在Java中使用Selenium Web驱动程序，我试图通过点击应用程序中的链接来下载文件。
即。单击链接时，应该开始下载而不询问是否使用Firefox 12浏览器保存文件。
我正在使用browser.helperApps.neverAsk.saveToDisk方法。
实际结果：
当我运行此代码时，文件不会自动保存，而是要求保存或不保存。我使用数据驱动的方法，我从Excel文件中获取元素。
有人可以帮帮我吗？
以下是使用browser.helperApps.neverAsk.saveToDisk的代码
public class Driver {
static WebDriver driver;
public static void main(String[] args) {
FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("browser.download.folderList", 2);
profile.setPreference("browser.download.dir", "d:\\");
profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "application/vnd.ms-excel");
driver = new FirefoxDriver(profile);
driver.get("https://www.testapp.com");
driver.manage().timeouts().implicitlyWait(20, TimeUnit.SECONDS);
TestRunner.run(suiteToRun());
}
public static Test suiteToRun(){
TestSuite suite = new TestSuite();
System.out.println("Login Class");
suite.addTestSuite(LoginLogout.class);
return suite;
}
}

可能内容类型application/vnd.ms-excel不正确。
使用以下代码尝试列出all content-types：
public class Driver {
static WebDriver driver;
public static void main(String[] args) {
FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("browser.download.folderList", 2);
profile.setPreference("browser.download.dir", "d:\\");
profile.setPreference("browser.helperApps.neverAsk.saveToDisk",
