I'm on Mac OSX trying to use telnet to get a file off of google drive. I found that the following link template causes an automatic download of a file off of google drive:

http://drive.google.com/uc?id=documentId&export=download

where documentId is the id of the document (a combination of numbers and letters). So I go to the terminal, type telnet drive.google.com 80 and get connected to the server. Then I type GET /uc?id=documentId&export=download HTTP/1.1, press enter, type Host: drive.google.com, then press enter twice.

I'm pretty sure I followed the steps correctly, but for some reason, I always get a status code of 302 Moved Temporarily. Did I enter the URL wrong, are there some characters that need to be escaped? Any suggestions would be helpful.

302 Moved Temporarily is not an error of any kind. It's the HTTP server telling you that the URL is okay but the actual content is at a different location; for example, it might be redirecting you to one of Google's storage servers, or asking to try again over HTTPS.

Look for a Location: header in the response and issue a second HTTP request for it (after connecting to the apropriate server if needed).

As a better alternative, try curl -L -o <filename> <url>.
(Add -v if you want to see the HTTP requests in action.)

is curl an actual command? Because I'm just using telnet to test out the HTTP request which later I'm going to use in a C++ program to download the file off the internet. –  rcplusplus Jul 24 '12 at 3:39
    
And also, the "new location" link it gives me is this: /uc?id=documentId&amp;export=download, which is the exact same thing [!] as the provided link save for the ampersand being replaced by &amp –  rcplusplus Jul 24 '12 at 3:43
    
@rcplusplus: If it has something different, then it's not exactly the same thing, is it? –  grawity Jul 24 '12 at 11:20
    
@rcplusplus: And yes, curl is an actual command, but it also comes with a libcurl library for C which is very convenient for downloading files over HTTP, among other things. –  grawity Jul 24 '12 at 11:21

Need to use HTTPS, do you have some kind of SSL-equipped telnet?

Tried it your way with openssl, and it worked! Well, it gave me HTML saying "Moved Temporarily" and then had a <a></a> element directing me to the file. All I do is click it and then the file downloads. And that URL is the Location: parameter in the response header –  rcplusplus Jul 24 '12 at 4:53
