Question

我正在使用Selenium和GhostDriver以及PhantomJS从Java Webapp中截取网页页面。

我不知道为什么我会收到这个错误。我怀疑PhantomJSDriver正在使用服务器的公共IP，也许防火墙不满意......

该项目在我的本地计算机（OSX）上没有任何问题，但在服务器上没有任何问题（Debian 7）。

修改

我发现来自UnreachableBrowserException的主机和IP来自InetAddress.getLocalHost().getHostAddress()和InetAddress.getLocalHost().getHostName()。

超时实际上来自localhost地址Timed out waiting for [http://localhost:12518/status] to be available after 20010 ms。

Answer 1

我遇到了类似的问题，但即使消息很接近，也与暂停无关。实际上，这是因为ghost驱动程序无法创建其日志文件。

检查您的日志中是否有此消息，如果是，请尝试更改权限以进行检查。
