通過節點JS和Sequelize連接到MySql

-1

當我嘗試從節點連接到運行在同一臺計算機（debian）上的MySql數據庫時，使用特定的用戶和密碼，我得到「訪問被拒絕」錯誤。如果我嘗試使用相同的用戶並在數據庫和節點中設置無密碼，則一切正常。通過節點JS和Sequelize連接到MySql

從終端的WITH口令也連接工作正常。我已經嘗試刪除用戶和數據庫並重新創建它們。但沒有任何工作。

這是我的節點代碼：

var http = require('http'); 
var fs = require('fs'); 
var Sequelize = require('sequelize') 
var sequelize = new Sequelize('mysql://user:[email protected]:3306/databasename'); 

http.createServer(function (req, res) { 
    console.dir(req.url); 
    sequelize.query("SELECT @@version;").spread(function(results, metadata) { 
     console.log(results); 
    }) 

    res.writeHead(200, {'Content-Type': 'text/html'}); 

    res.end('ok'); 
}).listen(8080);

什麼我得到的控制檯上是這樣的：

任何線索？

密碼是否包含可能導致在URI中使用的問題的字符？百分號，＆號，加號等 – robertklep

不，沒有那樣的。我嘗試了與mysqljs相同，並得到相同的錯誤... – CPlusPlus

因此'mysql -uuser -p databasename'的作品（輸入密碼後）？ – robertklep

好的，問題是，package.json不包含依賴項（mysql或sequelize）。我仍然不知道，爲什麼我可以連接到沒有密碼的數據庫。但現在它工作。
