FTP_TLS error "extra keyword arguments given" on Pico W (RP2) port

[JMFUS]

Hello
Here is my code :

import network
from ftplibtls import FTP_TLS

status_reseau = connect_wifi_local("NETWORK", "123456789")[1]

if status_reseau == 3:

    try:
        
        ftp_tls = FTP_TLS()
        print("1")
        ftp_tls.connect(adresse_serveur, port)
        print("2")
        ftp_tls.login(utilisateur_1, mot_de_passe_1)
        print("3")
        ftp_tls.prot_p()
        print("4")
        files = ftp_tls.nlst()
        print(files)
        
    except Exception as e:
        erreur = str(e)
        print("Erreur FTPS : " + str(e))

But I have the following error on the login line :

Erreur FTPS : extra keyword arguments given

Someone can help me?

Thx

Please remove the wrapping of the code in a try/except block and run it again. That way you will get a full exception traceback, which shows where the error happens exactly.

Thx for your answer
Now I have :
Traceback (most recent call last):
File "", line 142, in
File "ftplibtls.py", line 63, in login
File "ftplibtls.py", line 80, in auth
TypeError: extra keyword arguments given

Which Micropython port are you using? Unix, stm32, esp2866, esp32, etc. ?

[JMFUS]

I'm working on a Raspberry Pi Pico W with Micropython 1.20
My FTP server is a Filezilla 0.9.60 server with this options

[SpotlightKid]

The Pico W port is unfortunately not supported yet, since I don't have a Pico W board to test against.

The API of the socket and ssl modules is slightly different on each MicroPython port and it seems that the ssl.wrap_socket function on the Pico W port does not support all the keyword arguments used by the current ftplibtls code.

You can try whether the variant for the ESP boards in the esp/ftplib.py and esp/ftplibtls.py files works on the Pico W as well, but they may very well do not.

Alternatively, you can try changing lines 77-80 of ftplibtls.py to:

        wrapped = ssl.wrap_socket(sock,
                                  keyfile=self.keyfile,
                                  certfile=self.certfile)

i.e. remove the cert_reqs keyword argument.

---

P.S.: If someone would sponsor me by sending me a Pico W board, I could "officially" support the Pico W port 😀

[JMFUS]

I changed the lines 77-80 of the ftplibtls.py but the result is the same :(

[SpotlightKid]

Try removing the keyfile and certfile arguments as well.

Note: of course this means that no certificate validation will take place, which partly defeats the purpose of using TLS. So use at your own risk!

[JMFUS]

I allready tried to remove all argumentsand it's working
I understand there's a risk

[JMFUS]

I can connect to my FTPS server but I can't list the files of my directory

[SpotlightKid]

This seems to be another incompatibility of the socket or ssl module on the RP2.

I can only repeat: the RP2 is not supported and unless I can get my hands on a Pico W board, I can do nothing about it.

I suggest looking for help on the MicroPython forum until then:

Thx

[SpotlightKid]

I finally got my hands on a Raspberry Pi Pico W board and I believe this issue is now fixed and FTP over TLS also works on the rp2 port.

@JMFUS I would appreciate if you could test this and confirm that it works for you.

Please see the README for usage notes.

[JMFUS]

Hi
Thx for the work
I'm actuelly devopping other thing but when it will finished, I'll test this version and comme back to you

[SpotlightKid]

Assuming this to be fixed by 6c19a84.

Feel free to re-open, if the error persists with the latest version of the code in this repo.

If you have any other problems using this on the PR2 (or any other) port, please open a new ticket.
