在警报Selenium Webdriver上单击“确定”(警报已触发)
好的,所以我知道关于webdriver警报的问题还有很多其他答案,我已经仔细研究了它们,但是我认为我的情况有所不同。当我单击“提交”按钮时,我已经切换到3帧,然后收到警报,因此我尝试切换回默认内容,然后使用try
catch和alert.accept单击警报,但仍然没有单击警报。代码如下。提前感谢你的帮助 :)
public class BookAHoliday { public FirstPage completeHolidayFormAndSubmit(String firstDate, String lastDate) { sleepsAreBad(); driver.switchTo().frame("ContainerFrame"); driver.switchTo().frame("iframeCommunityContainer"); driver.switchTo().frame("FORMCONTAINER"); fluentWait(By.id("StartDate_txtInput")); firstDayOfLeaveInput.sendKeys(firstDate); sleepsAreBad(); lastDayofLeaveInput.sendKeys(lastDate); try { submitButton.click(); } catch (UnhandledAlertException f) { try { sleepsAreBad(); driver.switchTo().defaultContent(); Alert alert = driver.switchTo().alert(); String alertText = alert.getText(); System.out.println("Alert data: " + alertText); alert.accept(); } catch (NoAlertPresentException e) { e.printStackTrace(); } } sleepsAreBad(); return PageFactory.initElements(driver, FirstPage.class); } private void sleepsAreBad() { try { Thread.sleep(5000); } catch (InterruptedException e) { e.printStackTrace(); } }public class BaseTest { public static WebDriver driver; static String driverPath = "C:\\"; @BeforeClass public static void setUp() { System.out.println("****************"); System.out.println("launching Browser"); System.out.println("****************"); // Browser selection //Firefox DesiredCapabilities dc = new DesiredCapabilities(); dc.setCapability(CapabilityType.UNEXPECTED_ALERT_BEHAVIOUR, UnexpectedAlertBehaviour.IGNORE); driver = new FirefoxDriver(dc);driver.get(URL); @AfterClass() public static void tearDown() { if (driver != null) { System.out.println("Closing browser"); driver.quit(); } }public class Bookings extends BaseTest{ @Test(description = "Holiday booking") public void CD01() { FirstPage firstPage = PageFactory.initElements(driver, FirstPage.class); firstPage .logIn("username", "password") .clickHolidayLink() .completeHolidayFormAndSubmit("12/05/2016", "15/05/2016"); }
警报框这是警报框
答案1
小编典典进入UnhandledAlertException
后尝试一下catch
WebDriverWait wait = new WebDriverWait(driver, 3000);wait.until(ExpectedConditions.alertIsPresent());Alert alert = webDriver.switchTo().alert();alert.accept();
可能会帮助您… :)
JavaSelenium Webdriver:修改navigator.webdriver标志以防止selenium检测
我正在尝试使用selenium和铬在网站中自动化一个非常基本的任务,但是以某种方式网站会检测到铬是由selenium驱动的,并阻止每个请求。我怀疑该网站是否依赖像这样的公开DOM变量https://stackoverflow.com/a/41904453/648236来检测selenium驱动的浏览器。
我的问题是,有没有办法使navigator.webdriver标志为假?我愿意尝试修改后重新尝试编译selenium源,但是似乎无法在存储库中的任何地方找到NavigatorAutomationInformation源https://github.com/SeleniumHQ/selenium
任何帮助深表感谢
PS:我还从https://w3c.github.io/webdriver/#interface尝试了以下操作
Object.defineProperty(navigator, ''webdriver'', { get: () => false, });
但是它仅在初始页面加载后更新属性。我认为网站会在执行脚本之前检测到变量。
答案1
小编典典从当前的实现开始,一种理想的访问网页而不被检测到的方法是使用ChromeOptions()该类向以下参数添加几个参数:
排除enable-automation
开关的集合
关掉 useAutomationExtension
通过以下实例ChromeOptions
:
Java示例:
System.setProperty("webdriver.chrome.driver", "C:\\Utility\\BrowserDrivers\\chromedriver.exe");ChromeOptions options = new ChromeOptions();options.setExperimentalOption("excludeSwitches", Collections.singletonList("enable-automation"));options.setExperimentalOption("useAutomationExtension", false);WebDriver driver = new ChromeDriver(options);driver.get("https://www.google.com/");
Python范例
from selenium import webdriveroptions = webdriver.ChromeOptions()options.add_experimental_option("excludeSwitches", ["enable-automation"])options.add_experimental_option(''useAutomationExtension'', False)driver = webdriver.Chrome(options=options, executable_path=r''C:\path\to\chromedriver.exe'')driver.get("https://www.google.com/")
Selenium WebDriver 在导入 selenium 时不可调用错误但在不导入 selenium 时有效
如何解决Selenium WebDriver 在导入 selenium 时不可调用错误但在不导入 selenium 时有效?

