 SendKeys 来处理此元素，该参数将直接上传文件。

Answer 2

根据问题，您正在尝试上传文件。

在某些字段中，根据设计，您可以直接发送路径。

driver.findElement(By.id("uploadfile_cv")).sendKeys("C:\mycv.pdf");

如果上述解决方案不仅有效，则可以使用 Java 工具包上传文件。请参阅下面的代码。请尝试此操作并提供反馈。
