[已解決] warning: 请求失败 #181

Open bynum5566 opened 4 years ago

bynum5566 commented 4 years ago

問題概要：

瀏覽器可以連上leetcode.com，但Leetcode Editor不行

環境說明：

  1. 有防火牆管控的公司內網
  2. 無Win10系統管理者權限，只能用一般帳戶

流程敘述：

由於我沒有系統管理者無法安裝程式，所以下載了攜帶版的IDEA community IDEA裡面的MarketPlace無法搜尋任何plugin，猜測可能是防火牆問題所以我到這邊下載安裝包 之後手動安裝並且先輸入帳密，最後回到plugin UI點選地球圖示想觸發登入時發生錯誤： 下午 04:36 warning: 请求失败 這是唯一的Event Log，此外介面上沒有任何反應、沒有讀取到任何題目

Error Logs：

请求出错:

提問重點：

雖然說環境確實比較不便，不過我想弄清楚為什麼 plugin 登錄會報錯說443拒絕連線但瀏覽器不會呢？ 照理說瀏覽器也是走 443 port (HTTPS)去連線的，為何就能成功呢？ 我沒有掛任何代理或做任何客製化設定，基本上就是輸入帳密然後從UI操作而已 另外，我從5.4~6.4都嘗試過了，行為及log是一樣的... 再勞煩高手們幫忙分析一下了，我這樣還有機會繞過這問題嗎...謝謝、拜託了！

先安装一下plugin到6.4版本，然后再提供一下错误LOG. 通过Help -> Show Log in Explorer 查看日志，检查是否有 shuzijun 关键词，提供更详细的日志。

shuzijun

感謝回應，這是今天的日誌，啟動IDEA後只做了兩件事：1. plugin升級到6.4 2. 重新做出一次錯誤 裡面確實有關鍵字 shuzijun 关键词，再請看看有什麼線索，感謝您！

从日志上看，IDEA自身也无法链接到网络，但很奇怪的是你的浏览器是可以访问网络的。只能建议检查下是否是禁止了IDEA的联网，或者浏览器特殊配置了代理。
可以通过以下方式检查IDEA联网是否正常: 打开 File | Settings | Appearance & Behavior | System Settings | HTTP Proxy 打开 Check connection 输入 网址 检查是否可以正常访问

成功了，厲害！ 查了一下瀏覽器是套用Win10 global的proxy設定，此處被MIS設定了proxy URL 複製到IDEA內plugin設定代理的功能處：HTTP proxy>Automatic proxy configuration URL就可以使用！非常感謝給plugin設計了代理功能，要是沒這功能現在就不能繼續使用了～ 怎麼想到是代理問題的？太厲害，感謝 👯
