通过节点JS和Sequelize连接到MySql

-1

当我尝试从节点连接到运行在同一台计算机（debian）上的MySql数据库时，使用特定的用户和密码，我得到“访问被拒绝”错误。如果我尝试使用相同的用户并在数据库和节点中设置无密码，则一切正常。通过节点JS和Sequelize连接到MySql

从终端的WITH口令也连接工作正常。我已经尝试删除用户和数据库并重新创建它们。但没有任何工作。

这是我的节点代码：

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);

什么我得到的控制台上是这样的：

密码是否包含可能导致在URI中使用的问题的字符？百分号，＆号，加号等 – robertklep

不，没有那样的。我尝试了与mysqljs相同，并得到相同的错误... – CPlusPlus

因此'mysql -uuser -p databasename'的作品（输入密码后）？ – robertklep

好的，问题是，package.json不包含依赖项（mysql或sequelize）。我仍然不知道，为什么我可以连接到没有密码的数据库。但现在它工作。
