从Angular.js $ http请求中删除标头

I want to delete some $http request header fields from one specific request (it means not on the $httpProvider level). These fields are:

我想从一个特定的请求中删除一些$ http请求头字段（这意味着不在$ httpProvider级别）。这些字段是：

• Cache-Control
• 缓存控制
• If-Modified-Since
• 如果-Modified-Since的
• Referer

• X-Requested-With
• X-要求，随着

How to do this in a single request? I tried to use transformRequest parameter, but didn't find enough information to make it work. Such a [CoffeeScript] code:

如何在一个请求中执行此操作？我试图使用transformRequest参数，但没有找到足够的信息使其工作。这样的[CoffeeScript]代码：

$scope.logout = ->
  $http({
    method: 'GET'
    url: '/api/logout'
    headers: { 'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8' }
    transformRequest: (data, headersGetter) ->
      console.log data
      console.log headersGetter
      data
  }).success ->
    $location.path('editor')

shows that data is undefined, headersGetter is function (c){a||(a=Nb(b));return c?a[y(c)]||null:a} (which says to me absolutely nothing), and I didn't understand what to return from the transformRequest function.

表明数据是未定义的，headersGetter是函数（c）{a ||（a = Nb（b））;返回c？a [y（c）] || null：a}（它绝对没有对我说），我不明白从transformRequest函数返回什么。

1. If you use the unminified version of Angular, you'll get nicer backtraces when an exception happens, and you'll have an easier time introspecting the angular code. I personally recommend it while developing. Here's what headersGetter actually looks like:

   如果你使用Angular的非限制版本，当异常发生时你会得到更好的回溯，你可以更容易地反省角度代码。我个人在开发时推荐它。这是headersGetter实际上的样子：

   function (name) {
       if (!headersObj) headersObj =  parseHeaders(headers);
   
       if (name) {
         return headersObj[lowercase(name)] || null;
       }
   
       return headersObj;
     } 
   

   The data argument to your transformer will be undefined unless you’re POSTing some data.

   除非您正在发布一些数据，否则您的变换器的数据参数将是未定义的。

2. The headersGetter function takes an optional argument name, if you want to get a single header, but you omit the argument to set a header:

   headersGetter函数采用可选的参数名称，如果您想获得单个标头，但省略了设置标头的参数：

   headersGetter()['Cache-Control'] = 'no-cache';
   headersGetter()['X-Requested-With'] = '';
   

   The return value from your transformer should be the value of data you want to use.

   变换器的返回值应该是您要使用的数据的值。

3. You can’t change the Referer header from XHR.

   您无法从XHR更改Referer标头。
