java – 在Selenium HtmlUnitDriver程序中捕获的SocketException

前端之家收集整理的这篇文章主要介绍了java – 在Selenium HtmlUnitDriver程序中捕获的SocketException前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

我写了一个小脚本,它接受我们公司收到的Epson打印机的默认IP地址,并根据要求自动更改.这是使用Selenium HtmlUnitDriver完成的.

脚本获取页面,插入新IP,然后提交它.因为一旦我们第二次提交IP就会更改,页面不再是192.168.192.168,并且脚本不想完成.

以下是脚本:

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.htmlunit.HtmlUnitDriver;

public class Main {
    public static void main(String[] args) {

        // Creating a new instance of the HTML unit driver.
        WebDriver driver = new HtmlUnitDriver();
        driver.get("http://192.168.192.168/ctcpip.htm");

        // Find and change the IP Address field.
        WebElement element = driver.findElement(By.name("IpAddress"));
        element.clear();
        element.sendKeys("192.168.192.169");
        element.submit();

        // Reset the printer. This changes it's IP as well,causing the initial driver page to no longer exist.
        WebElement reset = driver.findElement(By.name("Submit"));
        reset.submit();

        // The script never gets this far.
        driver.quit();

    }
}

脚本在完成之前会超时.单击reset元素时,http://192.168.192.168/ctcpip.htm的初始URL实际上不存在,因为我们已将其更改为192.169.192.169.这是预期的行为,也是整个计划的重点.

Process finished with exit code 1

如何告诉我的驱动程序实例页面已经更改,以便进程可以正常退出

脚本需要到达driver.quit();线.

最佳答案
你试过电话吗?

driver.quit();

之前

reset.submit();

?您不再使用驱动程序来检索任何元素,因此您可以在提交页面之前退出.

我希望它有所帮助.
