Question

嘿我正在尝试创建一个基于GUI的应用程序，可用于枚举pcap文件，所需的功能就是当用户点击枚举时，另一个窗口出现，用户可以输入应该运行的文件名

仅仅是为了测试我目前正在使用原始bash命令输入，但不幸的是，这对我不起作用。

以下是我的代码： -

from tkinter import *
import tkinter
import subprocess
window = tkinter.Tk()
window.minsize(300,300)
#back = tkinter.Tk()
window.title("Extractor")
e1 = Entry(window)

def disp():
        subprocess.call([e1.get()])
def callback():
        Label(window,text="Command").grid(row=0)
        e1 = Entry(window)
        e1.insert(10,"Please input")
        e1.grid(row=0,column=1)
        process = tkinter.Button(window,text="GO",command=disp)
        process.grid(row=10,column=5)

toplabel=tkinter.Label(window,text="Enumeration tool for PCAP")


enum = tkinter.Button(window,text ="Enumerate",command=callback)
enum.grid(row=10)
window.mainloop()

产生错误： -

Exception in Tkinter callback
Traceback (most recent call last):
  File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 1544, in __call__
    return self.func(*args)
  File "GUI.py", line 11, in disp
    subprocess.call([e1.get()])
  File "/usr/lib/python2.7/subprocess.py", line 172, in call
    return Popen(*popenargs, **kwargs).wait()
  File "/usr/lib/python2.7/subprocess.py", line 394, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1047, in _execute_child
    raise child_exception
OSError: [Errno 13] Permission denied

我需要帮助调用另一个窗口框架中的另一个窗口，然后如何放置一些命令，如bash <input>，这样bash总是被隐藏，只有输入执行脚本＆amp;我该如何解决这个错误。

您的代码只需很少的更改即可使用：

...

window.title("Extractor")
e1 = None # <- your were creating two instances of your entry, one in 
          # global namespace and other local to the functions. Why?

def disp():
        subprocess.call([e1.get()]) # no need for for global, its a read op
def callback():
        global e1 # refer to global e1 on writes
        Label(window,text="Command").grid(row=0)
        e1 = Entry(window)

...

您可以创建除Tk()根窗口之外的其他窗口，调用tkinter.Toplevel(root)来实例化新的根子窗口。
