Use curl to download from a Url

Question

I am trying to download a file from a url using curl:

$ curl -3 -v "https://atl1mmsget.msg.eng.t-mobile.com/mms/wapenc?location=XXXXXXXXXXX_14zbwk&rid=027"

Where the X is a digit in the phone number of the device I am testing on.

but I am running into an error:

What does the 501 not implemented error mean? How can I get around this?

Answer 1

The error code is provided by the server side, not by curl. It is an HTTP error code and the description for that can be found on wikipedia:

501 Not Implemented
The server either does not recognize the request method, or it lacks the 
ability to fulfill the request. Usually this implies future availability 
(e.g., a new feature of a web-service API).

You should try to get access to the functionality with a real browser, to make sure this works (the url you provided doesn't work in my browser). Once that works you can try deleting any cookies to see if accessing the page depends on any of that. You might have to go for something like using selenium if you want to automate accessing that page.
