Question

我怎样才能将apiKey = 12341234附加到每个ajax请求上进行获取，创建，保存等等...... MongoLabs api需要这个，而且我一直在努力让它完全运行。

我目前正在使用骨干教程截屏，作者正在使用php框架为骨干应用程序创建api。我以为我会通过使用MongoLabs免费休息api来变得聪明......然后我烧了2天阅读文档并尝试使其工作。

我最接近的是在调用fetch时传递参数（不适用于create）：Fetch Backbone collection with search parameters

{ data: $.param({'apiKey':'50b28f80e4b0995a3f4312a0'}) }

jsfiddle上的代码： http://jsfiddle.net/py4Pv/

# Encapsulate classes
window.App =
  apiKey: { data: $.param({'apiKey':'50b28f80e4b0995a3f4312a0'}) }
  Models: {}
  Views: {}
  Collections: {}



# The model for a single task
class App.Models.Task extends Backbone.Model
  #override backbones 'id' attr to match mongo's '_id' attr
  idAttribute: "_id"
  defaults:
    title: "None provided"
    completed: 0


# The model for a collection of tasks
class App.Collections.Tasks extends Backbone.Collection
  model: App.Models.Task
  url: 'https://api.mongolab.com/api/1/databases/bbone_rest/collections/tasks/'





##################### Views, prob not important ########################  


# View for a list of tasks
class App.Views.Tasks extends Backbone.View
  tagName: 'ul'

  initialize : () ->
    @collection.on 'add', @addOne

  render: ->
    # Cycle through each task in collection and call @addOne
    @collection.each @addOne
    return this

  addOne: (task) =>
    task = new App.Views.Task({ model: task })
    @$el.append( task.render().el )


# View for a single task unit
class App.Views.Task extends Backbone.View
  tagName: 'li'
  render: ->
    @$el.html( this.model.get('title'))
    return this

*编辑* 添加：$ .ajaxSetup（{data：{key：“value”}在task.destroy（）之后的标题信息

Answer 1

You can specify a function for the url property of the model/collection - 这样你每次都应该能够在查询字符串中附加api。就是这样的（对不起，我不确定Mootools的语法）：

url: () => 
   return 'https://api.mongolab.com/api/1/databases/bbone_rest/collections/tasks/' + this._id + '?api=' + App.apiKey

Answer 2

你试过了吗？

$.ajaxSetup({
  data: {
    key: "value"
  }

这将为每个ajax请求添加密钥参数。在ajaxSetup中声明的数据是累积的。

Answer 3

处理此问题的最佳方法是 ajaxPrefilter

var api_key = '465456132456'
$.ajaxPrefilter( function( options, originalOptions, jqXHR ) {
  options.url = 'YOUR_URL' + options.url + '?key=' + api_key;
});

在Backbone中将api键附加到url时遇到问题
