使用Firefox的硒自动化在本地可以运行，但是在服务器上无法运行

硒版本：3.141.59

Geckodriver版本：0.24.0

Firefox版本：68.0.1

JDK版本：1.8.0_171

本地JRE版本：1.8.0_211

服务器JRE版本：1.8.0_191

例外：

我正在以无头模式启动Firefox。在本地工作正常，但在Windows服务器上出现上述错误。

代码：

FirefoxProfile profile = new FirefoxProfile(); 
    profile.setPreference("capability.policy.default.Window.QueryInterface", "allAccess"); 
    profile.setPreference("capability.policy.default.Window.frameElement.get","allAccess"); 
    profile.setPreference("browser.download.folderList", 2);
    profile.setPreference("browser.download.dir", System.getProperty("user.dir")+"\\downloads");
    profile.setPreference("browser.download.useDownloadDir", true);
    profile.setAcceptUntrustedCertificates(true); 
    profile.setAssumeUntrustedCertificateIssuer(true); 
    DesiredCapabilities capabilities = new DesiredCapabilities();
    FirefoxOptions options = new FirefoxOptions();
    options.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
    options.setCapability("marionatte", false);
    options.setProfile(profile);
    options.setHeadless(true);
    options.setBinary(browserBinary);   
    options.addPreference("browser.helperApps.neverAsk.saveToDisk", "text/csv");
    options.addPreference("pdfjs.disabled", true);  

    log.info("Starting firefox");
    FirefoxDriver driver = new FirefoxDriver(options);
    driver.getCapabilities().merge(capabilities);

我之前尝试过chromedriver，它在本地和服务器上都能很好地工作。但是我想使用Firefox以无头模式下载文件。

您需要在-FirefoxOptions options = new FirefoxOptions（）;之后启动RemoteDriver。

driver = new RemoteWebDriver(your URL, capabilities);

使用Firefox的Selenium自动化在本地工作，但在服务器上失败
