Java Selenium 超时页面

Question

我正在 selenium 中制作一个代理检查器，如果加载时间超过 15 秒，有什么方法可以让它进入下一个代理吗？

因此，如果它尝试第一个代理，则需要 15 秒或更长时间来加载，只需移至下一个代理

public class main {

    public static void main(String[] args) throws IOException, InterruptedException {
        BufferedReader br = new BufferedReader(new FileReader("proxy.txt"));
        String line;
        BufferedWriter file = null;
        file = new BufferedWriter(new FileWriter("proxy_out.txt"));


        while ((line = br.readLine()) != null) {
            //splitting
            String str;
            str = line;
            String[] splited = line.split(":");
            //System.out.println(Arrays.toString(splited));
            String IP = splited[0];
            String PORT = splited[1];
            System.out.println(IP + ":" + PORT);


            String PROXY = IP + ":" + PORT;
            org.openqa.selenium.Proxy proxy = new org.openqa.selenium.Proxy();
            proxy.setHttpProxy(PROXY)
                    .setFtpProxy(PROXY)
                    .setSslProxy(PROXY);
            DesiredCapabilities cap = new DesiredCapabilities();
            cap.setCapability(CapabilityType.PROXY, proxy);

            WebDriver driver = new ChromeDriver(cap);


            driver.get("google.com");
            try {
                WebElement Check = driver.findElement(By.id("input_captcha"));
                if (Check.isDisplayed()) {
                    System.out.println(PROXY + " is good");
                    file.write(IP+":"+PORT);
                }
            } catch (Exception e) {
                System.out.println("Bad");

            }
            driver.close();
        }
        file.close();
    }
}

您可以尝试使用如下所示的 WebDriverWait 类。

WebDriverWait wait = new WebDriverWait(driver, 15); //Timeout is 15 seconds
WebElement element = wait.until(ExpectedConditions.elementToBeSelected(By.id("input_captcha")));

此代码将不断尝试查找 input_captcha 元素，直到找到该元素或达到超时
