Question

我尝试使用机械手类保存图像...但是无法正常工作。

    WebDriver driver = new FirefoxDriver();
    driver.manage().window().maximize();
    driver.get("http://agiletesters.com.br");
     Robot rb =new Robot();
     rb.mouseMove(270, 160);
     rb.mousePress(InputEvent.BUTTON3_DOWN_MASK);
     rb.mouseRelease(InputEvent.BUTTON3_DOWN_MASK);

     rb.keyPress(KeyEvent.VK_DOWN);
     Thread.sleep(11000);
     rb.keyRelease(KeyEvent.VK_DOWN);
     rb.keyPress(KeyEvent.VK_ENTER);
     rb.keyRelease(KeyEvent.VK_ENTER);

在此右键单击中有效，但未选择“将图像另存为...”选项。

我尝试了此操作，但下载图像未显示：-

try {
         driver = new FirefoxDriver();
         driver.get("http://agiletesters.com.br");
         System.setProperty("http.agent", "Firefox");
         WebElement logo = driver.findElement(By.xpath("//*[@id=\"header-menu\"]/div/div[1]/a/img"));
         String logoSRC = logo.getAttribute("src");

         URL imageURL = new URL(logoSRC);
         BufferedImage saveImage = ImageIO.read(imageURL.openStream());

         ImageIO.write(saveImage, "png", new File("logo-forum.png"));

         } catch (Exception e) {
            e.printStackTrace();
         } finally {
            driver.close();
         }

我的期望是您的BufferedImage saveImage = ImageIO.read(imageURL.openStream());由于缺少Cookie header而失败

下载文件的正确方法是：

使用driver.managet().getCookies() function
使用基础OKHTTP library to execute the GET request作为徽标并保存文件。

示例代码：

OkHttpClient client = new OkHttpClient().newBuilder().build();

Request request = new Request.Builder().url(logoSRC).addHeader("Cookie", cookies.toString()).build();
Response response = client.newCall(request).execute();

File downloadedLogo = new File("logo-forum.png");
BufferedSink sink = Okio.buffer(Okio.sink(downloadedLogo));
sink.writeAll(Objects.requireNonNull(response.body()).source());
sink.close();

使用机器人课怎么能保存图片？
