404錯誤嘗試加載平均網絡應用程序

所以我試圖建立一個基本的Todo列表/ CRUD應用程序使用MEAN堆棧（Angular，MongoDB，Nodejs，Express），當我切換時遇到麻煩路徑和模型，並嘗試在我的命令提示符下通過節點服務器加載應用程序。當我移動任何東西時，下面的錯誤是通過命令提示符錯誤得到的。只是一個參考，我是一個總NOOB。404錯誤嘗試加載平均網絡應用程序

（假設您從客戶端發送正確的_id），您必須將_id重建爲BSON對象。不知道你用什麼數據庫驅動程序，但在mongoskin它是這樣說：

var mongo = require('mongoskin'); 
var BSON = mongo.BSONPure; 

... 

var proper_id = BSON.ObjectID(req.params.todo_id)

在mangoose嘗試以下操作：

var todo = Todo.find({_id : req.params.todo_id}); 
todo.remove(callback(err, todo)); // callback is optional

使用貓鼬！我會試試這個。 – user2993058

它必須支持BSON對象 –
