奇怪的电报机器人问题

Question

我有一个托管电报机器人的 python Heroku 应用程序。它正在使用 python-telegram-bot。除了 1 个命令外，它工作得很好。 该命令是 /reputation。

请阅读最后的注释。

在我们的项目目录中：

bot.py
Procfile
requirements.txt
reptation.json

命令处理函数是：

# code from bot.py, from line 75 to line 105, Additional comments added
    def reputation(update, context):
    sendername = update.message.from_user.username
    print(sendername)
    if context.args != [] and sendername == "[censored for privacy]": # +sendername check
        # Add reputation to someone, 3 args: target (@username), operation (+, -, =), amount (1)
        target = context.args[0]
        operation = context.args[1]
        amount = context.args[2]
        f = open("reputation.json", "r")
        reputationDict = json.load(f)
        f.close()
        amountTarget = reputationDict[target] 
        if operation == "+":
            amountTarget += amount
        elif operation == "-":
            amountTarget -= amount
        elif operation == "=":
            amountTarget = amount
        out_file = open("reputation.json", "w")
        json.dump(reputationDict, out_file, indent = 6)
        out_file.close()
    elif context.args == []:
        # send reputation
        reputationDict = json.load(f)
        f.close()
        print("\n\n")
        print(reputationDict)
        ReputationMessage = parseReputationMessage(reputationDict)
        # parseReputationMessage is a function that I created behind this piece of code. It takes the dict and returns a string with the reputation message. Here is it:
        """
        def parseReputationMessage(rd):
    textxtxtxttxtx = "????Group Reputation | Репутация Группы:????\n" + rd[rd.keys[0]] + ":" + rd[rd.values[0]] + "\n" + rd[rd.keys[1]] + ":" + rd[rd.values[1]] + "\n" + rd[rd.keys[2]] + ":" + rd[rd.values[2]] + "\n" + rd[rd.keys[3]] + ":" + rd[rd.values[3]] + "\n" + rd[rd.keys[4]] + ":" + rd[rd.values[4]]
    return textxtxtxttxtx
        """
        update.message.reply_text(ReputationMessage)
    print(context.args)
    update.message.reply_text(context.args)

注意事项：

我没有忘记创建字典：

# bot.py, line 10    
reputationDict = {}

别以为我忘记了处理程序

# code from bot.py, line 126
dp.add_handler(CommandHandler("reputation", reputation, pass_args=True))

机器人的其余部分没问题。请告诉我有什么问题。

编辑：这是 Heroku 日志（在我调用不带 args 的命令之后）：

Answer 1

撤销您通过日志公开的机器人令牌，否则任何人都可以使用您的机器人。

日志也显示了这一点：

2021-08-22T12:31:06.705938+00:00 app[web.1]: 2021-08-22 12:31:06,705 - __main__ - WARNING - Update "{'update_id': ...}" caused error "local variable 'f' referenced before assignment"
...
2021-08-22T12:32:37.466462+00:00 app[web.1]: 2021-08-22 12:32:37,466 - __main__ - WARNING - Update "{'update_id': ...}" caused error "Expecting ',' delimiter: line 3 column 2 (char 21)"

这告诉您代码中存在导致异常的问题。 python-telegram-bot 旨在使运行时的异常不会关闭您的机器人。我的猜测是您注册了一个错误处理程序，它只记录异常消息，隐藏了实际的回溯。

要了解有关 PTB 中异常处理的更多信息，请查看此wiki page 和此example。
