ajaxSetup (beforeSend not working

jqueryajaxheader

提问by abc123

after login to remote aPI server, and getting an access_token, I try to set the authorization header for all subsequent ajax calls :

登录到远程 API 服务器并获得 access_token 后,我尝试为所有后续 ajax 调用设置授权标头:

      .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);
             }
         });

on console I can see :

在控制台上我可以看到:

GOT AUTHORIZATION login.js:34
Bearer 6b7578772fbb4178793100651f2234de840237fe

but none of subsequent ajax calls get the correct header set :

但随后的 ajax 调用都没有获得正确的标头集:

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

cannot succeed as no access_token is found in the header ( server console ..)

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

I tried to modify the header inside the ajax call wo any success

我试图修改 ajax 调用里面的标题 wo 是否成功

更新答案

As of jQuery 1.5 .ajaxsupports headersproperty

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 ) );
    }
});

Notes: the authorizationvariable should be set somewhere before this call

注意:该authorization变量应在此调用之前的某处设置



Old Answer

旧答案

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

For the ajaxSetupto work you need to call it in the document.ready.

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

I know this is an old question, but I came here from Google and thought other people searching the same thing should have a working solution. I have tried the suggested answer but it does not work for me.

我知道这是一个老问题,但我从 Google 来到这里,并认为其他搜索相同内容的人应该有一个可行的解决方案。我已经尝试了建议的答案,但它对我不起作用。

A solution which solved my problem is to set header directly in xhrobject inside of $.ajaxSend:

解决我的问题的解决方案是直接在以下xhr对象中设置标头$.ajaxSend

$(document).ajaxSend(function(ev, xhr, settings) {
  xhr.setRequestHeader('Authorization', `Bearer ${localStorage.getItem(AUTH_TOKEN)}`);
  xhr.setRequestHeader('X-Marketplace', localStorage.getItem('marketplace'));
});

You should call it in the document.readyfor the ajaxSendto work.

你应该把它在document.readyajaxSend工作。
