我正在使用新的chrome驱动程序无头模式(Chrome v59，mac os(与网络驱动程序。 但不幸的是，在无头模式下给出的屏幕截图选项对我不起作用。 以下代码显示了配置的镶边选项。
chromeOptions.addArguments("headless");
chromeOptions.addArguments("disable-gpu");
chromeOptions.addArguments("window-size=1980x960");
chromeOptions.addArguments("screenshot");
我收到未知的铬错误：

window-size参数需要字符串格式800,600，请尝试以下操作：
chromeOptions.addArguments("window-size=1980,960");
另外，您的screenshot论点中有一个错字：
chromeOptions.addArguments("screenshot");
