(CURL, PHP) 使用 PUT 请求上传文件，我该如何处理？

Question

this is what i have in process.php

parse_str(file_get_contents("php://input"),$upload_data);
if (isset($upload_data)) {
   print_r($upload_data);
   exit;
}

this is how i query to server using curl.

weldan@prindu:~$ curl -X PUT -H "X-TOKEN: test123" -F filedata=@/home/weldan/Pictures/Cool-Pictures1.jpg  http://host.tld/process.php
Array
(
    [------------------------------22031b6e799c
Content-Disposition:_form-data;_name] => "filedata"; filename="Cool-Pictures1.jpg"
Content-Type: image/jpeg

���
)

so that how i know there is uploaded file there.

current problem is, how do I process this file like $_FILES variable?

open for other way to achieve this too.

Thanks

Answer 1

The $_FILES array being populated on PUT requests. That's because a PUT request will specify the file name in the url and the file content in the body. Nothing more.

You'll have to use php://input as you already suggested.

upload.php

<?php
/* PUT data goes to php://input */
echo file_get_contents("php://input");

Then use the following curl command line:

curl --upload -H "X-TOKEN: test123" a.txt  http://localhost/upload.php

Update after comments : Using the --upload option should fit your needs. In difference to -X PUT together with -F, the data will be send raw and get not multipart/form-data encoded.. One of the hidden treasures of curl ;)

Short answer

The only way in your situation is to parse raw request manually (look at this gist )

Thoughts

• PUT request could be used to upload one file only (not from html upload form, but using custom request). On the server you just get raw file content and writes it into some file.
• Use PUT without files (application/x-www-form-urlencoded) and parse raw request using parse_str(file_get_contents("php://input"), $_PUT);
• Use POST to upload files (multipart/form-data).
