我已經正確地上傳了一個測試html頁面和servlet後面的this article。這工作,並會給我發一封電子郵件。但是,當我將這些代碼幾乎完全複製到下面顯示的代碼中的SendEmail方法中時,它不會發送電子郵件。我知道當我在本地運行它時,它會到達SendEmail方法(但是您無法使用GAE中的開發服務器發送電子郵件)。當我部署它時,頁面或日誌中沒有錯誤,所以它看起來好像只是不發送電子郵件。任何人都能看到原因?爲什麼我的谷歌應用程序引擎項目不發送電子郵件?

你怎麼知道它不發送**電子郵件? –
好吧,我假設因爲我發送給自己,我沒有收到它。 – Nick
您是否檢查過**垃圾郵件**文件夾? –
