Mongoose连接然后立即断开（Node.js + Express）
我有一个使用Mongoose连接到MongoDB的Express（Node.js）应用程序。 在过去的几周里，它一直在运转良好，但在过去的几天里，这让我疯狂。
服务器似乎连接到MongoDB，然后立即断开连接。 从global日志：

你可以看到这一切都是从同一秒。
我如何连接：
var mongoose = require('mongoose'); mongoose.connect('mongodb://MY_USERNAME:MY_PASSWORD@127.0.0.1:27017/MY_DB_NAME'); mongoose.connection.on('open', function (ref) { console.log('Connected to mongo server.'); }); mongoose.connection.on('error', function(err) { console.info('Error: Could not connect to MongoDB. Did you forget to run `mongod`?'); console.log(err); });
服务器日志Connected to mongo server. 。 这是从哪里来的？
我做了一个全新的安装，这是相同的，所以我想这一定是我的代码。 有没有其他的代码我应该粘贴？
感谢任何帮助家伙。
遵循Jameson的build议，我将var appCon = mongoose.createConnection(url)更改为var appCon = mongoose.createConnection(url) 。 检查日志，实际上似乎使连接坚持。 奇怪的。
.connect显然不是这个问题的根源。 我没有足够的信息。
我如何检查“引擎盖下”？
那好..这很尴尬。 我实际上已经离开了mongoose.connection.close(); 在一个文件的底部，当我想要连接是dynamic的，只有当我需要时才打开。
这实际上花了3天才find。 多浪费时间！
谢谢你的时间。
尝试
var appConnection = mongoose.createConnection('mongodb://127.0.0.1:27017/bookAPI'); appConnection.on('error', console.error.bind(console, 'connection error:')); appConnection.once('open', function callback () { console.log("h"); });
