SQL 服務器的 TypeORM 連接問題

Question

我在本地機器上運行 SQL 服務器實例，當我嘗試從 TypeORM 連接數據庫時，它拋出以下錯誤：

originalError: ConnectionError: 無法連接到 localhost:1433 - 無法連接（序列）

這是我的ormconfig.ts文件的樣子：

{
   "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"
   }
}

這是我的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"
   }
}

當我嘗試運行它時會拋出 ESOCKET 錯誤，

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'

我還附上了 SSMS 配置 window 截圖，

請幫我解決問題。

提前致謝。

Answer 1

Verifique o nome da instancia do seu SQL 服務器，示例：LOCALHOST\MSSQLSERVER。

官方文檔做 TypeORM

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

options.instanceName - 要連接的實例名稱。 數據庫服務器上必須運行SQL服務器瀏覽器服務，並且數據庫服務器上的UDP端口1434必須可達。 與端口互斥。 （無默認值）。

沒有 seu arquivo ormconfig.json você coloca：

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

Answer 2

你應該輸入端口：''，在''中的端口號和你要連接的SQL服務器的用戶名的主機下面''用戶名：''，以及SQL服務器用戶登錄的密碼密碼：''，
