看到这篇文章时： 我得到了大部分解决方案，但最后的 VK_ENTER 没有带我返回网页，这导致了另一个问题：返回页面视图，而不是放置图像的裁剪工具。
有人可以让我知道我需要做什么才能让它发挥作用吗？谢谢！！
这是代码：
public static void setClipboardData(String string) {
StringSelection stringSelection = new StringSelection(string);
Toolkit.getDefaultToolkit().getSystemClipboard().setContents(stringSelection, null);
}
And that is what i do, just after opening the "open" window:
setClipboardData("C:\\path to file\\example.jpg");
//native key strokes for CTRL, V and ENTER keys
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);

问题之一是 VK_ENTER 永远不会离开文件资源管理器并返回网页。如果我在测试运行时手动执行此操作，则永远找不到“保存”按钮。这是错误：

我尝试过 Actions 对象以及 JavascriptExecutor，但似乎都不起作用。
完整代码如下：
package groupPhotoUploadTest;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.*;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.openqa.selenium.interactions.Actions;
import java.awt.Robot;
import java.awt.event.KeyEvent;
import java.awt.Toolkit;
import java.awt.datatransfer.StringSelection;
public class groupPhotoUploadTest {
private static WebDriver driver;
private static String baseUrl;
public static void main(String[] args) throws Exception {
driver = new FirefoxDriver();
baseUrl = "http://loadtest1.staging.brio.viddler.com/";
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
driver.get(baseUrl + "/");
driver.findElement(By.linkText("Login")).click();
driver.findElement(By.name("email_address")).clear();
driver.findElement(By.name("email_address")).sendKeys("[email protected]");
driver.findElement(By.name("password")).clear();
driver.findElement(By.name("password")).sendKeys("Annie0308!");
driver.findElement(By.cssSelector("button.button")).click();
driver.findElement(By.linkText("Load Test1")).click();
driver.findElement(By.linkText("Manage Site")).click();
driver.findElement(By.linkText("Manage")).click();
driver.findElement(By.xpath("//div[@id='container']/div/table/tbody/tr[5]/td[6]/a")).click();
driver.findElement(By.linkText("Upload Logo")).click();
driver.findElement(By.name("image_file")).clear();
driver.findElement(By.name("image_file")).click();
// driver.findElement(By.name("image_file")).sendKeys("C:\\Users\\Janet\\Pictures\\P8291157.JPG");
setClipboardData("C:\\Users\\Janet\\Pictures\\P8291157.JPG");
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
// robot.delay(5000);
/* WebElement saveLink = driver.findElement(By.xpath("/html/body/div[12]/form/div/div[1]/button[1]"));
Actions actions = new Actions(driver);
actions.moveToElement(saveLink);
actions.click();
actions.build().perform(); */
JavascriptExecutor jse = (JavascriptExecutor)driver;
WebElement saveLink = driver.findElement(By.xpath("/html/body/div[12]/form/div/div[1]/button[1]"));
jse.executeScript("arguments[0].click();", saveLink);
// driver.findElement(By.cssSelector("button.submit.button")).click();
}
public static void setClipboardData(String string) {
StringSelection stringSelection = new StringSelection(string);
Toolkit.getDefaultToolkit().getSystemClipboard().setContents(stringSelection, null);
}
public void tearDown() throws Exception {
driver.quit();
}
}
终于可以使用了。这是完整的代码。必须使用 cssSelector 而不是 xpath:
Robot robot = new Robot();
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_ENTER);
Thread.sleep(3000);
robot.keyRelease(KeyEvent.VK_ENTER);
Thread.sleep(3000);
Thread.sleep(5000);
WebElement saveLink = driver.findElement(By.cssSelector("button.submit.button"));
Actions actions = new Actions(driver);
actions.moveToElement(saveLink);
actions.click();
actions.build().perform();
Thread.sleep(5000);
WebElement submitLink = driver.findElement(By.cssSelector("input.button"));
actions.moveToElement(submitLink);
actions.click();
actions.build().perform();
尝试下面的代码，它会起作用
uploadbutton = wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(uploadphotoelement)));
uploadbutton.click();
//Set the file path to be uploaded using Robot class
ss = new StringSelection(ProfileImagePath);
Toolkit.getDefaultToolkit().getSystemClipboard().setContents(ss, null);
robot = new Robot();
if(driver instanceof FirefoxDriver) {
// Press Enter to open the file upload dialog
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
}
// Wait for the file dialog to appear (time may vary)
robot.delay(1000);
// Paste the clipboard content (file path), I have uploaded the flower image from my locally saved pic.
robot.keyPress(KeyEvent.VK_CONTROL);
robot.keyPress(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_V);
robot.keyRelease(KeyEvent.VK_CONTROL);
// Press Enter to select the file
robot.keyPress(KeyEvent.VK_ENTER);
robot.keyRelease(KeyEvent.VK_ENTER);
