arrays - 使用 asn.1 的结构数组

Question

我正在学习编写 asn.1 语法。我希望 asn.1 提供编写序列数组的功能。它有一个相同类型的结构模式，一次又一次地重复，但有微小的修改。我想知道 ASN.1 是否允许我编写数组类型的语法来适应它而不是编写这种大语法。

gamePlayer {
gamePlayer {
    gamePlayer type: user (0)
    playerDetail  {
        name: player_1
        team: red
        ip: 10.3.3.1
        membership: level_2
    }
}
gamePlayer {
    gamePlayer type: user (0)
    playerDetail  {
        name: player_2
        team: blue
        ip: 10.3.3.2
        membership: level_4
    }
}
gamePlayer {
    gamePlayer type: ai (1)
    playerDetail  {
        name: ai_1
        team: red
        bot: bikeBot
    }
}
gamePlayer {
    gamePlayer type: ai (1)
    playerDetail  {
        name: ai_2
        team: blue
        bot: bikeBot
    }
}
gamePlayer {
    gamePlayer type: ai (1)
    playerDetail  {
        name: ai_3
        team: blue
        bot: carBot
    }
}

Answer 1

我会使用 ENUMERATED 作为玩家类型。 playerDetail 中的差异可以通过 OPTIONAL 成员来解决。游戏玩家数组将由 SEQUENCE OF 解决。

这是ASN.1模块的例子(我没测试过是否正确)游戏玩家模块

DEFINITIONS IMPLICIT TAGS ::= BEGIN

GamePlayers ::= SEQUENCE OF GamePlayer

Gameplayer ::= SEQUENCE {
   type ::=         ENUMERATED
                       {
                          user  (0)
                          ai    (1)

                       },
   playerDetail     PlayerDetail
}

PlayerDetail ::= SEQUENCE {
    name            UTF8STRING,
    team            UTF8STRING,
    ip          [0] UTF8STRING OPTIONAL,
    membership  [1] UTF8STRING OPTIONAL,
    bot         [2] UTF8STRING OPTIONAL
}
