如何指定URL和头骨干在我的模型中使用的方法CRUD？

问题描述

我需要作出格外API密钥的需要服务器的请求，我需要使用CRUD方法涂更新我的模型，并尽快...

i need to make request on server that needs of particulary api key and i need to use the crud method tu update my model and as soon as...

例如我在阿贾克斯这code从服务器获取元素：

For example i have this code in ajax to get element from server:

 function getapi() {

$.ajax({
    url: 'https://api.parse.com/1/classes/autolavaggi/QSfl*****',
    type: 'GET',
    dataType: 'json',

    success: function(obj) { 

        alert("nome autolavaggio "+obj.nome);

    },
    error: function() {
        alert('Errore');


    },
    beforeSend: setHeader
});
}  

    //GET GET  GET  GET  GET GET  GET  GET  Header Header Header Header
    function setHeader(xhr) {
xhr.setRequestHeader('X-Parse-Application-Id', 'aqLJlmE2rRXBOy***************');
xhr.setRequestHeader('X-Parse-REST-API-Key', 'gvT2Isd5vAvjgq*****************');
}

我怎样才能做到分配这个特殊的Ajax调用CRUD方法保存，提取或另一种??

How can i do to assign this particular ajax call to crud method save,fetch or another??

推荐答案

每个的CRUD方法接受一个选项哈希值，将被转发到Ajax调用。在集合的情况下获取：

Each of the crud methods accept an options hash that will get forwarded to the ajax call. In the case of a collection fetch:

var Model = Backbone.Model.extend({});
var Collection = Backbone.Collection.extend({
  model: Model,
  url: 'https://api.parse.com/1/classes/autolavaggi/QSfl*****'
});

var setHeader = function (xhr) {
  xhr.setRequestHeader('X-Parse-Application-Id', 'aqLJlmE2rRXBOy***************');
  xhr.setRequestHeader('X-Parse-REST-API-Key', 'gvT2Isd5vAvjgq*****************');
}

var collection = new Collection();
collection.fetch({ beforeSend: setHeader });

另外，覆盖的同步：

Alternatively, override sync:

var sync = Backbone.sync;
Backbone.sync = function(method, model, options) {
  options.beforeSend = function (xhr) {
    xhr.setRequestHeader('X-Parse-Application-Id', 'aqLJlmE2rRXBOy***************');
    xhr.setRequestHeader('X-Parse-REST-API-Key', 'gvT2Isd5vAvjgq*****************');
  };

  // Update other options here.

  sync(method, model, options);
};
