NodeJS使用node-mssql连接到sql server不起作用

Question

我使用 SQL Server Express 2012 的命名实例 如果我尝试使用 SSMS 连接到它，则可以使用以下参数：

Server name: mit-007\SQLEXPRESS2012
Authentication: SQL Server Authentication
    Login: sa
    Password: mit

使用 node-mssql：

var sql = require('mssql');
var config = {
    user: 'sa',
    password: 'mit',
    server: 'mit-007',
    driver: 'tedious',
    database: 'Delvi',
    options: {
        instanceName: 'SQLEXPRESS2012'
    }
};

sql.connect(config).then(function(){ // and so on

它会记录这个错误

{ [ConnectionError: Failed to connect to mit-007:undefined in 15000ms]
  name: 'ConnectionError',
  message: 'Failed to connect to mit-007:undefined in 15000ms',
  code: 'ETIMEOUT' }

Answer 1

我认为mit-007 不是您的网络地址。

Answer 2

浏览后我解决了问题，这就是我所做的

1. 打开 SQL Server 配置管理器
2. 单击 SQL Server 网络配置 => SQLEXPRESS2012 的协议
3. 双击 TCP/IP
4. 将启用更改为是
5. 点击 IP 地址
6. IPAll => 清除 TCP 动态端口，设置 TCP 端口 1433
7. 打开 services.msc
8. 启动 SQL Server Browser 服务
9. 重启 SQL Server

我不确定上述每一个步骤是否都是必要的，但它们对我有用

繁琐的驱动逻辑中存在一个缺陷，表明在 mac 平台上运行时端口“未定义”。

在 MS Windows 平台上使用以下配置设置时，程序 (testtedious.js) 运行良好：

var connectionConfig = {
    userName: 'xxx',
    password: 'yyy',
    database: 'zzz',
    server: '127.0.0.1',
    port: 1443,
    debug: true,
    driver: 'tedious',
    options: {
        encrypt: false,
        instanceName: 'SQLEXPRESS',
        database: 'www',
        useColumnNames: false,
        debug: {
            packet: true,
            data: true,
            payload: true,
            token: true,
            log: true
        }
    }
};

但是，在 mac 上运行时出现以下错误：

$ node testtedious.js
Tedious-Connection-Pool: filling pool with 2
Tedious-Connection-Pool: creating connection: 1
Tedious-Connection-Pool: creating connection: 2
Tedious-Connection-Pool: connection connected: 1
Tedious-Connection-Pool: connection closing because of error
{ ConnectionError: Failed to connect to 127.0.0.1:undefined in 15000ms
    at ConnectionError (/project-dir/node_modules/tedious/lib/errors.js:12:12)
    at Connection.connectTimeout (/project-dir/node_modules/tedious/lib/connection.js:467:28)
    at ontimeout (timers.js:365:14)
    at tryOnTimeout (timers.js:237:5)
    at Timer.listOnTimeout (timers.js:207:5)
  message: 'Failed to connect to 127.0.0.1:undefined in 15000ms',
  code: 'ETIMEOUT' }
Tedious-Connection-Pool: connection connected: 2
Tedious-Connection-Pool: connection closing because of error
{ ConnectionError: Failed to connect to 127.0.0.1:undefined in 15000ms
    at ConnectionError (/project-dir/node_modules/tedious/lib/errors.js:12:12)
    at Connection.connectTimeout (/project-dir/node_modules/tedious/lib/connection.js:467:28)
    at ontimeout (timers.js:365:14)
    at tryOnTimeout (timers.js:237:5)
    at Timer.listOnTimeout (timers.js:207:5)

  code: 'ETIMEOUT' }
Tedious-Connection-Pool: creating connection: 3
Tedious-Connection-Pool: creating connection: 4

这里是“修复”：

var connectionConfig = {
    userName: 'xxx',
    password: 'yyy',
    database: 'zzz',
    server: '127.0.0.1',
    port: 1443,
    debug: true,
    driver: 'tedious',
    options: {
        port: 1443,
        encrypt: false,
        database: 'www',
        useColumnNames: false,
        debug: {
            packet: true,
            data: true,
            payload: true,
            token: true,
            log: true
        }
    }
};

注意将port 设置移动到选项中并删除instanceName: 'SQLEXPRESS' 选项设置。
