单击按钮10次后，tkinter是否可以发送电子邮件？当按钮被按下10次时，我要在第10次发送消息““水低”。水结束了，我需要去充电。这是饮水机的按钮。该按钮与继电器相连。
答案 0 :(得分：2)
是的，这是可能的，而且非常简单。您可以添加一个功能，在按下10个按钮后显示一条消息。如果您想要弹出消息，则可以使用DECLARE @SQL VARCHAR(MAX)= 'SELECT '+ @sqlstring + ' FROM MyTable '
EXEC (@SQL)
模块显示弹出消息。
tkinter.messagebox要发送电子邮件，您必须使用其他库。我正在使用from tkinter import *
from tkinter.messagebox import *
root = Tk()
show_press = Label(root, text='You pressed the Button 0 times')
show_press.pack()
count = 0
def times_pressed():
global count
count+=1
if count >= 10:
# Code to be executed when "water is low"
showwarning("Water is Low", 'Water is over and it needs to be changed.')
show_press['text'] = 'You pressed the Button {} times'.format(count)
button = Button(root, text='Button', command = times_pressed)
button.pack()
root.mainloop()
。
要安装smtplib
smtplib
尽管我安装了python，但是
我在这个图书馆没有太多经验。我建议您看到pip install smtplib documentation。但是我做了一个从Gmail帐户发送电子邮件的功能。另外，如果您使用我的功能，建议您创建一个新帐户以发送电子邮件。
这是完整的代码：
smtplib电子邮件发送时，GUI的另一件事可能会冻结，直到发送电子邮件为止。要解决此问题，您需要使用import smtplib
from tkinter import *
def Send_Email(email, password, to, subject, message):
try:
# Only for gmail account.
with smtplib.SMTP('smtp.gmail.com:587') as server:
server.ehlo() # local host
server.starttls() # Puts the connection to the SMTP server.
# login to the account of the sender
server.login(email, password)
# Format the subject and message together
message = 'Subject: {}\n\n{}'.format(subject, message)
# Sends the email from the logined email to the receiver's email
server.sendmail(email, to, message)
print('Email sent')
except Exception as e:
print("Email failed:",e)
root = Tk()
show_press = Label(root, text='You pressed the Button 0 times')
show_press.pack()
count = 0
def times_pressed():
global count
count+=1
if count >= 10:
# Code to be executed when "water is low"
message = "Water is over and it needs to be changed."
Send_Email(
email='tmpaccount@gmail.com', # Gmail new account
password='test@123', # Its password
to='Your email address', # Receiver's email
subject='Water is Low', # Subject of mail
message=message ) # The message you want
show_press['text'] = 'You pressed the Button {} times'.format(count)
button = Button(root, text='Button', command = times_pressed)
button.pack()
root.mainloop()
模块和threading Thread函数。
要使用线程，您需要将其导入Send_Email(...)并必须在这样的线程中运行from threading import Thread函数
Send_Email(...)
