Content-Transfer-Encoding in file upload request [英] Content-Transfer-Encoding in file uploading request

问题描述

我正在尝试使用XMLHTTPRequest上传文件，并发送此标题：

I'm trying to upload file, using XMLHTTPRequest, and sending this headers:

Content-Type:multipart/form-data, boundary=xxxxxxxxx

--xxxxxxxxx
Content-Disposition: form-data; name='uploadfile'; filename='123_logo.jpg'
Content-Transfer-Encoding: base64
Content-Type: image/jpeg
/*base64data*/

但是在服务器端PHP忽略标题Content-Transfer-Encoding：base64
并将base64未解码的数据直接写入文件！

But on server side PHP ignore header "Content-Transfer-Encoding: base64" and write base64 undecoded data directly into the file!

有没有办法解决它？

ps使用base64发送数据非常重要

p.s. it is very important to send data using base64

推荐答案

实际上HTTP
中没有内容传输编码见

In fact there is no Content-transfer-encoding in HTTP see

http：//www.ietf .org / rfc / rfc2616.txt

19.4.5无内容转移编码

19.4.5 No Content-Transfer-Encoding

HTTP不使用RFC 2045的
Content-Transfer-Encoding（CTE）字段
。

HTTP does not use the Content-Transfer-Encoding (CTE) field of RFC 2045.

但您可以使用base64_decode，如 http：// php .net / manual / en / function.base64-decode.php

but you can use base64_decode as in http://php.net/manual/en/function.base64-decode.php
