Discord Chess.com 统计机器人？

Question

这是我第一次创建 Discord 机器人，我正在尝试从 chess.com API 中提取数据。当您在 Discord 频道中输入 !chessresult user 时，如果用户赢得了上一场 chess.com 游戏，我希望机器人返回。我知道我的机器人已连接，因为我可以让机器人回复文本，但我很难让它提取数据。任何帮助，将不胜感激。谢谢！

import discord
import requests
from discord.ext import commands

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

@bot.event
async def on_ready():
    print('We have logged in as {0.user}'.format(bot))

@bot.event
async def on_message(message):
     if message.content == "hello":
        await message.channel.send('hello')

@bot.command()
async def chessresult(ctx, username: str):
    try:
        # Fetch the recent games of the user from the Chess.com API
        response = requests.get(f'https://api.chess.com/pub/player/{username}/games/archives')
        response.raise_for_status()  # Raise an error for bad responses
        archives = response.json()['archives']

        if not archives:
            await ctx.send(f"No games found for user {username}")
            return

        # Use the most recent archive to get the games
        last_month_url = archives[-1]
        games_response = requests.get(f"{last_month_url}/pgn")
        games_response.raise_for_status()

        # Extract games from the PGN
        games = games_response.text.split("\n\n\n")

        # Extract the result of the most recent game
        last_game = games[-2]  # The last item is empty, so take the second last
        result_line = [line for line in last_game.split("\n") if "Result" in line][0]
        result = result_line.split('"')[1]

        await ctx.send(f"Last game result for {username}: {result}")

    except requests.RequestException as e:
        await ctx.send(f"Error fetching data for {username}: {str(e)}")


bot.run('KEY')

我尝试了各种方法，但还没有走得太远。这是我第一次编写机器人程序。

您可以解析 json 响应，而不是在第二个请求中从国际象棋 API 请求 PGN 文件：

with requests.Session() as sess:
  
    # get the archives
    resp = sess.get(
        f'https://api.chess.com/pub/player/{username}/games/archives')
    resp.raise_for_status()
  
    last_game = resp.json().get('archives', [False])[-1]
    if not last_game:
        #error
  
    # get the last month
    resp = sess.get(f"{last_month_url}")
    resp.raise_for_status()
  
    game = resp.json().get('games', [{}])[-1].get('pgn')
    if not game:
        #error

# now session is closed
await ctx.send(game)

长话短说，我无法重现您的错误。看起来 chess.com API 不需要密钥或身份验证，所以事实并非如此。您可以添加日志语句，并确保您不会在其他地方遇到被您的 try/ except 语句之一吞没的错误。
