我正在使用jQuery Fileupload上传文件。它没有发送我设置到服务器的标题。为什么授权标题仅在IE中缺失但在chrome中传递?
以下是代码:
upload_photo: function(){
var url = '/api/v1/upload';
$('#photoupload').fileupload({
url: url,
dataType: 'json',
paramName: 'uploadFile',
beforeSend: function ( xhr ) {
setHeader(xhr);
$("#check_progress").html('true');
},
done: function (e, responseJSON) {
var id = responseJSON.result.id;
url = responseJSON.result.url;
var photo_ids = $("#photo_ids");
var val = photo_ids.val();
photo_ids.val(val + id.toString() + ",");
$(".photothumb-wapper").append('<div class=\"photothumb\" id="post_photo_'+id+'"><div><img src=\"'+url+'\" /></div><img class=\"thumb-delete photo_delete\" id=\"'+id+'\" title=\"Remove\" src=\"/assets/delete-red.png\"></div>');
$("#check_progress").html("");
},
start: function (e, data) {
$(".photothumb-wapper").append('<div class="photothumb photoprogress" style="border:none"><img src="/assets/ajax-loader.gif" /></div>');
},
always: function (e, data) {
$(".photoprogress").remove();
}
});
}
var setHeader = function (xhr) {
xhr.setRequestHeader('Authorization', 'Bearer fdf49c4f1cfgc176eb952f18eeefaec3e7');
};
在IE中传递标题:
Request : POST /api/v1/upload HTTP/1.1
Accept : text/html, application/xhtml+xml, \*/\*
Referer : url
Accept-Language : en-US
User-Agent :Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; Trident/5.0)
Content-Type :multipart/form-data; boundary=---------------------------7de2dfe037204f6
Accept-Encoding :gzip, deflate
Host :url
Content-Length :776595
DNT :1

Cache-Control :no-cache
Cookie :sitecookies
在Chrome中传递了标题:
ResponseHeaders

Connection: Keep-Alive
content-length:225
content-type:application/json; charset=utf-8

RequestHeaders

Authorization: Bearer fdf49c4f1cfgc176eb952f18eeefaec3e7
X-Requested-With: XMLHttpRequest
为什么IE中缺少授权标头?

This回答了我的问题,
只有支持XHR文件上传的浏览器才支持设置自定义标题。

作为我们亲爱的IE之类的旧浏览器中的解决方法,您可以在用户进行身份验证时使用身份验证令牌设置cookie,然后在服务器中获取它并以与验证标头相同的方式验证它。我知道这不是最优雅的解决方案,但它确实有效。
