Password with @ in it fails when using DSN

[troy-system76]

I use Version: 1.23.2 of mycli.

I have this DSN:

myAlias = mysql://username:passwordWith@and@m@host.rds.amazonaws.com:5555/mydb

(a bunch of stuff is changed there)

But when I go:

mycli myAlias

I receive this error:

(2003, "Can't connect to MySQL server on '}gg$' ([Errno -2] Name or service not known)")

If I encode the uri with %40 for the @ signs I receive this error:

Traceback (most recent call last):
  File "/usr/bin/mycli", line 33, in <module>
    sys.exit(load_entry_point('mycli==1.23.2', 'console_scripts', 'mycli')())

  File "/usr/lib/python3.9/urllib/parse.py", line 654, in unquote
    if '%' not in string:
TypeError: argument of type 'NoneType' is not iterable

Do you know how I can make mycli work with @ in the passwords?

Thanks in advance

Hi!

What happens if you run this command?

python -c 'from urllib.parse import urlparse, unquote; uri = urlparse("mysql://username:passwordWith@and@m@host.rds.amazonaws.com:5555/mydb"); print(uri.username); print(uri.password);'

Here I get

username
passwordWith@and@m

suggesting that @ symbols alone are not the source of your issue.

Thanks for the quick response. When I run:

python -c 'from urllib.parse import urlparse, unquote; uri = urlparse("mysql://username:passwordWith@and@m@host.rds.amazonaws.com:5555/mydb"); print(uri.username); print(uri.password);'

I get:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named parse

if I run:

python3 -c 'from urllib.parse import urlparse, unquote; uri = urlparse("mysql://username:passwordWith@and@m@host.rds.amazonaws.com:5555/mydb"); print(uri.username); print(uri.password);'

I get the same response you do.

/usr/bin/mycli has this:

!/usr/bin/python3

Not that that means much. it's a tiny script that looks like it calls something else (apologies, I have very little python experience)

You might want to take a look at the python3 -c output but using your actual DSN instead of the example we are using.

Our example works for both of us, but maybe your actual DSN does not.

when # in the url will get error python -c 'from urllib.parse import urlparse, unquote; uri = urlparse("mysql://root:pken3I#l1@10.10.20.211:29119/mydatabasess"); print(uri.username); print(uri.password);' --------> None None

[troy-system76]

Going out on a limb I'd say that I and @liygzting are missing a library that enables us to properly use special characters in passwords.

same issue , because my password contains '#' symbol

when # in the url will get error python -c 'from urllib.parse import urlparse, unquote; uri = urlparse("mysql://root:pken3I#l1@10.10.20.211:29119/mydatabasess"); print(uri.username); print(uri.password);' --------> None None

Me too

url encoding # character into %23 as suggested here https://github.com/dbcli/mycli/issues/585#issuecomment-373989269 worked well for me!
