基本上，我在 Heroku 上部署了一个应用程序。现在，我正在尝试连接 ClearDB 附加组件，但出现一些奇怪的错误。
这是我的 Heroku 配置:
C:\Users\GDrAnimal\Self-Project\Facebook Bot>heroku config
=== arcane-forest-17003 Config Vars
DATABASE_URL: mysql://b9490a25809735:37eb78b5@us-cdbr-iron-east-05.cleardb.net/heroku_1d0d2358c241fd0?reconnect=true
这是我使用 Nodejs 的代码
var mysql = require('mysql');
//Database
var connection = mysql.createConnection({
host: "us-cdbr-iron-east-05.cleardb.net",
user: "b9490a25809735",
password: "37eb78b5"
database: 'heroku_1d0d2358c241fd0'
});
connection.connect();
app.get('/', (req, res) => {
connection.query('SELECT * from Student_Bot', function(err, rows, fields) {
if (err) {
console.log('Error Reported ', err);
throw err;
}
res.send(['Hello World!!!! HOLA MUNDO!!!!', rows]);
});
});
但是，当我尝试打开我的应用程序时，它崩溃了...... 这是我的 Heroku 日志:

最佳答案
变量 man 中没有逗号。
password: "37eb78b5"<missing comma>
database: 'heroku_1d0d2358c241fd0'
下次您可以查看错误日志并进行调试。
