如何将我的python逻辑应用到tkinter GUI中？这是一个简单的GET请求程序
如何将我的python逻辑应用到tkinter GUI中？这是一个简单的GET请求程序
提问于 2020-09-29 01:14:21
我在试着做一个发送短信的程序。我唯一的问题是我不能让它用tkinter做一些事情。如果这听起来令人困惑，很抱歉，英语不是我的母语，我会尽力解释。
这是一个简单的GET请求，用于通过我的API发送SMS文本：
# GET
import requests
to = input("Enter Receiver: ")
fromm = input("Enter Sender: ")
message = input("Enter Message: ")
payload = {'to': to, 'from': fromm, 'message': message, 'email': '@example.com', 'api_secret': '123456789abcdefg'}
r = requests.get('https://example.com/dashboard/api',params=payload)
print(r.text)一旦发送了这个Get请求，我们就会得到一个确认消息已经发送的json响应。
下面是我的带有tkinter的GUI的样子：
from tkinter import *
def send_message():
print('sent')
def clear_text():
print('cleared')
#window object
app = Tk()
# Sender
Sender_text = StringVar()
Sender_label = Label(app, text='Sender', font=('bold', 14), pady=20)
Sender_label.grid(row=0, column=0, sticky=W)
Sender_entry = Entry(app, textvariable=Sender_text)
Sender_entry.grid(row=0, column=1)
# Receiver
Receiver_text = StringVar()
Receiver_label = Label(app, text='Receiver', font=('bold', 14))
Receiver_label.grid(row=0, column=2, sticky=W)
Receiver_entry = Entry(app, textvariable=Receiver_text)
Receiver_entry.grid(row=0, column=3)
# Message
Message_text = StringVar()
Message_label = Label(app, text='Message', font=('bold', 14))
Message_label.grid(row=1, column=0, sticky=W)
Message_entry = Entry(app, textvariable=Message_text)
Message_entry.grid(row=1, column=1)
# Buttons
send_btn = Button(app, text='Send', width=12, command=send_message)
send_btn.grid(row=2, column=0, pady=20)
clear_btn = Button(app, text='Clear', width=12, command=clear_text)
clear_btn.grid(row=2, column=1)
app.title('SMS')
app.geometry('430x145')
#start
app.mainloop()我花了大约两个小时来学习如何制作GUI，但到目前为止，我只是迷失了方向。对于如何将逻辑实现到GUI中，我没有实际的想法。如何使文本和按钮工作？我该在哪里添加函数？我真的迷路了。
非常感谢您的帮助。

您可以简单地将逻辑(将所有input()替换为xxx.get())放入函数send_message()中
import requests
def send_message():
receiver = Receiver_text.get()
sender = Sender_text.get()
message = Message_text.get()
payload = {'to': receiver, 'from': sender, 'message': message,
'email': '@example.com', 'api_secret': '123456789abcdefg'}
r = requests.get('https://example.com/dashboard/api', params=payload)
print(r.text)Stack Overflow用户

参考你的GUI让我们给你的代码更多一点的结构，这样它就更容易看到正在发生的事情。我将窗口的设置放在一个函数my_window中，从main中传递参数app给它。按下按钮send sender_text、receiver_text和message_text的值可通过使用sender_text.get()、receiver_text.get()等获得。这些函数的结果通过lambda函数传递给函数send_message。
from tkinter import Tk, StringVar, Label, Entry, Button, W
def send_message(snd_txt, rcv_txt, msg_txt):
print(f'sent: {snd_txt}, {rcv_txt}, {msg_txt}')
def clear_text():
print('cleared')
def my_window(app):
# Sender
sender_text = StringVar()
sender_label = Label(app, text='Sender', font=('bold', 14), pady=20)
sender_label.grid(row=0, column=0, sticky=W)
sender_entry = Entry(app, textvariable=sender_text)
sender_entry.grid(row=0, column=1)
# Receiver
receiver_text = StringVar()
receiver_label = Label(app, text='Receiver', font=('bold', 14))
receiver_label.grid(row=0, column=2, sticky=W)
receiver_entry = Entry(app, textvariable=receiver_text)
receiver_entry.grid(row=0, column=3)
# Message
message_text = StringVar()
message_label = Label(app, text='Message', font=('bold', 14))
message_label.grid(row=1, column=0, sticky=W)
message_entry = Entry(app, textvariable=message_text)
message_entry.grid(row=1, column=1)
# Buttons
send_btn = Button(
app, text='Send', width=12,
command=lambda: send_message(sender_text.get(), receiver_text.get(), message_text.get()))
send_btn.grid(row=2, column=0, pady=20)
clear_btn = Button(app, text='Clear', width=12, command=clear_text)
clear_btn.grid(row=2, column=1)
def main():
app = Tk()
app.title('SMS')
app.geometry('430x145')
my_window(app)
app.mainloop()
if __name__ == '__main__':
main()但是，更常见的做法是将my_window定义为class，并将此class的函数定义为clear_text和send_message方法，这提供了更大的灵活性。
from tkinter import Tk, StringVar, Label, Entry, Button, W
class my_window:
def __init__(self, app):
# Sender
self.sender_text = StringVar()
sender_label = Label(app, text='Sender', font=('bold', 14), pady=20)
sender_label.grid(row=0, column=0, sticky=W)
sender_entry = Entry(app, textvariable=self.sender_text)
sender_entry.grid(row=0, column=1)
# Receiver
self.receiver_text = StringVar()
receiver_label = Label(app, text='Receiver', font=('bold', 14))
receiver_label.grid(row=0, column=2, sticky=W)
receiver_entry = Entry(app, textvariable=self.receiver_text)
receiver_entry.grid(row=0, column=3)
# Message
self.message_text = StringVar()
message_label = Label(app, text='Message', font=('bold', 14))
message_label.grid(row=1, column=0, sticky=W)
message_entry = Entry(app, textvariable=self.message_text)
message_entry.grid(row=1, column=1)
# Buttons
send_btn = Button(app, text='Send', width=12, command=self.send_message)
send_btn.grid(row=2, column=0, pady=20)
clear_btn = Button(app, text='Clear', width=12, command=self.clear_text)
clear_btn.grid(row=2, column=1)
def send_message(self):
print(f'sent: {self.sender_text.get()}, '
f'{self.receiver_text.get()}, '
f'{self.message_text.get()}')
def clear_text(self):
self.sender_text.set('')
self.receiver_text.set('')
self.message_text.set('')
print('cleared')
def main():
app = Tk()
app.title('SMS')
app.geometry('430x145')
my_window(app)
app.mainloop()
