discord.py - 未返回更改的权限

Question

我希望我的机器人打印添加和删除的权限，但即使我更改了权限，我的机器人也没有返回任何内容

这是我的代码：

async def on_server_role_update(before, after):
    list_a = []
    list_b = []
    list_a.append(str([p[0] for p in before.permissions]))
    list_b.append(str([p[0] for p in after.permissions]))
    dif_add = set(list_b).difference(list_a)
    dif_rem = set(list_a).difference(list_b)
    print("Added Permissons: " + ", ".join(dif_add))
    print("Removed Permissons: " + ", ".join(dif_rem))

Answer 1

首先在更新的discord py中它不是on_server_role_update而是on_guild_role_update ，不再支持旧版本所以我建议你更新。

其次，在设置后尝试打印list_a和list_b ，你会看到你只获得所有权限名称的列表： ['add_reactions', 'administrator', 'attach_files', 'ban_members', ....怎么会你比较一下？

你也错过了非常重要的陈述：

if before.permissions != after.permissions:

你需要它，因为on_server_role_update aka on_guild_role_update将触发多个事件，如名称更改，描述更改，可提及的更改，位置更改，颜色更改等

所以对于一个很好的干净代码：

if before.permissions != after.permissions:
        diff = list(set(after.permissions).difference(set(before.permissions)))
        # diff will be a list which has changed roles and their state AFTER the change, example:
        # [('manage_channels', True), ('view_audit_log', True), ('manage_roles', True), ('manage_guild', False)]
        for changed_perm in diff:
            print(f"Changed role permission {changed_perm[0]} to {changed_perm[1]}")

示例输出：

Changed role permission manage_channels to True
Changed role permission view_audit_log to True
Changed role permission manage_roles to True
Changed role permission manage_guild to False
