Question

我正在尝试从节点服务器获取一些数据，这可以正常工作，但是当我尝试通过Backbone fetch（或同步）获取数据时，请求失败。我注意到，由于某种原因，实际请求是错误的：'GET http://localhost:3000/socket.io/1/'应该是'GET http://localhost:3000/cars'，因为'/ cars'是Backbone使用的URL字段的值这些行动的惯例。这些是相关模块：

var Backbone = require("backbone");
var Car = require('models/car');
var Cars = Backbone.Collection.extend ({
    model: Car,
url: '/cars',
// Unselect all Car Cards
resetSelected: function() {
    for (var i=1; i<=this.length; ++i) {
        var carcard=this.get(i);
        carcard.set({"selected": false});
        console.log(carcard.attributes.name + ' unselected');
    }
},
// Select a specific model from the collection
selectByID: function(id) {
    this.resetSelected();
    var carcard = this.get(id);
    carcard.set({"selected": true});
    console.log(carcard.attributes.name + " selected");
    return carcard.attributes.id;
}
});
module.exports = Cars;

一个模特：

var Backbone = require("backbone");
var Car = Backbone.Model.extend({
defaults: {
    year: 2011,
    brand: "Brand",
    model: "Model",
    name: "Car Name",
    pictureFle: "img/car.jpg",
    kmTraveled: 0,
    litresSpent: 0,
    selected: false
},
});
module.exports = Car;

我试图像这样填充这个集合：

var cars = new Cars();
cars.fetch();

但是，正如我解释的那样，失败了。任何想法可能是什么问题？

主干提取（或同步）不会查找正确的URL
