pymongo.errors.ConfigurationError：DNS 标签为空

问题描述

我正在用 python 制作 discord bot。我正在使用数据库 (https://account.mongodb.com/) 制作调平系统，但出现以下语法错误：pymongo.errors.ConfigurationError: A DNS label is empty。请帮帮我。

main.py:

import os
import discord
import datetime
import levelsys

intents = discord.Intents.all()
bot = commands.Bot(command_prefix='$',intents=intents)

cogs = [levelsys]
for i in range(len(cogs)):
  cogs[i].setup(bot)

 # Setting permissions that a user should have to execute this command.

print('Server Running')
bot.run(os.getenv('token'))

levelsys.py:

import discord

          if i == 11:
            break
        await ctx.channel.send(embed=embed)

def setup(bot):
  bot.add_cog(levelsys(bot))

错误：

pymongo.errors.ConfigurationError: A DNS label is empty.

请帮助我并告诉我是否还有其他错误需要修复。非常感谢！

解决方法

猜测您的问题是连接字符串； “SRV”模式下的 mongodb 使用 DNS 来确定副本集/分片的详细信息。
