推荐答案

Backbone 中的模型使用 fetch、save 和 方法检索、更新和销毁数据代码>破坏.这些方法将实际请求部分委托给 Backbone.sync.在幕后，Backbone.sync 所做的就是使用 jQuery 创建一个 ajax 请求.为了合并您的基本 HTTP 身份验证，您有几个选择.

Models in Backbone retrieve, update, and destroy data using the methods fetch, save, and destroy. These methods delegate the actual request portion to Backbone.sync. Under the hood, all Backbone.sync is doing is creating an ajax request using jQuery. In order to incorporate your Basic HTTP authentication you have a couple of options.

fetch、save 和 destroy 都接受一个附加参数 [options].这些 [options] 只是一个包含在 jQuery ajax 调用中的 jQuery 请求选项字典.这意味着您可以轻松定义一个简单的方法来附加身份验证:

fetch, save, and destroy all accept an additional parameter [options]. These [options] are simply a dictionary of jQuery request options that get included into jQuery ajax call that is made. This means you can easily define a simple method which appends the authentication:

sendAuthentication = function (xhr) {
  var user = "myusername";// your actual username
  var pass = "mypassword";// your actual password
  var token = user.concat(":", pass);
  xhr.setRequestHeader('Authorization', ("Basic ".concat(btoa(token))));
}

并将其包含在您进行的每个 fetch、save 和 destroy 调用中.像这样:

And include it in each fetch, save, and destroy call you make. Like so:

 fetch({
  beforeSend: sendAuthentication 
 });

这会造成相当多的重复.另一种选择是覆盖 Backbone.sync 方法，复制原始代码并将 beforeSend 选项包含到每个 jQuery ajax 请求中.

This can create quite a bit of repetition. Another option could be to override the Backbone.sync method, copy the original code and just include the beforeSend option into each jQuery ajax request that is made.
