Question

我想通过python将MSSQL数据发送到电报bot。这是我到目前为止所写的：

import time
import random
import datetime
import telepot
from telepot.loop import MessageLoop

import pyodbc
conn = pyodbc.connect('Driver={SQL Server};'
                      'Server=DESKTOP-OM8N0ER\SQLEXPRESS01;'
                      'Database=SmartHome;'
                      'Trusted_Connection=yes;')

cursor = conn.cursor()

def handle(msg):
    chat_id = msg['chat']['id']
    command = msg['text']

print ('Command received: %s') % command


if command == '/about':
    bot.sendMessage(chat_id, 'Hi, I\'m netrapsystembot')
elif command == '/random':
    bot.sendMessage(chat_id, random.randint(0,9))
elif command == '/time':
    bot.sendMessage(chat_id, str(datetime.datetime.now()))

elif command == '/sessions':
    cursor.execute('SELECT * FROM SmartHome.dbo.SensorData')
    for result in cursor.fetchall():
        bot.sendMessage(chat_id, result [0])

bot = telepot.Bot('803777982:AAEmtO98wjYcqoFqWXOSuYTeg6HFG6xUnwk')
MessageLoop(bot,handle).run_as_thread()
print ('Bot ready!')

while 1:
   time.sleep(10)

但是我目前在此行收到此错误消息：

print ('Command received: %s') % command

NameError：名称“ command”未定义

没有更多信息很难调试，但是我认为问题在于函数句柄的间距。您在函数句柄内部定义了命令，但尝试访问它而不返回变量句柄或一直调用到最后。这使我相信您的功能完全存在间距问题。现在，您的函数句柄实际上将在调用后发送一条消息，而不是仅初始化两个变量而不使用它们。

import time
import random
import datetime
import telepot
from telepot.loop import MessageLoop

import pyodbc
conn = pyodbc.connect('Driver={SQL Server};'
                      'Server=DESKTOP-OM8N0ER\SQLEXPRESS01;'
                      'Database=SmartHome;'
                      'Trusted_Connection=yes;')

cursor = conn.cursor()

def handle(msg):
    chat_id = msg['chat']['id']
    command = msg['text']

    print ('Command received: %s') % command


    if command == '/about':
        bot.sendMessage(chat_id, 'Hi, I\'m netrapsystembot')
    elif command == '/random':
        bot.sendMessage(chat_id, random.randint(0,9))
    elif command == '/time':
        bot.sendMessage(chat_id, str(datetime.datetime.now()))

    elif command == '/sessions':
         cursor.execute('SELECT * FROM SmartHome.dbo.SensorData')
         for result in cursor.fetchall():
             bot.sendMessage(chat_id, result [0])

bot = telepot.Bot('803777982:AAEmtO98wjYcqoFqWXOSuYTeg6HFG6xUnwk')
MessageLoop(bot,handle).run_as_thread()
print ('Bot ready!')

while 1:
   time.sleep(10)

但是，您没有将消息传递到任何地方的句柄中，因此该功能不会在当前状态下执行。