我尝试了许多不同的方法来尝试让 webdriver.Chrome()
工作,但没有任何运气。我曾尝试使用 Chrome (chromedriver) 和 Firefox (geckodriver),尝试以多种不同的方式加载 selenium
包,但我一直收到错误 TypeError: ''WebDriver'' object is not callable
。
我下面的原始代码仍然有效。 (即它会打开 Google Chrome 浏览器并转到 my_profiles_list
中的每个配置文件,但我想使用上面的代码。
from datetime import datetime
from scrape_linkedin import ProfileScraper

# Find and copy the li_at value
myLI_AT_Key = ''INSERT LI_AT Key''
with ProfileScraper(cookie=myLI_AT_Key,scroll_increment = 50,scroll_pause = 0.8) as scraper:
for link in my_profile_list:
print(''Currently scraping: '',datetime.Now())
profile = scraper.scrape(url=link)
dataJSON = profile.to_dict()
profileName = re.sub(''https://www.linkedin.com/in/'',link)
profileName = profileName.replace("?originalSubdomain=es","")
profileName = profileName.replace("?originalSubdomain=pe","")
profileName = profileName.replace("?locale=en_US","")

profileName = profileName.replace("?originalSubdomain=uk","")

json.dump(dataJSON,json_file)
time.sleep(10)

注意事项:
代码略有不同,因为我在 SO here 上提出了一个问题,@Ananth 帮助我给出了解决方案。
我也知道在线和 SO 存在与 selenium
和 chromedriver
相关的“类似”问题,但在尝试了每个建议的解决方案后,我仍然无法使其正常工作。 (即常见的解决方案是 webdriver.Chrome()
中的拼写错误)。

Selenium WebDriver-Java-单击一个按钮
我试图单击一些按钮,并以抽搐为例使用“跟随”按钮。
我使用Selenium IDE尝试获取按钮的xpath。我得到的xpath是://span[@id=''ember637'']/a/span
如果我转到FireFox并为按钮复制唯一选择器,则会得到: .js-follow > span:nth-child(1)
我在Java程序中都尝试过,但它们都无效。当我使用//span[..
xpath时,出现以下错误:
"Unable to locate a node using //span[@id=''ember637'']/a/span"
编辑:
我要单击的带有按钮的网站示例(“关注”按钮):http :
//www.twitch.tv/mradder89/profile/
我正在使用的Selenium jar文件是“ selenium-server-standalone-2.35.0.jar”
我得到的错误是
"Exception in thread "main" org.openqa.selenium.NoSuchElementException: Unable to locate a node using //span[@id=''ember637'']/a/span"
编辑2:
我下载了PhantomJSDriver
exe文件(phantomjs.exe)并正在尝试。它不起作用…我没有收到像以前一样的错误消息(“无法找到节点…”错误)。
这是代码:http :
//pastebin.com/GzvubMZr
答案1
小编典典使用PhantomJSDriver,尝试其他定位器。如果有异常,则发布异常,否则,发布异常信息,例如位置,文本等。
driver.findElement(By.xpath("//*[contains(@class, ''profile-actions'')]//span[text()=''Follow'']")).click();driver.findElement(By.cssSelector(".profile-actions .primary_button > span")).click();
Selenium Webdriver-单击隐藏的元素
我正在尝试自动执行Google云端硬盘中的上传文件功能。
用于传递参数的元素以高度-0px隐藏。
用户操作均不会使该元素可见。因此,我需要一种变通方法来在不可见的元素上单击。
<input type="file"multiple=""/>
上述元素的xpath是-
//*[@goog-menu goog-menu-vertical uploadmenu density-tiny'']/input
我在用
WebDriver.findElement(By.xpath(<xpath>).sendKeys(<uploadFile>)
例外-
org.openqa.selenium.ElementNotVisibleException
- 元素当前不可见,因此可能无法与之交互。
我尝试使用JavascriptExecutor。但是找不到确切的语法。
答案1
小编典典试试这个:
WebElement elem = yourWebDriverInstance.findElement(By.xpath("//*[@goog-menu goog-menu-vertical uploadmenu density-tiny'']/input"));String js = "arguments[0].style.height=''auto''; arguments[0].style.visibility=''visible'';";((JavascriptExecutor) yourWebDriverInstance).executeScript(js, elem);
上面的那堆将改变文件输入控件的可见性。然后,您可以继续执行文件上传的常规步骤,例如:
elem.sendKeys("<LOCAL FILE PATH>");
请注意,通过更改输入字段的可见性,您可以干预要测试的应用程序。注入脚本来改变行为是侵入性的,在测试中不建议这样做。
