如何使用tkinter发送邮件

可以使用Python内置的smtplib和tkinter库来实现发送邮件的功能。以下是一个简单的示例代码：

import smtplib
from tkinter import *

def send_email():
    # 获取输入框中的内容
    sender = sender_entry.get()
    password = password_entry.get()
    receiver = receiver_entry.get()
    subject = subject_entry.get()
    content = content_text.get("1.0", END)

    # 设置邮件内容
    message = "From: {}\nTo: {}\nSubject: {}\n\n{}".format(sender, receiver, subject, content)

    # 连接SMTP服务器并发送邮件
    try:
        smtp_server = smtplib.SMTP_SSL("smtp.gmail.com", 465)
        smtp_server.login(sender, password)
        smtp_server.sendmail(sender, receiver, message)
        smtp_server.quit()
        result_label.config(text="邮件发送成功！", fg="green")
    except Exception as e:
        result_label.config(text="邮件发送失败：" + str(e), fg="red")

# 创建窗口和控件
window = Tk()
window.title("发送邮件")
sender_label = Label(window, text="发件人邮箱：")
sender_entry = Entry(window)
password_label = Label(window, text="邮箱密码：")
password_entry = Entry(window, show="*")
receiver_label = Label(window, text="收件人邮箱：")
receiver_entry = Entry(window)
subject_label = Label(window, text="邮件主题：")
subject_entry = Entry(window)
content_label = Label(window, text="邮件内容：")
content_text = Text(window, height=10)
send_button = Button(window, text="发送邮件", command=send_email)
result_label = Label(window, text="")

# 布局控件
sender_label.grid(row=0, column=0)
sender_entry.grid(row=0, column=1)
password_label.grid(row=1, column=0)
password_entry.grid(row=1, column=1)
receiver_label.grid(row=2, column=0)
receiver_entry.grid(row=2, column=1)
subject_label.grid(row=3, column=0)
subject_entry.grid(row=3, column=1)
content_label.grid(row=4, column=0)
content_text.grid(row=4, column=1)
send_button.grid(row=5, column=1)
result_label.grid(row=6, column=1)

# 运行窗口
window.mainloop()

在这个示例中，我们使用了SMTP_SSL协议连接Gmail的SMTP服务器，并通过登录验证和sendmail方法发送邮件。你可以根据自己的需要修改代码中的SMTP服务器地址和端口号，以及邮件内容的格式。
