如何设置频道的角色权限？ -Java JDA

Question

如何在测试频道中设置角色列表的权限？ 我试过了，但它只设置了最后一个角色：

            Category category = guild.getCategoryById(Categ);
            TextChannel channel1 = guild.createTextChannel("ticket-" + EndlessBungeeTickets.instance.sql.getTicket(username)).setParent(category).addPermissionOverride(guild.getMember(user), EnumSet.of(Permission.VIEW_CHANNEL, Permission.MESSAGE_WRITE), null).addPermissionOverride(guild.getPublicRole(), null, EnumSet.of(Permission.VIEW_CHANNEL, Permission.MESSAGE_WRITE)).complete();
            //RolesWR is equal to a list of roles for ex. [738036146151358504, 814517406067589122, 789617469605281843]
            //But it only sets permission to the last role of the list
            RolesWR.forEach(ruolo -> {
                System.out.println(ruolo);
                channel1.getManager().putPermissionOverride(guild.getRoleById(ruolo), EnumSet.of(Permission.VIEW_CHANNEL, Permission.MESSAGE_WRITE), null).queue();
            });

您应该在调用队列之前添加所有覆盖。

Category category = guild.getCategoryById(Categ);
TextChannel channel1 = guild.createTextChannel("ticket-" + EndlessBungeeTickets.instance.sql.getTicket(username)).setParent(category).addPermissionOverride(guild.getMember(user), EnumSet.of(Permission.VIEW_CHANNEL, Permission.MESSAGE_WRITE), null).addPermissionOverride(guild.getPublicRole(), null, EnumSet.of(Permission.VIEW_CHANNEL, Permission.MESSAGE_WRITE)).complete();
ChannelManager manager = channel1.getManager();
for (long roleId : RolesWR) {
  manager.putPermissionOverride(guild.getRoleById(roleId), EnumSet.of(Permission.VIEW_CHANNEL, Permission.MESSAGE_WRITE), null);
}
manager.queue(); // this will add all overrides at once

直接将它们全部添加到ChannelAction 会更好：

String ticketId = EndlessBungeeTickets.instance.sql.getTicket(username);
// Use variables to make the code more readable and remove duplicate allocations
EnumSet<Permission> permissions = EnumSet.of(Permission.VIEW_CHANNEL, Permission.MESSAGE_WRITE);
// Use the channel action properly by adding all overrides to it
ChannelAction<TextChannel> manager = category.createTextChannel("ticket-" + ticketId)
  .addPermissionOverride(guild.getMember(user), permissions, null) // grant access to the user
  .addPermissionOverride(guild.getPublicRole(), null, permissions); // deny access to @everyone
for (long roleId : RolesWR) { // Make sure IDs are stored as longs
   // grant access to the roles
  manager.addPermissionOverride(guild.getRoleById(roleId), permissions, null);
}
// Creates the channel with the overrides already applied, without blocking your thread too!
manager.queue();
