我一直在做一個基於TV showTracker的示例，到目前爲止我無法在我的網站上看到任何節目。我一直在努力嘗試是否犯了一個錯誤，但我仍然找不到任何東西。那麼如何檢索這些信息。我已經將這個server.js和mongod分別放在不同的CMD中，並且在另一個CMD中吞噬了我仍然無法獲得的任何節目。當我看到響應時，它會顯示一個空白數組「[]」，就像這樣。那麼有什麼建議？幫助將不勝感激。 （我已經主持了網站，認爲這也有助於我的問題）。淨調試錯誤表示API /表演/ - 響應= []爲什麼我從我的server.js文件得到空或[]響應？
這裏是我的server.jsrespone

第1步：將您的代碼縮減爲[最小，完整且可驗證的示例]（http://stackoverflow.com/help/mcve）。這樣做的過程是詢問這些問題時的基本準備，*通常*讓你發現發現過程中出了什麼問題，所以你甚至不需要問你的問題。然後如果你沒有發現問題，你可以有更好，更小，更準確的代碼來提問。 –
@ Mike'Pomax'Kamermans我責備這個鏈接到的博客帖子，因爲它基本上構成了一個文件中的整個列表。但是基於OP的[上一個問題]（http://stackoverflow.com/questions/33472211/how-to-retreive-data-from-thetvdb-com）以及原始文章中缺乏細節和解釋根本沒有數據，或者至少它不在該代碼嘗試連接的同一個集合或數據庫中。 –
@ Mike'Pomax'Kamermans對不起，我有點絕望得到答案。我一直在尋找答案，兩天沒有繼續前進，我仍然看不到錯誤是什麼，而不是他們的在線數據庫，我檢查了這一點。 –
