Go App中的Google App Engine自定義IP端口

我想在Go的GAE上創建一個Web應用程序，我需要它來收聽自定義端口。我如何設置它？我試圖用http.ListenAndServe（「12345」，無）在沙箱中，但在我的控制檯得到這個：Go App中的Google App Engine自定義IP端口

你不能做到這一點。 App Engine不允許自定義http端口。 App Engine環境存在很大的沙盒問題，並非您在Pure Go（或Java或Python）中可以做的所有事情都可以在各自的App Engine環境中使用。

從http://code.google.com/appengine/docs/go/overview.html：

由於與Java和Python的環境中，並非所有的標準庫的功能是可用的沙箱內。例如，嘗試打開套接字或寫入文件將返回os.EINVAL錯誤。

Go應用程序在一個安全的「沙箱」環境中運行，其庫集合減少。例如，應用程序無法將數據寫入本地文件系統或進行任意網絡連接。相反，應用程序使用App Engine提供的可擴展服務來存儲數據並通過Internet進行通信。

嗯，我可以看到我能做出的請求GAE中的非標準端口：http：//code.google.com/appengine/docs/go/urlfetch/overview.html。我應該如何在Go中獲取我自己的地址以獲取HTTP請求，以及當有人爲該地址調用錯誤的端口（它沒有通過或者被轉發到正常端口）時會發生什麼？ – ThePiachu

你現在問完全不同的問題。在你原來的問題中，你問過關於在App Engine上的非標準端口上執行http服務器。本頁面討論瞭如何執行http客戶端請求。不同的東西。 IP地址是計算機的屬性，而不是Go。您無法選擇App Engine服務器的IP地址，Google會在您選擇的服務器之間彈出您的App Engine代碼。他們會給你一個穩定的DNS名稱。連接到App Engine上的非http端口很可能被拒絕。 –
