(tkinter) ConnectionRefusedError: [WinError 10061] 由於目標機器主動拒絕，無法建立連接

Question

我嘗試使用不同的端口並在互聯網上找到解決方案，但我仍然無法修復它。 我嘗試將 localhost 更改為 127.0.0.1 並嘗試將端口號更改為所有類型的值，但仍然無法正常工作。 非常感謝您的幫助。

import tkinter
import smtplib
import socket

from email.parser import Parser

smtp = smtplib.SMTP

user = ""
password = ""

def connect():
    print(msg_entry.get())

    smtp = smtplib.SMTP("localhost", 587)
    #smtp.login(user,password)
    smtp.sendmail(from_entry.get(), to_entry.get(), msg_entry.get())
    smtp.quit()

app = tkinter.Tk()
app.title("test")


to_label = tkinter.Label(app,text="To:")
to_entry = tkinter.Entry(app)

from_label = tkinter.Label(app,text="From:")
from_entry = tkinter.Entry(app)

send_button = tkinter.Button(app,text="send",command=connect)

msg_label = tkinter.Label(app,text="Email:")
msg_entry = tkinter.Entry(app,width=50)
#pack(add) the widget to the app.
to_label.pack()
to_entry.pack()

from_label.pack()
from_entry.pack()

msg_label.pack()
msg_entry.pack()

send_button.pack()

#draw the window, have this at the end
app.mainloop()

每當我單擊發送時，我都會收到錯誤消息：

您需要在localhost上有一個服務器才能使其工作，我推薦PaperCut ，您也可能想查看我的這篇關於如何創建基本 smtp 郵件服務器的帖子。
