BrowserMob代理警告和異常java.io.IOException：對等重置連接

[英]BrowserMob Proxy warning and exception java.io.IOException: Connection reset by peer

 原文  2015-10-13 20:53:44  3   1    java/ remotewebdriver/ browsermob

問題描述

我正在將BrowserMob代理接口版本2.1.0-beta-3（最新）與RemoteWebDriver一起使用，並且在運行它時經常看到以下警告/異常。 在驅動程序嘗試導航到URL時，似乎遠端已停止/斷開/關閉了連接。 但是我並沒有真正了解可能導致它關閉的原因。

大多數情況下，執行會繼續進行，並且實際上會導航到所需的URL並捕獲HAR，但是有時它只是掛起，之后我必須終止該過程。

另外，如果我讓進程運行更多時間，請繼續獲取這些錯誤。 這似乎是SSL證書問題，但通常會附帶第一個證書。

我嘗試過在線查找和搜索，但似乎沒有很好的解決方案。 任何建議或指示將非常有幫助。

您已經提出了幾種在日志中看到的異常。 在由peer重置Connection的情況下，我也看到了很多。 我還無法確認這一點，但是我確實有造成這種情況的理論。

我正在運行加載許多頁面的測試套件。 當首頁測試完成時，它將加載下一頁。 但是，這樣做時可能仍在進行網絡請求。 當網絡瀏覽器請求一個新頁面時，仍然打開的連接又會怎樣？ 我懷疑瀏覽器在繼續之前會關閉這些連接。 這將導致BrowserMob代理獲得意外的關閉連接事件。 在執行此操作時，它可能會引發對等異常重置連接 ，然后將其記錄下來。

如果是這種情況，則可能不是問題。 應該可以創建一些測試場景來證明這一點。
