discord.py ：按用户对 JSON 文件中的消息 ID 进行排序

Question

我目前正在制作一种票务系统。我想通过反应来做到这一点。

当用户点击反应时，会向特定频道发送一条消息。此消息 ID 保存在 JSON 文件中，应分配给单击反应的用户。但是如果我将用户和消息分别保存在 JSON 文件中，我不知道该消息属于哪个用户。如何将消息 ID 分配给用户？

我的代码：

@client.event
async def on_raw_reaction_add(reaction):
    ticketmess = 716263100638035969
    ticketlog = client.get_channel(716265124771397662)
    user = client.get_user(reaction.user_id)


    if reaction.message_id == ticketmess and reaction.emoji.id == 680827797165572117:
        with open(r'./tickets.json', 'r')as f:
            ticketchannels = json.load(f)
        if not f"{reaction.user_id}" in ticketchannels:

            ticketmess = await ticketlog.send('Ein User braucht Hilfe!')

            with open(r'./tickets.json', 'r')as f:
                ticketmessages = json.load(f)

                ticketmessages[f"{reaction.user_id}"] = f'{user} in {ticketmess.id}'

                with open(r'./tickets.json', 'w') as f:
                    json.dump(ticketmessages, f, indent=4)

Answer 1

代码如下所示：

@client.event
async def on_raw_reaction_add(reaction):
    ticketmsg = 716263100638035969
    ticketlog = client.get_channel(716265124771397662)
    user = client.get_user(reaction.user_id)

    if reaction.message_id == ticketmsg and reaction.emoji.id == 680827797165572117:

        # you already have loaded it in once, you don't need to read it again
        with open("tickets.json", "r") as fp:
            data = json.load(fp) 

        if f"{reaction.user_id}" not in data.keys():
            ticketmsg = await ticketlog.send("Ein User braucht Hilfe!")

            # you can just assign the message id to the user, no need for a string
            data[f"{reaction.user_id}"] = ticketmsg.id

            with open("tickets.json", "w+") as fp:
                json.dump(data, fp, sort_keys=True, indent=4) # kwargs are for beautification

您不需要f"{user} in {ticketmsg.id}"，因为您可以从密钥中获取用户。此外，用户名可以更改，因此将其放入文件中将被证明不是很有用。
如果您想获取用户名，只需从 json 中加载密钥并使用 client.get_user(ID_HERE)。

如果您想根据特定的消息 ID 搜索用户，您可以像这样遍历字典：

my_dict = {"key": "value", "foo": "bar"}

for k, v in my_dict.items():
    if v == "bar":
        print(k) # selecting the key based off of its value

# output:
# foo
