Question

I tried to make a resumable upload without much success.

I read the https://developers.google.com/drive/manage-uploads#resumable page but I can’t figure out how to get this “Location” header in the response of the first request.

The API documentation specify that we can make either a POST or a PUT on the first URL, but if I make a PUT, I get a 404, and if I make a POST I get a new file created with no content and no Location header in the response.

Here is my POST query (with a PUT and exactly the same query it returns a 404):

POST https://www.googleapis.com/drive/v2/files?uploadType=resumable
Accept = application/json
Authorization = Bearer xxxxxxxxx
Content-Length = 71
Content-Type = application/json
X-Upload-Content-Length = 10
X-Upload-Content-Type = text/plain

{
    mimeType = "text/plain";
    parents =     (
                {
            id = root;
        }
    );
    title = "test.txt";
}

and the response:

"Cache-Control" = "no-cache, no-store, max-age=0, must-revalidate";
"Content-Type" = "application/json; charset=UTF-8";
Date = "Wed, 29 Aug 2012 09:53:15 GMT";
Etag = "\"UlXjrWs5BKksMni8RDMKhlFkHGQ/MTM0NjIzMzk5NTA2MQ\"";
Expires = "Fri, 01 Jan 1990 00:00:00 GMT";

"Transfer-Encoding" = Identity;
"X-Content-Type-Options" = nosniff;
"X-Frame-Options" = SAMEORIGIN;

The HTTP Request specified in the Files Insert documentation page ( https://developers.google.com/drive/v2/reference/files/insert) is the following :

POST https://www.googleapis.com/drive/v2/files

But it’s wrong. The correct method is specified on the Upload Files page (https://developers.google.com/drive/manage-uploads#resumable) and is :

POST https://www.googleapis.com/upload/drive/v2/files?uploadType=resumable

Note the upload in the URL. Tricky!
