Backbone Fetch Request 是 OPTIONS 方法

I have a Backbone Collection object with the following URL "http://localhost:8080/api/menu/1/featured". I am trying to perform a fetch operation to retrieve the collection from the url and parse it. However, on the server side, the method type that I see for this request is OPTIONS. The server is only suppose to support GET method. I am not sure how Backbone is figuring out what method type to use, and why it changes to OPTIONS method type randomly sometimes. I am using a Node.js server to process the request. This code below is pretty much what I did.

var FeaturedCollection = Backbone.Collection.extend({
    model:FeaturedContent,
    url:function () { return url_featured; },
    parse:function (response) {
        console.log(response);
        return response;
    }
});

var featuredCollection = new FeaturedCollection();
featuredCollection.fetch();

请帮忙，谢谢！

已经有一段时间了，但我记得以前遇到过这个.这可能是两件事: 默认情况下，Backbone 尝试对后端执行 RESTful API 调用，这意味着 GET、POST、PUT 和 DELETE.
