BrowserMob代理警告和异常java.io.IOException：由peer重置连接

时间：2015-10-13 20:53:45

标签： java remotewebdriver browsermob

我正在使用BrowserMob代理接口版本2.1.0-beta-3（最新版本）和RemoteWebDriver，并且在运行它时会定期看到以下警告/异常。当驱动程序尝试导航到URL时，似乎远程端停止/崩溃/关闭连接。但是，我并没有真正得到可能导致它关闭的东西。

大部分时间执行仍在继续，它实际导航到所需的URL并捕获HAR，但有时它会挂起，之后我必须终止该过程。

另外，如果我让这个过程继续运行一段时间，请不断收到这些错误。这似乎是一个SSL证书问题，但它通常背负着第一个问题。

一直在观察这些例外，虽然我认为它们与broswermob无关或可能

我尝试在网上查找和搜索，但似乎没有一个好的解决方案。任何建议或方向都会非常有帮助。

答案 0 :(得分：0)

您已经在日志中提到了几个不同的异常。如果 连接由同行重置 ，那么我也会看到很多。我还没有确认这一点，但我确实有一个关于造成这种情况的理论。

我正在运行加载许多页面的测试套件。当第一页测试完成后，它会加载下一页。但是，当它执行此操作时，仍可能存在正在进行的网络请求。当Web浏览器请求新页面时，仍然打开的连接会发生什么？我怀疑浏览器在继续之前关闭了这些连接。这将导致BrowserMob Proxy获得意外的关闭连接事件。当它发生时，它可能会抛出 连接重置由对等 异常，然后被记录。

如果是这种情况，那么这可能不是问题。应该可以创建一些测试场景来证明这一点。
