Python利用tkinter和socket实现端口扫描

题目

请设计并实现一款主机端口扫描程序。程序根据用户输入的域名或IP地址，可以查询该主机的开放的端口号。 例如：

并有一定的异常处理

参考code

import tkinter
from tkinter import *
import socket
import tkinter.messagebox


class CheckPort:
  def __init__(self):
      window = Tk()
      window.title("端口扫描")
      window.geometry("600x500")
      frame1 = Frame(window)
      frame1.pack()
      Label(frame1, text="IP地址、域名：", bg="#f0f0f0").grid(row=0, column=1, pady=3)
      Label(frame1, text="起始端口（最小为1）：", bg="#f0f0f0").grid(row=1, column=1, pady=3)
      Label(frame1, text="结束端口（最大为65535）：", bg="#f0f0f0").grid(row=2, column=1, pady=3)
      self.searchText = StringVar()
      Entry(frame1, textvariable=self.searchText, justify=LEFT).grid(row=0, column=2)
      self.originPort = IntVar()
      Entry(frame1, textvariable=self.originPort, justify=LEFT).grid(row=1, column=2)
      self.endPort = IntVar()
      Entry(frame1, textvariable=self.endPort, justify=LEFT).grid(row=2, column=2)
      Button(frame1, text="扫描", command=self.getRes).grid(row=3, column=1, columnspan=2, pady=3)
      frame2 = Frame(window).pack()
      self.resText = Text(frame2, height=50, width=500, wrap=WORD)
      self.resText.pack()

      window.mainloop()

  def getRes(self):
      try:
          ip = socket.gethostbyname(self.searchText.get())
          str1 = ""
          if 1 <= self.originPort.get() <= self.endPort.get() <= 65535:
              for port in range(self.originPort.get(), self.endPort.get() + 1):
                  try:
                      socket.setdefaulttimeout(1)
                      client = socket.socket()
                      client.connect((ip, port))
                      client.shutdown(1)
                      str1 += f"{ip}:{port}已开放\n"
                  except Exception as e:
                      str1 += f"{ip}:{port}未开放\n"
                      pass
              str1 += f"扫描完成\n"
              self.resText.insert(END, str1)
          else:
              self.errorHandle("请输入正确的端口号！")

      except:
          self.errorHandle("请输入正确的域名或者ip地址！")

  def errorHandle(self, message):
      tkinter.messagebox.showerror(title="error", message=message)
