如何使用 Selenium 在点击事件上下载文件?
我们可以使用 Selenium 在点击事件中下载文件。通常,点击下载链接时,会出现一个弹出框,其中包含文件名以及“打开”和“保存”选项。
要通过点击事件进行下载,需创建一个 FirefoxOptions 类对象。然后使用 addPreference 方法,我们配置浏览器首选项。
我们将提及下载位置与 neverAsk.openFile 和 neverAsk.saveToDisk 首选项设置。
示例
代码实现。
import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.firefox.FirefoxDriver; import org.openqa.selenium.firefox.FirefoxOptions; import java.util.concurrent.TimeUnit; public class FileDwnloadWithClick{ public static void main(String[] args) { System.setProperty("webdriver.gecko.driver", "C:\Users\ghs6kor\Desktop\Java\geckodriver.exe"); // create object of FirefoxOptions class FirefoxOptions profile = new FirefoxOptions(); // adding browser preferences with addPreference method profile.addPreference("browser.download.folderList", 2); // location of downloaded file profile.addPreference("browser.download.dir", "C:\Users\ghs6kor\Documents\Download"); profile.addPreference("browser.helperApps.neverAsk.openFile", "text/csv,application/x msexcel,application/excel," + "application/x-excel,application/vnd.ms-excel," + "image/png,image/jpeg,text/html,text/plain," + "application/msword,application/xml"); profile.addPreference("browser.helperApps.neverAsk.saveToDisk", "text/csv,application/x-msexcel," + "application/excel," + "application/x-excel," +"application/vnd.ms- excel,image/png,image/jpeg,text/html," +"text/plain,application/msword,application/xml"); // connecting browser options to webdriver WebDriver driver = new FirefoxDriver(profile); driver.get("https://the-internet.herokuapp.com/download"); //maximize window driver.manage().window().maximize(); // identify element and start download driver.findElement(By.linkText("xls-sample2.xls")).click(); } }
