Question

我几天来一直在反对这一点，我仍然不确定是什么问题。一加载localhost，我就会收到无限的项目列表。这些物品通常是空的，不含任何物品。当我尝试删除它们时，我收到404错误，上面写着“api / todos / undefined”。

以下是代码。对不起，我很抱歉。我根本不知道错误在哪里。也许这是在命名？肯定存在路由问题。

var mongoose = require('mongoose');

mongoose.connect('mongodb://localhost/');

var Todo = mongoose.model('todos', {
    text : String
});

module.exports.Todo = Todo;

控制器

var baselTodo = angular.module（'baselTodo'，[]）;

function mainController($scope, $http) {
    $scope.formData = {text: ''};

    // when landing on the page, get all todos and show them
    $http.get('/api/todos')
        .success(function(data) {
            $scope.todos = data;
        })
        .error(function(data) {
            console.log('Error: ' + data);
        });


    // when submitting the add form, send the text to the node API
    $scope.createTodo = function() {
        $http.post('/api/todos', $scope.formData)
            .success(function(data) {
                $scope.todos = data;
            })
            .error(function(data) {
                console.log('Error: ' + data);
            });
        $http.get('/api/todos').success(function(data) {
            $scope.todos = data;
        })
    };

    // delete a todo after checking it
    $scope.deleteTodo = function(id) {
        $http.delete('/api/todos/' + id)
            .success(function(data) {
                $scope.todos = data;
            })
            .error(function(data) {
                console.log('Error: ' + data);
            });
    };

    {
    $scope.updateTodo = function(id) {
       $scope.newItem = prompt("Please enter your new item: ", "");
        $http.put('/api/todos/' + id, {text: $scope.newItem}).success(function(data) {
                $scope.todos = data;
            });

            $http.get('/api/todos').success(function(data) {
                $scope.todos = data;
            });
    }};




};

服务器

// ================== SERVER.JS ========================

    // set up ------------------------------------------
    var api = require('./routes/api');
    var express = require('express');
    var app = express();    

    // configuration -----------------------------------
    app.configure(function() {
        app.use(express.static(__dirname + '/public'));
        app.use(express.logger('dev'));
        app.use(express.bodyParser());
        app.use(express.methodOverride());
    });

    // listen (start app with node server.js) ----------
    app.listen(3000);
    console.log("App listening on port 3000");

    // routing -----------------------------------------

    // Main Page
    app.get('/', function(req, res) {
        res.sendfile('./public/index.html');
    });

    // API Routing
    app.get('/api/users', api.read);
    app.post('/api/users', api.create);
    app.put('/api/users/:_id', api.update);
    app.delete('/api/users/:_id', api.delete);

Answer 1

您的server.js文件中缺少分号。你想要这个：

app.put('/api/todos/:_id', api.update);

也可以在另一个分号上添加分号。

MEAN Stack CRUD todolist提供无限列表，不会删除
