404错误尝试加载平均网络应用程序

所以我试图建立一个基本的Todo列表/ CRUD应用程序使用MEAN堆栈（Angular，MongoDB，Nodejs，Express），当我切换时遇到麻烦路径和模型，并尝试在我的命令提示符下通过节点服务器加载应用程序。当我移动任何东西时，下面的错误是通过命令提示符错误得到的。只是一个参考，我是一个总NOOB。404错误尝试加载平均网络应用程序

（假设您从客户端发送正确的_id），您必须将_id重建为BSON对象。不知道你用什么数据库驱动程序，但在mongoskin它是这样说：

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

... 

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

在mangoose尝试以下操作：

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

使用猫鼬！我会试试这个。 – user2993058

它必须支持BSON对象 –
