pymongo.errors.ConfigurationError：DNS 标签为空

Question

我正在用 python 制作 discord 机器人。我正在使用数据库（https://account.mongodb.com/）制作调平系统，我收到了这个语法错误：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
from discord.ext import commands
from pymongo import MongoClient
import urllib.parse

bot_channel = 798127930295058442
talk_channels = [690995360834912327]

level = ['new', 'old_new', 'Master Oogway']
levelnum = [5, 15, 30]

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

cluster = MongoClient("mongodb+srv://Myself:" + urllib.parse.quote("stackoverflow") + "@cluster0.4h226.mongodb.n...")

leveling = cluster["discord"]["leveling"]

class levelsys(commands.Cog):
    def __init__(self, bot):
      self.bot = bot

    @commands.Cog.listener()

          for x in rankings:
            rank += 1
            if stats["id"] == x["id"]:
              break

            pass
          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.

请帮帮我，告诉我是否还有其他需要修复的错误。非常感谢！

猜测您的问题在于连接字符串； “SRV”模式下的 mongodb 使用 DNS 来确定副本集/分片详细信息。
