Question

当我尝试从节点连接到在同一台机器（debian）上运行的MySql数据库时，使用特定的用户和密码，我得到一个＆＃34;访问被拒绝＆＃34;错误。如果我尝试使用相同的用户并在数据库和节点中没有设置密码，那么一切正常。

终端与密码的连接也正常。我已经尝试删除用户和数据库并重新创建它们。但没有任何作用。

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:password@localhost: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);

我在控制台上得到的是：

任何线索？

好的，问题是，package.json不包含依赖项（mysql或sequelize）。我还是不知道，为什么我可以在没有密码的情况下连接到数据库。但现在它有效。

使用Node JS和Sequelize连接到MySql
