硒:清除Chrome缓存 [英] Selenium: Clear chrome cache

问题描述

在我的应用程序中，我需要一种方法在注销之前仅清除chrome浏览器的缓存(cookie除外-我不想删除cookie).

In my application I need a way to clear only the cache of the chrome browser before log out (except cookies - I do not want to delete cookies).

有人可以建议我单击Chrome中的清除数据"按钮的方法吗? 我已经编写了以下代码，但是该代码无法正常工作.

Can any one suggest me a way to click on the CLEAR DATA button in chrome. I have written the below code but the code is not working.

配置:

Chrome版本:65.0.3325.181版(正式内部版本)(64位)

Chrome Version: Version 65.0.3325.181 (Official Build) (64-bit)

硒版本:3.11.0

Selenium Version: 3.11.0

//Clear the cache for the ChromeDriver instance.
driver.get("chrome://settings/clearBrowserData");
Thread.sleep(10000);
driver.findElement(By.xpath("//*[@id='clearBrowsingDataConfirm']")).click();

推荐答案

您在这里使用

driver.findElement(By.xpath("//*[@id='clearBrowsingDataConfirm']")).click();

不幸的是，这无法正常工作，因为Chrome设置页面使用 Polymer 和 WebComponents ，需要通过/deep/组合器使用查询选择器，因此该选择器情况是* /deep/ #clearBrowsingDataConfirm.

Unfortunately, this won’t work because the Chrome settings page uses Polymer and WebComponents, need to use query selector using the /deep/ combinator, so selector in this case is * /deep/ #clearBrowsingDataConfirm.

这是解决您的问题的方法...您可以使用以下任一方法来实现相同的目标...

Here is workaround to your problem...you can achieve the same using either one of the following...

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.Test;

public class ClearChromeCache {

    WebDriver driver;

    /*This will clear cache*/
    @Test
    public void clearCache() throws InterruptedException {
        System.setProperty("webdriver.chrome.driver","C://WebDrivers/chromedriver.exe");
        ChromeOptions chromeOptions = new ChromeOptions();
        chromeOptions.addArguments("disable-infobars");
        chromeOptions.addArguments("start-maximized");
        driver = new ChromeDriver(chromeOptions);
        driver.get("chrome://settings/clearBrowserData");
        Thread.sleep(5000);
        driver.switchTo().activeElement();
        driver.findElement(By.cssSelector("* /deep/ #clearBrowsingDataConfirm")).click();
        Thread.sleep(5000);
    }

    /*This will launch browser with cache disabled*/
    @Test
    public void launchWithoutCache() throws InterruptedException {
        System.setProperty("webdriver.chrome.driver","C://WebDrivers/chromedriver.exe");
        DesiredCapabilities cap = DesiredCapabilities.chrome();
        cap.setCapability("applicationCacheEnabled", false);
        driver = new ChromeDriver(cap);
    }
}
