ajaxSetup(beforeSend不工作

Question

登录到远程aPI服务器并获取access_token后,我尝试为所有后续的ajax调用设置授权头:

      .done(function (result) {
         console.log("GOT AUTHORIZATION");
         amplify.store( "tokens", { access_token: result.access_token, refresh_token: result.refresh_token, token_type: result.token_type, expires_in: result.expires_in });
         var authorization = 'Bearer ' + amplify.store( "tokens" ).access_token;
         console.log(authorization);

         $.ajaxSetup({
             beforeSend: function(xhr) {
                 xhr.setRequestHeader('Authorization', authorization);
             }
         });

在控制台上,我可以看到:

GOT AUTHORIZATION login.js:34
Bearer 6b7578772fbb4178793100651f2234de840237fe

但后续的ajax调用都没有得到正确的标头集:

https://macmini.local:8000/Categories?_=1381758170726 

无法成功,因为在标头中找不到access_token(服务器控制台..)

{ code: 400,
   error: 'invalid_request',
   error_description: 'The access token was not found',stack: undefined }
saveAccessToken: 6b7578772fbb4178793100651f2234de840237fe, client_id: 1234567890, user_id: 1

我尝试修改ajax调用中的标题,任何成功

更新的答案

从jQuery 1.5开始.ajax支持headers属性

$.ajax({
    url: "http://fiddle.jshell.net/favicon.png",
    headers: {
        'Authorization': authorization
    }
})
.done(function( data ) {
    if ( console && console.log ) {
        console.log( "Sample of data:", data.slice( 0, 100 ) );
    }
});

注意:authorization变量应该在此调用之前的某处设置

老答案

$(function(){
    $.ajaxSetup({
        beforeSend: function(xhr) {
                 xhr.setRequestHeader('Authorization', authorization);
             }
    });
});

对于ajaxSetup工作,您需要在document.ready中调用它.
