我一直在做一个基于TV showTracker的示例，到目前为止我无法在我的网站上看到任何节目。我一直在努力尝试是否犯了一个错误，但我仍然找不到任何东西。那么如何检索这些信息。我已经将这个server.js和mongod分别放在不同的CMD中，并且在另一个CMD中吞噬了我仍然无法获得的任何节目。当我看到响应时，它会显示一个空白数组“[]”，就像这样。那么有什么建议？帮助将不胜感激。 （我已经主持了网站，认为这也有助于我的问题）。净调试错误表示API /表演/ - 响应= []为什么我从我的server.js文件得到空或[]响应？
这里是我的server.jsrespone

第1步：将您的代码缩减为[最小，完整且可验证的示例]（http://stackoverflow.com/help/mcve）。这样做的过程是询问这些问题时的基本准备，*通常*让你发现发现过程中出了什么问题，所以你甚至不需要问你的问题。然后如果你没有发现问题，你可以有更好，更小，更准确的代码来提问。 –
@ Mike'Pomax'Kamermans我责备这个链接到的博客帖子，因为它基本上构成了一个文件中的整个列表。但是基于OP的[上一个问题]（http://stackoverflow.com/questions/33472211/how-to-retreive-data-from-thetvdb-com）以及原始文章中缺乏细节和解释根本没有数据，或者至少它不在该代码尝试连接的同一个集合或数据库中。 –
@ Mike'Pomax'Kamermans对不起，我有点绝望得到答案。我一直在寻找答案，两天没有继续前进，我仍然看不到错误是什么，而不是他们的在线数据库，我检查了这一点。 –
