Question

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，但有一些奇怪的错误。

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]);
    });
});

然而，当我尝试打开我的应用时，它已经崩溃了...... 这是我的Heroku日志：

Answer 1

你的变量人没有逗号。

 password: "37eb78b5"<missing comma>
database: 'heroku_1d0d2358c241fd0'

下次您可以看到错误日志并进行调试。
