与JAVA与Selenium browsermob不起作用，浏览器的不同错误

Question

我使用Java与硒，我想使用browsermob：我使用相同的代码为不同的浏览器，例如火狐：

 BrowserMobProxyServer proxyServer = new BrowserMobProxyServer(); 
     proxyServer.start(); 
     proxyServer.setHarCaptureTypes(CaptureType.getAllContentCaptureTypes()); 
     proxyServer.enableHarCaptureTypes(CaptureType.REQUEST_CONTENT, CaptureType.RESPONSE_CONTENT); 
     Proxy proxy = ClientUtil.createSeleniumProxy(proxyServer); 
     DesiredCapabilities dccFirefox = DesiredCapabilities.firefox(); 
     dccFirefox.setCapability(CapabilityType.PROXY, proxy); 
     this.driver = new FirefoxDriver(dccFirefox); 

发生在Firefox错误：

开启Chrome normaly，但网页无法打开，在控制台出现错误：

Failed to load resource: net::ERR_EMPTY_RESPONSE 
net::ERR_PROXY_CONNECTION_FAILED 

有人有任何想法，为什么这样的错误发生？

Geckodriver存在一个公开问题，导致此问题。 https://github.com/mozilla/geckodriver/issues/764

您可以使用下面的代码获得解决方法。

由于geckodriver不可信设置已经改变。所以更新的代码，以适应同一
