服務器關閉了連接

Question

我想要的Node.js和MySQL，但即時收到此錯誤：

:Error: Connection lost: The server closed the connection. my code here.

var mysql = require('mysql'); 
var config = { 
    connectionLimit: 100, 
    waitForConnections: true, 
    queueLimit: 0, 
    debug: true, 
    wait_timeout: 28800, 
    connect_timeout: 10, 
    host: "localhost", 
    user: " root ", 
    password: " root ", 
    database: "mydb" 
}; 
var table = 'mytable'; 
var connection; 

function handleConnection() { 
    connection = mysql.createConnection(config); 
    connection.connect(function(err) { 
     console.log("connected"); 
    }); 
    connection.query('select * from' + table, 
     function(err, result, fields) { 
      if (!err) { 
       console.log("result :" + result); 
      } else { 
       console.log("error1 :" + err); 
      } 
     }); 
}

在你的代碼行

connection.query('select * from' + table,

將解析如下：

select * frommytable

由於沒有spac e在'from'關鍵字之後。嘗試在'from'之後添加空格字符。

而且在配置，你之前和之後的用戶名和密碼的值增加一個空格字符：

user : " root ", password : " root ",
