How could I login by ftp from Emacs with elisp?

Question

I have defined the following function with Emacs, I defined the "username" for a website and the associated "password". But, how could I make this function show a dired view of the ftp like it does when you login with the regular method ( /username@ftp.site.com:/ )

(defun myftp_login()
  "Login to a ftp"
  ( ange-ftp-set-user "ftp.site.com" "username" )
  ( ange-ftp-set-passwd "ftp.site.com" "username" "password" )
  ;; command to open dired view to a folder in ftp.site.com
 )

I already searched for similar questions but I couldn't find one that solves my problem, thank you.

solution: As Tobias and Michael Albinus pointed out, the code should look like this and the passwords should be stored in ~/.netrc for safer storage:

(defun ftplogin_site()
  "Login to the ftp.site.com"
  (interactive)
  ( ange-ftp-set-user "ftp.site.com" "username" )
  ( find-file "/username@ftp.site.com:/folder/folder/")
 )

Thank you everyone for your help.

Answer 1

You don't need to touch ange-ftp variables. Open a file like Cx Cf /ftp:username@ftp.site.com:/

Answer 2

You can use (find-file "/username@ftp.site.com:/") .

The best first place to dig is often the key-binding. The key combination Ch k Cx Cf reveals find-file .
