SQL 服务器的 TypeORM 连接问题

Question

我在本地机器上运行 SQL 服务器实例，当我尝试从 TypeORM 连接数据库时，它抛出以下错误：

originalError: ConnectionError: 无法连接到 localhost:1433 - 无法连接（序列）

这是我的ormconfig.ts文件的样子：

{
   "type": "mssql",
   "host": "localhost",
   "username": "",
   "password": "",
   "database": "demoDB",
   "synchronize": true,
   "logging": true,
   "entities": [
      "src/entity/**/*.ts"
   ],
   "migrations": [
      "src/migration/**/*.ts"
   ],
   "subscribers": [
      "src/subscriber/**/*.ts"
   ],
   "cli": {
      "entitiesDir": "src/entity",
      "migrationsDir": "src/migration",
      "subscribersDir": "src/subscriber"
   }
}

这是我的package.json文件：

{
   "name": "PLHApi-Dev",
   "version": "0.0.1",
   "description": "Performance Lighthouse Reborn.",
   "devDependencies": {
      "@types/bcryptjs": "^2.4.2",
      "@types/cookie-parser": "^1.4.2",
      "@types/express": "^4.17.9",
      "@types/graphql": "^14.5.0",
      "@types/jsonwebtoken": "^8.5.0",
      "@types/node": "^8.0.29",
      "nodemon": "^2.0.6",
      "ts-node": "3.3.0",
      "typescript": "3.3.3333"
   },
   "dependencies": {
      "apollo-server-express": "^2.19.1",
      "bcryptjs": "^2.4.3",
      "body-parser": "^1.18.1",
      "cookie-parser": "^1.4.5",
      "dotenv": "^8.2.0",
      "express": "^4.15.4",
      "jsonwebtoken": "^8.5.1",
      "mssql": "^4.3.9",
      "reflect-metadata": "^0.1.10",
      "type-graphql": "^1.1.1",
      "typeorm": "0.2.29"
   },
   "scripts": {
      "dev": "nodemon --exec ts-node src/index.ts"
   }
}

当我尝试运行它时会抛出 ESOCKET 错误，

originalError: ConnectionError: Failed to connect to localhost:1433 - Could not connect (sequence)
      at ConnectionError (E:\PLH_API\PLHApi-Dev\node_modules\tedious\lib\errors.js:12:12)

      at processTicksAndRejections (internal/process/task_queues.js:84:21) {
    code: 'ESOCKET'

我还附上了 SSMS 配置 window 截图，

请帮我解决问题。

提前致谢。

Answer 1

Verifique o nome da instancia do seu SQL 服务器，示例：LOCALHOST\MSSQLSERVER。

官方文档做 TypeORM

https://typeorm.io/#/connection-options/mssql-connection-options

options.instanceName - 要连接的实例名称。 数据库服务器上必须运行SQL服务器浏览器服务，并且数据库服务器上的UDP端口1434必须可达。 与端口互斥。 （无默认值）。

没有 seu arquivo ormconfig.json você coloca：

"host": "LOCALHOST",
"options": { 
    "instanceName": "SQLSERVER"
},

Answer 2

你应该输入端口：''，在''中的端口号和你要连接的SQL服务器的用户名的主机下面''用户名：''，以及SQL服务器用户登录的密码密码：''，
