TypeError: a bytes-like object is required, not 'str'

[lolfr]

Hi,

I'm trying to configure this script on a new Raspberry Pi 4.
I already made some changes (i.e. adding () to the print command) but I still get these errors :

Traceback (most recent call last):
  File "/home/pi/configs/gandi-live-dns/src/./gandi-live-dns.py", line 122, in <module>
    main(args.force, args.verbose)
  File "/home/pi/configs/gandi-live-dns/src/./gandi-live-dns.py", line 101, in main
    dynIP = get_dynip(config.ifconfig)
  File "/home/pi/configs/gandi-live-dns/src/./gandi-live-dns.py", line 24, in get_dynip
    print('Checking dynamic IP: ' , r._content.strip('\n'))
TypeError: a bytes-like object is required, not 'str'

I'm not a developper, just an enthusiast and after several hours trying to understand what is the issue, I'm near to giving up.
Did someone as a clue ? Or can help me ?

Best regards,

Laurent

Hi,
Which version of python are you running?
python --version
(to type in a shell)

Hi,
What did you put in config file in ifconfig part?
ifconfig = 'choose_from_above_or_run_your_own'

[lolfr]

I do several tried, with :
• https://ifconfig.co/ip
• http://ifconfig.me/ip
• http://whatismyip.akamai.com/

But I always get the same errors :
Traceback (most recent call last): File "/home/pi/gandi-live-dns/src/./gandi-live-dns.py", line 121, in <module> main(args.force, args.verbose) File "/home/pi/gandi-live-dns/src/./gandi-live-dns.py", line 100, in main dynIP = get_dynip(config.ifconfig) File "/home/pi/gandi-live-dns/src/./gandi-live-dns.py", line 25, in get_dynip print ('Checking dynamic IP: ' , r._content.strip('\n')) TypeError: a bytes-like object is required, not 'str'

Btw, thanks for the help. 👍

I may be wrong but my feeling is that the issue is with the configuration file.
Either it is not properly named, not reachable by the script or having a wrong encoding.
I am adding my configuration file if this can help somehow.

If not, I must say I am stuck with ideas.

in python3 the requests library will return unicode string

try adding .decode('utf-8')

    r = requests.get(ifconfig_provider)
   print 'Checking dynamic IP: ' , r._content.decode('utf-8').strip('\n')
return r.content.decode('utf-8').strip('\n')

there are at least 2 open pull requests for python3 suppport

for example #35

you can try running that one instead

Hi nomwerp,

I try to add the utf-8 details and… there is some improvement. I doesn't have the type-error message anymore. But now I've got a "IndexError: list index out of range" error.
The parsing seems causing the issues :

`if name == "main":
parser = argparse.ArgumentParser()
parser.add_argument('-v', '--verbose', help="increase output verbosity", action="store_true")
parser.add_argument('-f', '--force', help="force an update/create", action="store_true")
args = parser.parse_args()

main(args.force, args.verbose)`

I'm really new in python, and development in general (except css, html and some shortcut). It's a whole new univers for me to discover. ^_^“

Anyway, thanks for your help.

And CPC67128, thanks a lot for the help. 👍
