从 tkinter.Text 获取输入并打印结果

问题描述

我一直在开发一个用于清理 URL 和 IP 地址的 GUI 程序。目前，我想清理输入和打印结果的 “打印” 按钮不起作用。我的其他功能按照我希望的方式工作，这些功能已经过测试。

在 printOut() 函数中，该代码片段在我之前使用的 CLI 版本中有效。

我已经包含了我的 GUI 界面的屏幕截图，以显示我想要的结果。对我的代码的任何帮助将不胜感激。

import tkinter as tk
from tkinter import messageBox
from tkinter import filedialog

# help @R_175_4045@ion -- works
def help_info():
    h = messageBox.showinfo("Help","This program is used to defang/sanitise URLs and IP addresses.\n"
                                    "\nEnter a URL or IP address into the top input field and have it printed to the 'Results' output or,save it to a file.")

# Print sanitised results out
# not working
def printOut():
    url = inputTextBox.get(1.0,"end-1c")

    if "http" in url:
        url = url.replace("http","hxxp")
        url = url.replace(":","[:]")
        url = url.replace(".","[.]")

    elif "https" in url:
        url = url.replace("https","hxxps")
        url = url.replace(":","[.]")

    elif "http" not in url:
        url = url.replace(".","[.]")

    elif "https" not in url:
        url = url.replace(".","[.]")
    return(url)

# save output to a file -- works
def save_as():
    save_output = filedialog.asksaveasfile()


# quit the program -- works
def quit_program():
    are_you_sure = messageBox.askquestion("Quit","Are you sure?")
    if are_you_sure == 'yes':
        mainWindow.destroy()
    else:
        mainWindow.mainloop()


# Create mainWindow,not resizeable
mainWindow = tk.Tk()
mainWindow.title("Defang")
mainWindow.geometry("585x355-730-400")
mainWindow.resizable(False,False)

# label for user input
input_label = tk.Label(mainWindow,text="Enter URL(s) and or IP Address(s)",font="Arial 9")
input_label.place(x=7,y=5)

# input textBox
inputTextBox = tk.Text(mainWindow,width=70,height=8)
inputTextBox.place(x=10,y=25)

# label for output
output_label = tk.Label(mainWindow,text="Results",font="Arial 9")
output_label.place(x=7,y=165)

# results textBox
outputTextBox = tk.Text(mainWindow,height=8)
outputTextBox.place(x=10,y=185)

# help button
help_button = tk.Button(mainWindow,text="Help",padx=20,pady=0,command=help_info)
help_button.place(x=100,y=325)

# print button
print_button = tk.Button(mainWindow,text="Print",command=printOut)
print_button.place(x=200,y=325)

# save button
save_button = tk.Button(mainWindow,text="Save",command=save_as)
save_button.place(x=300,y=325)

# exit button
exit_button = tk.Button(mainWindow,text="Exit",command=quit_program)
exit_button.place(x=400,y=325)

# run the program
mainWindow.mainloop()

解决方法

printOut 函数不起作用，因为在替换 URL 后您没有将它插入到 outputTextbox 中。在 printout 函数中的所有条件之后，您应该从中替换 return url 代码。

outputTextbox.insert(1.0,url)
