我正在设置一个Facebook Messenger机器人，该机器人可以在我的笔记本电脑上远程执行代码（即截屏，显示消息）。当我从Messenger发出“ msg hello”消息时，机器人会使用Tkinter显示带有“ hello”的消息框。
程序返回错误：
RuntimeError: main thread is not in main loop
我尝试使用以下命令运行Tkinter：
root = tkinter.Tk()
root.mainloop()
但是程序只是冻结在那里（就像while True循环一样
这是我的主烧瓶应用程序的代码：
from flask import Flask, request
from pymessenger.bot import Bot
from functions.message_box import msg_box
app = Flask(__name__)
ACCESS_TOKEN = 'my token' # I removed these tokens on purpose
VERIFY_TOKEN = 'my token'
bot = Bot(ACCESS_TOKEN)
@app.route("/", methods=['GET', 'POST'])
def receive_message():
if request.method == 'GET':
# Assuming the request is from facebook's verfication
token_sent = request.args.get("hub.verify_token")
return verify_fb_token(token_sent)
else:
# get whatever message a user sent the bot
output = request.get_json()
for event in output['entry']:
messaging = event['messaging']
for message in messaging:
if message.get('message'):
#Facebook Messenger ID for user so we know where to send response back to
recipient_id = message['sender']['id']
# get code from the message
text = message['message'].get('text')
code = text[:text.find(' ')] # find the first word in the message
if code == 'msg':
msg = text[text.find(' ') + 1:] # get the message except the code
msg_box(msg)
send_message(recipient_id, f'Sent: {msg}')
return "Message Processed"
def verify_fb_token(token_sent):
if token_sent == VERIFY_TOKEN:
return request.args.get("hub.challenge")
return 'Invalid verification token'
#uses PyMessenger to send response to user
def send_message(recipient_id, response):
#sends user the text message provided via input response parameter
bot.send_text_message(recipient_id, response)
return "success"
if __name__ == "__main__":
app.run()
这是来自message_box.py的代码（用于在窗口上显示消息框）：
'''
Purpose: Display msg box on screen
'''
import tkinter
from tkinter import messagebox
# hide main window
root = tkinter.Tk()
# root.mainloop()
root.withdraw()
def msg_box(msg):
messagebox.showinfo("Information", msg)
return 1
