所以我試圖部署我的python燒瓶應用程序到一個Ubuntu的AWS EC2實例。我已經設置mod_wsgi，配置虛擬主機設置一個virtualenv和創建別名服務器我的靜態文件。出於某種原因，我不能讓我的API自定義路徑返回正確的信息。我試過了我到處搜索的所有東西，這是我的最後一個選擇。燒瓶路線返回500錯誤

任何幫助理解。
這裏是一個捲曲的請求從我個人的機器跑到主機

<h1>Internal Server Error</h1>
<p>The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.</p>
這裏是捲曲要求使用本地主機的請求從主機跑到主機。

可以使用捲曲輸出顯示請求和響應？本地或遠程使用@ kracekumar – Kracekumar
，例如從服務器或從我的個人機器？ – djowinz
服務器輸出。 – Kracekumar
