如何在Ajax请求中包含头文件？ [英] How to include header in ajax request?

问题描述

我需要在YouTube api的ajax调用中包含带有刷新令牌的标头。我正尝试发送删除请求，删除我在我的帐户中的电影。这是我的ajax调用点击按钮点击

I need to include a header with a refresh token in an ajax call to the YouTube api. I am trying to send a delete request, to delete a movie I have on my account. This is my ajax call that fire on button click

jQuery.ajax({
        type: 'DELETE',
        // must set api key
        url: 'https://www.googleapis.com/youtube/v3/videos?id='+ thisUniqueID + '&key=904907387177-qe517sq5dmmpebckjbmrhv4gvac9e2d1.apps.googleusercontent.com',
        success: function() {
        alert('your video has been deleted');
        },
        error: function() {
        alert('error processing your requst');
        }
    }); 

我在收到401（未经授权）的erorr时，似乎需要包含我的访问权限令牌。我正在玩Google api游乐场，看着请求和响应，这就是'Request'被发送出去的情况。

I am receiving a 401 (unauthorized) erorr on return and it seems that I need to include my access token in the call. I was playing around with the google api playground looking at the request and response and this is what shows as the 'Request' being sent out

DELETE https://www.googleapis.com/youtube/v3/videos?id=3242343&key={YOUR_API_KEY}

Authorization:  Bearer "access token"
X-JavaScript-User-Agent:  Google APIs Explorer

现在根据该请求，它看起来像是头部是与请求一起被发送，其中持有访问令牌。这一定是我得到401错误的原因。如何将这些头文件包含到我的ajax请求中，以便我的访问令牌与请求一起传递？谢谢

Now from that request it looks like the there are headers that are being sent with the request, which hold the access token. This must be why I am getting a 401 error. How can I include those headers into my ajax request, so that my access token is passed along with the request? Thanks

推荐答案

我可以使用下面的代码传递一个头文件：

I was able to pass along a header using this code below:

    jQuery.ajax({
        type: 'DELETE',
        // must set api key
        url: 'https://www.googleapis.com/youtube/v3/videos?id='+ thisUniqueID +'&key=api_key_here',
beforeSend: function(xhr){xhr.setRequestHeader('Authorization', 'Bearer access_token_here');},
        success: function() {
        alert('your video has been deleted');
        },
        error: function() {
        alert('error processing your request');
        }
    });
