问题描述

我是backbone.js 的新手.我正在尝试使用我的服务发布数据，它返回我的数据.我的服务是:http://192.168.1.3:8080/app/search/candidate 输入为

I am new to backbone.js.I am trying to POST data with my service and it returns me data. My service is: http://192.168.1.3:8080/app/search/candidate It takes Input as

{
  "skills":["c","java"]
 }

它会向我返回用户列表.所以我在主干中创建了集合并尝试我的代码是

And it returns list of users to me. so I created collection in backbone and tried My code is

var UserModel = Backbone.Model.extend({
});

var EntityList = Backbone.Collection.extend({       
        model: UserModel,
        url: `'http://192.168.1.3:8080/app/search/candidate'`

        });



 var View = Backbone.View.extend({

    el : '#mydiv',
    template : _.template($("#details").html()),
    initialize : function() {   
          var self = this;     
          this.coll = new EntityList();
         // this.coll.bind("reset", _.bind(this.render, this));
         this.coll.fetch({
         data:JSON.stringify({'skills':['c','java']}),

         type: 'POST' ,   

         success: function(){
                 //console.log(this.coll.toJSON());
                 self.render();
                 }}); 
        } ,          

    render : function() {
      // the persons will be "visible" in your template
      this.$el.html(this.template({ persons: this.coll.toJSON() }));
      return this;
    }

            });
var view = new View();

但它给了我状态代码:HTTP/1.1 415 Unsupported Media Type我在哪里失踪?来自 chrom 调试器的请求标头是

But it gives me Status Code: HTTP/1.1 415 Unsupported Media Type Where I am missing? Header for request from chrom debugger is

推荐答案

这段代码有效，在控制台看到的请求头是这样的 jsfiddle :

This code worked, see the request headers in the console is this jsfiddle :

    this.coll.fetch({

        beforeSend: function (xhr) {
            xhr.setRequestHeader('Content-Type', 'application/json');
        },

        data: JSON.stringify({'skills':['c','java']}),

        type: 'POST',

        success: function () {
            //console.log(this.coll.toJSON());
            self.render();
        }
    });
