poco a poco almenos me voy dando cuenta que es lo que no entiendo
In all scenarios, clients must send an HTTP POST request to the resumable-create-media link of the resources feed. To acquire this link, clients query
https://docs.google.com/feeds/default/private/full. It is recommended that clients not hard-code this link, in case the link changes. In the following sections, this link is referred to as [resumable-create-media link].
<link rel="http://schemas.google.com/g/2005#resumable-create-media" type="application/atom+xml"
href="https://docs.google.com/feeds/upload/create-session/default/private/full"/>
como se supone que debo tratar eso aqui?
POST [resumable-create-media link]
Content-Length: 359
Content-Type: application/atom+xml
X-Upload-Content-Length: 0
a lo máximo que llego es esto
$link='https://docs.google.com/feeds/upload/create-session/default/private/full';
$headers = array(
"Authorization: GoogleLogin auth=" . $_SESSION['auth'],
"GData-Version: 3.0",
"Content-Length: 359",
"Content-Type: application/atom+xml",
"X-Upload-Content-Length: 0",
);
