上傳文件以替換數據庫中的表的問題

我想上載一個包含多個對象的數組的文件，並用它來替換我的貓鼬數據庫中的表。這是文件的樣子：上傳文件以替換數據庫中的表的問題

var newRooms = [ 
    {name: "yogaStudio", 
    title: "Yoga Studio", 
    description: "This is where StarFleet officers go to get bendy", 
    roomExits: ['kitchen', 'foyer'],} 
    , 

    {name: "kitchen", 
    title: "Kitchen", 
    description: "You must be starving, please come in and make yourself a sandwich", 
    roomExits: ['yogaStudio', 'drawingroom'],} 
    , 

    {name: "foyer", 
    title: "Foyer", 
    description: "This is the entrance hallway", 
    roomExits: ['yogaStudio', 'kitchen'],}, 

    {name: "drawingroom", 
    title: "Drawing Room", 
    description: "Please grab a drink and take a seat, it's stressful navigating around this place", 
    roomExits: ['kitchen', 'foyer'],} 
    , 
];

這是我使用的上傳和更換功能：

var restore = function(req, res) { 
    fs.readFile(req.files.roomFile.path, 'utf8', function (err, data) { 
     if (err) { 
      res.send("File upload error."); 
     } else { 
      overwriteDB(JSON.parse(data), res); 
     } 
    }); 
} 

var overwriteDB = function(newDB, res) { 
    if (!Array.isArray(newDB)) { 
     res.send("Error: Data structure isn't an array."); 
     return; 
    }  
    // Should validate newDB further before deleting old documents. 
    Room.remove({}, function(err) { 
     if (err) { 
      res.send("Error: Couldn't delete all existing documents" + 
      "on restore."); 
      return; 
     } else { 
      console.log("All documents removed before restore."); 
     } 

     newDB.forEach(function(theRoomtoImport) { 
     var theRoom = new Room(theRoomtoImport); 
      theRoom.save(function(err, theRoom) { 
       if (err) { 
        console.log("Failure restoring " + theRoom.name); 
       } else { 
        console.log("Success restoring " + theRoom.name); 
       } 
      }); 
     }); 
     res.send("Restore in progress!"); 
    }); 
}

但我發現了這個錯誤

[email protected]:~/comp2406/adventure-ajax-demo$ node app.js 
Express server listening on port 3000 

undefined:1 
var newRooms = [ 
^ 
SyntaxError: Unexpected token v 
    at Object.parse (native) 
    at /home/sarah/comp2406/adventure-ajax-demo/routes/index.js:75:23 
    at fs.js:252:14 
    at Object.oncomplete (fs.js:93:15)

任何人都可以幫我解決這個問題？

第一個文件是JavaScript，而不是JSON。

如果它的意圖是JSON，只是這樣做：

[ 
    {name: "yogaStudio", 
    title: "Yoga Studio", 
    description: "This is where StarFleet officers go to get bendy", 
    roomExits: ['kitchen', 'foyer'],} 
    , 
    ...

謝謝！這是棘手的一切保持直線我是否像這樣結束];要不就 ]？ – Sarah

只是]你可以使用基於Web的json驗證器來檢查你的工作 – gmcerveny

你需要擺脫

var newRooms =

JSON.parse無法解析此爲有效的JSON字符串。
