【Android】Json 的建立

建立範例

{
    "type": "2",
    "body": {
        "description": [
            {
                "dns1": "140.113.17.5",
                "dns2": "140.113.1.1",
                "static": "1",
                "gateway": "140.113.17.254",
                "netmask": "255.255.255.0",
                "ip": "140.113.17.178"
            },
            {
                "dhcp": "0"
            },
            {
                "pppoe": "0"
            }
        ]
    },
    "deviceId": "BW-9FEFB676A5DC556C18D3D24D9FC334C4"
}


建立function

    /**
     * setWanInfoJson
     * @param responseJson
     */
    public String setWanInfoJson(Context ctx, String deviceId)  {

        JSONObject sendJson = new JSONObject();

        try {

            sendJson.put("type", "2");
            sendJson.put("deviceId", deviceId);


            // 構造三個JSONObject 、一個static, dhcp 和 pppoe物件
            JSONObject staticJson = new JSONObject();
            staticJson.put("static", "1");
            staticJson.put("ip", "140.113.17.178");
            staticJson.put("netmask", "255.255.255.0");
            staticJson.put("gateway", "140.113.17.254");
            staticJson.put("dns1", "140.113.17.5");
            staticJson.put("dns2", "140.113.1.1");

            JSONObject dhcpJson = new JSONObject();
            dhcpJson.put("dhcp", "0");

            JSONObject pppoeJson = new JSONObject();
            pppoeJson.put("pppoe", "0");

            // We add the object to the description Array
            JSONArray descriptionArr = new JSONArray();
            descriptionArr.put(staticJson);
            descriptionArr.put(dhcpJson);
            descriptionArr.put(pppoeJson);

            // We add the descriptionArr to the body object
            JSONObject body = new JSONObject();
            body.put("description", descriptionArr);

            // We add the object to the main object
            sendJson.put("body", body);



        } catch (JSONException e) {

            e.printStackTrace();
        }

        System.out.println("sendJson:" + sendJson.toString());

        return sendJson.toString();

    }
