【问题描述】：

我试图发出警告命令，但我失败了，所以我在这里请求有更多经验的人帮助我

这是我的代码（我没有使用 json 文件的经验）

我希望你能帮助我。

@client.event
async def on_member_join(member):
    warnsn = 0
    with open('warns.json', 'r') as f:
        warns = json.load(f)

    warns[str(member)] = warnsn

    with open('warns.json', 'w') as f:
        json.dump(warns, f, indent=4)

@client.event
async def on_member_remove(member):
    warnsn = 0
    with open('warns.json', 'r') as f:
        warns = json.load(f)

    warns.pop(str(member))

    with open('warns.json', 'w') as f:
        json.dump(warns, f, indent=4)

@client.command()
async def warn(ctx, member: discord.Member=None, *, arg):
    warnsn = 0
    with open('warns.json', 'r') as f:
        warns = json.load(f)

    warns[str(member)] = warnsn + 1

    with open('prefixes.json', 'w') as f:
        json.dump(warns, f, indent=4)

    await ctx.send(f'{member} has been warned')

@client.command()
async def warns(ctx, member: discord.Member=None):
    warnsn = 0
    with open('warns.json', 'r') as f:
        warns = json.load(f)

    warns[str(member)] = warns
    await ctx.send(f'{member} has {warnsn} warns')

【问题讨论】：

到底是什么问题？
如果您对 .json 文件没有太多经验，请使用 .txt 文件，如果 .json 文件比较难，则更容易使用

【解决方案1】：

问题是你每次都将warnsn定义为0，你只需要将JSON文件中的成员加1

@client.command()
async def warn(ctx, member: discord.Member=None, *, arg):
    with open('warns.json', 'r') as f:
        warns = json.load(f)

    warns[str(member)] += 1

    with open('prefixes.json', 'w') as f:
        json.dump(warns, f, indent=4)

    await ctx.send(f'{member} has been warned')

@client.command()
async def warns(ctx, member: discord.Member=None):
    with open('warns.json', 'r') as f:
        warns = json.load(f)

    warnsn = warns[str(member)]
    await ctx.send(f'{member} has {warnsn} warns')
