使用package.json傳遞數據庫URL

Question

我正在使用package.json傳遞URL STRING

"scripts": {
  "start": "set DB_PORT=53345 && set MONGOLAB_URI='mongodb://localhost/ivr' && node server.js" 
}

控制台輸出

console.log(process.env.MONGOLAB_URI)   //  'mongodb://localhost/ivr'
console.log('mongodb://localhost/ivr')  // mongodb://localhost/ivr

錯誤：

Error: Invalid mongodb uri. Must begin with "mongodb://"
      Received: 'mongodb://localhost/ivr'

Answer 1

請嘗試這種方式

"scripts": {
    "start": "set DB_PORT=53345&&set MONGOLAB_URI=mongodb://localhost/ivr&&node server.js"

}

Answer 2

刪除mongodb uri周圍的單引號：

set MONGOLAB_URI=mongodb://localhost/ivr

順便說一句，你可以做：

"start": "DB_PORT=53345 MONGOLAB_URI=mongodb://localhost/ivr node server.js"
