Question

我目前正在使用SonicWall路由器。我正在尝试从项目中获取一些信息。我通过SSH连接到它，我选择了JSON作为输出格式来获取所有信息。我遇到的问题如下。对于简单命令，返回的内容非常简单，但对于更复杂的命令，返回的JSON可能无效。

以下是一个简短示例（这些是NAT政策）：

    {
    "success": true,
    "cli": [
        { "command": [ { "token": "nat-policy" }, { "token": "inbound" }, { "token": "X1" }, { "token": "outbound" }, { "token": "X1" }, { "token": "destination" }, { "token": "name" }, { "token": "WAN Primary IP" }, { "token": "service" }, { "token": "name" }, { "token": "SNMP" } ] },
        { "submode": [
            { "command": [ { "token": "id" }, { "token": "0" } ] },
            { "command": [ { "token": "inbound" }, { "token": "X1" } ] },
            { "command": [ { "token": "outbound" }, { "token": "X1" } ] },
            { "command": [ { "token": "source" }, { "token": "any" } ] },
            { "command": [ { "token": "translated-source" }, { "token": "original" } ] },
            { "command": [ { "token": "destination" }, { "token": "name" }, { "token": "WAN Primary IP" } ] },
            { "command": [ { "token": "translated-destination" }, { "token": "original" } ] },
            { "command": [ { "token": "service" }, { "token": "name" }, { "token": "SNMP" } ] },
            { "command": [ { "token": "translated-service" }, { "token": "original" } ] },
            { "command": [ { "token": "enable" } ] },
            { "command": [ { "token": "comment" }, { "token": "Management NAT Policy" } ] },
            { "command": [ { "token": "exit" } ] }
        ] },
      { "command": [ { "token": "end" } ] }
    ] }

据我所知，返回JSON包含一个字段＆＃34;成功＆＃34;和一个领域＆＃34; cli＆＃34;其中包含一个字段＆＃34;命令＆＃34;这是一个令牌列表和一个字段＆＃34; submode＆＃34;这是一个命令列表，每个命令都包含一个令牌列表。

我想删除字段＆＃34;命令＆＃34;以及它所持有的令牌列表，结果将是这样的：

{
"success": true,
"cli": [
    { "submode": [
        { "command": [ { "token": "id" }, { "token": "0" } ] },
        { "command": [ { "token": "inbound" }, { "token": "X1" } ] },
        { "command": [ { "token": "outbound" }, { "token": "X1" } ] },
        { "command": [ { "token": "source" }, { "token": "any" } ] },
        { "command": [ { "token": "translated-source" }, { "token": "original" } ] },
        { "command": [ { "token": "destination" }, { "token": "name" }, { "token": "WAN Primary IP" } ] },
        { "command": [ { "token": "translated-destination" }, { "token": "original" } ] },
        { "command": [ { "token": "service" }, { "token": "name" }, { "token": "SNMP" } ] },
        { "command": [ { "token": "translated-service" }, { "token": "original" } ] },
        { "command": [ { "token": "enable" } ] },
        { "command": [ { "token": "comment" }, { "token": "Management NAT Policy" } ] },
        { "command": [ { "token": "exit" } ] }
    ] }
] }

本质上我只想保留＆＃34;子模式＆＃34;带命令列表的字段。

我在Java中这样做，并且找不到一种方法来对返回的JSON进行子串，以获得预期的结果。任何人都可以帮忙吗？

您可以使用java jsonp：

JsonReader reader = Json.createReader(myJsonStream);
JsonObject obj = reader.readObject();

JsonBuilderFactory factory = Json.createBuilderFactory(null);
JsonObject myJson = factory.createObjectBuilder()
    .add("success", obj.get("success"))
    .add("cli", factory.createArrayBuilder()
        .add(factory.createObjectBuilder()
            .add("submode", obj.getJsonArray("cli").getJsonObject(1).get("submode")))).build();


FileOutputStream fs = new FileOutputStream("my_new_json_path");
JsonWriter wr = Json.createWriter(fs);
wr.writeObject(myJson);
wr.close();

绑定到你的json结构但是它有效！

从JSON中删除未使用的信息
