Exception in thread Thread-25 with my keylogger Python

Question

I have this remote keylogger and it works fine at first to send the emails but after a few minutes it stops sending emails and it throws me this error:

Exception in thread Thread-25:
Traceback (most recent call last):
  File "C:\Users\Lisandro0\AppData\Local\Programs\Python\Python37\lib\threading.py", line 926, in _bootstrap_inner

    msg = _fix_eols(msg).encode('ascii')
UnicodeEncodeError: 'ascii' codec can't encode character '\xf1' in position 312: ordinal not in range(128)

I would appreciate reading the code as it is short.

I appreciate any help

The error message is clear:

...Python37\lib\smtplib.py...UnicodeEncodeError: 'ascii' codec can't encode character '\xf1' in position 312: ordinal not in range(128)

It seems that smtplib has problem encoding your mail content.

I did some source code reading. In smtplib.py:

    def sendmail(self, from_addr, to_addrs, msg, mail_options=(),
                 rcpt_options=()):
        """This command performs an entire mail transaction.

        The arguments are:
            - from_addr    : The address sending this mail.
            - to_addrs     : A list of addresses to send this mail to.  A bare
                             string will be treated as a list with 1 address.
            - msg          : The message to send.
            - mail_options : List of ESMTP options (such as 8bitmime) for the
                             mail command.
            - rcpt_options : List of ESMTP options (such as DSN commands) for
                             all the rcpt commands.

        msg may be a string containing characters in the ASCII range, or a byte
        string.  A string is encoded to bytes using the ascii codec, and lone
        \\r and \\n characters are converted to \\r\\n characters.

Look here:

msg may be a string containing characters in the ASCII range, or a byte string

If you want to send mail of non-ascii content, you can encode the content into a byte string first.

(By the way, if I got it right, your question title is somewhat off the point, failing to grasp the key of your problem.)

Could you explain or give me an idea of how to insert that code in my source code, I've only been learning python for a few days, I only know html, css and php, but if you could help me I would appreciate it very much. By: thanks for the previous answer I already understood the problem but I still don't know how to solve it — Tomy ruby, Sep 18 '20 at 03:08
In your function `sendmail`, there is a line of code which calls smtplib's sendmail method: `server.sendmail(email, email, message)` As the doc string said, `sendmail` can accept a byte-string or a string. To pass it a byte-string rather than a string which will error when `message` is non-ascii, you need to convert `message` to byte-string type. Maybe you can try adding some type-converting stuff like `message = message.encode('utf8')` before calling `server.sendmail`. — fishoverflow, Sep 18 '20 at 03:47
Note you can mess around in a session to explore these things: ```python >>> s = '中文' >>> t = s.encode('utf8') >>> type(s) >>> type(t) >>> ``` You can also do some searching regarding to string and byte-string in python. — fishoverflow, Sep 18 '20 at 03:47
