如何从 SNMP 设备迭代对象并使用预定义规则创建可读输出

Question

我在 SNMP 设备中有以下 JSON：

mib = [
    "1.3.6.1.2.1.43.11.1": {
        "1.1": {
            "3": "1",
            "5": "3",
            "6": "Cyan Toner Cartridge, WorkCentre 6505N",
            "8": "2000",
            "9": "800"
        },
        "1.2": {
            "3": "2",
            "5": "3",
            "6": "Magenta Toner Cartridge, WorkCentre 6505N",
            "8": "1000",
            "9": "400"
        },
        "1.5": {
            "3": "0",
            "5": "9",
            "6": "Imaging Unit, WorkCentre 6505N",
            "8": "24000",
            "9": "24000"
        }
    },
    "1.3.6.1.2.1.43.12.1": {
        "1.1": {
            "4": "cyan"
        },
        "1.2": {
            "4": "magenta"
        }
    }
]

我想要的结果是这样的：

device["markerSupplies"]: [
    0: {
        color: "cyan",
        type: "toner",
        description: "Cyan Toner Cartridge, WorkCentre 6505N",
        capacity: "2000",
        value: "800"
    },
    1: {
        color: "magenta",
        type: "toner",
        description: "Magenta Toner Cartridge, WorkCentre 6505N",
        capacity: "1000",
        value: "400"
    },
    2: {
        color: "",
        type: "opc",
        description: "Imaging Unit, WorkCentre 6505N",
        capacity: "24000",
        value: "24000"
    },
]

“1.1”、“1.2”... 只是索引，我了解其中的内容。每一个属性在他们里面称为一个列并对应于它的索引。

我知道每个table的列：

1.3.6.1.2.1.43.11.1
    3   the color index inside 1.3.6.1.2.1.43.12.1
    5
        3   "toner"
        9   "opc"
    6   description
    8   capacity
    9   level

1.3.6.1.2.1.43.12.1
    4   color name

我如何创建一个 JSON 信息对象，使用 javascript 代码我可以从设备迭代 JSON 并创建我上面显示的输出结果？

Answer 1

您可以为颜色和类型使用一些辅助变量，并迭代键以构建新数组。

var mib = { "1.3.6.1.2.1.43.11.1": { "1.1": { 3: "1", 5: "3", 6: "Cyan Toner Cartridge, WorkCentre 6505N", 8: "2000", 9: "800" }, "1.2": { 3: "2", 5: "3", 6: "Magenta Toner Cartridge, WorkCentre 6505N", 8: "1000", 9: "400" }, "1.5": { 3: "0", 5: "9", 6: "Imaging Unit, WorkCentre 6505N", 8: "24000", 9: "24000" } }, "1.3.6.1.2.1.43.12.1": { "1.1": { 4: "cyan" }, "1.2": { 4: "magenta" } } },
    cols = { 3: 'color', 5: 'type', 6: 'description', 8: 'capacity', 9: 'level' },
    types = { 3: 'toner', 9: 'opc' },
    markerSupplies = mib['1.3.6.1.2.1.43.11.1'],
    colors = mib['1.3.6.1.2.1.43.12.1'],
    result = Object.keys(markerSupplies).map(function (k) {
        var o = {};
        Object.keys(cols).forEach(function (c) {
            if (c === '3') {
                o[cols[c]] = (colors[k] || {})['4'] || '';
                return;
            }
            if (c === '5') {
                o[cols[c]] = types[markerSupplies[k][c]] || '';
                return;
            }
            o[cols[c]] = markerSupplies[k][c] || '';

        });
        return o;
    });

console.log(result);
